Patch Cord Fiber Optic SC

An SC-SC fiber optic patch cord is a short fiber cable with SC connectors on both ends, used to connect networking devices for signal transmission in single-mode or multimode systems.

Overview

SC-SC patch cords are fiber optic cables terminated with SC (Subscriber Connector or Standard Connector) connectors on both ends, designed for reliable and efficient signal routing between devices such as switches, routers, transceivers, and optical distribution frames . They are available in single-mode (OS1, OS2) for long-distance transmission and multimode (OM1, OM2, OM3, OM4) for shorter distances . Patch cords can be simplex (single fiber) or duplex (two fibers for bidirectional communication), depending on network requirements .

Connector Features

• Shape and Mechanism: SC connectors are square-shaped with a 2.5mm ferrule and use a push-pull locking mechanism, making them easy to insert and remove without tools .
• Ferrule Material: Typically made of zirconia ceramic, providing durability, low friction, and precise fiber alignment .
• Polish Types: Available in PC, UPC, or APC polish types, affecting insertion loss and return loss performance .

Technical Specifications

• Insertion Loss: Typically ≤0.2–0.3 dB, ensuring minimal signal attenuation .
• Return Loss: ≥45–60 dB depending on polish type, reducing signal reflection .
• Operating Temperature: -40°C to 75°C, suitable for indoor and controlled environments .
• Bend Tolerance: Can withstand bend angles up to 90° with negligible attenuation, ideal for high-density cabling .

Applications

SC-SC patch cords are widely used in:

• Data centers and server farms for high-density cabling.
• Telecom rooms and enterprise networks for connecting switches, routers, and transceivers.
• GPON, EPON, GBIC, and MADI systems for optical signal distribution.
• 10G/40G/100G Ethernet networks, supporting SFP+ and 10G SR/LRM transceivers .

Advantages

• Robust and user-friendly design for easy installation and maintenance.
• High compatibility with single-mode and multimode fiber systems.
• Space-saving for dense network environments.
• Reliable performance with low insertion and return loss, suitable for high-speed data transmission .

SC-SC fiber optic patch cords are essential for efficient, high-speed optical networking, providing a standardized, durable, and easy-to-use solution for connecting devices in both enterprise and telecom applications.
