A pair of fiber optic patch cords

A pair of fiber optic patch cords consists of two pre-terminated fiber cables used to connect network devices or infrastructure, available in various fiber types, connector types, and lengths.

Overview

A fiber optic patch cord (also called a fiber jumper) is a cable with fiber optic connectors at both ends, designed to connect devices such as switches, routers, servers, or fiber transceivers, or to link into fiber optic infrastructure cabling . A pair typically includes two cords, allowing bidirectional communication or redundancy in a network setup.

Fiber Types

Patch cords are available in single-mode (SM) and multimode (MM) fibers:

• Single-mode (OS1/OS2): Ideal for long-distance transmission and high-speed networks .
• Multimode (OM1, OM2, OM3, OM4, OM5): Suitable for shorter distances, data centers, and LANs .
• Bend-insensitive fibers (G.657A1/A2): Useful for tight spaces and FTTH applications .

Connector Types

Common connectors include:

• LC, SC, ST, FC: Standard connectors for most networking equipment .
• MTP/MPO, E-2000, MU, MDC, Uniboot LC: High-density or specialized applications .
• Duplex or simplex: Duplex cords have two fibers for simultaneous transmit and receive; simplex has one fiber .

Cable Features

• Jacket material: Options include LSZH, FRNC, or plenum-rated for indoor or outdoor use .
• Kevlar/aramid strength members: Provide durability and protection against handling stress .
• Low insertion loss and return loss: Ensures high-quality signal transmission .
• Customizable lengths and colors: Helps with network organization and identification .

Applications

• Connecting IT hardware point-to-point (switch-to-switch, server-to-switch)
• Linking to fiber optic infrastructure in data centers or buildings
• Cable TV, communication networks, and fiber optic testing equipment

Purchasing Options

You can buy a pair of fiber optic patch cords from suppliers like EFB-Elektronik, Corning, ZION Communication, UnitekFiber, and Rosenberger, which offer standard and custom assemblies, fast delivery, and expert advice . Many suppliers provide factory-terminated cords with various connector types, fiber modes, and jacket materials to match your network requirements. In summary, a pair of fiber optic patch cords is a versatile and essential component for connecting fiber optic devices, available in multiple configurations to suit distance, speed, and environmental needs. Choosing the right fiber type, connector, and jacket ensures optimal network performance and reliability.
