Plug-Type (Male/Female) Attenuators
CMA series – Multimode
Description:
The plug-type CMA series multimodemode attenuators are used directly on the ends of fiberoptic
jumpers prior to installation in adapters. These attenuators provide a fixed precise level of attenuation
at defined wavelength. The CMA series multimode attenuators are available for SC, FC, ST and LC
connector types. Operational wavelength is 850 nm.
