Fiber Cable Patch Cord: Understanding Its Types and Applications

Exploring Types, Applications, and Benefits of Fiber Optic Patch Cords

Fiber cable patch cords, also known as fiber optic patch cables or fiber connectors, are essential components in optical communication systems. They enable the connection of optical devices, such as optical transceivers, switches, and routers, to fiber optic cables. This article aims to provide a comprehensive guide to fiber cable patch cords, including their types, applications, and benefits.

Types of Fiber Cable Patch Cords

1. Single-Mode and Multi-Mode Patch Cords

• Single-Mode Patch Cords: Typically indicated by yellow color, single-mode patch cords have a smaller core diameter (8μm to 10μm) and are capable of transmitting light over long distances, up to 10 kilometers. They are ideal for long-haul and high-speed applications.

• Multi-Mode Patch Cords: Often indicated by orange or gray color, multi-mode patch cords have a larger core diameter (50μm to 65μm) and are suitable for shorter distances, typically up to 300 meters or 500 meters depending on the laser source. They are commonly used in local area networks (LANs).

2. Connector Types

Fiber cable patch cords come with various connector types, each designed for specific applications and environments. The most common connector types include:

• FC Connector: Known for its metal housing and threaded coupling, the FC connector provides a secure and stable connection. It is often used in storage area networks (SANs).

• SC Connector: Featuring a plastic housing and push-pull coupling, the SC connector is easy to install and remove. It is widely used in telecommunications and data centers.

• ST Connector: With a metal housing and bayonet coupling, the ST connector is robust and suitable for high-vibration environments. It is commonly found in fiber distribution frames.

• LC Connector: The LC connector, which stands for Lucent Connector, is similar to the SC connector but smaller in size. It is ideal for high-density applications and is often used in networking equipment.

Additionally, MPO (Multi-fiber Push-On) connectors are used for high-density fiber optic cabling, particularly in data centers supporting high-speed Ethernet applications such as 40G and 100G.

3. Fiber Grades for Multi-Mode Patch Cordswww.adsscable.cn

Multi-mode fiber patch cords are classified into different grades based on their optical performance, including OM1, OM2, OM3, OM4, and OM5.

• OM1 and OM2: These grades support shorter distances for 10 Gb Ethernet and are commonly used in 1 Gb Ethernet applications.

• OM3 and OM4: Optimized for laser-based equipment, OM3 and OM4 grades support longer distances for 10 Gb Ethernet and are often used in data center environments.

• OM5: The latest grade, OM5, offers enhanced bandwidth and supports wavelength division multiplexing (WDM), making it ideal for future high-speed applications such as 200G and 400G Ethernet.
