– Compatibility & Integration

This lens functions as an accessory within the HP 81000 series optical head connector adapter ecosystem. It interfaces directly with optical heads such as the HP 81521B and HP 81525A. Depending on the installed fiber connector type, specific adapters from the 81000 series may be required—including the 81000FA (FC/PC/SPC/APC), 81000KA (SC/PC/APC), 81000VA (ST), and 81003LA (LC) options. The modular design permits flexible configuration across multiple test system architectures.
