Company Information

 

  

 

 

 
Product Description

  

 

CT3155B Directly Modulated Optical Transmitter is specially designed for Overlay slot system. It has the ability of supporting up to 32 IPQAM frequency point spots. As the first company to introduce Overlay frequency point spot system, C-Data optimizes performance and structure of spot transmitter by large number of project experience and system debugging experience, focusing application of spot system. And finally, we greatly increase performance of spot system.

 

Unique electric-control optical attenuation function guarantees optical difference of spot system can be automatically controlled as it is set by automatically controlling spot optical signal based on broadcast signal value after setting optical difference of spot system. This function can realize automatic adjustment in the whole course of spot system. So this design is humanized and easy to operate.

Meanwhile, special AGC circuit with electric-control attenuator as core can realize automatic control of modulation and flexible control of drive level value. And it can guarantee stability of electrical level after system debugging, and greatly simplify project debugging.

Functional Features

  • Optimized integrated design of pre-distortion, amplifier and laser
  • Integrated electrical control of Overlay spot function, can be spot debugging set by LDC or NM control
  • Innovative operation function of AGC and MGC, working separately at the same time, make the product easy to use and improves the applicability of the system.
  • AGC has a function which can be set to “ON” or “OFF”.
  • Spot machine with Overlay has the function of automatic shutting down spot when main line power is low.
  • New-type and stable laser bias and temperature control
  • ITU wavelength DFB laser
  • Bandwidth can be up to 1GHz
  • By adopting low-consumption design, complete machine power consumption < 10W, reliability of equipment is greatly increased.
  • Double-power, hot-plug, balance load operation, light power load, seamless switching when it fails, greatly increase life time.
  • By equipped SNMP network management function, it has the function of remote network management and local monitoring.
  • LCD operation status: optical power, bias current, laser temperature, refrigeration current and spot setting status, etc.
