Offering flexibility

With all kinds of 10/100/1000Mbps Ethernet Media on RJ-45 port and performing highly stable Gigabit fiber capability, the PLANET Gigabit media converter series GT-80X (GT-802, GT-802S, GT-805A and GT-806A/B) supports conversion between 10/100/1000Base-T and 1000Base-LX/SX network. The GT-80X series offer three types of connector, SC / SFP / WDM connector, with single-mode or multi-mode media as required so that an Gigabit fiber network can be efficiently constructed through the Ethernet.

Designed in compact size, the GT-80X can be used as a standalone unit or being installed in the media converter chassis such as the PLANET MC-700/MC-1000R/MC-1500 ( 7/10/15-slot Media Converter Chassis to build a centralized fiber-optic network. The media chassis can feed GT-80X power to maintain the fiber-optic network at one location.

As the GT-80X series fully complies with IEEE 802.3 10Base-T, IEEE 802.3u 100Base-TX, IEEE 802.3ab 1000Base-T and IEEE 802.3z 1000Base-LX/SX, the installation of the Gigabit media conversion is quite quick and easy by simple plug and play. The GT-80x also supports flow control and back pressure in half-duplex to eliminate packets loss. Even when the web UI is not available, the network manager still can remotely control and monitor GT-80X by OAM (TS-1000 and IEEE 802.3ah) terminal function such as remote failure indication, loop back test, port status and performance monitoring and troubleshooting. 


Fiber-Optic Networking for ISP, Enterprise, and Home
With high performance of data transmission and easy installation, the GT-80x can build the network solution of FTTH (Fiber to the Home) or FTTC (Fiber to the Curb) for ISPs and FTTB (Fiber to the Building) for small office network environment of enterprises.
