• Art: Kabel
• Länge: 25 m

Experience unparalleled signal integrity and robust performance with the 25m BNC/SDI Cable Reel, engineered for demanding professional audio and video environments. This high-quality cable solution ensures reliable transmission of critical signals over extended distances, making it an indispensable tool for live broadcasts, studio setups, events, and permanent installations. Designed with precision and built for durability, it delivers crystal-clear video and pristine audio without compromise, providing the backbone for seamless content delivery in any high-stakes production scenario. Its practical reel design facilitates easy deployment and retraction, offering both convenience and protection for the cable, thereby extending its operational lifespan.

SIGNAL INTEGRITY AND TRANSMISSION
This 25-meter BNC/SDI cable is specifically optimized for transmitting Serial Digital Interface (SDI) signals, supporting various formats from standard definition (SD-SDI) to high definition (HD-SDI) and potentially 3G-SDI, depending on specific cable specifications. Its core design prioritizes minimal signal attenuation and maximum interference rejection, crucial for maintaining picture quality and audio fidelity over its considerable length. The impedance matching is precisely controlled to 75 Ohms, which is standard for video applications, ensuring that reflections are minimized and the signal reaches its destination with optimal clarity.

CABLE CONSTRUCTION AND MATERIALS
The robust construction of this cable reel is tailored for longevity and consistent performance. The cable itself features a high-quality coaxial conductor, typically made of oxygen-free copper, which ensures superior conductivity and corrosion resistance. The dielectric insulation material is chosen for its excellent electrical properties, maintaining consistent impedance and reducing signal loss. Shielding is comprehensive, often comprising a braided copper shield combined with an aluminum foil layer, effectively protecting the signal from electromagnetic interference (EMI) and radio frequency interference (RFI) that can degrade video and audio quality in complex environments. The outer jacket is made from durable PVC or a similar resilient compound, offering significant protection against abrasion, kinking, and environmental factors such as temperature fluctuations and moisture.

CONNECTORS AND TERMINATION
The cable is terminated with high-grade BNC connectors, renowned for their secure locking mechanism and reliable connection. These connectors are precision-machined to ensure a perfect 75-Ohm impedance match throughout the connection point, which is critical for high-frequency SDI signals. The crimping or soldering process for attaching the connectors is executed with meticulous attention to detail, preventing signal leakage and ensuring a robust physical connection that can withstand repeated plugging and unplugging cycles without degradation.

REEL DESIGN AND PRACTICALITY
The integrated cable reel design significantly enhances the product's usability and protection. The robust reel frame, often constructed from durable plastic or metal, provides a stable platform for storage and deployment. An integrated winding handle allows for quick and effortless retraction of the cable, preventing tangles and kinks that can damage the internal conductors and shielding. Some reels include a braking mechanism to prevent unwanted unwinding, and most feature a sturdy base for stability during operation. This design not only prolongs the life of the cable by protecting it from environmental damage and physical stress but also simplifies transportation and setup, making it an ideal choice for mobile productions or temporary installations.

APPLICATIONS AND VERSATILITY
This 25m BNC/SDI cable reel is exceptionally versatile and finds its application across a wide array of professional AV scenarios. It is perfectly suited for broadcasting studios, outside broadcast (OB) vans, live event productions, corporate presentations, educational facilities, and surveillance systems. Its robust design makes it suitable for both indoor and outdoor use, offering a dependable solution wherever long-distance, high-quality digital video transmission is required. Whether connecting cameras to switchers, monitors to distribution amplifiers, or routing signals across a control room, this cable reel provides the necessary reliability and performance.

CLASSIFICATION
This product falls under the classification of professional audio/video infrastructure components, specifically within the sub-category of digital video signal transmission cables and accessories. As a BNC/SDI cable reel, it is an essential tool for broadcast, media production, and AV integration professionals who require reliable, high-performance connectivity for Serial Digital Interface (SDI) signals. Its primary function is to facilitate the secure and high-fidelity transmission of digital video, and potentially embedded audio, over moderate to long distances. The integrated reel system elevates it beyond a mere bulk cable, classifying it as a deployable and manageable field solution, indispensable for environments demanding quick setup, breakdown, and protected storage. It is distinct from passive consumer cables due to its specific impedance matching (75 Ohm), robust construction for professional environments, and its suitability for standardized digital video formats like SD-SDI, HD-SDI, and 3G-SDI, marking it as a critical element in any professional digital video workflow.
