How to use this documentThis documentation suite details applications that involve dense-wavelength division multiplexing (DWDM) and multiwavelength optical repeater (MOR) or MOR Plus amplifiers. The MOR/MOR Plus amplifiers must be installed in an OC-192 network element shelf. This shelf can be running OC-192 software or OPTera Connect DX optical switch software (referred to as OPTera Connect DX in this document). In this document, unless expressly indicated otherwise, the statement “OC-192 Release x.0 and higher software” includes an OC-192 platform running any release of OPTera Connect DX software.

Note: In this document, the lower case “x” in a release or document reference is used to denote a variable number.


4-2 How to use the MOR Applications documentation

The network elements at either end of the optical link can be any of the following types:

• OC-48

• OC-192

• OC-192 as a platform of OPTera Connect DX (running OPTera Connect DX software)

• OPTera Connect DX (DX platform)

• hybrid systems including a mix of OC-48 or OC-192 (or Connect DX) network elements (a mix of OC-192 and OPTera Connect DX network elements is not considered a hybrid system)

The documentation you order depends on the type of network elements used in the system.

In addition to the MOR/MOR Plus Applications library, you require one of the following libraries to support the network element in which the MOR/MOR Plus is installed:

• If the MOR/MOR Plus is installed in an OC-192 network element running OC-192 Release 7 or earlier software, you require the OC-192 NE Library (323-1301-xxx).

• If the MOR/MOR Plus is installed in an OC-192 network element as a platform of OPTera Connect DX (running OPTera Connect DX software), you require the OPTera Connect DX library with the OC-192 platform option (323-1501-xxx and 323-1541-xxx).

You also require the appropriate OC-192, OC-48, and OPTera Connect DX NTP libraries according to the types of network elements in the DWDM configuration as follows:

• For OC-192 network elements running Release 7 or earlier software, use the OC-192 NE Library, 323-1301-xxx

• For OC-48 network elements, use the OC-48 NE Library, 323-1201-xxx

• For OC-192 as a platform of OPTera Connect DX (running OPTera Connect DX software), use the OPTera Connect DX library with the OC-192 platform option (323-1501-xxx and 323-1541-xxx)

• For OPTera Connect DX network elements, use the OPTera Connect DX library with the DX platform option (323-1501-xxx and 323-1521-xxx)

Where to beginBefore beginning, it is important to understand that an amplifier system is divided into two layers; the synchronous optical network (SONET) layer and the optical layer. The SONET layer deals with all of the equipment required to


How to use the MOR Applications documentation 4-3

form point-to-point links between SONET network elements. The optical layer deals with the optical infrastructure required to join all these SONET network elements and includes amplifiers and DWDM hardware.

The transition point between the SONET and optical layers is at the transmitters and receivers, both of which are important to each of the two layers in a different way. From the SONET layer perspective, the shelf configuration of the transmitters and receivers is important, to define the correct SONET architecture. From the optical layer perspective, the output power levels of the transmitters and the input power levels incident on the receivers are important, to ensure a well optimized DWDM link.

As an example, assume an OC-48 4-wavelength MOR system with one line amplifier site must be put in to service (as illustrated following). The transmitters and receivers are housed in OC-48 network elements and the MORs are housed in OC-192 network elements.

To start, the equipment at each site must first be installed. Installation of the network element bays is done according to the OC-48 or OC-192 installation documents as follows:

• Installation Procedures, 323-1201-201, for OC-48

• Installation Procedures, 323-1301-201, for OC-192 Release 7.0 or earlier software

• Installation Procedures, 323-1541-201, for OC-192 as a platform of OPTera Connect DX (running OPTera Connect DX software)

• Installation Procedures, 323-1521-201, for OPTera Connect DX network elements

Installation of the required DWDM-specific equipment, such as couplers and dispersion compensating modules (DCM), is done using the procedures in Appendix A of MOR SLAT and Upgrade Procedures, 323-1251-220.

Note: Installation of DWDM couplers not in the Nortel Networks DWDM coupler shelf, is the responsibility of the customer.



With the equipment installed, the system is ready to be commissioned. This includes all of the tasks necessary to bring a new system into steady-state operation. It involves system lineup and testing (at both the SONET and optical levels) and network element provisioning.

