INSTALLATION
3.5.5 Connecting Fiber Optic Link Segments
When connecting a fiber optic link segment to a SPIM-F1 or a
SPIM-F2, you must keep the following in mind:
•
If you are connecting a fiber optic link segment with SMA 906
connectors to a SPIM-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 a SPIM-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.
It is recommended that you label the fiber optic cable to indicate
which fiber is Receive and which is Transmit. When you buy
fiber optic cable from Cabletron Systems, it is labeled so that: at
one end of the cable, one fiber is labeled 1, and the other fiber is
labeled 2. This pattern is repeated at the other end of the cable.
If you did not purchase your cable from Cabletron Systems, be
sure you have labeled your cable in the manner described above.
CAUTION: Do not touch the ends of the fiber optic strands, and do
not let the ends come in contact with dust, dirt, or other contaminants.
Contamination of the ends can cause problems in data transmissions.
If the ends become contaminated, clean them with alcohol using a soft,
clean, lint free cloth.
