1. About This Guide

This document describes the main features, components, and specifications of the FibeAir 1500HP/RFU-HP system.

2. Target Audience

This manual is intended for use by Ceragon customers, potential customers, and business partners. The purpose of this manual is to provide basic information about the FibeAir 1500HP/RFU-HP for use in system planning.



3. 1500HP/RFU-HP General Description

The FibeAir 1500HP/RFU-HP is a high transmit power RFU designed for long haul applications with multiple carrier traffic. Together with its unique branching design, 1500HP/RFU-HP can chain up to five carriers per single antenna port and 10 carriers for dual port, making it ideal for Trunk or Multi Carrier applications. The 1500HP/RFU-HP can be installed in either indoor or outdoor configurations.

The field-proven 1500HP/RFU-HP was designed to enable high quality wireless communication in the most cost-effective manner. With tens of thousands of units deployed worldwide, the 1500HP/RFU-HP serves mobile operators enabling them to reach over longer distances while enabling the use of smaller antennas. The RFU-HP also includes a power-saving feature (“green mode”) that enables the microwave system to automatically detect when link conditions allow it to use less power.

1500HP and RFU-HP 1RX support Space Diversity via Baseband Switching in the IDU (BBS). 1500HP 2RX, supports Space Diversity through IF Combining (IFC). Both types of Space Diversity are valid solutions to deal with the presence of multipath.

Note: 1500 HP (11 GHz) 40 MHz bandwidth does not support IF Combining. For this frequency, space diversity is only available via BBS.

The RFU-HP 1RX offers full support for 3.5M-56MHz channels.

The RFU-HP 1RX supports the green-mode feature

Both systems are fully compatible with all OCB and ICB devices.

1 1500 HP (11 GHz ) 40 MHz bandwidth does not support IF Combining. For this frequency,

space diversity is only available via BBS.



4. 1500HP/RFU-HP System Configurations

4.1 Split Mount and All indoor

The 1500HP/RFU-HP radios can be installed either in split mount or in all indoor configurations.

The following configurations are applicable for Split-Mount or all indoor installations:

Unprotected N+0 - 1+0 to 10+0 – Data is transmitted through N channels, without redundancy (protection)

Hot Standby - 1+1 HSB, 2+2 HSB – Two RFUs use the same RF channel connected via a coupler. One channel transmits (Active) and the other acts as a backup (Standby). A 2+2 HSB configuration uses two RFUs which are chained using two frequencies and connected via a coupler to the other pair of RFUs.

N+1 Frequency Diversity - N+1 (1+1 to 9+1) – Data is transmitted through N channels and an additional (+1) frequency channel, which protects the N channels. If failure or signal degradation occurs in one of the N channels, the +1 channel carries the data of the affected N carrier. Additional configurations, such as 14+2, can be achieved using two racks.

Notes:

Space Diversity can be used in each of the configurations.

When using BBS for SD (1500HP 1RX/RFU-HP), ACM is not supported.

When the 1500HP/RFU-HP is mounted in a Split-Mount configuration, up to five RFUs can be

chained on one pole mount (the total is ten RFUs for a dual pole antenna).

When the 1500HP/RFU-HP is installed in an All Indoor configuration, there are several installation options:

In ETSI rack – up to ten radio carriers per rack

In 19” open rack – up to five radio carriers per subrack

Compact assembly – up to two radio carriers in horizontal placement (without a subrack)

Two types of branching options are available for all indoor configurations:

Using ICBs – Vertical assembly, up to 10 carriers per rack (five carriers per subrack)

Using OCBs – Compact horizontal assembly, up to 2 carriers per subrack



4.2 Space Diversity

In long distance wireless links, multipath phenomenon commonly exist, whereby fading occurs over time, space, and frequency. The 1500HP RFU provides two types of Space Diversity optimizations, which are ideal solutions for the multipath phenomenon:

IF Combining (IFC)

BBS (Base Band Switching)

The RFU-HP supports BBS Space Diversity, but not IFC.

Space Diversity with Multiple RFUs Space Diversity with Single RFU

4.2.1 IF Combining (IFC) Mechanism

FibeAir 1500HP includes an IF combining mechanism, which uses an innovative digital optimization algorithm to combine the signals received from both antennas in order to improve signal quality. When distortion occurs, it is measured in both receiver paths, and a new combined signal is produced. This can improve the system gain by up to 3 dB. IFC Space Diversity can be used with single and multiple RFUs.

A delay calibration for the diversity waveguide is required and is performed automatically via the NMS.

Each 1500HP has built-in IFC Space Diversity functionality, with one transmitter and two receivers. The receivers receive two different signals from two antennas, which are installed 10-20 meters apart.

There are two options for connecting the RFUs to the diversity antennas:

Waveguide to coaxial cable – Uses a waveguide adaptor (CPR type) connected to an N-type coaxial cable. This is the default option.

