1×32 Cassette PLC Splitter Overview
The BWN-PLC-CT-1X32-SC-APC-2.0 is a 1×32 planar lightwave circuit (PLC) splitter in a protected ABS cassette module: one PON input in, thirty-two SC/APC outputs out, on 2.0mm pigtails. It is built for the distribution point of an FTTH network — the cassette drops into a fiber distribution box, street cabinet or optical panel, where the enclosure provides the environmental protection and the splitter provides a single-stage 1:32 split for a full GPON branch.
A planar chip keeps insertion loss flat across the 1260–1650nm band, so the same module carries GPON (1310/1490nm) today and XGS-PON (1270/1577nm) when the network upgrades. For this 1×32 model, the published insertion loss is 16.5/16.9dB (P/S grade) with 1.5dB-class uniformity across all 32 ports. For the full family, see the cassette PLC splitter category.
Key Features
- Single-stage 1:32 split: one feeder fiber serves 32 drops — the standard GPON branch ratio — without a cascaded second splitter stage.
- SC/APC connectors throughout: the PON-standard 8° angled polish keeps reflectance low (≥55dB return loss) on GPON/XGS-PON links.
- Protected cassette format: the ABS module encloses the chip and pigtail routing, ready for distribution boxes, cabinets and splitter panels.
- Planar wavelength flatness: uniform loss across ports and across 1260–1650nm — unlike ratio-dependent FBT couplers.
- Wide temperature rating: -40°C to +85°C operating and storage, for unheated street cabinets and closures.
- Configurable at order: pigtail length (1m standard) and fiber type (G657A standard) confirmed on the datasheet before production.

Connectors, Fiber Types & Compatibility
This model ships with SC/APC connectors on the input and all 32 outputs — the default polish for PON outside plant, where the 8° angled end-face keeps reflectance low on GPON and XGS-PON links. Fiber is G657A bend-insensitive singlemode as standard; G.652.D or customer-specified fiber is available on request.
The 2.0mm jacketed pigtails (1m standard; 0.9mm and 3.0mm constructions available) mate with SC adapter plates in fiber distribution boxes, street cabinets, splitter panels and ODF frames. The cassette itself is a protected component, not a sealed outdoor device — it always installs inside a protective enclosure.
Applications
- FTTH / GPON distribution: one OLT PON port serves 32 subscribers from a single cassette at the distribution point.
- MDU and campus ODN: the central split for building risers and campus fiber distribution.
- Cabinet-based splits: street cabinets and cross-connect points where a protected module simplifies patching and troubleshooting.
- PON upgrade paths: the 1260–1650nm window covers GPON, XGS-PON and NG-PON2 wavelengths, so the passive layer survives an active-equipment upgrade.
How to Choose the Right Configuration
1. Split ratio: 1×32 covers a full GPON branch in one stage. Choose 1×16 or 1×8 for smaller branches, or a cascaded two-stage design when the topology or budget requires it.
2. Connector polish: APC for PON links (low reflectance is mandatory on GPON/XGS-PON); UPC variants exist for non-PON enterprise builds — see the 1×32 SC/UPC 3.0mm sibling.
3. Connector form: this page is the SC version; if panel density is the constraint, see the LC/APC 1×32 sibling.
4. Package: this cassette module for distribution points with adapter fields; a steel-tube or bare format when the splitter is spliced inside another sealed closure; an LGX card or the 1×32 insertion-module box for rack and cabinet ecosystems.
5. Pigtails: match jacket diameter (0.9/2.0/3.0mm) and length to the enclosure’s routing space.
