Reverse light emitting module of HFC network optical workstation with good transmission performance

The utility model relates to a reverse light emitting module of an HFC network optical workstation with good transmission performance, which comprises a laser module, a dual operational amplifier module and a modulation module which are mutually coupled to form a reverse laser operation loop of the optical workstation. A positive input pin of the dual operational amplifier module is coupled with an adjusting resistor, the adjusting resistor is connected in parallel with a fixed resistor, the laser module is coupled with a DFB laser, and the dual operational amplifier module comprises dual operational amplifiers which are mutually coupled; the fixed resistor is connected in parallel with a current adjusting resistor, and the optical workstation operation loop is also coupled with an indicating lamp module; the FP laser in an original optical workstation is replaced by the DFB laser, reverse signals of a cable television HFC network are transmitted more efficiently, the resistance is adjusted to avoid circuit o
