CAT7 S/FTP Shielded Cable 1000ft - LSZH, 23AWG Solid Copper 10G

This is Cat7, the most heavily shielded cable in the line. Each of the four pairs is wrapped in its own foil, and a tinned copper braid surrounds all four. The foil keeps the pairs from interfering with each other and blocks high-frequency noise; the braid blocks the low-frequency fields from motors and power distribution and gives the shield a solid path to ground. It's rated to 1000 MHz, twice Cat6A. The jacket is low-smoke zero-halogen, so it gives off little smoke and no corrosive gas in a fire, and it's UV-rated, so a run can pass through an outdoor enclosure without switching to a separate outdoor cable.

The 23 AWG solid copper conductors have HDPE insulation. It comes on a 1000 ft wooden spool with footage markings on the jacket.

Features

• 10GBase-T over a full 100 m channel, with the margin to spare. It also runs 5G, 2.5G, and 1G links, and works with Cat6A, Cat6, and Cat5e equipment.
• 1000 MHz, ISO/IEC 11801 Class F. Twice the bandwidth of Cat6A, for the cleanest 10G channel copper can deliver and headroom for what comes after.
• S/FTP double shielding. Foil on every pair plus an overall tinned copper braid, for the most interference rejection and the lowest crosstalk available in a data cable.
• Drain wire. It gives the shield layers a path to ground at the patch panel.
• LSZH jacket, IEC 60332-1. Low smoke and no halogen acids in a fire, for enclosed spaces and specifications that require it.
• UV-rated, indoor and outdoor. One cable can run inside, through an exterior enclosure, and back inside without a splice, across a -20 °C to 60 °C operating range.
• 23 AWG solid bare copper. Full-gauge solid conductors for the lowest loss over a full channel and the least voltage drop on PoE runs. No copper-clad aluminum.
• HDPE insulation. Tight, consistent pair twists for crosstalk control.
• Sequential footage markings. You can see what's left on the spool and cut runs to length without a tape.
• 1000 ft wooden spool. Standard TIA-568 pair colors inside.

Where It Fits

It suits tunnels, rail and transit facilities, marine and offshore installations, broadcast plants and recording studios, hospitals and imaging centers, industrial control rooms, data centers and buildings with an LSZH cabling specification, international and export projects built to IEC rules, and outdoor conduit runs between buildings or to remote cabinets where both the noise floor and the smoke rating are the reasons for the spec.

Good to Know

Two things to know before you buy. First, Cat7 is an ISO standard written around its own connectors (GG45 and TERA); terminated on standard RJ45 hardware, which is how nearly everyone installs it, the channel certifies as Cat6A, 10G over 100 m, with the S/FTP shielding as the reason to choose it. Buy it for the shielding and the margin, not for speeds beyond 10G on RJ45. Second, LSZH is an international classification, not a North American one. This cable carries the IEC 60332-1 flame rating, not a CM, CMR, or CMP listing, so under the NEC it can't be run in walls, risers, or plenums in a U.S. building the way listed cable can; it's for enclosed, exposed, and conduit installations where LSZH is specified, and for projects built to IEC rules. For a riser or in-wall run in an ordinary U.S. building, use the CMR Cat7. A shield only works when it's grounded: terminate on shielded jacks and patch panels that bond to the braid, ground it at one end, and use shielded patch cords and switch ports so the shield is continuous end to end. Terminating S/FTP takes longer than F/UTP, so allow for it in the labor estimate. This cable isn't rated for direct burial. LSZH jackets are stiff and scuff more easily on a pull, so use a lubricant and respect the bend radius, about four times the cable diameter. Solid conductors are for permanent runs; terminate on jacks and patch panels, not crimped plugs.
