ANSI SCTE 156-2019 pdf free download – Specification for Mainline Plug (Male) to Cable Interface.
The primary purpose of this specification is to assure acceptable electrical, mechanical and environmentalperformance of the cable and connector interface. The scope of this standard will be directed to
acceptable performance of impedance,galvanic action, loop resistance, cable retention, intermodulationdistortion, signal response, RF shielding, and watertight seals. This specification in no way should limit orrestrict any manufacturers from innovative designs and product improvements.
1. This specification applies to the interface between ANSISCTE 92, Specification for 5/8 – 24 Plug(Male),Trunk and Distribution Connectors and 75-ohm coaxial aluminum hardline cable
manufactured to ANSI/SCTE 15 and ANSI/SCTE100.
2. 75-ohm coaxial cables and connectors are used to transport radio frequency (RF) signals and ACpower between active and passive equipment.
3. Unless otherwise specified, all requirements in this document shall meet the performancerequirements stated herein after thermal conditioning from -40 C to 60 ℃.
4. This document includes requirements for DOCSIS 3.1 operation.
