Быстроразъемный оптический коннектор SC APC

We deployed these SC APC fast connectors across a major municipal FTTH project to terminate 2x3mm flat drop cables directly at customer ONU/ONT terminals. The factory pre-polished 8° ±0.3° APC ferrule eliminates the need for field fusion splicing while keeping back reflection exceptionally low. Across over 1,200 field terminations on G657A1 single mode fiber, our OTDR verification yielded a typical insertion loss around 0.3dBm, well within the maximum ≤0.5dBm specification. A massive operational advantage for our installers is the reusability feature—connectors can be re-terminated up to 5 times if initial stripping alignment needs adjustment, preventing material waste and ensuring high first-pass yield.

In our outdoor optical distribution network audits, component reliability under severe environmental stress is paramount. These field fast assembly connectors comply fully with Telcordia GR-326 standards for thermal cycling, humidity aging, impact, and vibration. We use them extensively inside outdoor distribution boxes to route 2x3mm drop cables from PLC splitter adapter panels. The internal clamping mechanism delivers a 40N tension resistance with mechanical durability under ≤0.3dB attenuation variance. Having a broad operating temperature range of -40°C to +85°C guarantees long-term optical link stability inside unconditioned outdoor cabinets across all seasons.

Transitioning our subscriber drop installations to fast field assembly connectors reduced our average site provisioning time by over 60%. This SC APC quick connect device is specifically engineered for 2x3mm flat drop cables and seamlessly accepts ITU G657A, G657B, and G652D single mode fibers with standard 125μm cladding and 250μm coating. The precision internal fiber guide ensures exact physical alignment against the internal index-matched fiber stub. Our QA lab tested tensile strength at 20N and confirmed the attenuation delta stayed well under ≤0.3dB. It offers enterprise-grade optical performance and mechanical durability for last-mile subscriber connections.
