Direct Modulation Optical Transmitter OT1550D1-xx

1550nmDirect Mode Laser Transmitter of OT1550D1 series mainly used in overlayInsertion System adopts 1550nm Direct Laser only used in Dense WavelengthDivision Multiplexing (DWDM) system. Its output optical wavelength is as longas standard ITU wavelength. RF Pre-distortion Circuit developed and operated byus is used in the part of Therefore Driver. Built-in sound MicrocomputerAutomatic Control System is built in it to ensure the excellent performance

Feature:

◇ Use the internationalfamous brand high performance DFB laser with narrow spectrum, good inearity and high outputpower.

◇ RF drive adopting RF powerdigital automatic process technique, can according to level of input RF signal and numberof channels (15-84channels), automatically processing drive level power, making the C/N,CTB and CSO always in best worth, insure product function;and be steady of outputlevel.

◇ Advance multi-frequency RFpre-distortion technique with arsenide kalium component availably improves CTB andCSO, the most important parameter of CATV, and heightens C/N at the same time.

◇Built-in perfectmicroprocessor automatic monitor circuit can real-time accurately monitor optical output power and temperature of the laser insure stable optical output power, and prolongs work life of thelaser availably.

◇Built-in blue VFD monitor onfront panel can accurately display the equipment's each work status parameter.

◇19″1U height standard rackmount, equipped standard IEEE802.3 10Base-T Ethernet network port and RS232network port, can expediently realizes monitor through network.

◇Support GB/T 20030-2005HFC Network control management
