Figure 50 LC connector

Connecting fiber

Step 1: Plug one end of the fiber into the SFP optical module of the Switch 8800

Family.

Step 2: Connect the other end of the fiber into the corresponding device.

c CAUTION: When the optical interface has not been connected with a fiber connector or its dust-proof mesh is open, there might be some invisible radiation emitted from the optical interface. So do not look into the optical interface directly.

Cover the optical interface if there is no connector plugged in.

Cable Routing

Recommendations

Freestanding Switch on For only selling an integrated chassis, you do not have to care about the cabling Tabletop inside or outside the cabinet. All the I/O module cables are routed from the left

side of the chassis (along the cabling channel), and the chassis power cords (AC/DC power cords) are routed in the front of the chassis.

Cabinet-MountingIf the switch is mounted in a 19-inch standard cabinet or B68-22 cabinet, the I/O Switch module cables are bound on the cabling rack at the left side of the chassis and are routed up or down to pass through the chassis top or the raised floor depending

on the available equipment room condition (that is, the signal cables are routed into the chassis either from the cabling rack on the chassis top or from the cabling trough under the floor) of the exchange office. The power cords run along the left-front of the chassis and out of the chassis either from the top or the raised floor depending on the equipment room conditions (DC power distribution cabinet, lightning protection box, and terminal block, etc.) of the exchange office.

Cable Management
