The **L4AS-262-R** is a specific type of RF (Radio Frequency) component, primarily used in telecommunications infrastructure. Specifically, it is a **high-performance jumper cable assembly** manufactured by CommScope (Andrew brand). Below is a detailed breakdown of its electronic and mechanical specifications. --- ### 1. General Overview The L4AS-262-R is part of the **SureFlex® Premium** line. It is a factory-molded jumper assembly designed to connect main feeder cables to antennas or remote radio units (RRUs). | Feature | Specification | | :--- | :--- | | **Product Type** | SureFlex® Premium, static PIM | | **Cable Family** | LDF4-50A (1/2 in Foam Coaxial) | | **Connector A** | 7-16 DIN Male | | **Connector B** | 4.3-10 Male | | **Body Style** | Straight (Both ends) | --- ### 2. Electronic Specifications These parts are engineered to minimize signal loss and interference in high-frequency environments (LTE, 5G, CBRS). | Parameter | Value / Range | | :--- | :--- | | **Impedance** | 50 Ohm | | **Operating Frequency Band** | 698 – 2700 MHz (Commonly used up to 6GHz) | | **VSWR / Return Loss** | 1.065:1 / 30 dB (at 698–2700 MHz) | | **Passive Intermodulation (PIM)** | -117 dBm (Minimum) / -162 dBc | | **DTF (Distance to Fault)** | Verified via Pulse Testing | --- ### 3. Physical & Material Construction The "electronic" performance of the cable is heavily dependent on its material composition to prevent oxidation and signal leakage. * **Jacket Material:** Black PE (Polyethylene) or LSZH (Low Smoke Zero Halogen) depending on specific sub-variant. * **Dielectric:** Foam Polyethylene (provides low attenuation). * **Inner Conductor:** Copper-clad aluminum wire. * **Outer Conductor:** Corrugated copper. * **Weatherproofing:** The "-R" often denotes a specific weatherproofing boot or a revised RoHS compliance standard, ensuring the connection remains moisture-sealed (IP68 rating). --- ### 4. Key Features * **Molded Boot:** The connectors are factory-molded onto the cable. This prevents cable "pull-out" and ensures a consistent 360-degree contact for superior PIM performance. * **Flexibility:** While the 1/2" cable is rigid compared to standard ethernet, the "SureFlex" technology allows for a smaller bend radius without damaging the internal copper shielding. * **4.3-10 Connector:** This connector is smaller than the traditional 7-16 DIN, designed to handle high power while being much more resistant to PIM (Passive Intermodulation) caused by loose connections. --- ### Summary of Usage You will typically find the **L4AS-262-R** in: 1. **Macro Cell Sites:** Connecting the base station to the antenna. 2. **Small Cells:** Providing the final link in high-density urban 5G deployments. 3. **DAS (Distributed Antenna Systems):** In-building wireless coverage for stadiums or airports.
