SFP module D-Link DEM-311GT

D-Link DEM-311GT 1000BASE-SX SFP Transceiver

The D-Link DEM-311GT is a 1000BASE-SX SFP (mini-GBIC) optical transceiver that plugs into an SFP slot on a switch and provides a Gigabit Ethernet link over multi-mode fibre. It works at 850nm, uses a duplex LC connector and reaches up to 220 metres on 62.5 micron fibre and up to 550 metres on 50 micron fibre.

It suits switch-to-switch links inside a building, connections between floors and fast transfers between wiring closets. The metal housing reduces EMI and adds durability, and the module is hot-pluggable, so the switch does not need to be powered down.

Key features

• Gigabit over multi-mode fibre - 1000BASE-SX at 850nm provides a full-duplex Gigabit link over 50 or 62.5 micron fibre.
• Up to 550 metres - Up to 220 m on 62.5/125 micron fibre and up to 550 m on 50/125 micron fibre, enough for most in-building links.
• Hot-pluggable - Insert or replace the module while the switch is running, with no reboot and no network downtime.
• Metal housing - The metal enclosure reduces electromagnetic interference and protects the module in everyday use.
• MSA standard - Standard SFP form factor per the MSA agreement and IEEE 802.3z, with Class 1 laser safety approvals.
