The BWN-PLC-MMST-2X8-SC-APC is a 2×8 PLC splitter in a mini steel-tube package: two inputs in, eight outputs out, each port a 0.9mm pigtail with an SC/APC connector. The 60×12×4mm mini-module is built for fusion-splice environments — splice closures, joint boxes, distribution boxes — where the chip needs protection but a boxed module will not fit.
This configuration suits FTTH and PON builds that splice splitters straight into the ODN cable plant instead of patching them into a frame. The second input adds what a 1×8 cannot: a redundant OLT feed, a second service such as 1550nm RF video, or a spare path left dark. For other mini steel-tube ratios, see the blockless mini PLC splitter category; for the concept level, the fiber optic splitter overview.

Values are the 2×8 column of the 2×N specification table on this page; the boxed ABS module version measures 100×80×10mm.
This model ships with SC/APC connectors on 0.9mm G657A pigtails. The 8-degree endface directs reflections into the cladding rather than back to the source — one reason the unit holds a 55dB return loss, and the polish most PON and CATV networks specify. UPC, LC, and ST options are available on request.
G657A fiber is the default because pigtails are coiled inside closure trays, where the tray sets the bend radius. The tube protects the bare PLC device (50×4×4mm) and fan-out point; pigtails are fusion-spliced to the distribution cable and secured with splice sleeves in the tray. The 1260–1650nm window passes GPON, XGS-PON, and 1550nm RF video on the same plant.

1. Match the package to the installation point.
| Installation point | Package that fits |
|---|---|
| Splice closure / joint box (fusion-spliced) | Steel tube mini module — this page |
| Splice tray in a cabinet or wall box | ABS box module (100×80×10mm for 2×8) |
| ODF / 19-inch rack slot | LGX cassette or rack-mount chassis |
| Plug-and-play drop terminal | Cassette-type splitter with adapters |
At 60×12×4mm the tube is about 1/28 the volume of the boxed module; the trade-off is no adapters — every port must be fusion-spliced.
2. Need the second input? Choose 2×8 for a redundant feed, a second service wavelength, or a spare path; otherwise a 1×8 mini module is smaller (60×7×4mm) and 0.8dB lower (10.2dB vs 11.0dB, P grade).
3. Pick polish and pigtail. APC for PON and CATV plant where return loss matters (this model: 55dB); UPC only where mating hardware is UPC throughout. 0.9mm pigtails route in tray channels and take standard splice sleeves; choose 2.0/3.0mm jackets where leads leave the tray. Standard length 1m, custom on request.
4. Check the loss budget. The 11.0dB stage plus connector and splice margin must fit your PON class budget — verify on the splitter loss chart (1×2 to 1×64).

A 2×8 PLC splitter takes two input fibers and splits the signal from each input evenly across eight outputs. The second input carries a redundant feed, a second service such as 1550nm RF video, or stays dark as a spare — it does not need to be connected on day one. This model outputs on 0.9mm pigtails with SC/APC connectors; insertion loss is 11.0dB max, uniformity 1.2dB.
Match the package to the installation point. Steel tube (60×12×4mm) goes inside fusion splice closures and joint boxes where every port is spliced. ABS box modules (100×80×10mm for 2×8) sit in cabinet or wall-box trays. Cassettes and LGX modules plug into ODF frames and rack slots.
It is the smallest protected package. The bare device is 50×4×4mm; the tube adds protection and strain relief for the fan-out while keeping the assembly at 60×12×4mm — small enough to lie in a standard splice tray. A boxed module eats several splice-sleeve slots.
Route pigtails through the tray’s fiber channels, keep coils within the bend-radius guides (G657A tolerates tight coiling), and splice each output to its distribution fiber with a heat-shrink sleeve in the tray holder. Where leads exit exposed, order 2.0/3.0mm jackets.
11.0dB maximum per the 2×N specification table on this page, with 1.2dB uniformity, 0.3dB PDL, and 0.5dB wavelength dependent loss across 1260–1650nm. A 1×8 runs lower at 10.2dB (P grade), so specify 2×8 only when the second input earns its extra 0.8dB.
SC/APC for PON and CATV plant: the 8-degree endface supports this model’s 55dB return loss, which OLTs and RF video links require. UPC only when mating hardware is UPC throughout — never mate APC to UPC; the endfaces do not seat and can be damaged.
