2mm SC-SC Single Mode Duplex Fiber Jumper (50m)

2mm SC-SC Single Mode Duplex Fiber Jumper (50m) is a carrier‑grade optical patch cable designed for stable long‑distance data transmission in fiber communication infrastructure. The 9/125μm single‑mode duplex fiber structure supports precise light propagation while reducing attenuation over extended distances. A durable 2.0mm outer diameter balances flexibility and mechanical strength, making the cable suitable for structured cabling and equipment interconnection. Ceramic‑ferrule SC connectors ensure accurate alignment and dependable signal coupling, enabling reliable performance in telecom systems, enterprise networking environments, and optical data distribution applications where signal integrity and durability remain critical.

Single‑Mode Duplex Architecture for Long‑Distance Transmission

This fiber optic patch cable adopts a single‑mode 9/125 (G652D) duplex structure that supports a single light propagation mode, significantly reducing modal dispersion across long transmission distances. Dual‑core fiber design integrates two independent optical paths within one cable assembly, enabling simultaneous bidirectional communication between networking devices. Such architecture is widely applied in backbone fiber connections, telecom distribution systems, and long‑range optical data links requiring consistent signal quality across wavelengths ranging from 1310nm to 1550nm.

Precision Ceramic Ferrule SC Connectors

Each end of this optical fiber jumper features SC square connectors equipped with high‑precision ceramic ferrules that maintain stable fiber alignment. Accurate core positioning reduces insertion loss while maintaining excellent return loss performance. The connector interface also provides reliable repeatability and interchangeability, supporting frequent equipment switching in patch panels, optical distribution frames, and network devices. A durable PBT connector shell further enhances structural stability and protects internal components during installation and repeated use.

Durable Construction for Carrier‑Grade Reliability

The 2.0mm cable jacket and reinforced internal structure provide strong tensile resistance up to 100N while maintaining a bending radius of 30mm for flexible routing in racks or conduits. High durability supports more than 1000 insertion and removal cycles without performance degradation. Combined with wide operating temperature tolerance from -40℃ to +80℃, this optical patch cord meets carrier‑grade reliability requirements for demanding networking environments.

Common deployment scenarios include optical fiber communication systems, access networks, backbone data transmission links, and local area network infrastructure. This duplex optical cable supports stable connections between fiber switches, transceivers, and distribution frames, delivering dependable optical signal transmission across enterprise, telecom, and industrial networking environments.
