FEATURES
High quality Silicon optical receiver module embedded with IC amplifier.
1290~1580nm optical wavelength, -9~+2dB allowable optical input power.
AGC working mode or MGC working. A switch is embedded.
Built with AGC circuit to sense optical input power and keep output RF level constant (under AGC mode).
Built with unique Attenuation Control Board to tune forward-path RF level (under MGC mode).
GaAs power doubler amplifier module enlarges RF level.
2 RF outputs, level ≥ 104dBμ V when optical input power as -1dBm.
Forward-path RF slope is regulated by plug-in fixed value equalizer, and level could be tuned down with plug-in fixed value attenuator.
Bidirectional design. Return-path is optional.
Duplex filters 30/47MHz, 42/54MHz, and 65/87MHz optional.
Optical power measuring point is built for both forward-path and return-path.
Tri-Color LED at optical input indicates optical power status.
RF Test Point is built for both forward-path and return-path.
Independent power supply port. RF output ports could feed power into coaxial cables.
Waterproof metal die-casting housing.
Suitable for strand mounting.
