FC to SC fiber optic patch cord

An FC to SC fiber optic patch cord is a cable with an FC connector on one end and an SC connector on the other, used to link fiber optic equipment with secure, low-loss connections.Overview

FC (Ferrule Connector) and SC (Subscriber Connector) are two common fiber optic connector types. The FC connector is a screw-on metal connector designed for high vibration resistance and secure connections, often used in industrial or high-precision applications. The SC connector features a push-pull snap-in design, making it easy to install and ideal for telecom, FTTH, and enterprise networks . An FC-to-SC patch cord allows devices with different connector types to interface seamlessly.

Fiber Types and Specifications

• Single-mode (SM) fiber: Typically 9/125 µm, suitable for long-distance, high-speed networks. Available with PC, UPC, or APC polish types for low insertion loss and reduced back reflection .
• Multimode (MM) fiber: Commonly 50/125 µm or 62.5/125 µm, used for short-distance data networks and LANs. OM3 laser-optimized versions are available for higher bandwidth applications .
• Cable diameters: Options include 0.9 mm, 1.8 mm, 2 mm, or 3 mm outer jackets, with LSZH, Plenum, or Rizer-rated types for indoor or industrial use .

Connector and Patch Cord Variants

• Simplex: Single fiber strand, used for one-way signal transmission.
• Duplex: Two fiber strands side by side, often used for bidirectional communication .
• Polish types:
  • PC (Physical Contact): Standard low-loss connection.
  • UPC (Ultra Physical Contact): Enhanced low-loss, minimal back reflection.
  • APC (Angled Physical Contact): Angled end face for high-performance applications with very low back reflection .

Applications

FC-to-SC patch cords are widely used in:

• Data centers and server rooms for connecting transceivers and patch panels.
• Telecom and FTTH networks for linking optical equipment.
• Industrial and laboratory environments requiring secure, vibration-resistant connections .

Key Considerations

• Compatibility: Ensure the patch cord matches the fiber type (SM or MM) and connector polish type of your equipment.
• Length and routing: Standard lengths are 1–10 meters, but custom lengths are available to maintain neat cable management.
• Insertion loss: High-quality FC-to-SC cords provide low insertion loss and reliable signal transmission. FC-to-SC fiber optic patch cords provide a versatile solution for connecting devices with different connector types, combining the secure screw-on FC interface with the convenient SC push-pull design, suitable for both single-mode and multimode networks .
