The FT III/IV – LC Receiver Adapter (1 × LC with Boot) is a precision instrument interface accessory designed to provide reliable photodiode/receiver connections for both multimode (50/125 µm) and single-mode (9/125 µm) testing on FiberTEK III and FiberTEK IV platforms. Engineered with a high-precision ceramic ferrule and low-loss mating sleeve, the adapter delivers repeatable optical coupling to instrument detector ports while minimizing insertion loss and preserving measurement accuracy across diverse field applications. The integrated protective boot safeguards the receiver interface from dust, impact and contamination during transport and use.

Compact and user-focused, this receiver adapter installs quickly and securely to the instrument, giving technicians immediate, dependable access to power and detector measurements without additional tools. The boot provides strain relief and easy removal while maintaining end-face cleanliness between tests. Durable metal construction and standardized LC termination ensure compatibility with existing patch cords and couplers, making the adapter a practical, low-overhead addition to any technician’s test kit for certification, troubleshooting, and routine verification of fiber links.
