EDFA is the abbreviation of English "Erbium-doped Optical Fiber Amplifier", which means Erbium-doped Fiber Amplifier,

It is an active optical device that amplifies signal light

​

Today, optical cable networks have spread all over the world, and optical fiber communication has become an important pillar of the "information superhighway". However, due to the transmission loss of the optical fiber itself, the optical signal can only be transmitted over a short distance, and it will be attenuated to the extent that the receiver cannot distinguish it. From the front optical relay, the "optical-electrical-optical" method is used for optical amplification. A revolution in optical communication technology caused by the advent of EDFA plays an important role in the systems of post and telecommunications, cable television and computer networks that use optical fibers as transmission media.

Features

The module is an integrated erbium-doped fiber amplifier, which is divided into two types: optoelectronic integrated EDFA module and optical gain module. It has the characteristics of small size, low power consumption, and convenient use. It can be easily installed in various Such application systems, such as SDH rack, CATV box, DWDM system rack.

advantage

1. High quality: The pre-stage pump is generally 980nm, and the post-stage pump is 1480nm. The power is reasonably optimized by software to minimize the NF of the EDFA, which is comparable to the so-called low-power optical amplifier. The system can obtain excellent CNR.

2. Reliability: It adopts 19″1U standard rack, built-in high-performance switching power supply, can work in 85∽265Vac mains voltage, and can also choose DC48V power supply (reservation required); chassis heat dissipation can be automatically controlled by temperature.

3. Intuitiveness: The pump laser is the most expensive component of the whole machine. The machine is equipped with a microprocessor to monitor the working state of the pump laser, and the working parameters are displayed by the panel LCD window.

Function

1. Network management type: The optional status monitoring transponder is guaranteed to meet the national standard and is compatible with the SCTE HMS standard, which can realize the network management monitoring function.

2. Power plug-in type: The plug-in type switching power supply adopts aluminum profile structure, which is conducive to heat dissipation and replacement. And dual power hot and cold backup.

3. Adjustable output optical power: the adjustable range of output optical power (-3dB), users need to specify when ordering.
