3C16858 (JE821A) 3Com 7700 8-port 1000BASE-X Module – 8 x GBIC
HP 8 Port 1000Base-X 7700 Module (JE821A)
3Com Switch 7700 – Switch – Gigabit EN + 8 x GBIC (empty) – plug-in module. This module delivers eight ports of high-performance Gigabit Ethernet switching with optional Gigabit interface converters (GBIC) for both fiber and copper connections. 3Com Switch 7700 modules support on-board or local Layer 2 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 help enable applications to run faster across the network. The reduction in latencies will help improve the quality of video and voice traffic across the network.
