12 Color SC APC Pigtails and Fiber Optic Pigtail Sets for ODF and FTTH

A 12 color SC APC pigtail set is twelve singlemode pigtails, each in one of the twelve standard fiber colors, with an SC connector polished at an 8° angle (APC) on one end and bare fiber on the other for fusion splicing in an ODF tray, splice closure or FTTH terminal box. Lumafyn quotes 12-color sets and single pigtails in SC/APC, SC/UPC, LC, FC and ST for ODF trays, terminal boxes, fiber cabinets and network installation projects.

Fiber optic pigtails, adapters and connectors for ODF and FTTH splicing

Product Overview

Fiber pigtails are used for fusion splicing and optical distribution. A pigtail is a short tight-buffered fiber with a factory-terminated connector on one end only; the bare end is spliced to the field cable, which gives a lower-loss, cleaner termination than field-polishing a connector. Lumafyn supports custom connector, fiber type, jacket color, length and packing requirements.

Typical Options

SC/APC, SC/UPC, LC/UPC, FC and ST connector options
Singlemode G652D, G657A1 and G657A2
0.9mm tight buffer and project-specific length
12-color pigtail sets for ODF and splice tray use

How a 12-Color Set Is Used

Strip the incoming cable or loose tube and identify the twelve fibers by color.
Fusion-splice pigtail 1 (blue) to fiber 1, and so on through fiber 12 (aqua), protecting each splice with a heat-shrink sleeve in the tray.
Route each pigtail to its adapter position and plug in the SC/APC connector.
Record the port map so fiber color, tray position and adapter number match.

Color Code

12 Color Pigtail Order and SC APC vs SC UPC

Write the color order into the RFQ. If your network uses a national code rather than TIA-598, attach it.

Buyer Checklist

What to Put on a Pigtail RFQ Line

Interface

Connector and polish that match the adapter, for example SC/APC simplex into an SC/APC adapter.

Fiber and buffer

G.652.D or G.657.A1/A2, 0.9 mm tight buffer unless the tray needs another size.

Set and color order

Single pigtails or 12-color sets, and which color sequence applies.

Length

Length per pigtail to suit the tray and routing; state the tolerance you need.

Testing

Request insertion loss, return loss and end-face inspection records if required; limits are confirmed in the quote.

Connected items

Adapters, splice sleeves, trays or ODF panels quoted on the same RFQ so interfaces match.

FAQ

12 Color SC APC Pigtail Questions

What is a 12 color SC APC pigtail used for?

It terminates the twelve fibers of a cable or tube in a splice tray: each pigtail is fusion-spliced to one incoming fiber and its SC/APC connector plugs into an adapter on the ODF or terminal box. The colors let the installer keep fiber order without extra labels.

What is the standard 12-fiber color order?

ANSI/TIA-598 lists blue, orange, green, brown, slate, white, red, black, yellow, violet, rose and aqua for fibers 1 to 12. Some operators, particularly in parts of Europe, use a national sequence instead, so state the order your network uses.

SC APC or SC UPC pigtails?

Match the adapter and network. SC/APC (green) is common in FTTH and PON because the 8° angle lowers reflection; SC/UPC (blue) is used where the equipment and panels are UPC. Never mix APC and UPC on the same adapter.

What fiber is used in singlemode pigtails?

Usually G.652.D, or bend-insensitive G.657.A1/A2 where pigtails are coiled tightly in trays and boxes. Multimode OM3/OM4 pigtails are also available on request.

Which length should I order?

Common lengths are 1 m, 1.5 m and 2 m in 0.9 mm tight buffer. Choose by tray size and routing path; a custom length can be quoted per line.
