RFA Raman Fiber Amplifier
Product Overview
The RFA amplifier card is developed by Visint® for dense wavelength division multiplexing optical communication systems, and is used in conjunction with EDFA amplification. Based on the stimulated Raman scattering (SRS) effect of fiber, it effectively overcomes the effects of nonlinear effects such as 4-wave mixing and improves the optical signal-to-noise ratio (OSNR) of the system and greatly extends the transmission distance.

Visint® Vispace 1000 series products optical amplifier equipment is widely used in data room interconnection, metropolitan area network, access network and other networks. The device is connected in series on the service line to efficiently re-amplify, re-time and re-shape the signal, completely transparent to the service, and supports multiple rates from 100Mbps to 100Gbps.
Multichannel amplification is an optical amplifier device (EDFA) connected in series in service line, which can amplify multiple wavelength optical signals in a single core optical fiber uniformly.
