Key Features
- 4-port multi-fiber outlet — one socket for the live drop, spare fibers and second services, instead of multiple single plates.
- High-density LC option — up to eight LC ports in the same housing for office and FTTD layouts that need more fibers per point.
- Mid-size LM housing — 150 × 110 × 30 mm, large enough for organized patching behind the panel.
- SC or LC flexibility — port positions accept SC duplex or LC adapters to match the project standard.
- Dust-protected presentation — adapters sit behind the panel cover, shielded from dust and accidental pulls.
- Rated −40 °C to +70 °C — covers corridors, risers and plant rooms as well as living spaces.
Where the SJ-FTTH-LM-4 Fits
- Multi-fiber home and office outlets — one wall point serving several devices or services.
- FTTD work areas — desk clusters fed from a single 4-port socket.
- Apartment entry points — where the {DROP} terminates and room cabling begins.
Need more ports on one panel? See the 8-port LM-8. Need splice storage behind the outlet? See the SJ-FTTH-SK-8 4-port outlet box. Full range: Fiber Wall Socket category.
Installation Notes
- Fix the socket to the wall with screws; bring the incoming cable in and clamp it before terminating.
- Terminate fibers to pigtails or field connectors, then seat the adapters in the port positions.
- Route spare fibers with controlled bends — crowded housings are where bend-radius violations happen.
- For general wall-outlet mounting, see how to install a fiber wall socket in your house.
