Understanding the differences—such as plenum and riser ratings in the U.S. or LSZH jackets in Europe—ensures that the right cables are used for the correct application, minimizing hazards and improving efficiency.

2. What is a Fiber Optic Patch Cord?

A fiber optic patch cord (or latiguillo de fibra óptica in Spanish, LWL-Patchkabel in German, cordone ottico in Italian, and jarretière optique in French) is a length of optical fiber cable with connectors attached at both ends. These cords connect different optical network components, such as transceivers, switches, routers, or patch panels, ensuring stable data transmission over optical fiber.

The cables can be either single-mode or multimode, depending on the application's requirements:

  • Single-mode cables feature a smaller core (typically 9 µm) and are designed for long-distance data transmission, often used in telecommunications and metropolitan area networks (MANs).
  • Multimode cables, available in OM1, OM2, OM3, OM4, and OM5 varieties, have larger cores (50-62.5 µm) and are used for shorter-distance, high-bandwidth connections, such as in data centers and enterprise networks.

3. Key Features of Fiber Optic Patch Cords

All fiber optic patch cords share certain essential features, regardless of the market. However, regional terminologies and technical preferences shape how these features are prioritized:

  • Core Size: Single-mode cables (9 µm) vs. multimode cables (50/62.5 µm).
  • Connector Types: LC (Lucent Connector), SC (Standard Connector), ST (Straight Tip), and MPO (Multi-fiber Push On) connectors are commonly used. Regional markets, such as the U.S., favor LC and MPO for data centers, while SC and ST are more popular in legacy systems.
  • Jacket Materials: The outer jacket is crucial for determining the cable’s fire rating and environmental resistance. In the U.S., plenum-rated jackets are used in air-handling spaces, whereas riser-rated jackets are used for vertical installations. In Europe, LSZH (Low Smoke Zero Halogen) jackets are preferred due to stricter fire and environmental safety standards.

4. Fire Ratings and Cable Jackets Across Markets

The materials used in the outer jackets of fiber optic patch cords vary based on the region and local fire safety regulations. Different countries have unique safety standards that impact cable jacket material and the environments where they are installed.

U.S. Market: Plenum and Riser Ratings

In the United States, fire safety standards are stringent, especially in commercial buildings and data centers. Two primary ratings apply:

  • Plenum-rated cables must be used in spaces that facilitate air circulation, such as air ducts or drop ceilings. These cables are made from flame-resistant materials that minimize toxic smoke in the event of a fire.
  • Riser-rated cables are used for vertical cable runs, such as between floors. They are designed to resist the spread of flames in non-plenum environments.

European Market: LSZH Jackets

Across Europe, LSZH (Low Smoke Zero Halogen) cables are the standard. These cables emit very little smoke and no toxic halogens when burned, making them ideal for use in public buildings where safety is paramount. This preference is consistent in markets like Spain (Latiguillo de Fibra Óptica), Italy (Cordone Ottico), and France (Jarretière Optique).
