Main application

1.   FWT-1550EC optic transmitter can be used in second-grade service area of sub-station,providing second-grade users with high quality and high reliability value added service such as RFTV,IPTV,VOD and so on with excellent P/P ratio .

2.   It can also avoid the limitation on  transmission bandwidth and distance as well as system CSO deterioration caused by laser chirp for adopting 1550nm direct modulated optical transmitter.