In our documentation, commissioning begins at the SONET level at the line-terminating equipment (LTE) site housing the RED transmitters. (You can, however, begin at the LTE housing the BLUE transmitters by substituting BLUE for RED.) In this particular example, this point of the process would require that the procedures in the OC-48 document, Commissioning Procedures, 323-1201-220, be performed for the network elements housing the transmitters and receivers, and that the procedures in the OC-192 document, Powering-up and Commissioning Procedures, 323-1301-220 or 323-1541-220, be performed for network elements housing the MORs.

After commissioning is performed for each network element at the site, site testing of the network element(s) is required. Site testing is performed using the procedures in the OC-48 or OC-192 site testing documents as follows:

• Site Testing Procedures, 323-1201-221, for OC-48

• Site Testing Procedures, 323-1301-221, for OC-192 Release 7.0 or earlier software

• Site Testing Procedures, 323-1541-221, for OC-192 as a platform of OPTera Connect DX (running OPTera Connect DX software)

• Site Testing Procedures, 323-1521-221, for OPTera Connect DX network elements

Note: Not all network elements need to be site tested. The procedures indicate when it is required.

After each network element at the site is tested at the SONET level, optical link engineering for the system is performed (if not already done) using the appropriate chapter in one of the following documents:


• 100 GHz, MOR Plus, 2 to 32-λ Optical Layer Applications Guide (NTY312DX)


• MOR Optical Layer OAM&P, 323-1251-100

Following that, is optical system lineup of the site, according to information and procedures in MOR SLAT and Upgrade Procedures, 323-1251-220.

Once optical system lineup has been performed at the first site, the technicians move to the next site in the system, and so on until system lineup and testing has been completed at all sites. At that point, the system will be fully connected. MOR system equalization and end-to-end testing is then performed. These tasks are also provided in MOR SLAT and Upgrade Procedures, 323-1251-220.

With the MOR system equalized and tested optically end to end, SONET end-to-end commissioning and testing is performed. In this example, the OC-48 system is the primary (transmit/receive) system, and so the procedures in the OC-48 document, System Testing Procedures, 323-1201-222, would be used.

Note: End-to-end commissioning is unique to OC-192 systems only. As a result, in this example, end-to-end commissioning does not apply.

Once SONET end-to-end testing is complete, the system can be put into service. From that point forward, provisioning of system parameters and system administration is performed. Provisioning customizes the network elements and the signal parameters to meet the system requirements. System administration involves management of software, data, and system security. Again since this example involves an OC-48 SONET system, the procedures on how to perform these tasks are found in the OC-48 documentation suite.



Maintenance procedures for the OC-48, OC-192, and OPTera Connect DX sections of the system can be found in the appropriate documents of the OC-48, OC-192, and OPTera Connect DX documentation suites. Maintenance procedures for the MOR section of the system can be found in the appropriate chapter of MOR Alarm Clearing and Module Replacement, 323-1251-543.

High-level procedure introductionThe documents in this library contains high-level procedure introductions that provide information necessary for an experienced user to perform a procedure (as illustrated in the following example). The procedure purpose, requirements, main procedure tasks, and expected results are consolidated into one section of two pages at the most. The step numbers in parenthesis provide links to specific procedure steps within the complete (detailed) procedure.

Some detailed procedures can include warning, caution, or danger messages imbedded in the steps. These precautionary message icons are also included (next to the applicable step) in the high-level introduction. To read the full precautionary message, refer to corresponding detailed step enclosed in parenthesis. In the following example, task item 5 includes a danger symbol. To read the message associated with this danger symbol, refer to step 7 of the detailed procedure.



Table 1Example of a high-level procedure

Procedure purpose

• Use this procedure to track down high reflections (low return losses) over an optical link under the following circumstances:

— the optical return loss at the output of a MOR or MOR Plus circuit pack is less than 24 dB

— dribbling errors are being counted and a soiled or poorly mated connector is suspected

Procedure tasks

1 For systems carrying live traffic, verify that traffic has been switched to protection (step 1).

2 If necessary, perform a forced protection switch (step 2).

3 Record the power settings for the MOR or MOR Plus circuit pack showing high reflections (step 3).

4 Provision the RED and BLUE output power targets to –20 dBm (step 6).

5 Unseat the MOR or MOR Plus circuit pack and clean the connectors on the faceplate (step 7).

6 Reinsert the circuit pack (step 10).

7 Reprovision the RED and BLUE output powers to their link design levels (step 11).

8 Verify the optical return loss (ORL) of the RED and BLUE directions is ≥ 24 dB (see MOR Provisioning Procedures, 323-1251-310) (step 12).

