2 Output CATV AGC FTTH 1310nm optical transmitter With Butterfly Laser
Product Overview
There are two RF input interface to input signal.. As the data input interface or local RF input interface, auxiliary input interface is decreased by 10dB,when the signal is input. After mixing signal is reduced by wave filter, only 47MHz is remained. And the mixed signal enters into the two levels of RF enlargement circuit including AGC and MGC. This transmitter mainly has 4 function modules: RF processing unit, laser DBF, control and warning protection circuit and power module. The motherboard module includes RF processing unit, laser DBF, and CPU controlling part is in the motherboard.
Double heating swappable power module provide this machine with +24v, +5v and –5direct current. Among these, the working voltage of RF module is +24v., heating voltage of laser is +5v. The bias voltage and cooling voltage of the laser is –5V. The users could subscribe the different input voltage form (like-48v)of power module as copy.RS232 computer interface is used for the local supervision. Dual 485 industrial standard interface can be used for long-distance network management and supervision.
AGC is used for output level of stabilizing enlargement circuit, making laser work in a stable OMT.(optical modulation index) MGC is used for manual adjustment of RF level to change OMT. The shift between AGC and the range of MGC and MGC could adjust on the front panel. The level fluctuation of input signal could be compensated by AGC automatically, but MGC needs compensating manually.
After the signal is enlarged, it enters in pre-distortional compensation circuit to compensate DFB laser’s non-linear distortion. After it matches with the network, it stimulates laser to engage in optical and electric shift.DBF laser is control by CPU through APC, bias current control and drive level to guarantee laser’s optimum working point. CPU changes APC’s bias current to realize the constant power output through detector in the laser. When the level or bias current are too high, RF switch will be off automatically, so as to protect laser.The display and warning of the status has two forms: LED and LCD .LED indicates key moving status., and LCD indicates the concrete key working parameter and status.
