3.9.3Connecting to an EPIM-F1/F2, or EPIM-F3

When connecting a fiber optic link segment to an EPIM-F1/F2, or EPIM-F3 keep the following in mind:

•When connecting a fiber optic link segment with SMA 906 connectors to an EPIM-F1 with SMA ports, make sure each connector uses half alignment, NOT full alignment, sleeves.

NOTE

A full alignment sleeve damages the receive port. SMA 905 connectors do not need alignment sleeves.

•When connecting a fiber optic link segment with ST connectors to an EPIM-F2 with ST ports, keep in mind that ST connectors attach to ST ports much like BNC connectors attach to BNC ports. Insert the connector into the port with the alignment key on the connector inserted into the alignment slot on the port. Turn the connector to lock it down.

•The physical communication link consists of two strands of fiber optic cabling: the Transmit (TX) and the Receive (RX). The Transmit strand from a module port connects to the Receive port of a fiber optic Ethernet device at the other end of the segment (i.e., TX of the applicable port on the module goes to RX of the other fiber optic device). The Receive strand of the applicable port on the module connects to the Transmit port of the fiber optic Ethernet device (i.e., RX of the applicable port on the module goes to TX of the other fiber optic device).