Elliptical waveguide – Uses a waveguide connector (CPR type) with an elliptical waveguide.



4.2.2 Baseband Switching (BBS)

Both FibeAir 1500HP and FibeAir RFU-HP support BBS Space Diversity. In this option, there are two RFUs instead of a single RFU with two receivers.

The actual BBS Space Diversity switching is performed in the IDU. The modem switches to the other RF signal when interference occurs, and returns to the main signal when the interference is gone. In this way, the system performs optimum signal receiving by using the signal that provides the best performance.

Note: When using BBS for SD (1500HP 1RX/RFU-HP), ACM is not supported



5. Split Mount Configuration and Branching Network

For multiple carriers, up to five carriers can be cascaded and circulated together to the antenna port.

Branching networks are the units which perform this function and route the signals from the RFUs to the antenna. The branching network can contain multiple OCBs or ICBs. When using a Split-Mount or All-Indoor compact (horizontal) configuration, the OCB branching network is used. When using an All-Indoor vertical configuration, the ICB branching network is used.

The main differences in branching concept between the OCB and the ICB relate to how the signals are circulated.

OCB – The Tx and the Rx path circulate together to the main OCB port. When chaining multiple OCBs, each Tx signal is chained to the OCB Rx signal and so on (uses S-bend section). For more details, refer to 1500HP/RFU-HP OCBs on page 17.

ICB – All the Tx signals are chained together to one Tx port (at the ICC) and all the Rx signals are chained together to one Rx port (at the ICC). The ICC circulates all the Tx and the Rx signals to one antenna port. For more information, refer to Indoor Circulator Block (ICB) on page 26.

All-Indoor Vertical Branching Split-Mount Branching and All-Indoor Compact



5.1 1500HP/RFU-HP OCBs

The OCB (Outdoor Circulator Block) has the following main purposes:

Hosts the circulators and the attached filters.

Routes the RF signal in the correct direction, through the filters and circulators.

Enables RFU connection to the Main and Diversity antennas.

FibeAir 1500HP and RFU-HP supports two types of OCBs:

OCB (Older Type)

New OCB

Old OCB New OCB

5.1.1 Old OCB

The Older Type OCB has two types, Type 1 and Type 2. The difference between the two types is the circulator direction. Depending on the configuration, OCB Type 1 or Type2 is used together with waveguide shorts, loads, U Bends, or couplers.

Each OCB has four waveguide access points: two in the front, and two at the rear. The diversity access point is optional.

If the system is not configured for diversity, all the relevant access points on the OCB must be terminated using waveguide shorts.

The two OCB types (with and without IFC Space Diversity) have different part numbers.



The following block diagrams show the difference between the two OCBs and the additional Diversity Circ block which is added in some diversity configurations.

Old OCB – Type 1

Old OCB – Type 1 and Type 2 Description



5.1.2 New OCB

The new OCB is optimized for configurations that do not use IFC Space Diversity. To support IFC Space Diversity, a diversity block is added.

The new OCB has only one type, and can be connected to an antenna via a flexible waveguide.

The new OCB connection is at the rear of the OCB. It includes proprietary accessories (different than those used for the older OCB).

Each OCB has three waveguide access points: The In/Out port is located at the rear of the OCB.

The OCB ports include:

Tx port

Rx Port

Diversity port

If the system is not configured for diversity, all the relevant access points on the OCB must be terminated using waveguide shorts. Unused Rx ports are terminated with a 50 ohm termination. New OCB and DCB Block Diagram

New OCB components include the following:

RF Filters

RF Filters are used for specific frequency channels and Tx/Rx separation. The filters are attached to the OCB, and each RFU contains one Rx and one Tx filter. In an IFC Space Diversity configuration, each RFU contains two Rx filters (which combine the IF signals) and one Tx filter. The filters can be replaced without removing the OCB.



DCB (Diversity Circulator Block)

THE DCB is an external block which is added in IFC Space Diversity configurations. The DCB is connected to the diversity port and can chain two OCBs.

Coupler Kit

The coupler kit is used for 1+1 Hot Standby (HSB) configurations.

U Bend

The U Bend connects the chained DCB (Diversity Circulator Block) in N+1/N+0 configurations.

S Bend

The S Bend connects the chained OCB (Outdoor Circulator Block) in N+1 /N+ 0 configurations.

Pole Mount Kit

The Pole Mount Kit can fasten up to five OCBs and the RFUs to the pole. The kit enables fast and easy pole mount installation.

5.3 Upgrade Procedure

The following components need to be added when upgrading from a 1+0 to an N+1 Split-Mount configuration:

• OCBs

• RFUs

• IDU/IDMs

• Flexible waveguides

When adding RF channels or carriers, RFUs and OCBs with specific filters need to be added as well.

