Parameters

1310nm Forward Path Optical Transmitter is mainly used in the headend and sub-headend equipment rooms of the HFC networks. It convert RF signals into optical signals, and cover optical nodes or receivers over a large area.

Using low-noise high-quality DFB laser as the light source, with built-in professional APC/ATC control circuit, the performance is stable.
Built in pre distortion circuit design, with excellent CNR, CTB, and CSO index values.
AGC/MGC control can maintain output performance at different RF input levels.

●selects high performance DFB laser, equipped with ATC/APC circuit, the index is excellent, the output power is stable.

●advanced pre distortion technology and RF AGC/MGC circuit, effectively improve the optical nonlinear index, in the AGC

range of RF input to ensure the stability of the laser modulation system.

●optical transmitter module is equipped with two RF input port, port using amplified circuit active isolation, with excellent

RF isolation index, convenient for the user to broadcast service and local business spots of mixed input.

●light module is equipped with digital signal compensation function, the user can make compensation settings on the

menu, in order to ensure that the digital channel can increase the time module can always be in the AGC state.

●through the platform optical liquid crystal display to monitor optical power, bias current and the temperature of the

laser, the refrigeration current, laser excitation level, AGC/MGC control volume and various voltage parameters.
