Crestron SFP-1G Transceiver Module for DM-NVX Series

DM-NVX endpoints with a fiber cage take one of these three 1 Gb optics, and which one is decided by the fiber already in the building. The SX is duplex multimode at 850 nm for in-building runs, the LX is duplex single-mode at 1310 nm for campus distances, and the BX-D is a bidirectional single-strand part at 1490/1310 nm for plants where only one fiber is available per endpoint.

The BX-D is the downlink half of a bidirectional pair and has to be matched with its uplink counterpart at the other end; the SX and LX parts are ordered in twos, one per end. Order one module per NVX endpoint plus one per matching switch port.
