The Siemens Indoor Fiber Optic Cable, type 6XV1820-7BN15, is a pre-assembled glass fiber optic indoor cable for use in industrial automation systems. It is specifically designed for indoor applications and serves data transmission via fiber optic (FO) in networks of the SIMATIC NET series. The cable has a length of 15 meters and is equipped with four BFOC connectors, enabling secure and reliable connections to corresponding network devices.

Applications
This FO cable is designed for use in industrial environments where high data integrity and low interference susceptibility are required. It is particularly suitable for applications in automation technology, where fiber optic cables are preferred due to their high bandwidth and immunity to electromagnetic interference. The foot-resistant and flame-retardant design also makes it suitable for areas with mechanical stress or increased fire safety requirements.

Functions and Equipment in Detail
The cable is configured as multimode fiber optic (MM), with a core diameter of 62.5 µm and a cladding diameter of 125 µm, corresponding to the OM1 standard category. This configuration enables efficient data transmission over medium distances within factories or building complexes. The use of glass as the transmission medium ensures high signal quality and low attenuation. The cable is halogen-free, meaning that no toxic halogen compounds are released in case of fire, thereby increasing safety in the operational environment.

Technology Explained Simply
The term BFOC (Bayonet Fibre Optic Connector) describes the connector type, which uses a twist-and-lock mechanism to enable secure and quick connections. The four BFOC connectors at both ends of the 15-meter cable allow direct connection to compatible network devices, such as switches or industrial routers. The foot-resistant construction protects the sensitive fiber optic cable from mechanical damage, especially in areas with frequent foot traffic. The flame-retardant design meets fire safety requirements in industrial facilities.

Compatibility and Accessories
The cable is part of the SIMATIC NET system and compatible with other components of this series. Suitable accessories offered in the product line include, for example, the BFOC connector set 6GK1901-0DA20-0AA0 (pack of 20) and the MM FO LC Duplex connector 6GK1901-0RB10-2AB0 (pack of 10). These components can be used for extending or maintaining existing FO networks. The use of standard connectors ensures easy integration into existing infrastructures.

Installation and Mounting
The pre-assembled cable is already fitted with the required connectors and can be directly integrated into the network. Installation is performed by simply plugging the BFOC connectors into the corresponding ports of the network devices. The foot-resistant jacket facilitates installation in areas with high mechanical stress, such as production halls or corridors. No additional tools or special mounting procedures are required.

Operational Advantages
The use of a halogen-free, flame-retardant, and foot-resistant FO cable increases the safety and reliability of the network. Fiber optic transmission offers high bandwidth and is immune to electromagnetic interference, ensuring data integrity in industrial environments. The pre-assembled length of 15 meters with pre-mounted connectors reduces installation time and minimizes error sources during cabling.
