How to identify fiber optic pigtail models

A fiber optic pigtail model number encodes its length, connector type, fiber type, diameter, termination, and color, typically following a standardized manufacturer coding system.

Understanding Pigtail Part Numbers

Most manufacturers, such as Prysmian, use a structured part number system to identify pigtails. A typical part number is 18 digits long and includes the following elements: Prefix: Usually "PIG" to indicate a pigtail. Length Code: A three-digit number representing the pigtail length in meters (e.g., 005 for 5 meters).

Connector Type: A single letter code representing the connector (e.g., SC, LC, FC, ST, E2000). Fiber Type: A single letter code for the fiber type (e.g., G657A1, OS2, OM4). Fiber Diameter: Two digits indicating the fiber diameter in millimeters (e.g., 09 for 0.

9 mm). Termination Type: A code specifying simplex or multi-fiber termination.

Color/

Quantity Code: A single letter representing the color and number of pigtails in a set, often following TIA/EIA-598-A color standards for multi-fiber bundles. For example, a part number like PIG-005-S-G-09-S-B could represent a 5-meter SC/APC connector, G657A1 fiber, 0. 9 mm diameter, simplex, blue color.

Identifying Key Features

Connector Type: Examine the factory-terminated end. Common types include LC, SC, ST, FC, E2000, and MT-RJ. Each has a distinct shape and locking mechanism.

Fiber Type: Check the fiber jacket color and labeling. Singlemode fibers (OS1/OS2) are usually yellow, while multimode fibers (OM1–OM5) have orange, aqua, or violet jackets. Length and Diameter: Measure the pigtail length and check the buffer diameter, typically 0.

9 mm for tight-buffered pigtails. Termination: Determine if the pigtail is simplex (single fiber) or multi-fiber (ribbon or bundle). Multi-fiber pigtails are color-coded for easy identification.

Manufacturer Datasheets: Refer to the manufacturer's datasheet or catalog, which maps the part number to all specifications, including insertion loss, return loss, and environmental ratings.

Practical Tips

Visual Inspection: Compare the connector and fiber color to standard charts. Label Check: Many pigtails have printed part numbers on the jacket. Splice Tray or Panel Reference: If installed, the pigtail may be labeled in the ODF or patch panel.

Consult Manufacturer: If the part number is unclear, the datasheet or customer support can decode it fully. By combining visual inspection, measurement, and part number decoding, you can accurately identify the model number and specifications of any fiber optic pigtail.
