Internet Protocol (IP) over DWDM’ is the concept of sending data packets over an optical layer using DWDM for its capacity and other operations. In the modern-day world, the optical layer has been supplemented with more functionality, which was once in the higher layers. This creates a vision of an all-optical network … Continued

With the development of data center with the broadband upgrade, optical module plays a more and more important role. We know that light modules have evolved over the years, The speed was increased from 10G to 800G, and the form factor was improved from 1X9 optical module to the current mainstream QSFP28, CFP2 optical module … Continued

EDFA is an optical amplifier that uses a doped optical fiber as a gain medium to amplify an optical signal. The signal which is to be amplified and a pump laser are multiplexed into the doped fiber, and the signal is amplified through interaction with the doping ions. EDFA is the best known and most … Continued
