Single Jacket Multimode OM3 Multi-Core Mini Round Fiber Optic Cable
- 2000 MHz·km bandwidth for high-speed data transmission
- Future-proof solution for 40G/100G migrations
- Space-saving mini round design for dense patching
- Cost-effective alternative to OM4 for short-reach applications
- Backward compatible with existing OM1/OM2 infrastructure
The Multimode OM3 Multi-Core Mini Round Fiber Optic Cable is a high-performance, laser-optimized optical cable designed for 10G/40G/100G Ethernet and high-speed data transmission over short to medium distances. It features multiple 50/125µm OM3 fibers in a compact, lightweight round jacket, making it ideal for data centers, enterprise networks, and high-density installations.
OM3 fiber is laser-optimized (compliant with ISO/IEC 11801 & TIA-492AAAC), ensuring superior bandwidth and low modal dispersion compared to OM1/OM2.
FEATURES:
- Supports 10G/40G/100G Ethernet with low latency
- Better performance than OM1/OM2, suitable for evolving networks
- Mini round structure allows high-density cabling in racks
- Flexible, lightweight, and easy to route in tight spaces
- Laser-optimized for higher bandwidth (2000 MHz·km @850nm)
- More affordable than OM4/OM5 for most 10G/40G
