* 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 can be either SC or LC 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
This section presents Optical Insertion Loss values, and demonstrates their use in Optical Loss Budget calculations.
The Optical Insertion Loss examples included herein only consider the accumulated Insertion Losses that are contributed by the equipment
supplied by Canary Communications when deploying CWDM Multiplexer/De-Multiplexers and OADMs in a network. A complete Optical
Budget for the entire network should be calculated separately.
The following table lists the (path) Optical Insertion Losses through each class of Canary (four & eight channel) Multiplexer / De-Multiplexers and
OADMs that service one, two and four Client access-channel “Drops” & “Adds”. The tabulated Insertion Loss values are used for estimating the
combined Optical Power Losses incurred by an optical signal traversing a series of Passive CWDM Multiplexer or OADM stages.
