Products Description
This FTTB AGC CATV Optical Receiver is designed as a low power optical receiving device for adapting "Fiber To The Building" (FTTB). This device adopts high sensitive optical photo-tube, low noise gallium arsenide amplifier chip in preposition and gallium arsenide push-pull amplifier circuit in last stage which provides maximum output level over 2×100dBuV. Additionally, high-precision lightning-protection anti-surge linear power supply, AGC automatic output level control and digital display of optical receiving and RF output level are configured in this device. Due to the superior performance of main material and well-designed circuit, it guarantees the performance index and better reliability of this complete device.
Performance characteristics
Greater than 0.9A/ W high responsiveness PIN photoelectric conversion tube.
Line optimization design, SMT process production,optimize the whole signal channel, photoelectric signal transmission more smoothly.
GaAs amplifier parts, power multiplier output, high gain, low distortion.
Receive optical power range -12~ +3dBm ,
Excellent AGC characteristics, the Input optical power-8 -+2dBm,the output level remains unchanged, CTB,CS0 basically unchanged.
Configured with national standard network management transponder, can easily access the network management system.Configured with national standard network management transponder,can easily access the network management system.
