Fiber Optic Adapter/Attenuators

Fiber Optic Standard Coupler, FC to FC Simplex, Round thru-hole mount, metal housing Ceramic Alignment Sleeve

Item Description

Flat FC/PC connectors are significantly less alignment sensitive than their angled FC/APC counterparts, making these wide-key-slot mating sleeves acceptable for narrow and wide key FC/PC connectors. Although these mating sleeves are mechanically compatible with narrow key FC/APC connectors, the wide-key slot makes it difficult to properly align the angled, narrow key FC/APC connector. For FC/APC applications, we therefore recommend the narrow-key-slot mating sleeves shown immediately below. All FC/PC and FC/APC patch cables manufactured by Thorlabs use narrow key connectors. Each mating sleeve includes two protective caps that shield the connectors from dust and other contaminants. These caps should be removed before use. Please note that the size of these caps may vary from lot to lot. The CAPF1 metal cap is also available for use when these mating sleeves are mounted into our L-Brackets, sold below.
