» Technical Specs

GTW-OR8204 Four Ways Outdoor Optical Receiver integrates forward optical signal receiving, distribute and reverse transmitter, which is an economical, high performance and high gain device.
It is mainly used in the end of optical fiber network, where needs multi-ways high RF output level distribute to subscribe directly, and request bi-directional function. In this way it could reduce the amplifier and make the network more reliable.
The rack adopts the newest waterproof aluminum rack with the most popular aluminum passivation technology. About inside circuit, after the obverse optical signals transform, the forward RF adopts low noise GaAs amplify, even though the optical power is very low, it still can guarantee the whole machine’s carrier index.
In order to get the higher non-linearity index, we use the power double module in the end. LED indicator light on the panel displays the forward optical receiving power.
