1000Base-SX SFP for 3Com Switches

This HP-branded 3CSFP91 transceiver adds a single Gigabit Ethernet port over multi-mode fibre to compatible 3Com switches. It uses an LC connector and follows the 1000Base-SX standard for short-range data networking.

Suitable for Extending Listed 3Com Models

Network administrators upgrading a 3Com 4070, 7700 module, SuperStack 3 3870, 3848, 3824, 3812, 3226 or 3250, or a Baseline 2226 or 2250 can use this module. It is not for switches outside the listed compatibility list or for single-mode fibre links.

LC Multi-Mode Connector Decides Fit

The transceiver presents one LC 1000Base-SX interface that only works with multi-mode optical fibre. If the target switch port requires a different connector type or single-mode operation, this part will not function.
