    FWT-1550ES series 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-1550ES series Externally Modulated Optical  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 Series Externally Modulated Optical  can be installed in the front panel(the back panel is also available if needed).

     


     

     High performance: no laser chirp,low dispersion distortion,high extinction ratio,with excellent characteristic within 40~862MHz in-band.

     Narrow bandwidth(Typ.=1MHz),low noise and DFB continuous wave laser.

    The operating bandwidth is up to 47~862MHz.

     High index:unique innovation technology,offering excellent CNR,CTB and CSO.

     SBS:13、16、18dBm,point to point>50Km optical transmission.

     AGC/MGC mode is optional at spot,OMI can be optimized at spot.

     Optional1+1 back-up power supply.
