Requirements for optical amplifiers in optical fiber communication systems

(1) High gain; (2) Wide working range and flat gain; (3) High saturation output optical power; (4) Low insertion loss; (5) Low noise figure; (6) The working characteristics are stable, preferably independent of temperature and polarization state; (7) Small size, light weight, low power consumption and long working life.

New Product - 52EYA

Combined with the development trend of the optical fiber transmission industry and a large number of market research, WSEE officially launched the 52 series of new EYDFA after the 50 series of EYDFA. This series of products have been put into production and officially sold in December.

The Important Role of Optical Fiber Amplifiers

Optical amplifiers have promoted the application of optical wavelength division multiplexing technology. The outstanding problem originally encountered by wavelength division multiplexing technology is that each relay station must separate multiple wavelength signals, separately perform photoelectric optical conversion, and then relay optical......
