Alcatel Multimode
Fiber 100/140
IEC Ref.A1b
Fiber Optic Product Line issue : April 1998 1/2
Largecore Multimode graded index
100/140 fibers are used in local area
networks for video and data
transmission for short distance links
e.g. on board aircraft cables, video
surveillance.
It runs the different standards of the
market : FDDI, Token-Ring, Ethernet,
ATM, ....
Process
The fibers are manufactured using
the Alcatel APVD process. This is a
deposition of Silicium dioxide and
germanium dioxide inside a silica
tube.
The Alcatel APVD Process has been
specifically developed for a mass
production of fibers with a high level
of reproducibility.
The fiber operates at both wavelength
regions 850nm and 1300 nm.
They are produced and controlled
according to the international
standards :
IEC pub 793/2 for the product.
IEC pub 793/1 for the measurement
methods.
