Why don’t data centers use multi-mode OM2 fiber anymore? In this article, ETU-Link will reveal the answer for you. Firstly, OM2 is mainly a traditional 50/125 micron graded index multi-mode fiber. OM2 fiber is based on LED light source in terms of standard and design, and has low bandwidth requirements. It cooperates with LED to transmit 1000Mbit/s and lower rates. OM2 will withdraw from the data ...
