FIBCONET has manufactured planar lightwave circuit (PLC) splitters in China since 2008. Our automated lines produce up to 500,000 PLC splitters per month across four package families — from mini steel-tube types used inside FTTH drop closures to cassette plug-in modules deployed in operator central offices.
Every splitter we ship is 100% оруулах алдагдлыг шалгасан on the production line, then verified through high-and-low temperature cycling before packaging. Chips come from a controlled dual supply chain combining domestic Chinese sources (Шижиа, Lixin) and Japanese/Korean options (Worriro, IPP) — so we match the cost, lead time and performance profile your project actually needs.
Below are the four PLC splitter families currently shipping to FTTH operators, ODN integrators and telecom distributors across Russia, Латин Америк, Southeast Asia and the Middle East.

A PLC (хавтгай гэрлийн долгионы хэлхээ) splitter is a passive optical device that divides one incoming optical signal evenly across multiple outputs, without needing power. In a GPON or XG-PON network, PLC splitters sit between the OLT in the central office and up to 64 захиалагчид, forming the “point-to-multipoint” architecture that makes fibre-to-the-home affordable.
| PLC задлагч | FBT задлагч | |
|---|---|---|
| Технологи | Planar waveguide chip + fibre array | Two fibres fused and tapered together |
| Split ratios | Powers of 2 (1×2 to 1×64), plus custom uneven ratios via chip design | Any ratio: 50/50, 70/30, 90/10, 5/95, 7/93, 12/88 |
| Долгионы урт | 1260–1650 nm broadband | Wavelength sensitive; specify 1310 / 1490 / 1550 nm |
| IL uniformity | Very consistent across all outputs | Varies with ratio; asymmetric ratios diverge |
| Cost at high split counts | Lower per output above 1×8 | Uneconomic above 1×4 |
| Хамгийн тохиромжтой | FTTH, GPON, XG-PON, dark-fibre distribution | Monitoring taps, CATV, non-standard ratios |
If you need standard 1×N distribution above 1×4, choose PLC. For asymmetric or non-power-of-2 ratios with few ports, choose FBT.
| Split ratio | Max IL (no connector) | Max IL (with connector, +0.3 дБ) | Typical network use |
|---|---|---|---|
| 1×2 | ≤ 4.0 дБ | ≤ 4.3 дБ | First-level split, dual-feed protection |
| 1×4 | ≤ 7.3 дБ | ≤ 7.6 дБ | Small MDU, first-stage aggregation |
| 1×8 | ≤ 10.5 дБ | ≤ 10.8 дБ | Second-stage FTTH distribution |

Note on insertion loss. Our patch-cord line achieves connector IL down to 0.1 дБ. This value applies to the connector alone and does not replace the PLC splitter loss budget. PLC IL is governed by the split ratio (see table above), plus a 0.2–0.3 dB connector allowance when connectors are attached.

FIBCONET began as a PLC splitter factory in 1994, six years before the first commercial GPON deployment. That head start let us build the supply-chain relationships and in-house tooling — housing moulds, alignment jigs, potting recipes — that most fibre passives vendors still buy in from third parties.
Combined monthly output across all PLC package types reaches approximately 1,000,000 units per month, on automated alignment lines where a single operator runs two machines in parallel.
The PLC chip drives 60–70% of the finished splitter’s optical performance. We keep two supply channels active in parallel: domestic chips (Шижиа, Lixin) as our default choice for cost, lead time and production availability — current-generation Shijia yield matches import quality — and imported chips (Worriro Japan, IPP Korea) for customers who specify origin or the tightest IL uniformity. Because we also hold contract positions upstream in fibre array (FA) and ferrule supply, our IL uniformity holds across batches without input-geometry drift.

Third-party test reports (electronic, stamped) available on request.

Standard-ratio cassette and box PLC splitters start from as few as 2 units — sample and trial orders are welcome. Mini and ABS box regular ratios ship from stock. Long-term partners can negotiate consignment or blanket terms. Silk-screen branded steel tubes require an MOQ of 1,000 pieces at no extra cost.
Regular ratios in standard packages are held in stock and ship within days. For a 5,000-piece 1×8 mini PLC order the typical lead time is around 20 days from PO, including approximately one week for raw material staging. Urgent orders can be prioritized on the production schedule; please flag urgency at RFQ stage.
Тиймээ. All uneven ratios including 1:3, 1:9, 2:8, 3:7 болон 5:95 дэмжиж байна, along with 2×N configurations. Insertion loss and uniformity meet industry standards; send us the required ratio, pigtail length and connector type and we will confirm specification, price and lead time.
Our PLC splitters are designed and tested to match the reliability methodology defined in Telcordia GR-1209 (passive branching components) and GR-1221 (reliability qualification). Full test reports from accredited third-party labs can be arranged for project bids.
Тиймээ. Бид таны уран бүтээлд зориулан захиалгат өнгөт хайрцаг үйлдвэрлэдэг, гадна хайрцагны лого, private-label stickers, техникийн хуудасны оруулга болон брэндийн гарын авлага. Full OEM/ODM support is standard.
Стандарт үйлдвэрийн баталгаат хугацаа 1 year against manufacturing defect. Design service life is 10 years or longer for mini PLC and 25 years or longer for cassette / box PLC, based on our accelerated ageing test data.
We default to G.657.A1 (10 мм хамгийн бага гулзайлтын радиус) rather than G.652.D (15 мм хамгийн бага гулзайлтын радиус), because the tight coiling inside splitter housings will cause additional loss or even fibre breakage with G.652.D. G.657.A2 (7.5 мм хамгийн бага гулзайлтын радиус) is available for the most compact form factors or drop-cable integration.
Тиймээ. Insertion loss test videos, optional 3D end-face inspection videos and stamped third-party test reports are available on request. Video content can be customized to buyer inspection protocols.
Тиймээ. We currently ship to operators, integrators and distributors across all four regions. LGX modules with the Russia-market mould are a stocked variant. Please advise Incoterms and destination port at RFQ stage — DDP feasibility can be evaluated for selected destinations.
