Advancements in technology, combined with an increasing demand for higher port densities in servers and networking equipment, have led to the development of optical transceivers with decreasing footprints.
Transceivers have drastically decreased in size over the past 6 years, allowing data centers to become more efficient and streamlined. The following infographic illustrates the incredible rate at which fiber optic transceivers are shrinking. Starting with the XENPAK and shrinking all the way down to the SFP+.