• If the ORL is < 24 dB, check if the high reflections are originating from the MOR or MOR Plus connection point (step 13). If high reflections are originating from the MOR or MOR Plus connection point, screen the MOR or MOR Plus for high reflections using Procedure 7-2, “Screening an MOR or MOR Plus for high reflections”.

• If you did not find high reflections originating from the last fiber connection point you tested, check for high reflections at the next fiber connection point (step 20). Continue with the remaining fiber connection points until you find the source for high reflections.

Note: If you suspect that the reflections originate from beyond the local site (that is, somewhere along the fiber span), you can use an optical time domain reflectometer (OTDR) to find out the exact location.

9 Release the appropriate protection switches (step 36).

Expected results

• The source of high reflection is found.

• If the expected results do not occur, contact your next level of support.



Summary of application and feature compliancy

Channel Autodiscovery The Channel Autodiscovery feature provides a mechanism to view and provision automatically all wavelength payloads that are being transmitted through an optical amplifier facility. The provisioned data can be propagated to all other amplifier sites automatically.

The feature dramatically reduces the time required to turn up a new network or to add new wavelengths to an existing network.

The Channel Autodiscovery feature is available on OC-192 Release 7.0 and higher, including OPTera Connect DX software.

Channel Provisioning Propagation

The user can send a command to the MOR or MOR Plus to propagate the post-amplifier channel provisioning to all amplifiers in the chain (that is, beginning with a post-amplifier and terminating with the first pre-amplifier along the optical path).

The feature dramatically reduces the time required to provision the network.

The Channel Provisioning Propagation feature is available on OC-192 Release 7.0 and higher releases, including OPTera Connect DX software.

Output Power Propagation The Output Power Propagation feature provides a mechanism for the MOR or MOR Plus circuit pack to control the output powers to provisionable targets. There are two modes of control and they are referred to as total power control mode and peak power control mode. The mode of control is also provisionable.

In total power control mode the total output power is controlled to the total output power target.

In peak power control mode, the power of the strongest constituent output channel originating from a provisioned DWDM transmitter with analog maintenance (AM) is controlled to the peak output power target. The powers of the individual wavelengths with AM are measured by the channel power detection feature.

The feature dramatically reduces the time required to provision the network.

The Output Power Propagation feature is available on OC-192 Release 7.0 and higher releases, including OPTera Connect DX software.

Received Optical Performance Monitoring Command Interpreter

The Received Optical Performance Monitoring Command Interpreter (ROPMCI) tool displays both the current and baseline values of the indicator of quality of the received signal for a specific circuit pack. The baseline values are stored in the network element database and are preserved over restarts, upgrades, and power outages.

The ROPMCI tool is available on OC-48 Release 15 and later releases. Receiver power monitoring in dBm is available on OC-48 Release 16.1 and higher releases with NT8E02DF OC-48 receivers.



Summary of document content and compliancyThe following table identifies the support of each of the documents in this library. In the following table, software releases higher than OC-192 Release 7.0 include OC-192 as a platform of OPTera Connect DX running OPTera Connect DX software. OC-48/OC-192 hybrid systems include OPTera Connect DX systems as an OC-192 system.

System lineup and testing (MOR SLAT and Upgrade Procedures, 323-1251-220)

The SLAT procedures in this document can be used for the following systems:

• 2 to 8-λ 200 GHz OC-48 and OC-192 systems running MOR OC-192 Releases 3.0 or 4.0 and are equipped with DWDM transmitters with analog maintenance (AM)

• 2 to 16-λ 200 GHz OC-48 and OC-192 systems running MOR OC-192 Release 5.0, 6.0, 7.0, or higher and are equipped with DWDM transmitters with AM

• 2 to 16-λ 200 GHz OC-48 and OC-192 systems with DWDM transmitters without AM

• 2 to 16-λ 200 GHz OC-48/OC-192 hybrid systems with DWDM transmitters with or without AM

• 2 to 32-λ 100 GHz OC-48, OC-192, and OC-48/OC-192 hybrid systems with DWDM transmitters with AM

The SLAT procedures support one 2 or 4-λ optical add/drop multiplexing (OADM) site, and connection of per band access couplers.

