A patch cord line schedule is a table with one row for each distinct patch cord configuration: connectors, polish, fiber, cable, length, labels, packing and quantity. It turns a vague request such as "LC patch cords, various lengths" into something a supplier can quote and build without guessing, and it gives both sides a reference for revisions, samples and delivery checks. This guide lists the columns to include, shows a worked LC/SC example and explains how to keep the schedule under revision control.

A line changes whenever any physical property changes: a different connector, polish, fiber grade, diameter, jacket, color, length, label or packing rule. Writing each as its own row has three effects. Quotes from different suppliers can be compared line by line. Production builds exactly what is listed. And at delivery, cartons, labels and test records can be matched to the row they belong to.
| Column | What to write |
|---|---|
| Line ID | Your SKU or a stable line number, reused in every revision |
| End A / End B | LC, SC, FC, ST or MTP/MPO, simplex or duplex |
| Polish | UPC or APC for each end |
| Fiber | OS2, OM3, OM4, OM5, or a fiber standard such as G.657.A1 |
| Cable | Diameter, jacket material or rating, color |
| Length | One length per row, with tolerance if critical |
| Polarity | A-to-B for duplex unless your design says otherwise |
| Label | Text, type (flag, wrap, heat-shrink) and position |
| Packing | Bag, coil size, carton grouping, carton marks |
| Quantity | Per row, not per family |
| Notes | Reference SKU, drawing or sample photo |
| Line | Configuration | Label and packing | Qty |
|---|---|---|---|
| PC-01 | LC/UPC–LC/UPC duplex, OM4, 2.0 mm LSZH aqua, 3 m | Buyer SKU flag label both ends, individual bag | 200 |
| PC-02 | SC/APC–SC/APC simplex, OS2 G.657.A1, 2.0 mm LSZH yellow, 5 m | Bag label with line ID, carton of 100 | 300 |
| PC-03 | LC/UPC–SC/UPC duplex, OS2, 2.0 mm LSZH yellow, 10 m | Heat-shrink label with port ID both ends | 80 |
| PC-04 | LC/APC–LC/APC duplex, OS2, 1.6 mm LSZH yellow, 1 m | Individual bag, mixed carton with PC-03 | 120 |
Each row can be quoted and built on its own. Note that PC-03 and PC-04 share a carton: packing rules that span rows belong in the notes of both rows.
For deeper packing and labeling rules, see the patch cord packing and label guide.
For a new configuration or a new supplier, approve a sample before volume production. Order one or two pieces per new row, check connectors, polish, length, labels and packing against the schedule, and test insertion and return loss on your own equipment. Record the approval against the row and the schedule revision. Later orders can then cite the approved row instead of repeating every detail, and any change to that row triggers a new sample.
FAQ
A table with one row per patch cord configuration, listing connectors, polish, fiber, cable, length, polarity, labels, packing and quantity.
Yes. Each length is a separate configuration with its own quantity, label and packing.
Any spreadsheet or CSV works. Keep one row per configuration and add a revision letter and date.
Send it with a photo and label of the sample, but still list the fields; SKUs differ between suppliers.
Line IDs are carried onto labels, test records and packing lists, so each delivered carton can be checked against its row.
Standards and public references describe definitions and industry practice; they are not Lumafyn product data. Optical values, MOQ and lead time for your order are confirmed in your quotation and test records.
