1310nm Optical Transmitter

I GENERAL DESCRIPTIONS
BEST-1310nm-OT-AUTO series laser transmitter, the main equipment to build Cable TV HFC network, is mainly used in transmitting the TV image signal, digital TV signal, TV voice signal, and digital signal (compressed signal) in a long distance. The equipment chooses the excellent DFB laser as light source and the frequency part adopts the perfect auto processing techniques and advanced pre-distortion circuit, with the perfect microprocessor auto monitored control system inside, to guarantee the optimized performance of transmitter.
II FEATURES AND ADVANTAGES OF BEST SERIES TRANSMITTER
1. Choose world-famous DFB laser imported with original package, with narrow spectrum line, good linearity, high output power.
2. The frequency drive circuit adopts the pluggable AGC circuit and auto processing drive level to keep the indexes of CSO, CTB and CNR in their optimum value and ensure the high performance of transmitter. It also can enhance the value of CNR greatly.
3. Pluggable multi frequency-point frequency pre-distortion technology combines with AaGas devices to improve CTB and CSO greatly and enhance the value of CNR greatly.
4. Perfect microprocessor auto monitored control circuit inside to monitor exactly the optical output power and status of laser to ensure the stable optical output power. And start time delay to extend the laserý­s working life.
5. With blue indicator on the front panel to exactly indicate all kinds of working status.
6. 19ý¯standard rack, RS485t and RS232 interface net-management interface to realize monitoring net management conveniently.
