Flat-head fiber optic patch cord

A fiber optic patch cord with a flat head is a pre-terminated cable designed to connect fiber optic devices using flat-faced connectors, ensuring low-loss, high-performance signal transmission.

Overview

A fiber optic patch cord, also called a fiber jumper, is a short cable with connectors on both ends used to link devices in a fiber optic network. The flat head refers to the physical design of the connector end, typically with a flat or physical contact (PC) polish, which ensures minimal signal reflection and low insertion loss during transmission .

Connector Types

Flat head patch cords are available in various connector types to suit different applications:

• LC (Lucent Connector): Small form factor, commonly used in high-density racks.
• SC (Subscriber Connector): Larger, push-pull design, widely used in telecom and data centers.
• ST (Straight Tip): Bayonet-style connector, often used in legacy networks.
• MTP/MPO: Multi-fiber connectors for high-speed, high-density applications .

Fiber Types

Patch cords can be made with different fiber types depending on the network requirements:

• Single-mode (OS1/OS2): For long-distance, high-bandwidth applications.
• Multimode (OM1, OM2, OM3, OM4, OM5): For shorter distances, often in data centers or LANs.
• Bend-insensitive fibers (G.657A1/A2): Ideal for tight spaces and FTTH installations .

Key Features

• Low insertion loss and return loss: Ensures high-quality signal transmission.
• Flexibility: Easy to route between devices or racks.
• Durability: Kevlar yarn or aramid fibers inside the jacket provide strength and protection.
• Customizable: Length, jacket color, and connector type can be tailored to project requirements .

Applications

Flat head fiber optic patch cords are used in:

• Connecting switches, routers, and patch panels in data centers.
• Linking optical network terminals (ONTs) in FTTH deployments.
• Splicing or connecting fiber optic installation cables in telecom networks .

Purchasing

High-quality flat head patch cords are available from suppliers like EFB-Elektronik, FS Europe, and Corning, offering pre-tested, low-loss cables with various connector options and custom lengths . Many suppliers provide fast delivery and customization to meet specific network standards. In summary, a fiber optic patch cord with a flat head is a versatile, reliable solution for connecting fiber optic devices, available in multiple connector types and fiber specifications to suit both short- and long-distance applications.
