Fiber Wall Socket

SJ-FTTH-SK-6C 6 Core Fiber Optic Splice Protection Box

The SJ-FTTH-SK-6C is a 6-core fiber splice protection box for through-runs: one cable enters and one leaves through the two Ø8 mm ports, while inside, up to six fusion splices are held and protected. A silicone sealing gasket between cover and base keeps the splices dust- and moisture-protected, and the 190 × 90.1 × 21.5 mm ABS body mounts on walls or hangs on aerial strands — making it the multi-core member of the protection box family for risers, corridors and aerial drop routes.

Key Features

  • 6 splices in one box — up to six fusion splices protected in a single through-run enclosure.
  • 1-in-1-out cable layout — one Ø8 mm cable enters, one leaves: a protected splice point on a through cable route.
  • Silicone gasket sealing — the cover closes on a silicone sealing gasket that keeps dust and moisture away from the splices.
  • Wall or aerial mounting — fix to a wall or hang on an aerial strand along drop routes.
  • Ø8 mm cable ports — accept standard round drop and distribution cables.
  • Rated −40 °C to +70 °C — covers risers, corridors and sheltered aerial positions.

Where the SJ-FTTH-SK-6C Fits

  • Through-run splice points — protect up to six splices where a {DROP} or distribution cable is joined mid-route.
  • Risers and corridors — multi-core splice protection between building sections.
  • Aerial drop routes — hang the box on the strand at aerial splice points.

Need single-core or adapter-style protection? See the SK-2W (standard), SK-2B (sealed) or SK-2Y (wall-mount 1-port). For larger outdoor demarcation, see our fiber termination box. Full range: Fiber Wall Socket category.

Installation Notes

  • For wall mounting, fix the base with screws; for aerial use, hang the box on the strand before splicing.
  • Splice the fibers with protection sleeves and seat them in the slots; keep bends above the minimum radius.
  • Check the silicone gasket sits evenly before closing the cover — a pinched gasket breaks the seal.

FAQ

SJ-FTTH-SK-6C 6 Core Fiber Optic Splice Protection Box FAQ

What is a 6 core fiber protection box used for?

It encloses and protects up to six fusion splices on a through cable run — one cable in, one cable out — in risers, corridors and aerial drop routes.

Can the SK-6C be used outdoors or aerial?

The box supports wall mounting and aerial hanging, and the cover seals with a silicone gasket. For fully exposed outdoor or buried applications, use an IP-rated closure instead.

What cable sizes does it accept?

Two cable ports (1 in, 1 out) accept cable up to Ø8.0 mm.

How many splices fit inside?

Up to six fusion splices with protection sleeves.

What is the difference between the SK-6C and SK-2W?

The SK-6C protects six splices on a through-run with Ø8 mm ports; the SK-2W is a single-core adapter-style box holding an SC adapter and fast connectors.

Does it include splice sleeves?
