Optical Attenuators
Optical attenuators are used normally at optical receivers to adjust
for the optimum optical input power level to ensure proper operat-
ing parameters of the receiver. Both fixed (connectorized) attenu-
ator and variable (step) attenuators are available.
Step attenuators like the OTOA-1000 operate on the principle of
putting a “microbend” in the optical cable allowing some light to
escape the cladding, resulting in some light loss or attenuation.
The OTOT-1000 has a combination of 1, 2, and 4 dB loops that
when combined, can provide from 1 to 7 dB of attenuation in stan-
dard 3 mm singlemode optical cable at 1310 nm. Other cable or
wavelengths may result in different attenuation characteristics.
