| Description
OPR-1008SD optical receivers is with high performances and high reliability, 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 -6dBm~+2dBm in circuit.They are suitable for HFC transmission network.
Features
1) RF output level is employed optical Automatic Gain Control (AGC), any optical node in one optical network, if only the optical power range is within -6dBm~+2dBm, we don’t need adjust the attenuation value of the attenuator of this machine, we can ensure the output level of the whole machine remain the same, and CTB & CSO are remained unchanged, it is easy for debugging the project.
2) Operation platform designed is xx~1000MHz.
3) Electric adjustable attenuator and electric adjustable equalizer, it is convenient to debugging and usage.
4) Low-noise amplifier matching circuit and amplifier module with excellent output ensure the CTB and CSO of the output signals comply with national standards.
5) This device adopts SCM to control, which enables direct display of +8Vsupply voltage, RF output level, input optical power, attenuation and equalization of the optical receiver, and both manual and remote control of the setting of attenuation and equalization. 6) AC 220V switch power supply.
