FBT-1×2-SM-0.9-SCAPC-7030
FBT Splitter
1×2 Singlemode FBT Splitter, 70/30, SC/APC, 0.9 mm
Model FBT-1×2-SM-0.9-SCAPC-7030 is a connectorized 1×2 fused biconical taper coupler for an unequal 70/30 optical-power split. The supplied product photos show three green SC/APC connectors, 0.9 mm leads and a package label identifying a 70/30 sample. Confirm which output is the 70% through path, which is the 30% tap, the required wavelength window, lead length and optical acceptance limits before ordering.

What this exact configuration is for
Use this SKU when one singlemode input must feed two SC/APC-terminated paths with different nominal power shares. It is a configuration-specific product page—not the owner for general FBT selection, FBT-versus-PLC comparison or universal link-budget guidance.
Typical project roles may include a through path plus a lower-power tap for distribution, monitoring or test access. Suitability depends on the approved optical budget, equipment limits, wavelength plan and port assignment. A 70/30 label alone does not establish which physical lead is the 70% path.

| Connector | SC/APC, three terminated leads visible | Observed in supplied photos |
| Lead protection | 0.9 mm | Supported by supplied label; construction/material remains TBC |
| Sample lead length | 0.5 m appears on the photographed label | Observed for the photographed sample only |
| Order lead length | TBC — source required; state on PO | Do not assume 1 m from family practice |
| Working window | TBC — source required | Draft states 1310/1550 nm; attach applicable datasheet/test report |
| Package dimensions/material | TBC — drawing required | Photos do not establish approved dimensions/material |
| Environmental limits | TBC — source required | Not supplied |
| Compliance/certification | TBC — model-specific evidence required | Not supplied |
Sample optical record — hold until the report is attached
The source Markdown transcribes the following sample values. They are retained for review but are not release-ready product specifications because the original test report, serial/lot linkage, method, instrument, calibration status and acceptance limits were not supplied.
| Wavelength | Port assignment | Nominal share | Transcribed actual share | Transcribed IL | Evidence status |
|---|---|---|---|---|---|
| 1310 nm | P1 | 70% | 69.98% | 1.62 dB | TBC — original report required |
| 1310 nm | P2 | 30% | 30.02% | 5.30 dB | TBC — original report required |
| 1550 nm | P1 | 70% | 69.57% | 1.68 dB | TBC — original report required |
| 1550 nm | P2 | 30% | 30.43% | 5.27 dB | TBC — original report required |
The source also states directivity ≥55 dB and excess-loss values of 0.07 dB at 1310 nm and 0.10 dB at 1550 nm. Keep these values on hold until the applicable report and limit definition are approved.
Technical-reference disclaimer: Transcribed sample figures and family reference ranges are provided for configuration review only. They are not guaranteed acceptance limits. Confirm the current model-specific datasheet, approved order specification and traceable test report before design approval or purchase.
How to confirm the correct 70/30 build
- Define the optical role of each output: identify the 70% through path and the 30% tap.
- State the required wavelengths and both minimum- and maximum-power conditions at the connected equipment.
- Confirm SC/APC at every mating interface; do not substitute UPC polish.
- State input and output lead lengths, label text and required port-color convention.
- Provide the host tray, closure or box space if package fit matters.
- Set acceptance limits for each path and request a report linked to the delivered lot or serial record.
When this SKU is not the right match
- Choose another connector-specific model if the mating interface is LC/UPC, SC/UPC, FC/APC or unterminated.
- Choose another ratio if the approved link budget does not require a 70% through path and 30% tap.
- Choose a PLC splitter when the architecture requires uniform division across a higher port count rather than a two-path unequal tap.
- Do not approve this SKU from a family table alone when wavelength, lead length, package dimensions or test limits differ.

For broader selection, compare the FBT splitter product range and the fiber optic splitter overview. Use the FBT versus PLC splitter guide for technology selection. If an equal, unterminated build is required instead, review the 1×2 50/50 bare FBT splitter.
RFQ checklist
Send the following so the configuration can be checked before quotation:
- Model or reference code
- Required 70/30 port assignment and lead-label convention

- Maximum insertion loss for both output paths
- Required return loss, directivity, PDL and excess-loss limits, where applicable
- Singlemode fiber grade
- SC/APC interface confirmation at input and both outputs
- Input/output lead lengths and 0.9 mm protection requirement
- Package dimensions or host-enclosure constraints
- Quantity, destination and requested schedule
- Required datasheet, drawing, sample record, lot report and compliance documents
Documents to request before approval
- Current model-specific datasheet
- Dimension/package drawing
- Port-assignment and label drawing
- Sample or lot-specific optical test report
- Connector end-face acceptance record, if required by the project
- Applicable compliance evidence matched to this exact configuration
FAQ
1×2 Singlemode FBT Splitter, 70/30, SC/APC, 0.9 mm FAQ
Does 70/30 identify the physical output leads?
No. The percentages state the nominal power shares, but the order record must identify which labeled physical output is the 70% path and which is the 30% path.
Do the stated insertion-loss values include the SC/APC connectors?
The supplied Markdown says the transcribed sample values include connectors. This remains TBC — original report required before publication or acceptance use.
Is this the same product as a 70/30 LC/UPC coupler?
No. The nominal ratio may match, but the connector family and polish do not. Keep SC/APC and LC/UPC as separate configurations and verify the mating interface.
Can I use the category’s typical 30/70 loss range as this SKU’s acceptance limit?
No. Category figures are reference ranges. Use the approved model datasheet and order-specific acceptance limits for this connectorized build.
What lead length is supplied?
The photographed sample label includes 0.5M. The source draft separately proposes 1 m as an order default. This conflict must be resolved; state every lead length on the quotation and PO.
Is the fiber G.652.D or SMF-28e?
The supplied label confirms singlemode, but the exact fiber grade is not legible or otherwise documented in the available source. Confirm it on the datasheet or BOM.
What should be checked in the optical budget?
Check both paths separately. Include the approved splitter loss, connector pairs, splices, route loss, equipment operating limits and engineering margin. Also check the high-power path against any receiver overload or minimum-loss constraint.
