Fiber Optic Cable Installation and Handling Instructions

Publication 2090-IN010C-EN-P – April 2005

Plastic Fiber Optic Cable Attenuation Limits

Plastic Fiber (POF) Attenuation Calculations:

POF Attenuation = Cable Loss + Connector Loss + Finishing Tolerance

POF Attenuation = (0.19dB/m * Length) + 1.5dB + 0.5dB

Catalog Number

Length meters,
(inches)

Maximum
