External 1550nm Optical Transmitter 2*11dB

It is new generation of external modulated 1550nm Optical Transmitter from Uvins Technology. By adopting orginal band-new laser and external modulators from USA and Japan to Guarantee its good and stable performance during CATV and Digitla TV signal transmission over fiber network. this model is our high-end type, with pre-distortion circuit design to ensure its technical parameters can meetCNR≥53dB,CTB≥65dBand CSO≥65dB., SBS 13-19dBm Adjustable for options during network setting..
With its stable performance and high technical parameters, this transmitter canbe working with very good picture qualitystarting from 47Mhz-1000Mhzfor long distancetransmission for CATV and Digital TVnetwork, and good choice for TV operators who want tosolve the problems ofpoor picture quality in low frequency(47Mhz-200Mhz) signal transmission.
SNMP available for monitoring from PC.
Technical Features:
* Adopting Original brand new Laser and external modulator from USA and Japan.
* With perfect pre-distortion circuit design to guarantee CTB,CSO and CNR working in high technical paramters.
*SBS from 13dBm-19dBm adjustable(Step 0.1dBm.) to meet the needs of network setting.
