ANSI OKs 3 SCTE Standards

Sept. 23, 2015
The American National Standards Institute has approved three SCTE standards. ANSI/SCTE 145 2015, "Test Method for Second ...

ANSI/SCTE 145 2015, "Test Method for Second Harmonic Distortion of Passives Using a Single Carrier," is intended to establish the standard methodology to measure second harmonic distortion in a cable system passive at high signal level conditions (50-60 dBmV). Due to the difficulty in acquiring multi-carrier signal generators with both 55 dBmV output and intermod beats at -120 dBc, the test procedure will use a single carrier source test method.

ANSI/SCTE 210 2015, "Performance Metrics for Energy Efficiency & Functional Density of Cable Data Generation, Storage, Routing, and Transport Equipment," covers powering metrics throughout the network, including hubs, headends, data centers, regional and national distribution data centers.

ANSI/SCTE 211 2015, "Energy Metrics for Cable Operator Access Networks," contains metrics for measuring the energy efficiency of access networks (ANs) that are utilized to transport information between a service provider and a plurality of users. For the purposes of this document, the AN includes all active and passive equipment between the headend or hub and the demarcation point at the user premises. The document does not include any equipment inside the hub, nor does it include any customer premises equipment (CPE).
