Key Features
- Standard 86-type format — matches the 86 × 86 mm plate format used worldwide in FTTH installations; sits flush on the wall for a clean finish.
- SC/APC port for PON networks — the angled polish of SC/APC keeps reflectance low on GPON/XGS-PON links, which is why operators standardize on it at the subscriber outlet.
- Termination and storage in one plate — the base fixes the incoming cable, protects the splice and stores surplus fiber; no separate box needed at the wall point.
- Flame-retardant housing — PC & ABS flame-retardant plastic for home and office environments.
- FTTD-ready — a user-end outlet for fiber-to-the-desktop in offices, hotel rooms and apartments.
- Family of four designs — the MN-4 series covers 1-port plates to 4-port sockets in the same 86 format, so projects can mix port counts with one look.
Where the SJ-FTTH-MN-4A Fits
- Residential FTTH — the wall point where the drop cable ends and the subscriber’s patch cord begins, in houses, villas and apartments.
- Fiber to the desk (FTTD) — office and workstation outlets fed by indoor cable.
- Multi-dwelling units (MDU) — one plate per dwelling unit, fed from the floor distribution point.
This plate is an indoor product. For outdoor or pre-connectorized distribution points, see our fiber termination boxes.
Need two ports instead of one? See the SJ-FTTH-MN-1-SC-APC 2-port fiber wall plate in the same 86 × 86 mm format.
Installation Notes
- Fix the plate to the wall with the supplied screws; keep the incoming drop cable above its minimum bend radius inside the base.
- Splice the drop cable to the pigtail or field-assembly connector inside the base, and coil surplus fiber without kinks.
- Keep the adapter dust cap in place until the subscriber patch cord is connected.
