14 dB. Other attenuation values
available
n Simulates FDDI cable plant budget
n Compact package
n Mechanically and environmentally
stable

Applications
n Test an FDDI station
n Attenuate signal at cross-connect
panel
Tyco Electronic’s fixed value
attenuators use a patented
fused fiber technology that
relies on the natural physical
property of evanescent
coupling to create the desired
attenuation level.
Tyco Electronics’ Loopback
Attenuators utilize a unique
all-fiber mechanism to cause
a fixed attenuation of an
optical signal. There are no
filters, air-gaps, or core mis-
matches.
n Simulate system optical budget
n Shipping cover for transceiver
modules
