1310nm optical transmitter is the important part of CATV HFC network. Its main function is fiber remote transmitting of TV image signal, digital TV signal, telephone audio signal and data or compressed data signal. This transmitter own excellent capability, the Light source is imported high performance DFB laser, and radio frequency driving part is adopted RF power numeral self-controlling technology and inset excellent micro-computer self-monitoring system.

Features:
◆ High performance DFB laser with international famous brand
◆ Adopting RF power numeral self-controlling technology on radio frequency driving part to make CSO,CTB and C/N on high-top and keep output level unchanged.
◆ Adopting advanced multi-point RF predistortion technology to improve parameter of CTB , CSO and C/N
◆ inset excellent micro-computer self-monitoring system
◆ VFD blue screen display in front board showing precise information of all equipment
◆ 19〞1U standard rack,RS232 and RS485 interface
