OT1550 External Modulation Optical Transmitter
Summary

Main board in this transmitter afforded by U.S. E-0 Company and the transmitter passed assemble, test and aging by our company. Performance to price ratio is high and suitable for large or middle-size CATV fiber cable network.

Performance Characteristic
  • Adopt several international patents pre-distortion dealing technology to guarantee the fine non-linear index.
  • Adopt famous brand 1550 nm DFB laser instrument guarantee low noise, high power and high dependability.
  • Can initiate the mode SBS function, offer more elastic disposition.
  • Adopt Automatic Gain Control design, make different RF input level keep about equal output performance still, Simplify installing and operation sequence.
  • The built-in microprocessor offers fine control performance and state to show that is controlled.
  • RS485 controls the interface to control by carrying on the remote state.
  • 19" 1U high-standard framework type installation.
