FWT-1550ES series,1550nm External Modulation Optical Transmitter,
CNR≥52dB, SBS: 13.16.18dBm adj,Plug-in type Dual Module Power Supply.
Product description
FWT-1550ES Externally Modulated Optical Transmitter adopts narrow line width,low noise and continuous wave DFB laser as light source and adopts low cost single-output LiNbO3 external modulator that is especially designed by JDSU to modulate signal,which reduce the cost of transmitter largely.Based on a series of characterized optimization and technical innovation,FWT-1550EC optic transmitter can reach excellent index with flatness ≤0.75dB in bandwidth of 47~862MHz,SBS:13.16.18dBm ,point to point>50Km,(0dBmReceiving)CSO≤-65dB,CTB≤-65dB,CNR≥52dB.The whole unit is equipped with perfect RS232 communication interface,SNMP network management,1+1 back-up power supply,and casing temperature auto-control.all the optical port for FWT-1550ES optic transmitter can be installed in the front panel(the back panel is also available if needed).
Product feature
1, High performance: no laser chirp,low dispersion distortion,high extinction ratio,with excellent characteristic within 40~862MHz in-band.
2, Narrow bandwidth(Typ.=1MHz),low noise and DFB continuous wave laser.
3,The operating bandwidth is up to 47~862MHz.
4,High index:unique innovation technology,offering excellent CNR,CTB and CSO.
5, SBS:13.16.18dBm,point to point>50Km optical transmission.
6, AGC/MGC mode is optional at spot,OMI can be optimized at spot.
7,Optional1+1 back-up power supply.
Main application
1, FWT-1550ES 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.
