GigaGuide™50 XL Optical Fiber
product fact sheet
key specifications
Core diameter: 50 ± 3 micron
Clad diameter: 125 ± 1 micron
Attenuation: ≤2.4 dB/km at 850 nm; and
≤0.7 dB/km at 1300 nm
Allows for Gigabit Ethernet operation up
to 600 meters at 850 nm and 2000 meters
at 1300 nm
Fully compatible with standard 50/125
graded index multimode optical fiber
Higher Bandwidth,
Longer Link Lengths
at 1Gb/s Speeds
GigaGuide™ 50 XL multimode optical
fiber from Lucent Technologies
provides increased bandwidth
over longer link lengths for Gigabit
Ethernet and other high-speed net-
works. 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 net-
works, 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 com-
patible with all standard fiber optic
network protocols including FDDI,
Fast Ethernet and 155 Mb/s ATM.

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.
