The TRIAX TFA 10 SC/APC, 10 dB optical attenuator is a passive single‑mode fibre component that reduces incoming optical signal power by a fixed 10 dB. With angled SC/APC connectors for low back‑reflection, it ensures optical receivers operate within their optimal dynamic range and helps balance signal levels in passive optical networks, telecom and CATV applications. Attenuators like this are commonly used to prevent receiver overload when signal power is too high.
