GigaGuide™50 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 1300 nm
Fully compatible with standard 50/125
graded index multimode optical fiber
Proven Fiber
Performance for
High-Speed Networks
GigaGuide™ 50 multimode optical
fiber from Lucent Technologies
provides the increased bandwidth
and clear transmissions required by
today’s high-performance networks,
including Gigabit Ethernet. A new
high-speed design of a proven and
tested fiber solution, GigaGuide 50
combines Gigabit Ethernet capabili-
ties and full compatibility with your
installed base of standard 50/125
multimode optical fiber.
GigaGuide 50 is designed to provide
transmission distances up to 600
meters at both the 850 nm and 1300
nm windows, meeting or exceeding
the requirements for IEEE 802.3z
Gigabit Ethernet standards. With its
low attenuation (≤2.4 dB/km at 850
nm; and ≤0.7 dB/km at 1300 nm),
transmissions are clear and reliable.
Optimized for
Gigabit Ethernet
Like other graded-index multimode
fibers in the GigaGuide family,
GigaGuide 50 is specifically designed
to maximize the potential of the
Gigabit Ethernet standard. By
increasing transmission speeds
to 1,000 Mb/s (1 Gb/s), Gigabit
Ethernet architecture provides
optimal performance for those sites
where even Fast Ethernet speeds
are inadequate.
GigaGuide 50 is an excellent choice
both for Gigabit Ethernet installations
and for networks that may be
upgraded in the future. In Gigabit
Ethernet networks, this laser-certified
fiber provides outstanding perfor-
mance with both conventional edge
emitting lasers and Vertical Cavity
Surface Emitting Lasers (VCSELs).
For use with your installed base,
GigaGuide 50 is fully compatible with
all standard fiber optic network pro-
tocols including FDDI, Fast Ethernet
and 155 Mb/s ATM.

Advanced Processes,
Stringent Quality
Control
Robust and easy to connectorize,
GigaGuide 50 promotes ease of instal-
lation 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 tempera-
ture and humidity extremes, yet still
strips cleanly and easily.
GigaGuide 50 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 pro-
duces a range of multimode fiber
products that offer excellent perfor-
mance 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 per-
formance at 1Gb/s speeds.
Like all of Lucent’s graded index
multimode fibers, GigaGuide 50 fibers
are 100 percent quality tested in accor-
dance with the Telecommunications
Industry Association (TIA) Fiber
Optic Test Procedures (FTP) and
other industry standards.
