Description
Overview
1550Pxx series indoor 1550nm optical transmitter adopts famous brand high linearity DFB laser, and build-in perfect pre-distortion adjustment circuit. Owning the internal micro-processor auto monitor system, the transmitter would ensure excellent performance.
Main features
- High performance DFB laser.
- Excellent pre-distortion circuit to improve C/CTB and C/CSO
- AGC RF control circuit can ensure the constancy of laser’s modulation depth.
- ATC and APC can ensure the best operating status of laser.
- Slow start-up circuit and RF over-protection circuit ensure the laser will not be damaged.
- Perfect microprocessor automatic monitoring circuitry can monitor the operating status real-timely and precisely
- Front panel display status and alarm.
- With RJ-45 and RJ-232 interface, remote control conveniently.
