Corning® ClearCurve® Multimode Optical Fiber
Product Information
Bend Performance and Compatibility
Corning ® ClearCurve ® ultra-bendable laser–optimized™ multimode optical fiber delivers the best macrobending performance in the industry while maintaining compatibility with current optical fibers, equipment, practices and procedures. ClearCurve OM 2, OM 3 and OM 4 multimode fiber is designed to withstand tight bends and challenging cabling routes with substantially less signal loss than conventi
onal multimode fiber. This new multimode optical fiber allows designers, installers and operators of enterprise networks (including local area networks, data centers and industrial networks) to use multimode optical fiber in a package that is easier to handle and install. With greater signal protection when subjected to tight bending, ClearCurve offers greater system security and reliability meaning maximized network up-time and lower associated maintenance costs.Building on the proven bandwidth capability of Corning’s InfiniCor ® fibers, the world’s first laser-optimized™ multimode fibers, ClearCurve multimode fibers increase your capacity to succeed:
• Industry leading macrobending performance below 10 mm radius
• High performance minEMBc certified bandwidth to support 850 nm transmission at data rates up to 100 Gb/s
• Higher data aggregation in the backbone, riser and high-speed parallel interconnects (HSPIs)• Fully backwards-compatible and ideally suited to current and future broad range of laser-based protocols and applications
• Superior measurement technology and manufacturing control
• Industry-leading CPC ® coatings for superior microbend and environmental performance

* D istances specified in the 40G/100G per IEEE 802.3ba standard are 150m on OM 4 and 100m on OM 3; Corning fibers are manufactured
to tighter dispersion specifications and thereby support the extended distances shown in the table (assuming cable attenuation ≤3.0 dB/km and same 1.0 dB of connector loss for OM 3 that the standard requires for OM 4).
The Smart, Reliable, Cost-Effective Network Choice
合胞
病毒No one can match Corning’s superior measurement technology and manufacturing control of the refractive index profile. Consequently, ClearCurve multimode optical fibers deliver exceptional high bandwidth and superior transmission performance for the most demanding applications, while allowing the use of low-cost, high-speed 850 nm vertical cavity surface-emitting lasers (VCSELs).
High Bandwidth Performance You Can Rely On
Corning is a world leader in developing and using the most advanced measurement techniques for laser-optimized multimode fibers. Corning uses direct manufacturing process control and integrated measurement techniques for all ClearCurve fibers to ensure robust performance in laser-based systems.
We ensure EMB via calculated effective modal bandwidth (minEMBc) for all our ClearCurve multimode optical fibers. minEMBc is a differential mode delay (DMD) - 100% measured bandwidth method that best predicts multimode performance in high-bandwidth laser-based systems up to and including 100 Gb/s. Corning was the first optical fiber manufacture to provide customers with minEMBc measured bandwidth values for individual laser-optimized multimode fibers.
