* Single-Fiber Bi-Directional, 4-channel Multiplexer/De-Multiplexers must be connected as complementary SFA & SFB pairs i.e. one SFA unit must be connected with one SFB unit to
establish a proper, functioning data link across the single-mode fiber cable.
All models of Passive Multiplexer / De-Multiplexers & OADMs use SC connectors as standard for single-mode network (loop) connections. Client ports are SC style fiber connectors.
There are eighteen CWDM wavelengths (λs) specified. Eight standard wavelengths plus four O-band λs are useable over most standard single-mode fiber. Canary offers products for the
standard eight wavelengths plus four O-band λs e.g. 1470, 1490, 1510, 1530, 1550, 1570, 1590, 1610 ηm + 1290, 1310, 1330, 1350 ηm
As noted earlier, optical insertion losses are an important consideration when planning for and ordering passive and active CWDM components.
The following table is for reference only. It lists the (path) Optical Isolation values through each class of Canary (four & eight channel) Multiplexer
/ De-Multiplexers and OADMs that service one, two and four Client access-channel “Drops” & “Adds”.
