optical fiber cable. Figure 3-94 shows the cable specifications, which are the same as those for the OC-3c/STM-1 (POS) MMF interface (Subsection 3.10.2.6). One or more cables of the same type is recommended to be prepared for spare.

The boundary with ATM (OC3) is used as a connector on this router’s side.

A multimode optical fiber is used for connection with the router. Figure 3-101 shows the schematic diagram. This router’s optical interface specifications are shown in Table 3-107.
