Outdoor Bi-dictional Four Outputs Optical Receiver

outdoor optical receiver with 4 outputs, waterproof.Excellent optical AGC control technique, high gain, low distortion.

INFORMATION

Overview

The optical receiver is an outdoor 4 outputs waterproofing receiver. It is mainly used in the building, community or village with concentrated users and high level multi-outputs distribution network. Also suitable to used in the place where it is not convenient to take the electricity and single equipment drives many users. It can work together with ONU or EOC to realize the network convergence. This machine adopt GaAs for amplification at the front stage and GaAs power double amplifier module in the back stage. Adjustable ATT and EQ is convenient for debug.It is the ideal model of the construction of CATV network.

Characteristics

u High responsivity PIN photoelectric swith tube.

u Precision detection circuit can real-time display the output power through LED lamp or digital tube accurately.

u Optimize the circuit design,SMT+module amplifier classic circuit photoelectricity signal transmission is more fluency.

u Power double output, high gain, low distortion, compact structure, convenient installation, is the first choice equipment of FTTB CATV network.

u Excellent optical AGC control technique, when the input optical power range is -7~＋2dBm, the output level, CTB and CSO basically unchanged.

Note: Configure 59 PAL-D analog channel signals at the 550MHz frequency range. Transmit digital signal at the frequency range of 550MHz～862MHz. The digital signal level (in 8 MHz bandwidth) is 10dB lower than analog signal carrier level. When the input optical power of the optical receiver is -2dBm, the output level: 108dBμV, test the CN,CTB and CSO.
