Connect Fiber Optic Cables

NOTE:
Always use the Cable Running List that accompanies the S8700 Multi-Connect
configuration when installing fiber optic cables. The following procedure is a typical
example of how to cable a S8700 Multi-Connect configuration.
If the media gateways are close together, the signal may go through a single, directly connected
fiber optic cable. If the media gateways are far apart, it may be easier to connect the media
gateways through an LIU or fiber shelf.
For each fiber indicated in the fiber optic Cable Running List:
Install a lightwave transceiver on the media gateway connector at the position in the
1
FROM column in the running list.
Select a cable indicated by the CABLE CODE and LENGTH in the running list. Connect
2
1 of the fibers to each connector on the lightwave transceivers just installed. The fiber is
numbered 1 or 2. The connector on the transceiver is labeled TX or RX. Keep track of
which fiber connects to which transceiver connector. Label both ends of these cables.
3 Route the fiber optic cables from the transceiver out of the media gateway. Secure the
cables to the cable-tie rack. Keep the fiber optic cables clear of the heavier I/O cables.
4 If the media gateway in the TO column in the running list is located remotely from the
FROM media gateway, connect to the TO media gateway by way of the LIU.
5 Install a lightwave transceiver on the media gateway connector at the position in the TO
column in the running list.
Route the cables from the FROM media gateway down into the cable trays of each PN
6
media gateway. Connect the cables to the lightwave transceiver just installed on the TO
media gateway.
7 Connect the fiber that comes from the TX connector of the FROM transceiver to the RX
connector of the TO transceiver and vice versa.
8 Route the cables through the media gateway and through cable organizers as provided.
Secure the cables to the cable-tie rack.

typical fiber optic cabling between media gateways. The cable between the EI and SNI on PN1
is a pre-installed metallic cable (H600-278).
If no running list is available, use the outer slots first in alternating order. Connect the
1
first 2 SNI slots to 3 and 20 (the left most and right most of the unused slots). Next, use 4
and 19, and so forth.
2 Add links to the PNs in alternating order (20, 3, 19, 4, 18, 5, and so forth).
