12-Port 1000BASE-X SFP Module
Overview
The DES-6509 is a 12-port SFP Module for the D-Link® DES6500 chassis. It uses standards-based 802.3z Gigabit SFP 
transceivers to meet the demands of today’s enterprise and 
service provider networking infrastructure. The DES-6509 
is the perfect solution for uplinking to servers, storage, or 
department level switches such as D-Link xStack 
DXS-3200. Fiber media is a great solution because it allows

for increased distances over copper cabling. When used with 
D-Link DEM-310GT SFP ber transceiver, a total distance of 
up to 6.2 mi (10km) can be reached, which is often necessary 
when running across larger distances such as campuses 
or multi-building environments. If your situation consists of 
shorter distances, the DEM-311GT transceiver from D-Link 
provides Gigabit Multimode connection at distances of up to 
1800 ft (550 m).
