OC3, Line Modules (SMF, SMFLR, & MMF)
The Line Modules for the OC3 BNI cards are back cards used to provide a physical interface to the
transmission facility. There are three types, a single-mode fiber intermediate range, single-mode
fiber long range, and a multi-mode fiber backcard. The Line Modules connect to the BNI through
the StrataBus midplane.
For connector information, refer to Figure 4-8 and Table 4-6 for the LM-OC3-SMF and to
Figure 4-9 and Table 4-7 for the LM-OC3-MMF. The LM-OC3-SMFLR uses the same type of
connectors as the LM-OC3-SMF.
