Coarse Wavelength Division Multiplexing
Single-Fiber, Bi-Directional CWDM Multiplexer/De-Multiplexers
Single-Fiber, Bi-Directional Multiplexer/De-Multiplexer versions
transport four user-channels across a simplex, (single-fiber) single-
mode strand. Each of the four user-channels employs two
wavelengths – one for outgoing data transmission and one for
incoming data reception. In practice, eight wavelengths are paired
in use and require two variants of Single-Fiber Multiplexer /De-
multiplexers to be linked as complementary pairs. One Single-Fiber
variant (SFA) transmits on Group-A wavelengths (λs) and receives
on Group-B wavelengths. The other variant (SFB) transmits on
Group-B wavelengths and receives on Group-A wavelengths.
Together, they form a complementary pair. One SFA version must
always be connected to one SFB version for the proper functioning
of Single-Fiber, Bi-Directional links. CCM-1600 SFA units can function
with any other standalone or CCN-2000 chassis based SFB
Multiplexers and visa versa. Single-Fiber multiplexers are ideal for
maintaining or increasing user access when available fiber is limited
to a single strand or is being redeployed for other uses.
Canary Single-Fiber, Bi-Directional Coarse Wavelength Division
Multiplexers use completely passive, un-powered, optical
components and are available as modules for both the CCM-1600
and CCN-2000 chassis media converter families and as standalone
versions.
