Fixed Fiber Optic Attenuators, Single Mode
Fiber Attenuator / Terminator Kit, FC/APC Connectors (Not to Scale)
1240 - 1620 nm
1240 - 1620 nm
Thorlabs' Single Mode Fixed Fiber Optic Attenuators allow one to attenuate an optical signal easily by plugging an FC/PC- or FC/APC-terminated fiber directly into the back end of the attenuator connector. The input of the attenuator has a 2.2 mm wide key female connector, making it compatible with both narrow key and wide key male connectors. The output of the attenuator has a 2.0 mm narrow key male connector (either FC/PC or FC/APC). These single mode attenuators are made with polarization-insensitive doped fiber to achieve the specified attenuation over operating wavelength ranges between 1240 - 1620 nm.
Every attenuator includes connector caps. For replacements, plastic FC connector and mating sleeve caps are available.
Thorlabs' Fiber Optic Attenuator and Terminator Kits each contain six fixed attenuators, five terminators, and a selection of dust caps. Components in the FAK03 kit have FC/PC connectors while those in the FAK05 kit have FC/APC connectors. Each kit is packaged in a plastic box measuring 7.0" x 3.5" x 1.25" (177.8 mm x 88.9 mm x 31.8 mm) and has nine labeled compartments. The label on the lid indicates the contents, associated Thorlabs item number (where applicable), attenuation value and tolerance for the attenuators, and wavelength range and return loss for the terminators. The table to the right lists the description and quantity of each item included in these kits.
