1 Scope
This part of IEC 60728
lays down the measuring methods, performance requirements and data publication requirements
of optical equipment of cable networks for television signals, sound signals and interactive
services loaded with digital channels only.
This document
-
• applies to all optical transmitters, receivers, amplifiers, directional couplers, isolators, multiplexing devices, connectors and splices used in cable networks;
-
• covers the frequency range 5 MHz to 3 300 MHz;
NOTE The upper limit of 3 300 MHz is an example, but not a strict value.
-
• identifies guaranteed performance requirements for certain parameters;
-
• lays down data publication requirements with guaranteed performance;
-
• describes methods of measurement for compliance testing.
All requirements and published data relate to minimum performance levels within the
specified frequency range and in well-matched conditions as might be applicable to
cable networks for television signals, sound signals and interactive services.
