1×17 80/20 Unbalanced PLC Splitter with SC/APC and 3 m Leads

BWNF-PLC-ABS-1×17-80-20-SCAPC-3M

This connectorized 1×17 PLC splitter uses one 80% path and sixteen 1.25% tap paths. The photographed assembly is identified as factory P/N PLC-B-1X17-3.0-3M-SC/APC and uses SC/APC connectors, G657A fiber, 3.0 mm pigtails and a 3 m reported length. It is not an equal 1×17 splitter, and it is not the same configuration as BWNFiber’s published 1×17 70/30 steel-tube model.

Primary action: Request the current datasheet, dimensional drawing and serial-matched optical report.
Submit: required quantity, exact ratio string, connector/polish, pigtail diameter and length, host-enclosure space, port-label plan, target loss budget and required compliance documents.
BWNFiber response, subject to internal approval: a configuration review and quotation package showing the proposed model, controlled specification, drawing, report availability, commercial terms and unresolved exceptions.

Short answer for buyers

Use this 1×17 unbalanced PLC splitter only when the approved network design calls for one higher-power 80% path plus sixteen lower-power 1.25% paths. Confirm the physical port labels, host-enclosure fit and worst-route optical budget before ordering. The readings below belong to photographed serial 2024095454; they are sample results, not universal production guarantees.

Key points

• 1 input and 17 outputs: one 80% path plus sixteen nominal 1.25% paths.
• SC/APC connectors are shown on the photographed assembly and named on its test report.
• The report lists G657A fiber, 3.0 mm pigtails, 3 m length and a 1260–1650 nm operating wavelength.
• The report lists a 120 × 80 × 18 mm package for the photographed unit. Request the current drawing before approving enclosure fit.
• Per-port insertion loss and PDL were recorded at 1310 nm and 1550 nm for serial 2024095454.
• Housing material: TBC — source required. Treat ABS as unverified until an approved drawing, BOM or controlled datasheet confirms it.
• GR-1209-CORE, GR-1221-CORE and RoHS conformity: TBC — exact-model evidence required. A logo or family-page claim is not qualification evidence.

Product identification and verified configuration

How the 80/20 ratio maps to 17 outputs

80/20 is the two-group ratio, not the number of output ports. On the photographed unit, one path is marked 80%, while sixteen paths are each marked 1.25%. Sixteen times 1.25% equals the remaining 20% nominal allocation.

Do not order or label the unit as simply “1×17 PLC.” The RFQ, drawing, product label, port map and purchase order should all carry the complete 80/1.25×16 ratio string.

Measured optical results for the photographed sample

The following values were transcribed from the supplied Final Test Report for serial 2024095454, dated 2024-09-28. The report states that data were measured at center wavelength. Engineering must confirm the test method, instrument, connector boundary and transcription before publication.

For this sample, the tap-path IL spans 19.59–19.89 dB at 1310 nm and 19.58–19.89 dB at 1550 nm. Use the approved maximum limits for the ordered build—not these sample minima/maxima—when closing a route budget. Obtain the report that matches the delivered serial number for acceptance.

Application and compatibility conditions

This configuration may fit a cascaded or tap-based passive optical distribution design when one route must retain a larger nominal power share and sixteen lower-power routes serve local branches. Suitability is conditional on the complete link budget, the active equipment limits, wavelength plan, connector/splice losses, fiber distance, engineering margin and every splitter stage.

Before approval:

1. Define which physical output is the 80% path and verify the label sequence.
2. Calculate every route, including the highest-loss tap, connectors, splices, fiber and engineering margin.
3. Confirm that the host enclosure accepts the current cassette drawing, pigtail-exit direction, service slack and connector-routing space.
4. Confirm SC/APC throughout the mating path. Do not mate APC and UPC interfaces.
5. Match the quoted model, drawing revision, product label, purchase order and report.

For topology selection and general unbalanced-splitter planning, use the site’s dedicated guide rather than expanding this SKU page into a broad tutorial. For package-family selection, see the cassette PLC splitter range and PLC splitter guide and products.

If the design calls for the published 70/30 steel-tube configuration instead, review the 1×17 70/30 uneven PLC splitter family and do not substitute its optical values for this 80/20 cassette build.

When this product is not a fit

• The design needs 17 equal-power outputs.
• The design specifies 70/30, 75/25 or another ratio instead of 80/20.
• The available enclosure space has not been checked against an approved drawing.
• The network requires UPC interfaces, a different connector family, or an unterminated splice-in module.
• The link budget cannot accommodate the worst approved tap-path loss plus the rest of the route.
• The project requires environmental, GR, RoHS or other compliance evidence that has not been supplied for the exact model and revision.
• The buyer is still deciding between PLC and FBT technology or among topology options; that decision belongs in the relevant selection guide, not in an exact-SKU substitution.

Test and document package to request

The release package for an order should identify the model and revision and, where applicable, include:

• controlled product datasheet;
• current dimensional drawing and pigtail-exit orientation;
• approved port map and label convention;
• production optical limits and test conditions;
• serial-matched IL/PDL report at the agreed wavelengths;
• requested material or compliance evidence for the exact model and scope;
• packing/label requirements and the agreed inspection plan.

The supplied photograph is evidence for one sample. It must not be presented as a blanket certificate or as proof that every future unit will reproduce the same readings.

RFQ checklist

Send the following in one request:

• quantity and project/location reference;
• commercial SKU, if already approved;
• exact configuration: 1×17, 80/1.25×16;
• SC/APC connector quantity and mating-interface requirements;
• fiber grade requirement; do not assume A1 or A2 when the document only states G657A;
• 3.0 mm pigtail construction and 3 m length, or the requested alternatives;
• available cassette space, mounting method and routing clearance;
• physical port-label sequence and which path continues downstream;
• route loss budget and required production maximums;
• required datasheet, drawing, test report, compliance and packing documents;
• target delivery date and destination for quotation.
