What is an optical amplifier?

  An optical amplifier is a device that amplifies an optical signal directly, without the need to first convert it to an electrical signal. An optical amplifier may be thought of as a laser without an optical cavity, or one in which feedback from the cavity is suppressed. Optical amplifiers are important in optical communication and laser physics.

  There are several different physical mechanisms that can be used to amplify a light signal, which correspond to the major types of optical amplifiers. In doped fibre amplifiers and bulk lasers, stimulated emission in the amplifier’s gain medium causes amplification of incoming light. In semiconductor optical amplifiers (SOAs), electron-hole recombination occurs. In Raman amplifiers, Raman scattering of incoming light with phonons in the lattice of the gain medium produces photons coherent with the incoming photons. Parametric amplifiers use parametric amplification.

FOT PON Optical Amplifier products

  FOT PON optical amplifier series can be compatible with main FTTx PON Technology. It offers flexible and low-cost solution for triple play network integration and FTTH (Fiber to the Home).

  The advantages of FTTx Optical Amplifier (also called EDFA) series is a low noise, high performance, FTTP high power, multi-ports optical amplifier with gain spectrum band within 1540~1563nm. Each output port for optical amplifier has built-in well-performed CWDM. Every external up-link optical port of optical amplifier can connect with OLT PON port very conveniently. Each 1550nm (CATV)’s output optical port multiplex 1310/1490n’s data stream, in order to reduce the quantity of the component and improve the index and reliability of the system.

  FTTx PON Optical Amplifier has extremely low noise figure, the entire unit adopts twin-stage amplification, and the pre-amplifier adopts low noise EDFA, output cascade adopts high power EYDFA. When input optical power Pin=0dBm, the noise figure of unit is: Typ ≤4.5dB, Max ≤5.0dB Unlike other kind of product which need high optical power input to maintain lower noise figure.
  FOT EDFA, optical amplifier adopts the world’s top class pump laser and active optical fiber. Perfect APC, ACC and ATC control, excellent design in the ventilation and heat-dissipation ensure the long life and high reliable work of pump laser. RS232 and RJ45 offer serial commutation and SNMP network management port.
