Two-wavelength WDM-multiplexer
Print

1

Description:

Two-wavelength WDM-multiplexer is used for separating and combining optical signals (1310 and 1550). In other words, it can perform two types of functions: add optical signals with each other, so two optical signals are transmitted over a single fiber; select an optical signal from the mixed optical signals transmitted over a single fiber.

Advantages:

  • Small insertion loss;
  • Good insulation;
  • Good orientation;
  • Low level of PDL;
  • Good stability.

Areas of use:

  • Fiber-optic communication systems;
  • Fiber optic data transmission systems;
  • Fiber-optic network CATV;
  • Fiber optic test equipment;
  • Fiber optic sensors;
