Multimode Optical Fiber
OM3 / OM4 / OM5
Designed for short-distance, high-bandwidth data center interconnections, OM3, OM4 and OM5 graded-index multimode fibers support high-capacity links between servers, boards and switching equipment in intelligent computing network architectures.
Key Features
- High bandwidth, high stability and low latency
- Graded-index profile reduces dispersion and increases bandwidth
- Consistent geometric dimensions and bandwidth uniformity
- OM4+ and OM5 support evolution toward 800G and 1.6T rates
Applications
- Data center server and board interconnections
- 40G and 100G short-reach transmission
- High-density MPO cabling systems
- Intelligent computing network architectures
