IS 14231 : Part 4 : 1995 Cabled Distribution Systems for Television and Sound Signals - Specification - Part 4 : Passive Coaxial Wideband Distribution Components

1 Scope

1.1 This standard applies to receiver leads, system outlets,splitters aud subscriber's taps, passive one and two port devicescomprising filters, attenuators, equalizers, galvanic isolators,power injectors, cable splices, terminating resistors and deliverypoints in the frequency range 5 MHz to 1750 MHz.

Note 1 - There are two grades for taps and splitters and passiveone-and-two port devices. This enables the system designer tooptimize cost/performance, taking into account the size of thenetwork and local circumstances.

Note 2 - There is only one grade of system outlet and receiverlead. Different networks require the same performance and, whenintegrating networks, upgrading will be avoided.
