PA Preamplifier Card Erbium Doped Fiber Amplifier 1550nm with OEM/ODM Service
EDFA series optical amplifiers are erbium-doped fiber amplifier products launched by our company, which can provide multi-functional, low-noise, high-gain erbium-doped fiber amplifier solutions, especially suitable for DWDM dense wavelength division multiplexing systems, and solve the problem of insufficient long-distance transmission power problem.
EDFA amplifier: it can be divided into power amplifier, line amplifier, and pre-amplifier from the application position.
LA line amplifier: It has the characteristics of low input power, low gain, high output, etc. It is mainly used in the middle of the two network nodes of the DWDM system to increase the transmission power of the DWDM system.
