Longer Distances for Gigabit Ethernet Systems

GigaGuide 62.5 XL multimode optical fiber provides high performance over longer link lengths for Gigabit Ethernet and other high-speed transmission protocols. With the same outstanding quality and easy installation of Lucent's standard multimode fiber, GigaGuide 62.5 XL is fully compatible with your installed base of 62.5/125 multimode optical fiber.

Designed to carry the high bandwidth required by today's network users, GigaGuide 62.5 XL provides transmission distances up to 500 meters at 850 nm and up to 1000 meters at 1300 nm, and meets or exceeds all performance requirements for IEEE 802.3z Gigabit Ethernet standards.

Full Compatibility with Today's Networks

Today's traffic-intensive networks need the transmission speeds offered by Gigabit Ethernet architecture. To maximize the potential of this high-speed protocol, Lucent designed GigaGuide 62.5 XL specifically to provide long link lengths for 1 Gb/s transmission.

Laser-certified for use in Gigabit Ethernet applications, GigaGuide 62.5 XL offers outstanding performance with both conventional edge emitting lasers and Vertical Cavity Surface Emitting Lasers (VCSELs). GigaGuide is also fully compatible with all standard fiber optic network protocols including FDDI, Fast Ethernet and 155 Mb/s ATM, making it an excellent choice for new installations that may be upgraded to Gigabit Ethernet in the future.

Advanced Processes, Stringent Quality Control

GigaGuide 62.5 XL is specially designed for ease of installation. A tight (± 1 micron) specification on cladding diameter minimizes loss due to connectorizing. Lucent protects the fiber by using a dual-layered, UV-cured acrylate coating system. This coating provides excellent protection against temperature and humidity extremes, and it strips cleanly and easily for use in even the most challenging installation conditions.

GigaGuide 62.5 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 62.5 XL fibers are 100 percent quality tested in accordance with the Telecommunications Industry Association (TIA) Fiber Optic Test Procedures (FOTP) and other industry standards.
