This 1×2 mini PLC splitter with FC/APC connectors packs a 1×2 even split into a 60×7×4mm steel tube. It delivers 3.8/4.0dB insertion loss, 55dB return loss, and full 1260–1650nm coverage through 0.9mm G657A pigtails — built for splice closures, CATV nodes, and legacy FC panels.

The BWN-PLC-MMST is a 1×2 mini PLC splitter with FC/APC connectors in a 60×7×4mm steel tube. It divides one singlemode input into two even outputs across the full 1260–1650nm window, with 3.8/4.0dB insertion loss (P/S grade), 55dB return loss, and 0.9mm G657A pigtails.
This configuration suits buyers who need a connectorized 1×2 split that drops straight into a splice closure, distribution box, or CATV node housing. The steel tube protects the chip and pigtails during handling and tray routing — unlike bare-fiber splitters with exposed 250µm fibers. FC/APC fits plant where the threaded FC interface is already standard — legacy CATV, older ODFs, vibration-prone housings — because the screw-lock coupling stays seated. For other split counts in the same mini format, see the blockless mini PLC splitter category.

P/S lists two insertion-loss grades; state your grade when ordering.
FC/APC interface. FC connectors use a 2.5mm ceramic ferrule in a threaded coupling nut. Mating is slower than push-pull SC or LC, but the nut does not back off under vibration — why FC persists in CATV headends, optical nodes, test equipment, and older ODFs. The APC polish (8° endface) supports the 55dB return loss rating; never mate APC into UPC adapters, because the flat and angled endfaces cannot seat.
Fiber and pigtails. Standard fiber is G657A bend-insensitive singlemode; other types on request. The 0.9mm pigtails bend around tray corners without the stiffness of 2.0/3.0mm leads and fusion-splice to 250µm distribution fibers. Standard length is 1m per side; custom available.
Where it connects. The module sits inline between a distribution fiber and two output legs, inside closures, connection boxes, nodes, and small frames. For two-input, eight-output needs in the same format, see the 2×8 steel tube PLC splitter with SC/APC connectors.
1. Confirm the split count. Choose 1×2 when you need exactly two outputs — each added stage costs budget: 1×4 is 7.1/7.3dB, 1×8 is 10.2/10.5dB, against 3.8/4.0dB here. Check the total against the splitter loss chart (1×2 to 1×64) first.
2. Pick the package for the mounting point. A steel-tube mini module goes inside closures and connection boxes, fusion-spliced in. ABS boxes suit wall-mount points; cassette and LGX types suit panels and racks — compare formats in the PLC splitter category.
3. Match the connector to the plant. FC/APC for threaded-FC and vibration-prone housings; SC variants for SC panels. Keep one polish per link — APC mates with APC only.
4. Check the loss grade. The table lists 3.8dB and 4.0dB grades; on a tight GPON budget that 0.2dB can decide a marginal drop. State the grade when ordering.
5. Specify the pigtails. 0.9mm is standard for closure trays; confirm lead length (1m standard, custom available) so tails reach the splice organizer without excess slack.

Optical performance — insertion loss, return loss, polarization dependent loss, uniformity — is verified against the specification tables. Compliance with Telcordia GR-1209-CORE and GR-1221-CORE is stated per BWNFiber product documentation.
Standard: 1×2 split, FC/APC on all ports, G657A fiber, 0.9mm pigtails, 1m leads. Pigtail length, fiber type, and connector options can be customized.

This module is rated 3.8/4.0dB insertion loss (P/S grade) with 0.4dB uniformity between its two outputs — the lowest-loss split in the PLC family (1×4 is 7.1/7.3dB, 1×8 is 10.2/10.5dB). A 1×2 stage preserves the most optical budget on long PON drops.
Order FC/APC where threaded FC adapters are already installed — legacy CATV nodes, older ODFs, test benches — or where vibration could loosen a push-pull connector. The coupling nut screws on and stays seated. For SC-based panels, order the SC variant of the same module instead of adding hybrid adapters.
The mini module measures 60×7×4mm, built to sit inside splice trays in closures and connection boxes. Check your tray’s splitter slot against the 60mm length before ordering; the 0.9mm pigtails route to the tray’s splice organizer for fusion splicing.
0.9mm tight-buffered pigtails are standard for work inside closures: they bend around tray corners with little spring force and fusion-splice directly to 250µm distribution fibers. Jacketed 2.0/3.0mm leads suit exposed patching but are stiffer and take more space in crowded organizers.
Yes. The operating window is 1260–1650nm with 0.3dB wavelength dependent loss, so 1310nm upstream, 1490nm downstream, and 1550nm RF video wavelengths all pass through the same device. That full-window transmission is a PLC waveguide property, unlike FBT couplers built for specific wavelengths.
A bare fiber splitter ships the PLC chip with exposed 250µm fibers in a minimal package. This mini module encloses the chip in a steel shell with 0.9mm protected pigtails — better protection during handling and tray installation, at a slightly larger 60×7×4mm footprint.
Standard leads are 1m on the input and both outputs; custom lengths are available on request. Fiber type is G657A or customer-specified. For SC/APC, SC/UPC, or mixed connector sets, state it in your inquiry so the factory confirms the build before quotation.
