The BWN-PLC-IM-2X4-SC-UPC is a 2×4 PLC splitter with SC/UPC ports in an ABS box module. Two input fibers are each split evenly across 4 outputs over the full 1260-1650nm band, with 7.6dB max insertion loss and -40~+85°C operation for PON, FTTH and enterprise distribution.

The BWN-PLC-IM-2X4-SC-UPC is a 2×4 PLC (planar lightwave circuit) optical splitter in an ABS box module, factory-terminated with SC/UPC connectors. It accepts up to two input fibers and distributes each input signal evenly across 4 output ports over the full 1260-1650nm window, so one or two feeder legs can serve 4 drop lines in PON, FTTH and enterprise networks.
Order this configuration when you need 4 drops per distribution point plus a second input for a protection feed or a second service, and when the installed plant is UPC-polished. The 100×80×10mm ABS module sits inside distribution boxes, splice trays and closures; it is not a sealed outdoor enclosure on its own. If your build specifies SC/APC with longer jacketed leads, see the 2×4 cable-type sibling linked below. For category context, see the insertion ABS box module range and the PLC splitter category.

This unit ships with SC/UPC connectors (blue housings). Mate it only with UPC-polished jumpers: plugging a UPC connector into an APC (green, 8° angled) adapter leaves an air gap, risks end-face damage, and collapses return loss at that joint. Family options: SC, LC or ST interfaces, APC or UPC polish; G657A bend-insensitive singlemode or customer-specified fiber at 0.9/2.0/3.0mm diameter, 1m standard leads.
The module plugs onto standard SC adapter plates inside distribution boxes, closures and cabinet builds — pair it with our fiber distribution boxes and fiber access terminals for a complete distribution point.
For boxes, closures and drop hardware around this splitter, see our FTTx supporting products.
2×4 or 1×4? Choose 2×4 when a second feeder must reach the same 4 outputs — feeder protection or a second service source. Choose 1×4 for single-feed builds with one less input to manage.
UPC or APC? Match the polish already in the field. SC/UPC (blue) fits enterprise, legacy CATV and data-network plant. Many operator PON standards specify SC/APC (green) — if that is your specification, see the 2×4 cable-type SC/APC sibling below.
Which package? This ABS box suits distribution boxes, wall enclosures and ODFs — see the insertion ABS box module range. Pick a steel-tube mini module for splice closures, a cable-type cassette for longer lead routing, or a rack panel for ODF frames.
Budget check. Start from the 7.6dB splitter loss, add connector pairs and splice points along each drop, and confirm the total against your OLT/ONU budget with the splitter loss chart (1×2 to 1×64).

Optical performance is verified against the parameters in the specification table above — insertion loss, uniformity, return loss, PDL, directivity and wavelength dependent loss. Compliance with Telcordia GR-1209-CORE and GR-1221-CORE is stated per BWNFiber product documentation.
Standard build: 2×4 split, SC/UPC, G657A fiber, 1m leads, 100×80×10mm ABS box; fiber diameter, lead length and connector mix customizable per order.

A PLC (planar lightwave circuit) splitter packaged in a protective ABS box module with connectorized input and output leads. The enclosed module mounts directly inside distribution boxes, cabinets and closures — unlike a bare steel-tube splitter, it does not need a sealed host enclosure to protect the chip.
A 1×4 takes one input to four outputs. A 2×4 has two inputs feeding the same 4-way split plane — used for main and backup feeder redundancy, or for carrying two services into one distribution point. It is not two independent 1×4 splitters in one box.
The 2×4 specification for this series is 7.6dB maximum insertion loss with 1.0dB uniformity. Add connector and splice losses when you build the link budget, and verify the total against your OLT/ONU power budget.
Match the plant. Choose UPC when the surrounding infrastructure is UPC-standardized (enterprise, legacy CATV, data networks). Choose APC when the link carries PON-based FTTH services where reflectance must stay low — see the 2×4 cable-type SC/APC sibling linked above.
Yes. PLC splitters are bidirectional passive devices — the same module can split one signal downstream or combine signals upstream. Loss values apply per pass in either direction.
Yes, when installed inside a sealed cabinet, closure or distribution box. The module is rated -40~+85°C; the host enclosure provides the weather sealing.
Yes — send your split configuration, connector polish, lead type/length and quantities to our sales team for a configuration review, documentation and pricing.
