Corning Infinicor 300 is Corning's laser optimized 62.5/125µm multimode fiber for high speed, VCSEL laser-based local area networks (LAN) and local access networks. It guarantees the bandwidth of 1Gb/s over 300m at 850nm and 1Gb/s over 550m at 1300nm.

In today's enterprise networks, bandwidth demands are growing - rapidly. That's because end-user productivity is increasingly dependent on instant accessibility and high throughput of information. Narrow bandwidth constricts your capacity to succeed. Corning's 62.5 µm InfiniCor fibers, the world's first laser-optimized 62.5 µm multimode fibers, help you to stay ahead of escalating network demands with:

  • Greater distance capability at data rates up to 1 Gb/s in both the 850nm and 1300 nm windows
  • Higher data aggregation in the backbone, riser and horizontal, compared with non-laser-optimized fibers
  • Full compatibility with the broad range of laser-based and legacy protocols and applications
  • Superior measurement technology and manufacturing control
  • Industry-leading CPC coating for superior microbend and environmental performance

Thoroughly Measured for Performance You Can Count On

Corning Fiber is a world leader in developing and using the most advanced measurement techniques for laser optimized multimode fibers. In fact, InfiniCor fibers are more thoroughly measured than any other multimode fiber on the market. Corning uses direct manufacturing process controls and final product measurements for all InfiniCor fibers to ensure performance in laser-based systems.
Corning Fiber provides restricted mode launch (RML) bandwidth measurements for InfiniCor 300 62.5 µm optical fibers. The RML bandwidth metric is a standards-defined method that predicts intermediate-bandwidth, laser-based system performance. Corning was the first optical fiber manufacturer to offer RML measurements for its laser-optimized multimode fibers.
