SC to ST fiber optic patch cord single-mode

ST-SC single mode fiber optic patch cords are high-performance cables designed for long-distance, low-loss optical transmission, featuring ST and SC connectors on either end.Overview

An ST-SC fiber optic patch cord is a type of single mode (9/125µm) fiber cable that connects devices with ST and SC ports. These cables are commonly used in telecommunication networks, data centers, and enterprise fiber-optic systems where reliable, high-speed, and long-distance signal transmission is required . Single mode fiber supports long-distance communication due to its low attenuation and narrow core, making it ideal for backbone and inter-building connections .

Connectors

• ST Connector: Features a round body with a bayonet-style twist-lock mechanism. It is easy to insert and remove, commonly used in early LANs and fiber patch panels, and provides low insertion loss .
• SC Connector: Square body with a push-pull latch, offering good mechanical stability and low cost. It is widely used in switches, routers, and GBIC transceivers . The combination of ST and SC connectors allows compatibility between devices with different port types, ensuring flexible network integration.

Cable Specifications

• Fiber Type: Single mode OS2, 9/125µm core/cladding diameter .
• Jacket Material: Options include OFNR (riser-rated), LSZH (low-smoke zero halogen), and plenum-rated for air-handling spaces .
• Diameter: Typically 3.0mm, but custom diameters are available .
• Polish Type: UPC (Ultra Physical Contact) or APC (Angled Physical Contact) for low return loss .
• Performance: Factory-tested for insertion loss, return loss, and end-face quality, ensuring minimal signal degradation .

Applications

• Long-distance single mode networks: Supports distances up to 10 km at 1310 nm wavelength .
• Data centers and telecom backbones: Provides reliable connectivity between switches, routers, and optical distribution frames.
• Enterprise networks: Ideal for connecting patch panels, transceivers, and network devices with mixed connector types.

Advantages

• Low insertion and return loss for high signal integrity .
• Durable construction with ceramic ferrules and high-quality optical fiber .
• Customizable lengths and connector combinations to meet specific network requirements .
• Supports critical network uptime due to reliable performance and factory testing . In summary, ST-SC single mode fiber optic patch cords are essential components for high-performance fiber networks, offering long-distance transmission, low signal loss, and flexible connectivity between devices with ST and SC ports. They are available in various lengths, jacket types, and polish options to suit diverse installation environments .
