The BELDEN 1855A Datasheet is a crucial resource for anyone working with high-performance video and audio transmission. It provides detailed specifications and performance characteristics of the BELDEN 1855A coaxial cable, enabling engineers and technicians to make informed decisions regarding its use in various applications. Understanding the nuances within the BELDEN 1855A Datasheet is key to ensuring optimal signal quality and system reliability.
Understanding the BELDEN 1855A Datasheet A Technical Overview
The BELDEN 1855A Datasheet is more than just a list of numbers; it’s a comprehensive guide to understanding the cable’s construction, electrical properties, and performance capabilities. It details the cable’s physical attributes, such as its diameter, weight, and materials used in its construction (like the type of conductor and insulation). It also specifies the cable’s electrical characteristics, including impedance, capacitance, and attenuation at various frequencies. This information is paramount for designing and implementing systems where signal integrity is critical. For example, knowing the cable’s attenuation allows engineers to calculate the maximum cable length before signal loss becomes unacceptable.
The datasheet also outlines the cable’s compliance with industry standards and certifications. These standards might include certifications for flame resistance, RoHS compliance (Restriction of Hazardous Substances), and other relevant regulations. The 1855A is commonly used in broadcast and professional video environments due to its low loss and excellent shielding properties. Here are some common applications:
- HD-SDI Video Transmission
- Broadcast Facilities
- Studio Interconnections
- Digital Audio Applications
Furthermore, the BELDEN 1855A Datasheet will often include performance graphs and charts that illustrate the cable’s behavior under different conditions. These graphs can show how attenuation varies with frequency or how return loss is affected by cable length. This type of data is invaluable for predicting the cable’s performance in real-world scenarios and troubleshooting potential issues. A common table in the datasheet often looks something like this (simplified):
| Frequency (MHz) | Attenuation (dB/100ft) |
|---|---|
| 1 | 0.4 |
| 1000 | 7.2 |
| 3000 | 13.1 |
