16 Port CATV WDM EDFA Amplifier

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.

16 port CATV WDM EDFA Amplifier

When optical transmission over a 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 the optical amplifier was invented, the optical signal had to be first converted into an electrical signal, amplified, and then converted back to an optical signal again. The process is very complicated and expensive. EDFA Optical amplifier can amplify signals directly, this process is significantly cheaper and started a fiber optic revolution.

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.
