Performance Analysis of Erbium-Doped Fiber Amplifier in Fiber Optic Communication Technique

Optical fiber communication is the best for transmitting data at a high rate, we are trying to push the data rate even higher. While the fiber channel may be capable of transmitting terabit-per-second data rates, no existing single communication system can make complete use of this speed. Adding more and more fibers to the system as a method of increasing speed is uneconomical as we know the global network is made of a large submarine cable networks that is expensive to modify. Erbium-doped fiber amplifiers are the by far most important fiber amplifier in the context of longrange optical fiber communications they can efficiently amplify light in the 1.5-μm wavelength region. The invention of Erbium-doped fiber amplifiers (EDFA) with large bandwidth is largely responsible for popularizing this technique. In terms of multi-wavelength signals, so long as the EDFA has enough pump energy available to it, it can amplify as many optical signals as can be multiplexed into its amplification band.
