1310nm Optical Transmitter With 1* 2mw Output

1310nm optical transmitter with 1* 2mW output General features
1. Imported highly linear DFB laser of low noise, big transmission capability and small nonlinear distortion.
2. Built-in APC and ATC circuits to ensure stable optical output power and operating temperature, and make the CSO, CTB and C/N indexes kept in the optimum state all the time
3. A GaAs element is adopted as the preamplifier, which not only lowers the input level and adds a radio frequency predistortion circuit, but also enhances the CSO, CTB and C/N indexes.
4. Microcomputer-based real time controlling and monitoring
5. The unit is supplied with standard RS-232 and RS-485 interfaces, which can be used for network management and remote monitor.
6. Perfect safeguarding circuit: For power on safeguard, over excitation safeguard, lightning strike safeguard, and so on
