MBN-FOSC-A11 8 Ports FTTH Fiber Optic Splitter Box

The MBN-FOSC-A11 is an IP65-rated 8-port fiber optic splitter box for FTTH distribution points, where feeder cables are spliced, split, and routed to subscriber drop cables. It is supplied with one 1×8 PLC splitter as standard and provides 72-core splice capacity inside a 315 × 200 × 120 mm PC+ABS enclosure. Eight SC/APC adapter ports serve drop connections, while four feeder entries and eight drop ports accept cables from Φ7.0 to Φ16.0 mm, sealed mechanically with a rubber ring and clip lock. The box supports wall, pole, or aerial mounting and typically serves as the last distribution point before subscriber drops in GPON and XGS-PON access networks.

Key Features

  • Splitter included and ready to deploy: One 1×8 PLC splitter is supplied as standard for GPON or XGS-PON signal distribution.
  • Eight SC/APC adapter ports: APC interfaces help control back-reflection in PON access networks.
  • 72-core splice capacity: Separate splicing and distribution areas organize feeder fibers, splitter pigtails and drop connections.
  • IP65 mechanical sealing: A rubber ring and clip-lock design protects against dust and water jets for appropriate indoor and outdoor edge installations.
  • Flexible cable entries: Four feeder inputs and eight drop outputs accept cables from Φ7.0 to Φ16.0 mm.

Where the MBN-FOSC-A11 Fits in an FTTH ODN

In a typical PON access network, the feeder cable from the OLT side is spliced inside the box, divided by the integrated PLC splitter, and routed to as many as eight subscriber drop cables through the SC/APC ports. This makes the MBN-FOSC-A11 the final distribution point before the last-mile drop.

The enclosure can be installed on a pole outside a residential cluster, on the wall of a multi-dwelling unit, or on an aerial strand along the drop route. Pre-terminated SC/APC drops connect directly at the adapter side, while conventional network builds can manage feeder and drop splicing inside the box.

Installation: Wall, Pole and Aerial Mounting

  • Wall mounting: Fix the box through its rear mounting points and keep cable entries facing downward to reduce water tracking along the cables.
  • Pole mounting: Use compatible project-specified banding hardware and position the enclosure so technicians can open the cover fully during splicing. Confirm the mounting hardware supply scope with the quotation.
  • Aerial mounting: Secure the box to the strand and route feeder and drop cables with appropriate drip loops and strain relief.
  • Before closing: Check that the rubber ring sits evenly in its groove, engage the clip locks uniformly and install sealing plugs in unused cable ports. Maintain the specified cable bend radius at every entry.

FAQ

FAQ: MBN-FOSC-A11

What is the MBN-FOSC-A11 used for in an FTTH network?

It is installed at the distribution point between feeder and drop cables. Feeder fibers are spliced inside the box, divided by the integrated 1×8 PLC splitter and routed through eight SC/APC ports to subscriber drops.

Is the 1×8 PLC splitter included with the box?

Yes. One 1×8 PLC splitter is supplied as standard for GPON or XGS-PON distribution.

What is the ingress protection rating?

The enclosure is rated IP65, meaning it is dust-tight and protected against water jets. IP65 is not a submersion rating. For flood-prone pits or environments requiring IP68 protection, review the MBN-FOSC-A17-8 IP68 closure.

Does it use SC/APC or SC/UPC connectors?

The standard configuration uses eight SC/APC adapters. Contact BWNFiber if the project requires a different adapter interface.

What cable diameters does it accept?

The four feeder inputs and eight drop outputs accept cables from Φ7.0 to Φ16.0 mm.

Can it be pole-mounted, and is the mounting hardware included?

The enclosure supports pole mounting as well as wall and aerial installation. Confirm the required bracket or banding hardware and its supply scope in the quotation.

What is the maximum splice capacity?

The maximum splice capacity is 72 cores, with separate splicing and distribution areas for organized fiber management.

What insertion loss should I use for the 1×8 splitter?

Insertion loss depends on the specified splitter grade, wavelength and project configuration. Use the unit-level test report for final link-budget calculations and review the 1×8 PLC splitter specifications and power budget guide.

How is the MBN-FOSC-A11 different from the MBN-FOSC-A14?

The A11 combines a standard 1×8 PLC splitter and 72-core splicing in one SC/APC distribution box. The A14 is a pre-connectorized closure with waterproof SC interfaces for plug-and-play drop connections.

Can I request a sample, datasheet or test report before a bulk order?

Yes. Submit the required splitter ratio, adapter interface, mounting method and quantity. The sales team can provide the available datasheet, sample information and applicable unit-level test documentation.
