Coarse Wavelength Division Multiplexing
CWDM Multiplexer Modules and Media Converters
The CCM-1600 Chassis Group includes Coarse Wavelength Division Multiplexer* modules
and CWDM Media Converters. Canary Communications’ approach to the CWDM solution is
outlined below, followed by ordering information for CCM-1600 Chassis Passive and Active
Modules. Users who would like a Coarse Wavelength Division Multiplexing overview will find
that discussion as one of the two appendices to this data-sheet. The other appendix provides
Optical Insertion Loss tables and examples of Optical Insertion Loss calculations.
The Canary Communications Coarse Wavelength Division
Multiplexing solution
Canary’s approach to the CWDM marketplace and its deployment
is derived from a simple premise based on the following beliefs:
• Any network using long distance single-mode fiber that needs
more bandwidth can benefit by deploying CWDM Technology.
•Deploying and using CWDM Technology does not require “new”,
complex, “fully integrated” processor hardware with all the “bells
and whistles”.
•A basic CWDM installation can deliver most of the benefits of a
much more complex one – at a much lower total cost of
ownership.
• An experienced network administrator/integrator has the requisite
skills to confidently deploy and use CWDM Technology.
•CWDM Technology does not mandate a rigid “one size fits all”
mentality or approach to its deployment– (it) is modular, highly
scalable, 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 Technology
is the solution.
• Deploying and using CWDM Technology does not have to be
complex.
• Deploying and using CWDM Technology does not have to be
expensive.
• Deploying and using CWDM Technology does not have to be
difficult.
•CWDM Technology should be used when network scalability,
flexibility, and cost are key.
NOTES
*Usage: Throughout this document the acronym CWDM is used in two contexts: It
encompasses Coarse Wavelength Division Multiplexing technology as a whole. Or
more narrowly, it can refer to Coarse Wavelength Division Multiplexer/De-Multiplexer
(mux/demux) hardware that optically combines transmitted wavelengths into a
multiplexed data stream or partitions them, when received, into individual channels.
