Fiber Optic SC Cold Connectors and Couplers

SC cold connectors and couplers provide quick, tool-less fiber terminations and reliable optical alignment for single-mode and multimode networks.

SC Connectors Overview

The S

C (Subscriber Connector or Standard Connector) is a widely used fiber optic connector featuring a square, push-pull design with a 2. 5 mm ferrule, making it easy to insert and remove while maintaining precise fiber alignment.

S

C connectors are suitable for both single-mode and multimode fibers and are commonly used in Gigabit Ethernet, FTTx, and LAN applications. They provide low insertion loss, high return loss, and consistent optical performance, which is critical for minimizing signal degradation in fiber networks. Cold Connectors (Field-Installable)Cold connectors, also known as field-installable or mechanical connectors, allow fiber termination without fusion splicing or hand polishing.

Products like FASTConnect® SC connectors use a factory pre-polished fiber stub, index-matching gel, and mechanical splice technology to ensure precise alignment and low optical loss immediately upon installation. These connectors are compatible with 250 µm and 900 µm fibers, as well as 2 mm and 3 mm cordage, making them versatile for different cable types. They are ideal for quick deployment in enterprise, FTTx, and LAN networks.

S

C CouplersSC couplers are passive devices that join two SC connectors, enabling signal transmission between fibers. They are available for single-mode and multimode fibers, with Zirconia ceramic split sleeves for single-mode and OM3/OM4 multimode fibers, and PhBr metal sleeves for OM1/OM2 multimode fibers. Couplers can be mounted using stainless steel quick-mount clamps or flanged versions with screw holes for secure installation.

They comply with IEC 61754-4 and GR-326 standards, ensuring reliable performance under temperature extremes and rough handling.

Advantages of S

C Cold Connectors and CouplersTool-less installation reduces labor and deployment time. High precision alignment ensures low insertion loss and minimal signal reflection. Versatility: compatible with multiple fiber types and diameters.

Durability: robust polymer housing and ceramic sleeves maintain performance under mechanical stress. Ease of maintenance: connectors can be easily replaced or re-terminated in the field without specialized equipment. ApplicationsSC cold connectors and couplers are widely used in: FTTx networks for rapid deployment of subscriber connections.

Enterprise LA

Ns where quick, reliable fiber terminations are needed. Telecommunications and data centers requiring high-density, low-loss connections. In summary, SC cold connectors and couplers combine the reliability of traditional SC connectors with the convenience of field-installable technology, making them ideal for modern fiber optic networks that demand fast, precise, and low-loss terminations.
