11mw Standard 1550nm Direct Modulated optical transmitter with AGC

1550nm intelligent directly modulated optical transmitter, mainly used in 1550nm optical fiber transmission system is the most important equipment to construct the CATV network. It mainly used for the value-added services of TV image signal, digital television signal, telephone voice signal and data (or compressed data) signal. By built-in WDM, multiplex the inter-cut optical signal and the main optical signal then output. After setting required optical difference, the perfect adjustable optical attenuation function can automatically control the inserted optical signal according to the main optical signal, realize inter-cut system full automatic adjustment. Provide high quality low cost solution for all-optical relay 1550 optical fiber CATV system, and local value-added services inter-cut.

Features

  • Low noise high linearity Ortel-Emcore cooled DFB laser
  • RF power digital automatic process technology control the laser driving RF power lever automatically according to RF signal level and channels, ensuring the best C/N, CTB and CSO
  • Excellent pre-distortion technology improves CTB,CSO and C/N
  • Built-in microprocessor accurately monitors laser output power and temperature
  • Front panel VFD displays the status parameters and function message
  • SNMP network management optional
  • OEM is optional

  • Applications

    1. 1550nm Optical fiber transmission system
    2. Construct the CATV network
    3. Local value-added services inter-cut
