ESC920H SC/UPC Fast Connector

We deployed a bulk order of these ESC920H SC/UPC fast connectors across our urban FTTH subscriber installations. A major advantage for our field crews is the versatile cable clamp design, which accommodates 3.0mm, 2.0mm, and 0.9mm fiber cables within a single housing. The field assembly procedure takes approximately 1 minute per termination, yielding a field success rate well above 98%. Insertion loss consistently measures under the 0.3dB typical threshold across 1310nm and 1550nm test wavelengths, making these field-installable connectors a cost-effective alternative to fusion splicing on customer premises.

As a telecom network deployment manager, ensuring mechanical durability and compliance with strict industry standards is critical. The ESC920H SC/UPC connector features a compact 45.5mm length that fits neatly inside crowded wall sockets and distribution boxes. Its robust locking mechanism delivers a tensile strength exceeding 50N, fully complying with Telcordia GR-326-COR tensile testing and YD/T 2341.1-2011 standards. Furthermore, being reusable for at least 5 times allows our field technicians to quickly re-terminate any improper cleaves on site without wasting hardware.

We procured these SC/UPC quick connectors to upgrade legacy drop cable terminations across our regional network. Built for 125μm single-mode fibers with 900μm coating (supporting both G.652 and G.657 glass types), they provide a solid Ultra Physical Contact (UPC) return loss of ≥50dB. Their operating temperature range of -40 to +85°C ensures zero signal degradation when installed in unconditioned outdoor cabinets. Even under on-line 20N tensile and 4-meter drop tests, optical insertion loss remains stable at ≤0.3dB. FirstFiber delivers exceptional quality across every batch.
