Alcatel-Lucent 3AL79340AAAC S-4.1 Optical Interface FC/PC Connector

The Alcatel-Lucent 3AL79340AAAC S-4.1 Optical Interface FC/PC is a fiber optic connector assembly designed for STM-4/OC-12 optical interface connectivity in SDH/SONET transport network equipment. This component provides precision optical fiber termination and interconnection for short-reach 622 Mbps optical transmission applications per ITU-T G.957 S-4.1 interface specifications. The FC/PC (Ferrule Connector with Physical Contact polish) connector features a threaded coupling mechanism providing secure, low-loss optical connections with typical insertion loss below 0.3 dB and return loss exceeding 40 dB. The connector utilizes a 2.5mm ceramic ferrule with precise fiber alignment to ensure optimal optical performance and minimal back reflection. The S-4.1 designation indicates compatibility with short-reach STM-4/OC-12 optical interfaces operating at 1310 nm wavelength over single-mode fiber (ITU-T G.652) with typical reach up to 15 kilometers. The connector assembly features robust metal housing with nickel-plated brass construction for durability and electromagnetic interference (EMI) protection. Precision polishing ensures optimal fiber end-face geometry per IEC 61755 standards with scratch-dig specifications for long-term reliability. The FC/PC connector is compatible with industry-standard adapter panels, patch panels, and optical distribution frames in telecommunications central offices and remote installations. Applications include interconnection of optical transport equipment, cross-connect panels, optical test equipment, and fiber distribution systems in SDH/SONET network deployments. The connector supports operating temperatures from -40 °C to +85 °C and complies with IEC 61753, Telcordia GR-326, and EIA/TIA-455 standards for fiber optic connector performance and environmental reliability.
