64 Ports High Power 1550nm Optical Amplifier CATV EDFA

Description

The 1550nm optical amplifier EDFA is high output power C-Band Er-Yb co-doped double cladding fiber optic amplifier. The key components of the product are 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 high stability and reliability output power, the unique optical circuit design ensures the excellent optical performance. The high stability and high precision MPU system to ensure the control, adjustment and display are intelligent and easy.

The EDFA employs 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.

The 1550 CATV EDFA employs intelligent temperature control system: (1)Adopt special temperature control circuit, heat radiating and power consumption can be reduced 30%, (2)The professional air flow design can also ensure the best temperature stability, at the same time powerful fan will start when the case temperature is over 45℃, meanwhile it will stop as the temperature is under 40℃. The technology makes sure the thermal stability of system and fan’s long life.

Intelligent network management system. Perfectly network interface: Ethernet network, and the open network management interface ensure the connectivity with all other network management system.

The EDFA is widely used in CATV transmission system and the high power distributing system FTTH requirement. It can be used for CATV analog/digital signal distribution, or match with PON system to construction the triple network integration. (Triple wavelength WDM is optional)
