Vertical cavity surface emitting lasers (VCSELs) are key enabling devices meeting the requirements of optical interconnects in such data centers up to a few hundred meters of single or multimode fiber due to their simplicity, low cost, and large data transmission rates. Achieving higher bit rates has been the stated goal of research and development during the last years.
Multimode Fiber is still the front runner in modern Enterprise Data Centers as it provides a low-cost way to transport high data rates over relatively shorter or smaller distances. MMF has evolved from being optimized for multi-megabit-per-second transmission using LED light sources to being optimized for supporting multi gigabit transmission using 850m VCSEL (Vertical Cavity Surface Emitting Laser), which tend to be more affordable than their single mode counterparts.
