A Guide to Multimode Fiber Types (OM1-OM5) –
Multimode fiber is a kind of optical fiber mostly used in communication over shorter distances, for example inside a building or for the campus.
Read MoreHome / Why is multimode fiber 50 micrometers
Multi-mode optical fiber features a larger core diameter (typically 50–100 μm), allowing multiple light modes to propagate simultaneously. This design simplifies alignment and installation, making MMF cost-effective and ideal for short- to medium-distance data transmission in enterprise networks, and campus environments. MMF supports high data rates—up to 100 Gbps—over distances typically ranging from 300 to 550 meters, depending on fiber type (OM3, OM4, OM5). This enables higher launch tolerance but also introduces modal dispersion over distance.
