    The Mini EDFA amplifier is high output power C-Band Er-Yb co-doped double cladding optical fiber amplifier. The key components of the edfa amplifier is made up of high reliability multimode PUMP laser and the double cladding optical fiber. A proprietary ATC (Automatic Temperature Control) and APC (Automatic Power Control) circuit insures the EDFA high stability and reliability output power. The unique optical circuit design ensures the excellent optical performance of the fiber amplifier. The high stability and high precision MPU system to ensure the control, adjustment and display are intelligent and easy.

    The fiber amplifier employ double cladding Erbium Ytterbium co-doped fiber, and employ the high power multimode pump, with a 10 times Conversion efficiency higher than the single mode general technology, and therefore have a lower relative cost and more compact size and lower power consumption, in particular, for FTTH or FTTB or other large distribution system applications.
