securityNET S/FTP Category 7A LSZH Dca cable 500m

Cables designed for indoor installations are engineered to operate in stable environmental conditions typical of residential, office, and infrastructure buildings. Their construction, based on conductors made of 100% pure solid copper, ensures stable and consistent transmission performance along the entire cable length. The use of solid copper minimizes signal loss and supports compliance with the requirements of ICT systems. These cables are fully compatible with solutions used in structured cabling systems.

Category 7A, corresponding to Class FA, was developed for highly demanding network installations. This standard supports data transmission speeds of up to 10 Gb/s while providing a very high level of immunity to electromagnetic interference.
According to the standard, Class FA cabling operates at frequencies of up to 1,200 MHz, ensuring excellent signal stability and precise transmission performance.

This solution is widely used in advanced LAN networks, industrial environments, and IP CCTV monitoring systems. Category 7 cable is designed for connecting network devices such as switches, servers, and IP cameras. To maintain the declared performance parameters, the maximum length of a single transmission channel should not exceed 90 meters.

The LSZH (Low Smoke Zero Halogen) sheath used in twisted pair cables is designed to provide enhanced fire safety. This material contains no halogens and, when exposed to high temperatures, emits minimal smoke without producing aggressive corrosive gases.

LSZH-sheathed cables are intended for indoor installations in environments with elevated safety requirements, such as public buildings, offices, data centers, and evacuation routes. Compared to PVC, the sheath is generally less flexible, but it provides better protection for people, infrastructure, and equipment in emergency situations.

Dca-class cables meet the requirements for limited contribution to fire development. This classification is based on test results in accordance with EN 50399 and EN 60332-1-2 standards, including the measurement of heat release and flame spread under bundled cable installation conditions.

The full class designation should include additional parameters: smoke production (s1, s2, s3), flaming droplets (d0, d1, d2), and the acidity of combustion gases (a1, a2, a3). Dca cables are subject to the AVCP 3 assessment system, which requires initial type testing carried out by an accredited laboratory.

Cables of this class are used in standard commercial and residential buildings where no elevated fire safety requirements apply. In some EU countries, the Dca class represents the minimum required level for permanent building installations.

The PoE++ Type 4 standard, compliant with IEEE 802.3bt, enables power delivery to network devices with up to 90 W while simultaneously transmitting data. Power is supplied using all four wire pairs (4PPoE), allowing support for high-power devices without additional power sources. The maximum transmission channel length is up to 100 meters.

PoE++ Type 4 is used to power advanced Wi-Fi access points, high-power CCTV cameras including PTZ and heated models, access control systems, information kiosks, multimedia terminals, Video VoIP devices, and other active equipment requiring approximately 71–90 W of power, depending on the power class.

Cable supplied on a standard 500 m reel. This packaging format is intended for larger installations, enabling efficient deployment of longer cable runs.
