Optical amplifier ARCOTEL WE1550

3

 

Purpose:

WE1550-хх - optical amplifier on the erbium-doped fiber (EDFA - Erbium-Doped Fiber Amplifier). The optical amplifier consist of erbium-doped optical fiber and high-reliable pumping lasers working at 980/1480 nm. Good operational data and acceptable cost allow to use this model in the cable television networks of large and medium sizes.

Benefits:

  • Low-noise and high energy efficiency is provided by applying the pumping laser system with different wave length;
  • The microprocessor control system provides stability of parameters and working modes;
  • Embedded display for control of working modes;
  • Wide range of available output powers (different models);
  • Independent built-in supply unit;
  • Standard constructive 19" 1u
