Connecting OC-3 Cables
Connecting OC-3 Cables
This procedure applies to MGX 8260 nodes configured with SCC OC-3 back cards for fiber interface
Note
to Cisco MGX 8850 ATM switches. If your MGX 8260 node uses SCCs with Fast Ethernet back
cards, skip this section.
Each fiber interface consists of two fiber-optic cables—one for transmit signals and one for receive
signals. If the SCC is equipped with the single mode OC-3 back card, the fiber cables must be terminated
with LC type connectors at the MGX 8260. If the SCC is equipped with the multimode OC-3 back card,
the fiber cables must be terminated with MT-RJ type connectors at the MGX 8260.
Note
The transmit and receive fiber cables must be reversed at each device. The receive fiber cable from
the MGX 8260 goes to the transmit port at the other end, and vice versa.
When handling optical cables, observe the manufacturer's bend radius limits.
Caution
To connect the OC-3 fiber-optic cables, follow these steps:
Connect the first optical cable to the top receptacle of the SCC back card in slot 9 or 10 (See
Step 1
Step 2
Route the optical cable down and to the side of the chassis, observing the minimum bend radius for the
cable.
Connect the other end of the cable into the appropriate communication equipment.
