externally modulated 1550nm optical transmitter

       FEATURES

1)No laser chirp, low dispersion distortion, high extinction ratio

5)        Machine case temperature control automatically

2)         Original system optimized control technology, offers excellent CNR, CTB, CSO & SBS index

6)        High quality: intuitionist Optic Modulation Identity (OMI) display

3)         Flexibility: Original SBS critical value 13, 16, 18 adjustable at spot, it can fit for different network, OMI adjustable optimized at spot, AGC mode is optional at spot

7)        Advanced network management function( each unit has separate IP address)

4)        Reliability: build-in double power supplies, switch automatically.
