Outdoor Type Optical Relay Station, it is suitable for 1310nm relay transmission or front end second transmission of the optical fiber communication system, after receiving the 1310nm or1550nm optical signal. it also extends the optical fiber communication distance of the imitation or digital system . Relay transmission adopts the original import DFB Laser (ORTEL, FUJITSU, AOI etc.) . Meanwhile this device sets up the separate RF input threshold , which has the local input function and also can form the Outdoor Optical Transmitter by itself. This unit is especially designed for the extension of coaxial network. It is small size outdoor fiber optical mini relay station.It can work as both node and small transmitter to expend 1~ 4 opical node.
