Key Features
- Protects the weakest point of the drop — the fusion splice or field connector between drop cable and pigtail is enclosed, sealed and strain-relieved instead of exposed.
- Fits real field configurations — holds 1 SC simplex adapter plus 2 fast connectors, or a single fusion splice with a protection sleeve.
- Silicone ring sealing — the cover closes on a silicone rubber ring that keeps dust and moisture away from the connection point.
- Standard 2 × 3 mm drop cable entry — both ends lead cable in and out; also accepts 3 mm round cable.
- Two mounting options — screw fixing with 150 mm hole spacing, or double-sided adhesive tape for furniture, cabinets and rented premises.
- Compact and light — 160 × 47.9 × 16 mm, mounts along baseboards, on walls or inside weak-current boxes.
Where the SJ-FTTH-SK-2W Fits
- FTTH drop repair and extension — enclose the splice point when a drop cable is repaired, extended or re-routed.
- Subscriber entry points — protect the transition from outdoor drop cable to indoor cabling at the wall.
- Fast-connector terminations — house field fast connectors where no fusion splicer is available.
- Corridors and weak-current boxes — tidy protection for exposed single-fiber connections in MDU risers.
This is the standard version of the SK-2 protection box family. For humid indoor locations, see the sealed SK-2B version below; for aerial or multi-core runs, see the 6-core SK-6C.
Installation Notes
- Strip and splice the drop cable (or terminate with fast connectors), then lay the connection into the base channel before closing the cover.
- Keep fiber bends above the minimum bend radius inside the box; do not force the cover onto a stressed coil.
- For screw mounting, mark the 150 mm hole spacing; for adhesive mounting, clean and dry the surface first.
- Seat the silicone ring evenly before closing — a pinched ring is the most common cause of a dusty or damp interior.