The OCBs are chained together using couplers (for the same frequency) or U bends/S bends (for different frequencies), in accordance with the specific configuration.

Open ports on the OCBs are terminated with 50 ohm terminations.



Detailed upgrade procedure documents are available for specific configurations.

Please note that legacy OCBs can be upgraded and cascaded with the new OCB. Please contact your Ceragon representative for details.



6. All Indoor Configurations and Branching Network

All-Indoor configurations are when all the equipment is installed indoors (room, shelter) and an elliptical waveguide connects the radio output port from the room to the antenna.

A basic block diagram for a trunk system, including the main blocks, is shown in the following figure. The block diagram includes marked interface points which shall serve as reference points for several technical parameters used in this document.

Block Diagram of Trunk System

All-Indoor System with Five IP-10 Carriers



All-Indoor System with Ten IP-10 Carriers

The branching concept (as described in Split Mount Configuration and Branching Network on page 16) is similar to All-Indoor application.

When using All-Indoor configurations, there are two types of branching implementations:

Using ICBs – Vertical assembly, up to 10 carriers per rack (five carriers per subrack).

Using NEW OCBs – Compact horizontal assembly, up to two carriers per subrack.

All-Indoor Installations



6.1 RFU Subrack Components

Subrack for ETSI Rack

6.1.1 Subrack

The subrack hosts all the RFU components and connections, as shown in the previous figure.

The subrack includes up to five RFUs per subrack (each RFU connects to an ICB).

RFU with Branching



6.1.2 Indoor Circulator Block (ICB)

Each RFU is connected to one ICB, and several ICBs are chained to each other. The chained ICBs carry different RF channels and are connected to a single ICC, which sums the RF signals.

The main ICB functions include:

Hosts the circulators and filters.

Routes the RF signals in the correct direction, via the filters and circulators.

The ICB is a modular standalone unit. When system expansion is necessary, additional ICBs are added and chained with the existing ICBs.

The branching chain to neighbor ICB goes through the holes at the side. A long screw connects the ICBs to each other and the last ICB at the chain is terminated with a 50ohm termination, as shown below.

Note: The diversity port does not need to be terminated if the diversity filter is not attached to the ICB.

ICB Branching Chain

6.1.3 RF Filters

The RF Filters are used for specific frequency channels and Tx/Rx separation. The filters are attached to the ICB, and each RFU contains one Rx and one Tx filter.

In an IFC Space Diversity configuration, each RFU contains two Rx filters to combine the IF signals, along with one Tx filter.



6.1.4 Indoor Combiner Circulator (ICC)

The ICC does not perform space diversity ICB summing (single output port).

ICC

The ICC sums the Rx and Tx signals and combines the N channels to the output ports (one or two, in accordance with the configuration).

6.1.5 Indoor Combiner Circulator Diversity (ICCD)

The ICCD performs space diversity ICB summing (two output ports).

ICCD

6.1.6 Patch Panel

The ICB’s IF and XPIC cables are connected to the patch panel. The IDU’s IF cables are connected to the specific RFU location. An XPIC cable is used between two RFUs which are using the same Tx and Rx filters with different polarizations (V and H).



6.1.7 Fan Tray

The fan tray contains eight controlled and monitored fans, which cool the RFU heat dissipations. The fan tray is a tray which is part of ETSI rack (as shown above), while when using a 19” frame rack a fan tray is a separate unit which must be assembled separately (shown below).

6.3 All-Indoor Rack Types

Three types of racks can be used in an all-indoor configuration:

19” lab rack ( open frame )

19” rack

ETSI rack

The 19” rack is not commonly used in Ceragon configurations.

The 19” lab rack (open frame) contains a subrack that is preassembled at the factory and then shipped. The customer can also use an existing rack and the subrack is installed separately at the site.

7.2 Power Distribution Unit (PDU)

The PDU distributes the power supply (-48V) from the main power input to the relevant IDU. The PDU is preassembled and wired in an ETSI rack and is provided separately, when required, for a 19” lab rack. When ordering a 19” configuration, there are two rack assembly options:

19” lab rack provided separately

19” lab rack provided by the customer

For both options, a PDU for 19” can be provided upon request.

There are two types of PDU. The default PDU which has been assembled with each ETSI rack contains:

Two main switches – one for each five IDU carriers

Two FAN tray switches

1A. The default PDU which is assembled with the ETSI rack has a special addition of a plastic cover.

For special cases, when PDU protection is required, a PDU with plastic protection cover can be provided.

The PN for this PDU with protection cover is: 32T-PDU_CVR.



A PDU which distributes 10 x DC signals, the PDU type can be preassembled with an ETSI Rack and needs to be specially ordered because it is not the default PDU.
