Chapter 2: Installation

Cabling a Fiber

Optic Port

When attaching a fiber optic cable, be sure to observe the following

guidelines:

 Be sure that the cable connector is firmly locked into place in the port.

 You should verify that you are using the appropriate type of fiber optic

cabling.

 You should verify that the operating specifications of the fiber optic port

are compatible with the fiber optic port on the remote end-node. For

example, you cannot connect a fiber optic port with a maximum

distance of 500 meters (1,640 feet) and an operating wavelength of

1310 nm to another fiber optic port that has a maximum distance of 20

kilometers (12.4 miles) and an operating wavelength of 1550 nm.

 Dual SC port, shown in Figure 13, consists of two separate

connectors. Each connects to a separate fiber strand. One is for

receiving data and the other is for transmitting data. When connecting

a fiber optic cable to a SC port, be sure that the receiver fiber

connector is connected to the transmitter connector on the remote

end-node, and the transmitter fiber connector is connected to the

receiver connector on the remote node.

Caution

Make sure to measure the optical power prior to connecting the

cables. High optical power can potentially damage the optical

receiver.
