Zhejiang BC&TV Technology Co., Ltd.Zhejiang BC&TV Technology Co., Ltd.
ZBL5061RB series dual fiber bidirectional optical receiver, integrated a forward optical receiving unit and return transmitting unit. The forward path adopts photoelectric conversion device with high performance and multistage amplifier circuit. The final stage adopts imported GaAs power multiplication module, with terrific optical link index. In the return transmitting link, we adopt patent technology of RFoG that designed independently by ourselves. We design the function of automatic transmitting optical power control (AOC), which reduce convergent noise of return system and the power consumption, and prolong the working life. The machine is equipped input and output optical power display, forward optical AGC control, adjustable attenuation and equilibrium. Suitable for 1 GHZ bidirectional HFC network of cable TV, is preferred products for bidirectional HFC network of cable TV upgrade of the large, medium and small cities and towns.
