Cabling a Fiber
Optic Port
When attaching a fiber optic cable, be sure to observe the following
guidelines:
ˆ Be sure that the cable connector is firmly locked into place in the port.
ˆ You should verify that you are using the appropriate type of fiber optic
cabling.
ˆ You should verify that the operating specifications of the converter’s
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.
ˆ Dual SC and ST ports consist of two separate connectors, as shown in
Figure 25. 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 or ST 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.
