LSF vs LSZH Cable: What's the Difference?
Updated at May 11th 20241 min read
Solid and comprehensive defenses against potential catastrophes, such as natural disasters, flooding, water leaks, or fire, are necessary for residential and commercial buildings. Building structures are designed with specific equipment and materials to prevent excessive damage and ensure people's safety.
One possible occurrence is a fire. Suppose a fire breaks out in a structure. In that case, many precautions are taken to safeguard people, including using LSF or LSZH cables. In this article, we shall discuss the functions of both wires, along with some differences.
What are LSF Cables?
LSF, short for Low Smoke and Fume, refers to a type of cable designed with materials that emit minimal smoke and fumes when exposed to fire. These cables typically contain a reduced amount of halogen elements, which are known for their potential toxicity when burned. Commonly used in various applications, LSF cables offer a balance between fire resistance and environmental considerations.
What are LSZH Cables?
LSZH, short for Low Smoke Zero Halogen, denotes a type of cable engineered with materials that produce limited smoke and do not emit halogen compounds when exposed to fire. LSZH Ethernet cables are designed to minimize the release of toxic gases and halogenated compounds, reducing health and environmental hazards during combustion.

Differences Between LSF and LSZH Cables
Although LSF cables and LSZH cables share similarities in some aspects, their subtle differences can have significant implications. While their characteristics may not diverge drastically, one type of cable's advantages are unmistakable. Here's a comparison that covers their security level, environmental impact, and cost:
LSF Cables | LSZH Cables | |
Safety | Higher risk due to more toxic gases and denser smoke when burned | Safer with less poisonous gases and smoke emitted in a fire |
Environmental Impact | Higher ecological impact due to more pollutants released when burned | Lower impact with reduced emissions of halogenated compounds |
Cost | Lower-cost option when compared to LSZH cables | More expensive due to higher safety performance |
Understanding these differences is crucial for selecting the most suitable cable type based on safety, regulatory, and environmental considerations.
Application Scenarios of LSF and LSZH Cables
Having understood the distinctions between LSF and LSZH cables, it's essential to consider their practical applications across various industries and environments. LSF and LSZH cables cater to distinct application scenarios based on their unique properties and characteristics.
LSF Cables
LSF cables are commonly employed in environments where reducing smoke and fume emissions is critical, including:
Residential buildings
Small offices
Environments with lower safety requirements
LSZH Cables
LSZH network cables, being halogen-free, are preferred in settings where stringent safety regulations or heightened environmental concerns prevail, including:
Commercial edifices
Data centers
Public areas (e.g., malls, airports, train stations)
Aerospace industry
Underground transportation systems
In environments where reducing smoke and fume emissions is critical, LSF cables are often the choice. However, for settings with stringent safety regulations or heightened environmental concerns, FS's LSZH cables are the preferred option. For instance, in commercial edifices, data centers, and public areas, using FS's LSZH cables ensures a safer environment with fewer toxic gas emissions, even in a fire.
Conclusion
Choosing LSF and LSZH cables impacts building safety and environmental concerns. LSF cables are suitable for environments with lower safety requirements, while LSZH cables are preferred in settings where high safety standards and environmental considerations are crucial. This understanding aids in optimal selection for safety and regulatory compliance in building infrastructure.
