Long-distance Gigabit Ethernet connectivity: The Gigabit-LX specification allows a distance of up to 5km on 9 micron single-mode fiber, and up to 550 meters on 62.5 micron or 50 micron multimode fiber. Port is auto-enabled - ready to operate as soon as it is installed Auto-configuration: a default configuration that works well for most networks. Adheres and conforms to the IEEE 802.3z standard for Gigabit connectivity Link and Mode LED's for every port provide information on link status, network activity, connection bandwidth, and communication mode (half or full duplex).
