This ST/UPC single-mode fiber patch cord is a robust long-haul interconnection solution for optical communication systems. It reliably connects optical transceivers, termination panels and network equipment to build continuous, stable optical transmission channels. Adopting light-based data transmission instead of electrical signals, it completely resists electromagnetic interference and crosstalk that troubles traditional copper cables. Featuring standard 9/125μm single-mode fiber with an 8–10μm ultra-fine core and low-refractive cladding structure, it effectively confines light waves and suppresses signal attenuation. Fitted with a fire-resistant yellow LSZH outer jacket, it complies with IEC and RoHS environmental and safety standards. Available in standard 1m–4m lengths, this eco-friendly pre-terminated cord delivers ultra-stable low-loss performance, perfectly adapting to long-distance, high-bandwidth optical network deployment.
1.Precision ST/UPC termination ensures excellent optical transmission quality
Equipped with high-durability zirconia ceramic ferrules and UPC ultra-precision polishing, factory-terminated ST/UPC connectors achieve insertion loss ≤0.3dB and return loss ≥50dB. Consistent optical performance eliminates signal jitter and packet loss, delivering reliable and continuous data transmission for all single-mode network scenarios.
2.Low-attenuation single-mode fiber supports long-distance networking
Adopting industry-standard 9/125μm single-mode fiber, this yellow patch cord features ultra-low attenuation: ≤0.35dB/km at 1310nm and ≤0.21dB/km at 1550nm. It supports stable signal transmission over 10 kilometers, perfectly suited for campus backbone networks, telecom trunk lines, cross-building links and other long-haul optical communication projects.
3.Bayonet twist-lock structure provides anti-vibration and anti-drop performance
The exclusive ST bayonet rotating locking design achieves tight mechanical engagement after installation. It effectively prevents loose connection and accidental disconnection caused by equipment vibration, cable pulling and environmental shaking. It maintains uninterrupted network operation in industrial workshops, outdoor cabinet stations and other harsh scenarios, greatly reducing daily maintenance frequency.
4.LSZH zero-halogen jacket upgrades overall fire safety level
Low Smoke Zero Halogen outer sheath produces barely any toxic gas or dense smoke during combustion. Meeting international IEC and RoHS specifications, it provides superior fire resistance and environmental safety. It is the ideal wiring choice for data centers, schools, hospitals, commercial buildings and public facilities with strict fire protection regulations.
5.Flexible length options realize standardized and clean cabinet management
Standard stocked sizes include 1m, 2m, 3m and 4m, with customizable non-standard lengths available for project demands. Appropriately sized patch cords avoid redundant cable loops and messy routing, improving cabinet ventilation and heat dissipation. Fully compatible with mainstream ST adapters and fiber distribution frames, it ensures universal adaptability for various single-mode network architectures.
