    Coarse Wavelength Division Multiplexing

    Introduction

    The Canary Communications Coarse Wavelength DivisionMultiplexing solutionCanarys approach to the CWDM marketplace and its deploymentis derived from a simple premise based on the following beliefs:

    Any network using single-mode fiber that needs more bandwidthcan benefit by deploying CWDM Technology.

    Deploying and using CWDM Technology does not require new,complex, fully integrated processor hardware with all the bellsand whistles.

    A basic CWDM installation can deliver most of the benefits of amuch more complex one at a much lower total cost ofownership.

    An experienced network administrator/integrator has the requisiteskills to confidently deploy and use CWDM Technology.

    CWDM Technology does not mandate a rigid one size fits allmentality or approach to its deployment (it) is modular, highlyscalable, and is flexible enough to meet most user needs.

    These beliefs led to the following design principles:

    If more single-mode bandwidth is needed, CWDM Technologyis the solution.

    Deploying and using CWDM Technology does not have to becomplex.

    Deploying and using CWDM Technology does not have to beexpensive.

    Deploying and using CWDM Technology does not have to bedifficult.

    CWDM Technology should be used when network scalability,flexibility, and cost are key.

    Canary Communications approach to the CWDM solution is outlined below, followed byordering information for our Four and Eight-Channel Multiplexers/De-Multiplexers Single-Fiber, Bi-Directional CWDM Multiplexers/De-Multiplexers, Optical Add-Drop Multiplexers(OADMs), and Gigabit and Fast Ethernet Converters with ITU-specified CWDM wavelengths.Users who would like a CWDM overview will find that discussion as one of two Appendicesto this data sheet. The other Appendix provides examples of Optical Insertion Loss Calculations.

    Canarys premise is that users can enjoy the full benefit of CWDMTechnology, scaled to their exact needs, by using a simple, modular,building-block approach to its deployment. Canarys productdevelopment philosophy is to leverage the marketplaces familiarityand long experience with Media Converters and their use to makeCWDM Technology understandable, easily deployable, and, aboveall, economical to use.

    Canarys CWDM product offering implements the above premisesin the following ways:

    1. Canary offers a wide range of Multiplexer/De-Multiplexerequipment with access capability for four, eight, and twelve userdata-channels over duplex fiber, and four user channels over asingle fiber strand. The Multiplexers are available in various formfactors standalone/rackable chassis and as slide-in modulesfor our multi-port CCM-1600 and Manageable CCN-2000Converter Chassis families.

    2. Canarys selection of Optical Add/Drop Multiplexers (OADMs)allows one, two, or four user-channels to exit and return to aCWDM data stream at intermediate locations on the fiber ring.One class of two-channel OADMs enable newly inserted orchannel return-path data to propagate separately into twodirections. The fiber segment is effectively split into two virtualsegments at that point.

    Introduction

    3. Active Media Converters with CWDM transmitters providingseveral different power levels are available to provide CWDMaccess for users with standard UTP or Fiber connections. Protocolssupported by CWDM Conversion include Gigabit Ethernet, FastEthernet, and Fibre Channel.

    4. Modular CWDM Converter cards are available for the CanaryCCM-1600 and CCN-2000 chassis families.

    5. A CCM-1600 or CCN-2000 chassis can be configured with oneslide-in Multiplexer/De-Multiplexer Module and the neededMedia Converter Modules to convert standard interfaces toCWDM wavelengths. The resulting package will function as aself-contained unit.

    6. Canarys CWDM Converter Modules are backward-compatiblewith older installed multi-port Converters. If a Canary multi-portchassis is already installed, upgrading to full CWDM capability isas simple as installing a Multiplexer Module and changing a fewConverter Cards.

    The Canary CWDM and OADM products that follow reflect andapply this efficient, cost-effective, and user-friendly design anddevelopment philosophy.

    CR-XMDX-X Four and Eight-channel Optical Multiplexers/De-Multiplexers

    Canarys economical Coarse Wavelength Division Multiplexers(CWDMs) accomplish the process of combining and launching inparallel, multiple user data channels as a single, transmitted multi-wavelength data stream. The process uses completely passive, un-powered, optical components
