1652978

Phoenix Contact's 1652978 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 SCRJ Receptacle interface employs cryogenic-compatible materials maintaining stable performance at 4K temperatures, essential for quantum computing laboratory environments.Conversion to SCRJ 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 Singlemode/Multimode operation, the adapter enables simultaneous classical and quantum channel transmission with 60dB isolation between channels for hybrid network deployments.Designed for Free Hanging (In-Line) installation, the adapter features non-magnetic titanium components suitable for MRI-adjacent quantum sensing equipment installations.The Polybutylene Terephthalate (PBT) construction provides perfect diamagnetic properties (<0.01 magnetic susceptibility) required for interference-free operation in SQUID-based detection systems.Featuring Zirconia technology, the ferrules achieve sub-nanometer surface roughness (Ra<1nm) to minimize photon scattering in single-photon detection applications.The Black coding follows NIST quantum network standards for visual identification of different security-level channels in multi-tier government communication systems.
