Standard multi-mode fiber port connectors are designated by (21 or 22) e.g. (CFC-XX21) or (CFC-XX22) and have common power and sensitivity specifications.
Standard single-mode fiber port connectors are designated by (91 or 92) e.g. (CFC-XX91) or (CFC-XX92) and have common power and sensitivity specifications.

* NOTE: CFC-972XA/B, CFC-972XE4A/B, CFC-972XE6A/B standalone converters are available as card modules for Canary’s CCN-2000 / CCN-0400 and CCM-1600 chassis
models. Please refer to the CCM-1600 and CCN-2000 / CCN-0400 Data Sheets for more information.
More versions of the CFC-972XA/B series may be found on the Canary web site as they become available.

Canary’s multi-mode
to Single-Fiber, Bi-
Directional single-
mode converters
deliver Fast data
originating at low-
cost multi-mode
ports throughout the
enterprise via a
single strand of
single-mode fiber cable. CFC-972XA/B converters are designed to
free-up fiber capacity by using dual wavelengths transmitted bi-
directionally over a single strand of a duplex fiber pair. They are
ideal for data intensive backbones in the enterprise or across the
campus where extra fiber capacity is lacking but additional access is
needed for redundancy, to add channels, or for alternate protocols.
Canary’s Single-Fiber, Bi-Directional converters are functionally
identical to standard units with the exception that units designated
with an A transmit at 1550 ηm and receive on 1310 ηm, while B
Optical Specifications
units transmit at 1310 ηm and receive on 1550 ηm. Single-Fiber
converters must be connected as complementary A & B pairs. (A
and B units must be ordered in pairs because every A unit must be
connected to a B unit.) Similarly, standalone A & B units can be
connected to complementary A & B modules used in the CCN-
2000/0400 or CCM-1600 Chassis families. Canary Single-Fiber
converters are available with 20 kilometer, 40 kilometer or 60
kilometer transmission ranges.
