Looking at the development of EDFA from the growth of 5G

5G is one of the hottest topics today. Compared with 4G, 5G has the advantages of faster speed, larger bandwidth, and lower latency. According to data released by the Ministry of Industry and Information Technology, more than 700,000 5G base stations have been built or opened, and high-speed construction is still in progress.

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
