The HP Agilent Keysight 81000VA is an ST connector adapter designed for fiber optic test equipment. It provides a threaded interface that connects ST optical connectors to Agilent 815xxx and 816xxx series optical heads, enabling rapid reconfiguration of measurement setups without replacing optical head assemblies. This adapter is engineered for 5 mm optical head interfaces and integrates into the 81000 series connector adapter family.

– Compatibility & Integration
The 81000VA operates with Agilent 815xxx and 816xxx series optical heads. It functions as a member of the broader 81000 series adapter family, which includes FC/PC/SPC/APC (81000FA), SC/PC/APC (81000KA), and E-2000 (81000PA) variants. Accessory integration supports filter holders (81000AF), filter holders with lenses (81050BL, 81010BL), and bare fiber adapters (81000BA) rated for 125-micrometer cladding fibers. This modularity allows users to construct custom optical measurement chains matched to specific test requirements.
