FIXED ATTENUATORS
(BUTT JOINT STYLE)
FEATURES:
• Low backreflection
• Compact and rugged housing
• Singlemode attenuator uses a high loss splice for
patchcord version or high loss fiber for hybrid inline
attenuator version
• Multimode attenuator uses a neutral density filter
• Wide wavelength range
• Wide range of connectors
• Polarization maintaining fiber version also available
• Polarization insensitive
• Loopback style attenuators are also available.
•LOW COST!
APPLICATIONS:
•CATV, LAN, and telecommunications use
• Receiver padding
• Test and measurement
• Optical power equalization
SPECIFICATIONS:
•Attenuation range: 5 to 25 dB with 5dB increments
Other attenuation values in 1dB
increments are also available
•Attenuation tolerance: ±10% of the specified
attenuation level in dB
•Polarization dependent loss: ±1% of the specified attenuation
level in dB
•Available wavelengths: 440-1625 nm
•Return loss: 40, 50, or 60dB for singlemode
fibers
•Operating temperature: -40°C to +80°C

Wavelength: Specify in nanometers
(Example: 1550 for 1550nm)
Example: A 20dB fixed attenuator is required for 9/125 singlemode fiber, with an operating wavelength of 1300nm. The input
connector is to be a female receptacle for angled FC connectors, while the output connector is a male SC connector.
