Optical data networks form the backbone of today’s communications. Data centers, which seem to dominate any discussion of digital communications, depend heavily on fiber-optic connections from a few meters to many kilometers. Getting those bits…

Small form factor pluggable (SPF) technology was developed to support high-speed interconnects between servers, storage, and communications equipment in data centers and similar environments. Over time, the multi-source agreement (MSA) that specifies SPF has evolved to include new formats, including SFP, SFP+, SFP28,…
