ANSI SCTE 244-2018 pdf download.Specification for Braided 75 Ω, Micro-Series Quad Shield Coaxial Cable for Connectivity and Dense CCAP/Edge QAM Applications
1.2. Scope
1.2.1. This specification defines the required performance with regards to electrical and mechanical properties of 75-ohm, braided micro-series quad shield coaxial cable for connectivity and dense CCAP/Edge QAM applications.
1.2.2. These cables are used in the transmission of RF signals and power for voice, data and video applications.
1.2.3. Cables meeting the requirements within this standard are for use with interior applications. Use within exterior applications is outside the scope and requirements of this document.
1.3. Benefits
Specification for Braided 75 Ω Micro-Series Quad Shield Coaxial Cable for Connectivity and Dense CCAP/Edge QAM Applications, is provided to ensure accurate and consistent micro-series coax for high density applications in today’s broadband applications. As fiber is deployed deeper into the system, and with Remote PHY technologies, the need for even smaller coax assemblies is realized. This specification is a logical step to ensure the interoperability and performance for these cables and assemblies, the customer demands.
1.4. Intended Audience
The intended audience for this specification are manufacturers, evaluation laboratories, and end-users with proper laboratories and equipment to perform this test described therein.

5. Definitions attenuation
The decrease in magnitude of a wave as it travels through any transmitting medium, such as cable or circuitry. It is the difference between transmitted and received power. coaxial cable A type of cable used for broadband data and cable systems, composed of a center conductor, insulating dielectric, conductive shield and optional protective covering. conductivity The ability of a material to allow electrons to flow, measured by the current per unit of voltage applied. It is the reciprocal of resistivity.ANSI SCTE 244-2018 pdf download
