Clear-Com HX System Frames - Manual (Page 82)

Each fiber card link comprises:
• A front card with status indicators.
• A rear card with two Duplex LC terminated fiber optic connectors
(TXVRA and TXVRB).
E-FIB cards use 9/125µ single mode fiber optic cables. On the rear card, the TX1/RX1
connector is used for the main ring and the TX2/RX2 connector is used for the secondary
ring. Single mode 9/125µ fiber optic cable should be used for connections and the matrices
should be wired up with the system, with the lowest IP address being system 1.
Note:
The standard maximum node length for fiber card connections is 10km, but other distances
are available to special order.
The order of the fiber optic cable connections is reversed between the front and rear panels:
• On the front panel the primary connection is the upper set of indicators. The
secondary connection is the lower set of indicators.
• On the rear panel the lower connector is the primary connection. The secondary
connection is the upper connector.
Care should be taken when connecting or disconnecting the cables to ensure that they are
connected correctly and not reversed.
A protective plug is usually fitted to the fiber connector sockets to protect
them from damage or the entry of foreign materials. These should only be
removed in order to fit the fiber optic cable. They should be replaced if the
cable is unplugged.
