GigaGuide 50 XL combines the proven technology of 50 micron multimode fiber, Gigabit Ethernet transmission capability, and full compatibility with your installed 50/125 multimode optical fiber base. GigaGuide 50 XL is designed to provide transmission distances up to 600 meters at the 850 nm window and 2000 meters at the 1300 nm window, meeting or exceeding the requirements for IEEE 802.3z Gigabit Ethernet standards. GigaGuide 50 XL's low attenuation ( 2.4 dB/km at 850 nm and 0.7 dB/km at 1300 nm) ensures clear, reliable transmissions. High Performance at Any Speed Gigabit Ethernet architecture provides optimal performance for those sites where even Fast Ethernet speeds are inadequate. GigaGuide 50 XL is specifically designed to provide long link lengths at 1Gb/s speeds. Whether you need fiber for a new Gigabit Ethernet installation or to expand your existing multimode network, GigaGuide 50 XL is a wise investment. In Gigabit Ethernet networks, our laser-certified GigaGuide 50 XL fiber provides outstanding performance with both conventional edge emitting lasers and Vertical Cavity Surface Emitting Lasers (VCSELs). For use with your installed base, GigaGuide 50 XL is fully compatible with all standard fiber optic network protocols including FDDI, Fast Ethernet and 155 Mb/s ATM. product specifications GigaGuide 50 XL Optical Fiber TM GigaGuide meets or exceeds industry standards for fiber specifications.

Environmental Performance Maximum induced attenuation @ 850 nm and 1300 nm from -60C to +85C (dB/km) 0.20 Maximum induced attenuation @ 850 nm and 1300 nm from -10C to +85C, 85% RH 30 day cycle (dB/km) 0.20 Advanced Processes, Stringent Quality Control Robust and easy to connectorize, GigaGuide 50 XL promotes ease of installation even under the most challenging conditions. Lucent protects the fibers by using a dual-layered, UV-cured acrylate coating system that provides excellent protection against temperature and humidity extremes, yet still strips cleanly and easily. GigaGuide 50 XL is manufactured at Lucent's Multimode Center of Excellence (Sturbridge, Massachusetts) using the company's advanced Inside Vapor Deposition (IVD) technology. Using the IVD process, Lucent produces a range of multimode fiber products that offer excellent performance for all transmission protocols. The IVD method enables Lucent to precisely control each fiber's index of refraction. Under the restricted launch conditions used in Gigabit Ethernet, this maximizes fiber bandwidth performance at 1Gb/s speeds. Like all of Lucent's graded index multimode fibers, GigaGuide 50 XL fibers are tested and proven to exceed the Telecommunications Industry Association (TIA) Fiber Optic Test Procedures (FTP) and other industry standards. GigaGuide's dual layer UV-cured acrylate coating provides excellent fiber protection and strips cleanly and easily.
