Key Features
- Flexible 2/4-port layout — two SC ports or four LC ports in the same slim housing; one SKU covers both single and multi-service points.
- Specified optical performance — IL < 0.2 dB and RL up to ≥ 60 dB (APC) keep the subscriber drop inside PON loss budgets.
- > 50 N cable retention — the strongest cable fixation in the range; pulls on the drop cable never reach the splice.
- Slim 25 mm profile — sits close to the wall in homes, corridors and offices.
- Standard drop cable entry — accepts 3.1 × 2.0 mm rubber FTTH drop cable.
- Rated −40 °C to +70 °C — covers unheated corridors and plant rooms as well as living spaces.
Where the SJ-FTTH-SK-1 Fits
- Flexible subscriber outlets — 2 × SC for standard drops, 4 × LC where more services share one point.
- Apartment and office entries — where the {DROP} terminates and room cabling begins.
- High-traffic positions — the > 50 N cable retention suits outlets in corridors and public areas.

Installation Notes

- Splice or field-terminate the fibers, seat the adapters, and coil surplus fiber with controlled bends.
- Keep adapter dust caps in place until the subscriber patch cords are connected.