Guidelines for SLAT of 2-λ OC-192 systems with broadband transmitters and 2 to 4-λ OC-48 systems with direct mod transmitters, are provided in Appendix B.

Upgrading an MOR system(MOR SLAT and Upgrade Procedures, 323-1251-220)

There are several upgrade procedures in this document, as follows:

• Upgrading the bandwidth capacity of a multiwavelength optical repeater (MOR), MOR Plus, or mixed amplifier (MOR and MOR Plus) system by experienced maintenance personnel - provides significant time reduction compared to other upgrading procedures by interleaving the equalization of the RED and BLUE bands.

• Upgrading system capacity - two upgrade procedures are supported. The protection switched method supports upgrades from 2 to 32 λ on OC-48, OC-192 and OC-48/OC-192 hybrid systems. Furthermore, this procedure supports the addition of one 2 or 4-λ OADM site. The OADM couplers can be installed at a line-amplifier site (2-λ OADM only) or at an OADM DCM sandwich site (2 or 4-λ OADM).

The non-protection switched (in-service) method supports upgrades from 2 to 16 λ on OC-192 MOR systems and mixed amplifier systems.

The non-protection switched (in-service) method supports upgrades from 2 to 32 λ on OC-192 MOR Plus systems.

• Upgrading to a PBA system - this procedure supports the addition of per band access functionality to MOR systems.

Channel removing(MOR SLAT and Upgrade Procedures, 323-1251-220)

Channel removing procedures support drops from 4 to 16-λ in OC-48, OC-192, and OC-48/OC-192 hybrid systems.

—continued—




System equalization(MOR SLAT and Upgrade Procedures, 323-1251-220)

Two methods of system equalization are supported in this document. They include:

• Power optimization - this method can be used by OC-48, OC-192, or OC-48/OC-192 hybrid systems that meet the following criteria:

— are equipped with only MOR, only MOR Plus, or mixed amplifiers (MOR and MOR Plus)

— have MOR bays running OC-192 Release 3.0 or higher

— are equipped with transmitters with analog maintenance (AM)

— have no more than 4 λ in each band, for Release 3.0 and 4.0

— have no more than 8 λ in each band, for Release 5.0 and 6.0

— have no more than 16 λ in each band, for Release 7.0 or higher

— have a bidirectional optical service channel (OSC)

The power optimization feature is an automated method of system equalization. This method supports a full range of span losses. However, system performance is only guaranteed when the START method is used.

If the criteria for this method is not met, the START method must be used.

• Sequential transmitter attenuation and receiver test (START) - this method can be used by any OC-48, OC-192, or OC-48/OC-192 hybrid system with 4 to 16 λ. This method guarantees full system performance (takes noise and distortion into account), and must be used when the criteria for the power optimization method is not met.

For OADM systems, the START method can be performed by one of two methods. The “glass-through” method allows equalization to be performed from multiplexer/demultiplexer sites only. It requires that spare hardware be equipped at the multiplexer/demultiplexer sites, for asymmetric OADM links and does not account for the lower OSNR requirement for OADM channels.

The “analogous-channel” method requires equalization at both the multiplexer/demultiplexer and OADM sites, but does not require spare hardware for asymmetric links, and accounts for the lower OSNR requirement for OADM channels.

—continued—





Provisioning(MOR Provisioning, 323-1251-310)

The provisioning procedures in this document support MOR and OC-192 DWDM transmitter provisioning in OC-192 Releases 1.4 or higher (MOR Plus provisioning is provided in Release 5.0 and higher only).

Trouble clearing and module replacement(MOR Alarm Clearing and Module Replacement, 323-1251-543)

Alarm clearing procedures support OC-48, OC-192, and OC-48/OC-192 hybrid systems with DWDM transmitters. MOR alarms are provided with reference to OC-48 and OC-192 alarms in the respective OC-48 and OC-192 main documentation suites.

A transmitter-sparing procedure is also provided. This procedure makes use of the sparing channels supported in the Nortel Networks DWDM wavelength plan.

Installation (MOR SLAT and Upgrade Procedures, 323-1251-220)

Installation for DWDM and MOR hardware is provided. Installation of a mounting bracket for fixed-attenuation pads is also provided.

Ordering information(MOR Optical Layer OAM&P, 323-1251-100)

Ordering information for hardware used in MOR applications is provided. Included is information on transmitters, MOR and MOR Plus circuit packs, DWDM couplers, DCMs, fixed pads, and other hardware.
