Fiber Distribution Box

SJ-FTTH-SK18-A 16 Cores FTTH Fiber Optic Terminal Box

The SJ-FTTH-SK18-A is a 16-core plastic fiber terminal box used as the termination point between feeder and drop cables in FTTH networks. It holds 16 fusion or mechanical splices and 16 SC adapters in a flip-up cassette, and is supplied with one 1×16 PLC splitter as standard. The PC+ABS enclosure measures 275 × 175 × 80 mm, weighs 1.22 kg, seals mechanically to IP65, and supports wall or pole mounting. It accepts 2 × 3 mm indoor drop cables and outdoor figure-8 self-supporting cables for flexible last-mile deployment.

Key Features

  • 16 splices and 16 SC adapters in one enclosure — one compact termination point can serve up to 16 subscriber drops.
  • 1×16 PLC splitter included — fitted as standard, ready for GPON or XGS-PON distribution to 16 subscribers.
  • IP65 mechanical sealing — the enclosure is dust-tight and protected against water jets for indoor or sheltered outdoor service.
  • Indoor and aerial drop-cable compatibility — accepts 2 × 3 mm indoor FTTH drop cable and outdoor figure-8 self-supporting cable.
  • Flip-up splice cassette — keeps fibers accessible for re-entry and maintenance without disturbing adjacent circuits.
  • Controlled bend radius of at least 40 mm — supports orderly routing of bend-sensitive drop fibers.
  • Corrosion-resistant internal hardware — stainless steel plate and anti-rust fasteners support long-term field use.

Why Pre-Terminated Drops Matter

Pairing this box with pre-terminated fiber cable assemblies can remove field termination from the subscriber side. The prepared assembly connects directly to the matching adapter, reducing installation time, labor per subscriber, and connector-quality variation in the field. For projects that prefer splicing, the internal cassette supports both fusion and mechanical splices.

Where the SJ-FTTH-SK18-A Fits

In an FTTH ODN, the SJ-FTTH-SK18-A sits at the final distribution point before subscriber drops. A feeder or distribution cable enters the enclosure, fibers are spliced and routed through the integrated 1×16 splitter and SC adapters, and as many as 16 drop cables leave through sealed entries. Typical placements include multi-dwelling-unit walls, poles serving residential clusters, and street-level access points.

For sites exposed to standing water or handhole flooding, consider the MBN-FOSC-A14-A 16-port IP68 fiber termination box.

Installation Notes

  • Wall or pole mounting: Keep cable entries facing downward and form drip loops before the enclosure.
  • Cable entry: Use the 16 sealed drop entries (Φ3–8 mm) and secure every cable before routing fibers into the cassette.
  • Fiber routing: Follow the internal guides and maintain a bend radius of at least 40 mm.
  • Closing: Seat the gasket evenly and fully compress the mechanical seal before returning the box to service.

FAQ

FAQ: SJ-FTTH-SK18-A

What is the SJ-FTTH-SK18-A used for?

It is installed between feeder or distribution fiber and subscriber drop cables in an FTTH network. Fibers are spliced, routed, and connected inside one protected distribution enclosure.

Does the SJ-FTTH-SK18-A include a PLC splitter?

Yes. One 1×16 PLC splitter is fitted as standard, so the box is ready to serve 16 subscribers on a GPON or XGS-PON split plan.

Which adapter type does it accept?

The standard configuration is 16 SC adapters. Contact us if your project requires a different adapter layout.

What is the enclosure protection rating?

It uses IP65 mechanical sealing, making it dust-tight and resistant to water jets. For locations exposed to standing water or flooding, select an IP68-rated enclosure.

Which drop cables can be used?

The enclosure accommodates 2 × 3 mm indoor FTTH drop cable and outdoor figure-8 self-supporting drop cable through 16 sealed entries (Φ3–8 mm).

Can it be mounted on a pole?

Yes. Both wall and pole mounting are supported.

What is the splice capacity?

The flip-up cassette holds 16 fibers and supports fusion or mechanical splicing while maintaining a controlled bend radius of at least 40 mm.

What are the dimensions and weight?

The enclosure measures 275 × 175 × 80 mm and weighs 1.22 kg.

Is it suitable for indoor use?

Yes. Its compact PC+ABS housing is suitable for indoor MDU distribution points as well as wall- or pole-mounted outdoor applications within its IP65 rating.

Can I request a sample or datasheet before a bulk order?

Yes. Send the required adapter type, splitter plan, mounting method, cable type, and quantity. The BWNFiber team will confirm the configuration and reply with documentation, pricing, and delivery support.
