Fiber port SC-SC refers to the use of SC (Subscriber Connector or Standard) at both ends Connector) type connector of fiber optic jumpers. The following is a detailed introduction to the SC-SC fiber optic interface:

　　First, appearance and structure

　　Connector Shape: The SC connector is a rectangular fiber optic connector with a sturdy housing and a push-pull locking mechanism. Its modest size makes it easy to carry and operate in crowded cabinets or panels.

　　End face design: The end face of SC connectors is usually made of precision-ground ceramic or glass materials to ensure accurate docking and low-loss transmission between optical fibers.

　　II. Types and specifications

　　Single-mode SC-SC fiber jumper: suitable for long-distance, high-capacity high-speed data transmission, such as backbone networks and data center internal connections. Commonly used single-mode fiber wavelengths are 1310nm and 1550nm.

　　Multimode SC-SC Fiber Patch Cable: Mainly used for short-range, small bandwidth applications, such as enterprise local area networks. Common wavelengths of multimode fiber are 850nm and 1300nm.

　　III. Application scenarios

　　Data center: SC-SC jumpers play an important role in high-speed interconnection between server clusters, storage area networks (SANs), and network attached storage (NAS).

　　Office LAN: In office buildings, schools, hospitals, and other places, it is used to build internal networks and achieve interconnection of computers, print servers, telephone systems, and other equipment.

　　Telecommunications industry: between carrier-grade equipment, such as optical line end point (OLT), optical network unit (ONU), etc., to achieve fiber access network (FTTx) signaling.

　　Laboratory and educational research: as a transmission medium for optical fiber signals in scientific experiments, teaching demonstrations, and R & D tests.

　　IV. Precautions for use

　　Cleaning and protection: Before each plug-in, use a professional fiber optic cleaning pen or cotton swab dipped in absolute ethanol to clean the end face to avoid signal attenuation caused by dust or impurities.

　　Moderate force: Although the SC connector is designed as a push-pull type, it still needs to be operated gently when plugging and unplugging to avoid damage to the end face due to excessive force.

　　Periodic inspection: Regularly check the status of fiber optic jumpers, and replace products with signs of aging and wear in a timely manner to ensure the stability and transmission efficiency of the network.

　　In summary, SC-SC fiber optic interface has a wide range of application scenarios and an important connection role. When using, it is necessary to follow the correct usage specifications to ensure the stability and transmission efficiency of the fiber optic communication system.
