Middle stage access EDFA Optical Amplifier-PA Card
● C-band optical signal overall amplification
● Covering the wavelength range of 1528 ~ 1565nm
● Support systems to achieve different cross-section radio repeater transmission

With the application of long-distance systems becoming more and more extensive, our company‘s self-developed middle stage access (MSA) EDFA, middle stage access (MSA) EDFA can effectively solve the insertion loss caused by DCM and OADM, offset the DCM and OADM bands. The resulting insertion loss reduces the additional degradation of the system OSNR.
Middle stage access (MSA) EDFA models include an additional mid-stage port designed for insertion of a Dispersion Compensation Management (DCM) unit without its inherent insertion loss.
The design of these models maximizes the DCM benefits to increase deployment flexibility.New placement options require fewer amplifiers in the link, and they can open the door to applications that were not possible with older technology.
