SMF-155 Back Card

The SMF-155 back card provides a physical single-mode fiber optic SONET OC-3 interface that conforms to ANSI T1.105 and GR-253-CORE standards. This interface uses SC connectors, and redundant configurations are supported through Y-cables. For specifications on this card, refer to Appendix A, “Technical Specifications.” Note that Automatic Protection Switching (APS) requires the “B” model—an SMF-155/B.
