The Belden 1885ENH GELB is a Cat7 installation cable, specifically designed for use in structured cabling systems. It is an S/FTP cable with shielding consisting of pair and overall shielding, designed for high data transfer rates and reliable signal transmission in demanding environments. The cable is available in yellow color and is supplied in a length of 100 meters per carton. It is intended for indoor use and complies with requirements for flame-retardant, low-smoke, and low-oxygen combustion materials (FRNC/LSOH), making it suitable for use in buildings with enhanced safety requirements.

Applications

The cable is designed for use in modern network infrastructures, particularly in environments requiring high bandwidth and low signal interference. Typical applications include office buildings, data centers, industrial facilities, and other environments where stable and fast data transmission over long distances is required. The Cat7 category enables data transfer rates up to 10 Gbit/s over a distance of up to 100 meters, with a maximum frequency of 1000 MHz ensuring high signal integrity.

Functions and Equipment in Detail

The cable consists of four pairs with an AWG23 cross-section size, each pair individually shielded (S/FTP). The overall shielding provides additional protection against electromagnetic interference (EMI) and enables reliable data transmission even in interference-prone environments. The yellow color serves as visual identification and facilitates easy recognition within the cabling system. The use of FRNC/LSOH materials ensures that in case of fire, only minimal smoke and no toxic gases are released, enhancing building safety.

Technology Explained Simply

The designation S/FTP describes the shielding type: “S” stands for Screen (overall shielding), “FTP” for Foil Twisted Pair (shielded pairs). This construction minimizes electromagnetic interference between individual wire pairs (crosstalk) and protects the cable from external disturbances. The frequency of 1000 MHz enables high bandwidth, sufficient for future network requirements such as Gigabit and 10-Gigabit Ethernet. The AWG23 cross-section size corresponds to a diameter of approximately 0.57 mm, offering a good balance between flexibility and conductivity.

Compatibility and Accessories

The cable is compatible with various accessories required for installation and connection. These include, for example, Cat6A RJ45 connectors suitable for field termination, as well as modular jacks such as the 130B11-Z Cat.6A 180° Jack. Connection modules such as the LSA+ connection module CAT7A or cable connectors of class EA Cat.6A 180 can also be used to integrate the cable into existing infrastructures. The use of appropriate connectors is essential to fully utilize the performance of Cat7 cabling.

Installation and Mounting

Installation is typically carried out by specialists in structured cabling. The cable is intended for indoor installation and can be routed in cable ducts, wall coverings, or ceiling constructions. The use of a cable stripper such as the Jokari PC-STRIPE cable stripper for 5.5–15 mm facilitates precise processing of the cable jacket. Termination is done by crimping RJ45 connectors, ensuring correct polarity (T568A or T568B). Cable connections should be made in accordance with applicable standards for structured cabling to ensure optimal signal quality.

Operational Advantages

The cable offers high signal integrity and low interference, resulting in a stable and reliable network connection. The use of FRNC/LSOH materials increases fire safety, which is required in many buildings. The high frequency of 1000 MHz enables future-proof usage, even if network bandwidth requirements increase. The yellow color simplifies identification in the cabling network, making maintenance and fault diagnosis easier. The cable construction is designed for long service life, ensuring long-term return on investment in cabling infrastructure.
