Economical 1550nm External Modulated Optical Laser Transmitter EOT55XXE
  • Summary
  • Features
  • Advantage
    EOT55XXE is a model of 1550nm externally modulated optical transmitter which adopts narrow line width, low noise, and continuous wave DFB laser. Adopting LiNbo3 external modulator that is expecially designed by JSDU, EOT55XXE external modulated optical laser transmitter can reach high index of CNR =51dB, CTB= -65dB, CSO= -65dB, SBS 13~18 dBm adjustable. The whole unit is equipped with SNMP network management, 1+1 plug-in back-up power supply.
