LaserWave® FLEX 300/550 (OM3/OM4) Fibers are 50 micron (μm) laser-optimized multimode fibers designed to support 10 Mb/s through 400 Gb/s applications in data centers, high performance computing centers and enterprise LANs with superior bending performance, enhancing fiber management and low-cost connectivity.
LaserWave Fiber extends the application of multimode fiber to support transmission speeds to 400 Gb/s and beyond. Using low-cost Vertical Cavity Surface Emitting Laser (VCSEL) transceivers, the fiber supports a wide variety of applications including Ethernet, Fibre Channel, InfiniBand and Optical Internetworking Forum (OIF) solutions.
Using state of the art process control, Lightera LaserWave fiber is manufactured to the tightest geometry and optical specifications in the industry. Tighter specifications lead to lower variation when mating fibers in fiber optic connectors, and lower insertion loss. Today’s high speed 100 and 400Gb/s applications have extremely low loss budgets, and low connector loss and fiber attenuation is key to supporting these links. The fiber offers extremely low bending loss at both the 850 and 1300 nm operating windows, while maintaining excellent long-term fiber strength and reliability. LaserWave FLEX Fiber can be installed in loops as small as 7.5 mm radius with less than 0.2 dB bending loss at 850 nm and 0.5 dB at 1300 nm. This improved performance can guard against instances of higher loss caused by tight bends, thereby increasing system reliability and maximizing network uptime.

Lightera multimode fibers are made with a world-class draw process and our enhanced D-LUX Shield Coating, designed to minimize induced attenuation that can occur in tight-buffer cable. Easy to strip and install, the coating offers outstanding performance in attenuation-sensitive systems up to 400 Gb/s.
LaserWave FLEX OM4 and OM3 Fiber provides improved performance above the minimum required by the standards. Lightera’ advanced MCVD process used to manufacture LaserWave FLEX Fibers eliminates the center defect problems that can plague fibers manufactured with other processes. The Inner DMD mask for LaserWave FLEX Fiber is expanded to a range from 0 to 18 µm radius versus the less stringent 5 to 18 µm radius allowed by TIA and IEC. This reduces fundamental and very low-order mode DMD for improved operating margin and superior support of concentrated center-launch lasers. This results in LaserWave FLEX Fiber DMD up to 60% better than what the standard allows in the center portion of the fiber and improves system reliability margins versus other DMD controlled fibers. LaserWave FLEX Fiber meets and exceeds the specification requirements of both the EMBc and the more discriminating DMD mask methods for verifying Effective Modal Bandwidth. Both techniques are recognized and approved industry standards; however the DMD mask method allows for closer scrutiny of fiber characteristics, enabling LaserWave FLEX to be specified to more stringent DMD specifications than required by the standards. This provides increased performance and reliability for your network. Lightera LaserWave FLEX Fiber specifications exceed the reliability requirement of the IEEE Ethernet standards, providing assurance for 100% functional system reliability.
