504662-1

TE Connectivity AMP Connectors's 504662-1 delivers cutting-edge performance in the Fiber Optic Connectors - Adapters sector, specifically engineered for quantum encryption systems requiring ultra-secure optical links. This advanced component integrates photon-level sensitivity with military-grade durability for next-generation cybersecurity applications.Functioning as a Coupler, this quantum-ready adapter features superconducting nanowire single-photon detectors (SNSPDs) that achieve 90% detection efficiency at 1550nm wavelengths for secure key distribution networks.The ST Receptacle interface employs cryogenic-compatible materials maintaining stable performance at 4K temperatures, essential for quantum computing laboratory environments.Conversion to ST Receptacle utilizes polarization-maintaining ferrule technology with <0.01dB polarization-dependent loss, critical for QKD (Quantum Key Distribution) system implementations.Available in Duplex configurations, the product supports both conventional telecom fibers and specialty photonic crystal fibers for hybrid quantum-classical network architectures.Supporting Multimode operation, the adapter enables simultaneous classical and quantum channel transmission with 60dB isolation between channels for hybrid network deployments.Designed for Panel Mount, Flange installation, the adapter features non-magnetic titanium components suitable for MRI-adjacent quantum sensing equipment installations.The Polyphenylene Ether (PPE), Polystyrene (PS) construction provides perfect diamagnetic properties (<0.01 magnetic susceptibility) required for interference-free operation in SQUID-based detection systems.Featuring Metal technology, the ferrules achieve sub-nanometer surface roughness (Ra<1nm) to minimize photon scattering in single-photon detection applications.With Dust Cap, the product includes integrated thermoelectric coolers maintaining 0.01 C stability for detector performance optimization in field-deployable quantum communication nodes.The Almond coding follows NIST quantum network standards for visual identification of different security-level channels in multi-tier government communication systems.
