Overview: 2×32 PLC Splitter in a Steel Tube with LC/APC
The BWN-PLC-MMST-2X32-LC-APC is a planar lightwave circuit (PLC) splitter that distributes two optical inputs evenly across 32 outputs inside a compact steel tube, factory-terminated with LC/APC connectors. It serves PON and FTTx distribution points that need dual-input architecture and high connector density in a splice-in package.
This configuration fits ISPs, FTTH contractors, and passive optical LAN builders who run out of tray space before link budget. One tube carries 34 LC connections — two inputs plus 32 outputs — and drops into a splice closure or distribution box; LC’s 1.25mm ferrule lets a tray position hold roughly twice as many terminations as SC’s 2.5mm ferrule. With 17.5dB maximum insertion loss and 1.8dB uniformity, it supports redundant-OLT feeding and GPON/XGS-PON coexistence. For concept background, see our fiber optic splitter overview and the PLC splitter category.
Key Features
- 2 inputs × 32 outputs in one steel tube: 34 LC/APC ports in a splice-in package — the densest connectorized steel-tube splitter in the BWNFiber range.
- 17.5dB max insertion loss, 1.8dB uniformity: every one of the 32 outputs lands inside a predictable budget window.
- LC/APC small-form-factor connectors: 1.25mm ferrule versus 2.5mm on SC, so closures and boxes terminate about double the ports per position.
- 55dB return loss, 55dB directivity: APC-grade reflection control for PON links that also carry RF video wavelengths.
- 1260-1650nm full band, 0.5dB wavelength dependent loss: transparent to 1310/1490/1550/1577nm services sharing one ODN.
- -40~+85°C operating and storage, 0.5dB temperature stability: rated for sealed closures and outdoor cabinets.
- G657A bend-insensitive pigtails: 0.9mm, 2.0mm, or 3.0mm diameter, 1m standard or customized.

Connectors, Fiber Types & Compatibility
The standard build is LC/APC on G657A bend-insensitive fiber. APC’s angled endface keeps return loss at 55dB, which matters when PON wavelengths share plant with RF video. SC, LC, and ST connectors in APC or UPC polish are available options per the configuration list — never mate APC pigtails into UPC adapters. Use 0.9mm pigtails inside splice trays; 2.0mm and 3.0mm jacketed leads suit runs leaving the enclosure. The tube splices directly into fiber optic splice closures, distribution boxes, and ODF adapter fields.
Applications
- GPON + XGS-PON coexistence: both OLT services enter the two inputs and reach all 32 outputs, so a GPON ODN can overlay XGS-PON without re-splicing.
- Redundant OLT feeding: with main and standby OLT ports on the two inputs, all 32 subscribers stay lit through a port or line-card failure.
- Dense FTTH distribution closures: 34 LC terminations where the same tray position would hold roughly half as many SC connectors.
- CATV/RF video overlay on PON: 55dB return loss at APC polish protects reflection-sensitive video wavelengths.
- Passive optical LAN risers: the tube mounts inside wall boxes and riser enclosures where cassette or LGX frames do not fit. See related FTTx supporting products for the enclosure side.
How to Choose: Split Count, Connector, Package, Pigtail
- 1×32 or 2×32: a single OLT feed only needs a 1×32 splitter. Choose 2×32 when you plan redundant feeding or a two-service overlay — both inputs distribute to every output.
- LC or SC: choose LC (this page) when tray and panel positions are the constraint; choose SC when field crews standardize on SC handling.
- Steel tube or housed: tube for splice closures and small boxes; cassette for FDH adapter plates; LGX or rack for ODF frames. The blockless mini PLC splitter category covers smaller split counts in the same tube format.
- Polish: APC for PON with RF video overlay; UPC where the reflection budget is relaxed.
- Pigtail: 0.9mm for tray routing, 2.0/3.0mm where leads exit the box; 1m standard, custom lengths on request.
Sibling Configurations vs This 2×32 LC/APC Steel Tube
This page keeps one combination: 2×32, LC/APC, steel tube. Adjacent needs belong to sibling pages:
| If you need | Choose |
|---|---|
| Steel tube with fewer ports (2×8) and SC/APC | 2×8 steel tube PLC splitter SC/APC |
| 2×32 mounted on FDH adapter plates, SC/APC | cassette PLC splitter range |
| 1×32 or 1×64 in a 19-inch ODF frame | rack-mounted PLC splitter range |
| LC density in an LGX box (2×8 LC/UPC) | LGX box LC/UPC 2×8 PLC splitter |
None of the siblings pack 34 LC ports into a splice-in tube — that is the gap this model fills.
