The SFP-8G31-10-xx series single mode transceiver is small form factor pluggable module for serial optical data communications such as X1/X2/X4/X8 Fiber Channel. It is programmed for installations in switches, routers, servers, PCI Cards, Firewalls and other connections in equipment that have 8G SFP+. Single-fiber bidirectional (BIDI) optical modules must be used in pairs. For example, SFP-10G-BXD1 must be used with SFP-10G-BXU1. 8G with a wavelength of 1310nm, suitable for distances up to 1. Additionally, the module features digital optical monitoring (DOM) capabilities that allow. Brocade Compatible 8G Fibre Channel SFP+ Transceiver Module (SMF, 1310nm, 20km, LC, DOM) The Brocade compatible module provides 8GBase-LR throughput up to 20km over single-mode fiber (SMF) using a wavelength of 1310nm via an LC duplex connector.
