ANSI/TIA-568.4-E
Updated 2026-10-25
Data records
- ANSI/TIA-568.4-E (2022) treats horizontal cabling as Cabling Subsystem 1, the run from the equipment outlet to the serving distributor, and backbone cabling as the subsystems that join distributors to one another.
- ANSI/TIA-568.4-E (2022) defines dual, tri and quad shield coaxial cable by the number and order of the foil and braid layers that make up the outer conductor.
- Clause 8.1 of ANSI/TIA-568.4-E (2022) makes acceptance testing of coaxial cabling mandatory, in three parts: a visual inspection and a verification, each covering the whole installation, followed by a choice between qualification and performance characterization.
- ANSI/TIA-568.4-E (2022) names typical installation damage that acceptance testing is meant to catch, including fasteners driven through the cable, kinks at drilled framing, tears from pulling, and poorly installed connectors.
- For field measurements, clause 6.3 of ANSI/TIA-568.4-E (2022) replaces any calculated insertion loss limit that falls below a fixed floor value with that floor.
- ANSI/TIA-568.4-E (2022) recommends, without requiring, performance characterization at trim-out, which measures the installed link against the clause 6 electrical criteria, in practice insertion loss and return loss.
- Under clause 8.4 of ANSI/TIA-568.4-E (2022), qualification is done at trim-out, either with live signals and the application's own equipment or with a qualification test instrument such as a signal level meter.
- Clause 8.3 of ANSI/TIA-568.4-E (2022) describes verification as a check for opens, shorts and correct end-to-end connectivity, performed during rough-in, ahead of insulation and wall sheathing.
- Clause 8.2 of ANSI/TIA-568.4-E (2022) calls for visual inspection of each run after installation but before insulation and wall sheathing, looking for cable damage, inadequate separation from interference sources, improper bends, excess length, faulty connectors and improper bonding at the demarcation point.
- Informative Annex A of ANSI/TIA-568.4-E (2022) explains how the cable insertion loss functions were fitted to discrete SCTE and SBCA values and compares the cable, connector and cabling requirements with those of ISO/IEC 11801-1.
- ANSI/TIA-568.4-E (2022) ends with three informative annexes: background on how the coaxial requirements were derived, a description of the multipoint bus arrangement, and a bibliography.
- The transmission requirements in clause 6 and clause 7.1 of ANSI/TIA-568.4-E (2022) are limited to Series 6 and Series 11 cable of non-plenum construction; plenum cable and the other recognized cable types follow their manufacturers' specifications.
- Clause 4.2 of ANSI/TIA-568.4-E (2022) requires the far end of a bus backbone to be closed with an impedance-matching termination unless the last device on the bus already provides the match.
- Clauses 7.1.4 and 7.1.5 of ANSI/TIA-568.4-E (2022) set cable screening attenuation and transfer impedance requirements by shield construction, measured with the triaxial methods of IEC 62153-4-4 and IEC 62153-4-3.
- Clause 7.1.1 of ANSI/TIA-568.4-E (2022) requires each recognized cable type to meet a named SCTE cable specification, and allows Series 6 cable for satellite service to meet the SBCA Series 6 recommended practices instead.
- Clauses 7.1.2 and 7.1.3 of ANSI/TIA-568.4-E (2022) set the insertion loss per unit length of Series 6 and Series 11 cable as a frequency function and a minimum cable return loss.
- Clause 7.3.1.1 of ANSI/TIA-568.4-E (2022) ties the male F connector for each cable series and the indoor and outdoor female F feed-through to specific SCTE connector specifications, and recommends compression-type male F connectors.
- ANSI/TIA-568.4-E (2022) uses the word shall for mandatory requirements, while should, may and desirable mark advisory text and are treated as interchangeable.
- Clause 7.2 of ANSI/TIA-568.4-E (2022) covers equipment and patch cords: miniature and flexible cords must meet the Series 6 transmission requirements except insertion loss, which has its own limit tied to Series 6 cable, all cords end in male F connectors, and factory-terminated cords are recommended.
- Clause 6.3 of ANSI/TIA-568.4-E (2022) sets a maximum cabling insertion loss as a function of frequency for each cable series and subsystem, built from a cable term at the maximum length plus two connection terms and stated at a reference temperature, with an extended frequency range for satellite cabling.
- An informative table in clause 6.3 of ANSI/TIA-568.4-E (2022) evaluates the cabling insertion loss limit at a list of frequencies for each series and subsystem, for information only; the governing requirement remains the frequency function.
- ANSI/TIA-568.4-E (2022) points to ANSI/SCTE 47 as the attenuation test method, as a recommendation for installed cabling and as a requirement for cable.
- Clause 5.2 of ANSI/TIA-568.4-E (2022) gives an advisory, not mandatory, maximum link length for each of the two drop-cable series and recommends trunk, feeder, distribution or braided multipurpose cable for longer links.
- Clause 7.3.1.2 of ANSI/TIA-568.4-E (2022) requires mated F connectors to meet the ISO/IEC 11801-1 broadband coaxial connector type for cable television, except for insertion loss, which it sets separately as a frequency function with a floor.
- Clause 2 of ANSI/TIA-568.4-E (2022) cites its normative references without dates, so the latest edition of each applies; most are SCTE cable and connector specifications, joined by IEC test methods, ISO/IEC 11801-1 and ANSI/TIA-568.0.
- ANSI/TIA-568.4-E (2022) requires a threaded SCTE plug on trunk, feeder and distribution cable and permits BNC connectors for quick connection when they meet the impedance-matched annex of IEC 61169-8.
- Clauses 7.4 through 7.10 of ANSI/TIA-568.4-E (2022) point splitters, traps and filters, inline splices, ground blocks, attenuators, amplifiers and termination devices to their SCTE specifications, making the splice, ground block and termination references mandatory. Not settled.
- Clause 5.1 of ANSI/TIA-568.4-E (2022) recognizes four coaxial cable families for structured cabling: Series 6, Series 11, trunk, feeder and distribution cable, and braided multipurpose cable.
- Clause 6.4 of ANSI/TIA-568.4-E (2022) sets a minimum return loss for installed cabling across the cable television band and a separate, lower minimum across the satellite extension, with IEC 61196-1-112 recommended as the test method.
- Clause 6.5 of ANSI/TIA-568.4-E (2022) states screening attenuation requirements for cabling by shield construction but does not require them to be field tested; they are expected to follow from compliant components and installation practice.
- Clause 5.3 of ANSI/TIA-568.4-E (2022) requires Series 6 and Series 11 cable to end in male F connectors at cross-connects and, at the outlet, a male F connector mated to a female F feed-through, with sealed connectors outdoors and a separate threaded male connector on trunk, feeder and distribution cable.
- Clause 6.2 of ANSI/TIA-568.4-E (2022) defines the test link as the installed cable together with the mated connections at both of its ends, drawn separately for horizontal and backbone links.
- Clause 4 of ANSI/TIA-568.4-E (2022) adopts the generic cabling topology of ANSI/TIA-568.0 but excludes consolidation points and horizontal connection points from coaxial cabling.
- ANSI/TIA-568.4-E (2022) recognizes two coaxial topologies: a star, and a bus backbone that feeds star-wired horizontal cabling, sometimes called tree and branch.
- Annex A of ANSI/TIA-568.4-E (2022) explains that the cable transfer impedance limit exists to restrict radio-frequency emissions in the lower part of the band.
