Erbium Ytterbium Doped Fiber Amplifier (EYDFA)

PPC’s high power Erbium Ytterbium Doped Fiber Amplifier (EYDFA) is characterized by low noise and high linearity performance to meet the most demanding requirements of CATV and FTTx applications. It offers a flexible and low-cost solution for CATV large area coverage of large and medium-sized cities, mainly used in FTTH, FTTB, DBS, MMDS and FTTx PON architectures. The device has a built-in CWDM multiplexer, which will enable the 1490 / 1310nm data stream of the OLT and ONU to be combined into a single fiber transmission through EDFA, thereby reducing the number of devices and improving the system index and reliability. Our EDYFA provides a flexible and low-cost solution for triple play and fiber-to-the-user (FTTU). 

High Quality: Former-class pump uses 980 nm and after-class pump uses 1480 nm. Power is optimized by software to minimize the NF of the EDFA. 

Reliability: The 2U standard rack has a built-in high-performance switching power supply and can work at 85 - 265 VAC city network voltage. There is an optional DC48V power supply (reservations required), and the chassis has automatic cooling temperature control. 

Intuitive: The EDYFA is equipped with a microprocessor that monitors the working state of the laser and an LCD window display that displays the operating parameters. 

Network Type: The select all-piece status monitoring transponder is guaranteed to meet the national standard and be compatible with the SCTE HMS standard, enabling network management monitoring capabilities. Power Plug: The aluminum structure, using plug switching power supply, allows for heat dissipation and replacement.
