OFS' 62.5 µm Laser Optimized Graded-Index Multimode Optical Fiber provides high performance over longer link lengths for Gigabit Ethernet and other high-speed transmission protocols. 62.5 µm Laser Optimized Fiber provides transmission distances up to 300 meters at 850 nm and up to 550 meters at 1300 nm. Fully compatible with your installed base of 62.5/125 micron multimode fiber, our 62.5 µm Laser Optimized Fiber allows for seamless upgrades of existing installations to 1 Gigabit per second (Gb/s) capability. The fiber meets or exceeds all performance requirements for Institute of Electrical and Electronics Engineers (IEEE) 802.3 Gigabit Ethernet standards.

Designed to carry the high bandwidth required by today’s network user, OFS’ laser optimized fibers maximize the performance of laser-based applications operating at 1 Gb/s transmission speeds. They are also completely compatible with all standard fiber optic network protocols including Fiber Distributed Data Interface (FDDI), Fast Ethernet and 155 Mb/s Asynchronous Transfer Mode (ATM). In Gigabit Ethernet networks, these laser-certified fibers offer outstanding performance with both conventional edge emitting lasers and Vertical Cavity Surface Emitting Lasers (VCSELs).
