Product Details

Overview

4 Port EDFA High Power, output optical power 23dBm, power AC 220V, can be used for CATV analog/digital signal distribution, or match with PON system to construction the triple network integration.

The 4 Port EDFA is a C-Band Er-Yb co-doped double cladding optical fibre amplifier with a high output power. The high-reliability multimode PUMP laser and the double-cladding optical fibre are the product’s main features. The high stability and dependability output power is ensured by a proprietary ATC (Automatic Temperature Control) and APC (Automatic Power Control) circuit, while the unique optical circuit design assures exceptional optical performance. The MPU system’s excellent stability and precision enable intelligent and simple operation, adjustment, and display.

The EDFA Amplifier uses double-cladding Erbium Ytterbium co-doped fibre and a high-power multimode pump with a 10 times higher conversion efficiency than single-mode general technology, resulting in a lower relative cost, smaller size, and lower power consumption, which is ideal for FTTH, FTTB, and other large distribution system applications.
