The short answer

Included in the quotation
- Port count, connector polish and power configuration

- Export packing, HS code and Incoterm
A patch cord is the shortest and most replaced part of the ODN. It connects the OLT to the ODF, the ODF to the splitter, the splitter to the ONU. A low-loss cord is not enough: the connector polish must match the adapter, the fibre type must tolerate the bend, and the length must fit the route with a service loop.
The range covers simplex and duplex patch cords in SC/UPC, SC/APC, LC/UPC and LC/APC, in G.657A2 or G.652D, with 1, 2 or 3 m standard lengths. Pigtails are available for splicing, and MPO-to-SC/LC breakout cords for high-density panels. Copper Cat5e/Cat6 patch cords are available for the PoE edge. Each assembly is tested for insertion loss and return loss; the batch data travels with the order.
The most common field failure is a polish mismatch: a UPC cord in an APC adapter, or a dirty connector. Keep one polish type across the ODN, or use a hybrid cord at one point and label it. Clean and inspect every connector before measuring; a dirty SC connector can add 1–3 dB and look like a splitter problem.
Configuration table
The numbers that decide the fit.
Values are from the model datasheet. Where a value is model-dependent, the table says so instead of guessing.
| Type | Connector | Fiber | Length | Typical use |
|---|---|---|---|---|
| Patch cord | SC/LC, UPC/APC | G.657A2 / G.652D | 1 / 2 / 3 m | OLT / ODF / ONU |
| Pigtail | SC/LC | G.657A2 | 1 / 2 m | Splicing |
| MPO breakout | MPO to SC/LC | OM3/OM4 or SM | Custom | High-density panel |
| Adapter | SC/LC | — | — | ODF / panel |
| Copper patch cord | RJ45 Cat5e/Cat6 | Copper | 1 / 2 / 3 m | PoE edge |
Insertion loss and return loss are batch-tested; the exact values and tolerances are confirmed on the test report.
Engineering features
What changes on site.
Polish matching
SC/UPC or SC/APC to match the adapter and splitter; a hybrid cord is the only safe way to change polish.
Bend-insensitive
G.657A2 tolerates the tight bends behind a patch panel or a wall box.
Test data
Insertion loss and return loss are measured per assembly; the batch data is supplied with the order.
Labels
Label both ends with the port and device name; the as-built label saves the next fault find.
Simplex / duplex
Simplex for a single PON port; duplex or MPO breakout for high-density panels.
Standard lengths
1, 2 and 3 m cover most cabinet and ONU routes; custom lengths are quoted for projects.
Selection guide
Which configuration fits which site.
Start from the site, not from the model. The table is a starting point; the final check is the optical and power budget.
| Route | Recommended | Note |
|---|---|---|
| OLT to ODF | SC/UPC simplex, 2–3 m | Match the OLT connector |
| ODF to splitter | SC/UPC simplex | Keep the same polish |
| CATV overlay | SC/APC | ≥60 dB return loss |
| High-density panel | LC or MPO breakout | Confirm the panel interface |
| PoE edge | Cat5e/Cat6 copper | Keep under 100 m |
Measure the route with the service loop; a 2 m cord is often too short for a cabinet with a sliding tray.

Patch Cords, Pigtails & Adapters: questions before the order.
If your question is not here, send the site details and we will answer with the calculation, not a brochure.
Ask an engineerUPC or APC?
SC/UPC for data PON; SC/APC for CATV and long spans. A UPC cord in an APC adapter has high loss and reflection; use a hybrid cord at one point if needed.
What is the insertion loss?
A quality patch cord is typically ≤0.3 dB per mated pair; the exact value is on the test report. A dirty connector can add 1–3 dB.
Can I use a standard patch cord for PoF?
No. PoF needs a hybrid cable with a copper pair; a standard patch cord has no power conductors.
Do you supply custom lengths?
Yes for project quantities. The length, connector, polish and labelling are confirmed on the quotation.
How do I clean a connector?
Use a one-click cleaner and inspect with a scope. Clean both sides of the adapter; a dry wipe is not a substitute for inspection.
Are the cords tested?
Yes. Insertion loss and return loss are measured per assembly, and the batch data is supplied with the order.
Next step
Need a Patch Cords, Pigtails & Adapters configuration checked?
Send the endpoint count, the longest run, the power condition and the destination. We reply with the configuration, the optical/power budget and the quotation assumptions.
No obligation. The plan states its assumptions so your engineer can check it.
