3C17513 (JE910A) 3Com Switch 8800 12 Port 1000Base-X Module (SFP).
HP 12 Port 1000Base-X 8800 Module (JE910A)
This module delivers twelve ports of high-performance Gigabit Ethernet switching with optional Small Form-Factor Plug-in (SFP) ports for both fiber and copper connections. Switch 8800 modules support on-board or local Layers 2/3/4 switching, allowing packets to remain local to the module, which reduces backplane and switch fabric loading. This reduces congestion in the network minimizing packet loss, to enable applications to run faster across the network. The reduction in latencies will improve the quality of video and voice traffic across the network
