WSEE's first SFP EDFA

The rapid growth of optical network deployment makes the iteration of optical transmission equipment more rapid, and most of the EDFA used in the current communication field are customized products.

Joint application of EDFA and Raman optical amplifier

EDFA products are mainly concentrated in C-band 1530nm~1565nm and L-band 1565nm~1606nm, Currently EDFA C-band dominate the market, but more and more manufacturers will have to focus attention on the L-band. Future development requires more transmission bandwidths of 1250nm~1650nm for optical amplifiers

Return Loss Test of Optical Index

Return loss, referred to as RL, uses the returned light wave to define the loss of the emitted light wave

Semiconductor optical amplifier SOA

Semiconductor Optical Amplifier is a kind of optical amplifier, a device that amplifies optical signals. Can be used to increase data transmission power and extend transmission distance
