4.4.5. Connecting the Optical Interfaces of SMUB

The SMUB of 3P@C 4450E supports the 100M/1000M uplink optical interface module and the ATM uplink optical interface module. The standard SC fiber connectors shown in Figure 4-42 are adopted for these optical interfaces.

Figure 4-42 SC optical connector

When connecting an optical interface, note that the fiber specifications must be consistent with the features of the uplink optical interface. For example, if the optical interface is a multi-mode interface, the multi-mode fiber should be used. And when the optical interface is a single-mode interface, the single-mode fiber should be used. Also you should make clear the transceiving polarity of the optical fiber interface. The 3P@C 4450E uses standard SC fiber connectors. During the optical interface connection, the fiber with SC connectors at both ends should be used. If one end of the fiber connects with the Rx-Tx interface of the uplink optical interface of the 3P@C 4450E switch, then the other end should be connected to the Tx-Rx optical interface of the peer equipment. That is, the Rx interface of the uplink optical interface corresponds to the Tx optical interface of the peer switch, while the Tx interface of the uplink optical interface corresponds to the Rx optical interface of the peer switch.

Figure 4-43 shows the connection of the uplink optical interface of 3P@C 4450E:
