Product Description
Externally Modulated CATV 1550nm Optical Transmitter


- Characteristic:
-
High performance: Externally modulated technology, no laser chirp, low dispersion distortion, high extinction ratio, with excellent characteristic within 40~862MHz.
-
1+1 powers supply back , up hot-plug function available.
-
Narrow bandwidth (0.65MHz), lower noise, DFB continuous wave laser, is propitious to reduce the influence of the dispersion.
-
The operating bandwidth is up to 47~1080MHz.
-
CNR ≥ 53dB and excellent CTB, CSO index.
-
SBS: 13~18dBm adjustable.
-
ITU standard wavelength, ±200GHz (±1.6nm) adjustable.
-
AGC/MGC mode is optional at spot. OMI can be optimized at spot.
-
Perfect RS232 communication interface.
-
Advanced SNMP network management function.
-
Casing temperature auto-control.
