A fiber optic patch cable is a short optical fiber cable used to connect two network devices, such as switches, routers, and optical transceivers. Unlike traditional copper cables, fiber optic patch cables use strands of glass or plastic to carry light signals, which significantly reduces interference and allows for high-speed data transmission over long distances.
Types of Fiber Optic Patch Cables
When choosing a fiber optic patch cable, it's important to understand the different types available, as they serve different functions in a network. Here are the key types:
1. Single Mode (SM) Fiber Patch Cable
- Core Size: 9μm
- Application: Ideal for long-distance data transmission, typically used in telecommunications and large-scale network setups.
- Fiber Type: OS1 or OS2.
- Advantages: Low attenuation, high bandwidth, suitable for long-distance communication (up to 10 km or more).
2. Multimode (MM) Fiber Patch Cable
- Core Size: 50μm or 62.5μm
- Application: Used for short-distance communication, common in local area networks (LAN) and data centers.
- Fiber Type: OM1, OM2, OM3, or OM4.
- Advantages: Cost-effective, easier to install, and ideal for short-range applications (typically up to 550 meters).
Connector Types
Fiber optic patch cables come with various types of connectors at the ends, depending on the network equipment being connected. The most common connector types include:
- LC (Lucent Connector): Small form factor, commonly used in data centers and telecommunications.
- SC (Subscriber Connector): Widely used in telecom and network applications.
- ST (Straight Tip): Mostly used in older networks and military applications.
- FC (Ferrule Connector): Ideal for high-vibration environments due to its threaded body design.
