The Simplex patch cable 151P7EAJA30E from Btr Blumberger is a specialized fiber optic cable designed for FITH applications, i.e., for connecting a fiber optic wall socket to an end device within fiber network environments. It is based on a singlemode fiber of type OS2 with a core diameter of 9 µm and a cladding diameter of 125 µm (E9/125). The cable is designed for use in modern, high-performance networks, particularly in environments requiring high bandwidth and low signal loss.

Applications
This cable is specifically designed for FITH applications (Fiber to the Home), where a stable and reliable fiber optic connection is required from the outdoor wall socket to the end device inside the home. It is also suitable for other applications in telecommunications and data transmission where high mechanical robustness and bend insensitivity are required. Use in indoor and outdoor environments is possible, as the cable features high mechanical load capacity and is suitable for use in structured cabling systems.

Functions and Equipment in Detail
The patch cable is configured as a simplex cable, meaning it contains only one fiber strand and is therefore designed for unidirectional data transmission. It is bend-insensitive according to standards IEC 60793-2-50 Type B6_a and B6_b as well as G.657.A2 and B2, enabling high flexibility during installation and routing. Compatibility with G.652.D ensures broad applicability in existing network infrastructures. The cable is equipped with a halogen-free, low-smoke, fire-retardant jacket (LSHF-FR), which increases safety in case of fire and allows use in enclosed spaces or buildings with high safety requirements.

Technology Explained Simply
The singlemode fiber OS2 used is optimized for light signal transmission over long distances, where the small core size (9 µm) enables high bandwidth and minimal signal distortion. Bend insensitivity according to G.657.A2 and B2 means the cable functions without significant signal loss (insertion loss) or return loss, even when bent tightly. This is particularly important during installation in confined spaces or when routing through cable ducts. The outer diameter of 2.8 mm ensures good handling and mechanical stability. The cable jacket is white, which facilitates easy identification in cable management.

Compatibility and Accessories
The cable is designed for use with standard connectors in SC-S APC and LC-S APC formats, enabling universal connection to common network devices and fiber optic wall sockets. Compatibility with G.652.D ensures interoperability with existing fiber optic infrastructures. Use in FITH applications often requires connecting the outdoor wall socket to an end device inside the home, for which this cable is specifically designed. The cable configurator function allows adaptation to specific requirements, with all available variants being created through this configurator.

Installation and Mounting
Installation is performed by simply plugging the connectors into the corresponding ports. The cable’s bend insensitivity facilitates routing, especially in tight or curved pathways. The use of halogen-free, low-smoke, fire-retardant jacket material requires no special precautions during installation, although routing should comply with applicable standards and regulations. The cables are marked with a serial number, enabling unique identification and documentation.

Operational Advantages
The cable offers high reliability and stability in data transmission, even under demanding mechanical conditions. 100 % testing for insertion and return loss ensures consistent performance and minimal signal loss. The use of LSHF-FR materials increases safety in case of fire, and bend insensitivity reduces the risk of breaks or signal loss during installation. The white color facilitates identification in cable management, and the serial number enables precise documentation and maintenance.
