The **HFBR-RUS015** is a high-performance Plastic Optical Fiber (POF) cable assembly manufactured by Broadcom (formerly Avago/Agilent). It is specifically designed for short-distance data communications where electromagnetic interference (EMI) immunity and ease of installation are required. --- ## 1. Technical Specifications The HFBR-RUS015 consists of a specific length of cable equipped with connectors. Below are the primary electronic and physical characteristics: | Feature | Specification | | :--- | :--- | | **Fiber Core Material** | Polymethyl Methacrylate (PMMA) | | **Fiber Type** | Step-Index Multimode (1mm core) | | **Connector Type** | Simplex Versatile Link (Gray/Black) | | **Length** | 15 Meters (as indicated by the "015" suffix) | | **Operating Temperature** | -40°C to +85°C | | **Typical Attenuation** | 0.22 dB/m (at 650nm) | | **Minimum Bend Radius** | 25 mm | --- ## 2. Key Components The assembly is comprised of three main electronic/mechanical parts: ### A. The Optical Fiber (POF) The cable uses a 1mm diameter plastic core. Unlike glass fiber, POF is rugged and can be terminated easily without specialized polishing equipment. It is optimized for the **650nm (Red)** visible light spectrum. ### B. Versatile Link Connectors The "Simplex" connectors are designed to plug directly into Broadcom's **Versatile Link** transmitters (e.g., HFBR-1521Z) and receivers (e.g., HFBR-2521Z). * **Friction-fit:** They provide a secure connection without the need for complex latching in many standard applications. * **Non-conductive:** The entire assembly is dielectric, meaning it does not conduct electricity. ### C. Jacket Material The "R" in the part number often signifies a standard **Polyethylene (PE)** jacket, which provides chemical resistance and durability for industrial environments. --- ## 3. Applications and Advantages The HFBR-RUS015 is used primarily in environments where traditional copper wiring fails: * **Industrial Automation:** Connecting Programmable Logic Controllers (PLCs) in high-noise environments. * **High Voltage Isolation:** Since the fiber is plastic, it provides absolute electrical isolation between the transmitter and receiver, protecting equipment from surges. * **EMI/RFI Immunity:** It is immune to electromagnetic interference, making it ideal for use near large motors, transformers, or medical imaging equipment. * **Data Rates:** Supports speeds from DC up to 5 MBd (standard) or higher depending on the specific transceiver used. --- ## 4. Part Number Breakdown Understanding the nomenclature helps in identifying variants: * **HFBR:** Avago/Broadcom Fiber Series. * **R:** Standard POF Cable (Standard Attenuation). * **U:** Unlocked (Simplex) Connector. * **S:** Simplex Cable (Single strand). * **015:** 15-meter length.
