Introduction to eCPRI

eCPRI is short for enhanced Common Public Radio Interface, it is published after CPRI. eCPRI standard defines specification which connects eREC and eRE via fronthaul transport network. It is an important technology for understanding 5G systems, LTE-Advanced and LTE-Advanced Pro. Benefits of eCPRI Following are the advantages of eCPRI: It complies with IEEE 802.1 CM […]


Introduction 100G SFP56-DD transceivers

SFP-DD probably is the Next Generation SFP Module to Support 100G, It is based on 50G PAM4 signaling and will feature two channels, offering 100G in SFP-DD form-factor. By using this tiny SFP slot, it could realize the highest number of 100G front-panel pluggable ports in a Top-of-Rack switch. Eventually, two channels of 100G PAM4 […]
