Available Options

Our Gigabit Ethernet media converters comply with IEEE 802.3/ab Gigabit Ethernet standard, support two types of media for network connection such as 10/100/1000Base-T to 1000 Base SX/LX/ZX and connect these two types of segments to operate smoothly.

The media converters can be used in 16 slot chassis as plug-in modules. They can transform 1000Base-T (Copper Gigabit) media to 1000Base-SX/LX/ZX (Fiber Gigabit) media and vice versa.

The 1000Base-T port supports full-duplex Gigabit connection at wire speed with RJ45 connector, the fiber Gigabit connection supports shortwave (SX) or long wave (LX) laser optic with multi-mode or single-mode SC/FC/ST type connector.

This converters will give your Copper Gigabit connection the ability of interface with a fiber connection over a distance up to 80km.

10/100/1000 means that the media converters can convert the electrical signal of a 10/100/1000 Ethernet signal from copper to fiber. This solution will offer a low-cost integration option for network managers who want to migrate from 10/100 networks to Gigabit Ethernet. Gigabit only switches can now be connected to 10/100 networks without the need to upgrade the 10/100 side.

1, Extend the network distance between two twisted pair Gigabit Switches

Two Gigabit Ethernet Media Converters can extend the distance between 1000Base-T Switches across a fiber link up to 80Km in length.

2, Extend the network distance between a Gigabit Switch and a Gigabit File Server

Two Gigabit Ethernet Media Converters can extend the distance between a 1000Base-T Switch and a Gigabit File Server across a fiber link up to 80Km in length.

3, Extend Gigabit to 550m over 62.5 micron Multimode Fiber

Gigabit across 62.5 micron MMF cable is normally limited to 275 meters. By adding mode-conditioning adapters and 1000baseLX media converters you can extend the distance up to 550 meters on MMF cable plant.

4, Installing Gigabit 1000Base-LX routers and switches into existing multimode cable plants

Using mode-conditioning adapters and a 1000Base-LX media converter, connect a copper based Gigabit Switch with a remote 1000base-LX switch/router over existing multimode cable plant.

5, Connect 10/100 devices to Gigabit Backbone

Devices on a 10/100 ethernet switch can be connected to a Gigabit backbone through the use of rate converting 10/100/1000 Media Converters.
