Has multimode fiber become obsolete

Home / Has multimode fiber become obsolete

OM2 multimode fiber still supports cost-effective 1 Gbps and short-reach 10 Gbps deployments, yet OM3 and OM4 now dominate new data center and high-speed Ethernet builds. It just seems incredibly stupid to put the time and labor to lay a line that may be outdated within 10 years. OM1 (Optical Multimode 1) fiber optic cabling is considered an older and less capable multimode fiber type compared to more recent generations.
