FTTH Optical Receiver (Build-in filter)
ZHR28 series indoor optical node is a high performance and high reliability optical receiver. It is adopted optical detectors of a wide dynamic range, realizing automatic control (AGC) function of the RF output level of optical power input signals in a wide dynamic range as -8dBm~+2dBm in circuit.
Features
1.Operation bandwidth is 87~1000MHz.
2.One-way low noise RF signal output, it is economical and practical.
3.It has indicators for power supply and optical power.
4.Optical Auto Gain Control (AGC) function.
