32 Ports CATV WDM EDFA

When optical transmitting over long distance, the optical signal has to be amplified many times because of the signal loss from fiber attenuation, connectivity losses, fiber splicing losses, etc. Before optical amplifier is invented, the optical signal has to be first converted into electrical signal, amplified, and then converted back to optical signal again.

32 ports CATV WDM EDFA

EDFA, or Erbium-doped Fiber Amplifier, uses the Erbium-doped fiber as an optical amplification medium to directly enhance the signals. The amplifying medium is a glass optical fiber doped with erbium ions. The erbium-doped fiber gain medium amplifies light at wavelengths that are in the neighborhood of 1550 nm-the optical wavelengths that suffer minimum attenuation in optical fibers.

Wavelength Division Multiplexing (WDM: Wavelength Division Multiplexing) is a technology that simultaneously transmits multiple wavelength signals in an optical fiber. WDM technology increases the transmission capacity of an optical fiber several times to tens of times or even hundreds of times compared with single-wavelength transmission, thereby increasing the transmission capacity of the optical fiber, reducing costs, and having great application value and economic value.

PON+EDFA application EDFA optical amplifier mainly used for 1550nm, which make CATV over fiber tranmission more distance. The PON work with EDFA by FWDM, which realize triple FTTH application.
