Connecting a Fiber Optic Link Segment to an
EPIM-F1, EPIM-F2, or EPIM-F3
EPIM-F1, EPIM-F2, or EPIM-F3
When connecting a fiber optic link segment to an EPIM-F1, F2, or F3
keep the following in mind:
keep the following in mind:
•
If you are connecting a fiber optic link segment with SMA 906
connectors to an EPIM-F1 with SMA ports, ensure that half alignment
sleeves are in place on each connector. A full alignment sleeve will
damage the receive port. SMA 905 connectors do not need alignment
sleeves.

•
If you are 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. The
connector is inserted into the port with the alignment key on the
connector inserted into the alignment slot on the port. The connector
is then turned 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 the applicable port on the module will be connected to the
Receive port of a fiber optic Ethernet device at the other end of the
segment. For example, TX of the applicable port on the module will go
to RX of the other fiber optic device. The Receive strand of the
applicable port on the module will be connected to the Transmit port
of the fiber optic Ethernet device. For example, RX of the applicable
port on the module will go to TX of the other fiber optic device.

We recommend that you label the fiber optic cable to indicate which
fiber is Receive and which is Transmit. When you buy fiber optic
fiber is Receive and which is Transmit. When you buy fiber optic
