Tributary interfaces (X2S11TRIB card)
...................................................................................................................................................................................................................................
Purpose
These interfaces must be used for enabling 1+1 MSP protection.
NOTE: The X2S11TRIB card can only be used for 1643 AMS units which are
equipped with STM-4 interfaces.
Connector data
The tributary fiber connectors which are located on the X2S11TRIB option card are
equipped with SC connectors. If necessary, FC and ST adaptors can be used which are
supplied with the unit delivery.
Cable data
Single Mode (SM) fibers must be used.
Cable connection
Please connect the tributary fiber cables as shown in the figure below.
NOTE: The routing of the fibers should be in accordance with the specifications for the
selected fiber. Care should be taken not to exceed the bending radius of about 30 mm
when placing the fibers. Exceeding the recommended radius may cause distortion and
poor signal quality. All fibers should be strain relieved to prevent any force from being
exerted on the connectors. Clean all connections, as required, before attaching (see
Appendix A, “Fiber cleaning” (p. B-10)).
