* NOTE 1: W-XX designates one of eight CWDM optical transmission wavelengths (λ) e.g. CFT-20W-47=1470ηm or CFT-20W-61=1610ηm transmission.
Please refer to other CWDM (Coarse Wavelength Division Multiplexing Data Sheets for additional information.
* NOTE 2: Canary CWDM standalone converters are available as card modules for the CCM-1600 and SNMP manageable CCN-2000 / CCN-0400 Chassis models.
Please refer to the CCM-1600 and CCN-2000 / CCN-0400 Data Sheets for more information.
Please refer to the Standalone / Rackable CWDM data pages for information on Passive Optical Multiplexer / De-Multiplexers and OADMs.
There are eighteen CWDM wavelengths (λs) specified. Eight standard wavelengths plus four O-band λs are usable over most standard single-mode fiber.
Canary offers products for the standard eight wavelengths plus four O-band λs: 1470, 1490, 1510, 1530, 1550, 1570, 1590, 1610 ηm + 1290, 1310, 1330, 1350 ηm
More versions of the CFT-20W-XX series may be found on the Canary web site as they become available.
Canary’s CFT-20W-XX series of Coarse Wavelength Division
Multiplexing (CWDM) converters provide an efficient way to launch
multiple Fast Ethernet channels for transport through CWDM
Multiplexers and provide access to high capacity CWDM based
networks.
Coarse Wavelength Division Multiplexing reduces network
congestion with a minimum infrastructure investment. Using discrete
wavelengths (one per channel), multiple data channels can be
transported in parallel over a single-mode fiber cable.
CFT-20W-XX converters are the first in the industry to speedup
Spanning Tree link recovery by employing Link Fault Signaling (LFS)
technology while supporting Far-End Fault-Indication and Parallel
Detection capabilities.
Canary’s CFT-20W-XX Coarse Wavelength Division Multiplexing
converters are designed to meet industry needs for an economical
way to access CWDM point-to-point campus and metro-ring
networks. They are used with Main Distribution Frame (central
office) Multiplexers and with remote site Optical Add/Drop
Multiplexers (OADMs) to insert and/or recover optical traffic from
single-mode fiber segments. Specific models provide transmission
on one of eight λs, each an ITU specified, CWDM wavelength.
Standard versions support 80 Kilometer transmission distances.

Autonegotiation for 100 Mbs, Full and Half-duplex operation
•Internal Auto-sensing, MDI / MDI-X crossover switch for
proper Network Interface Card or Switch connections
•Switch enabled Link Fault Signaling (LFS) – Forwards lost
link awareness to each connected host
•Optional: UK, Continental European power
•Auto-sensing, 100 / 240 VAC Power Supply
•A full array of diagnostic LEDs
CWDM converters are functionally identical to standard units with
the exception that units at opposite ends of a fiber link must be
models with identical wavelengths in order to maintain a common
channel link e.g. if one device is operating at 1470 ηm, the second
must transmit and receive on the same CWDM wavelength.
Similarly, a standalone 1470 ηm unit can be connected to a
CCM-1600 or CCN-2000 / CCN-0400 chassis module with the
same wavelength.
