What is a Standard Pigtail?

A standard pigtail is a fiber optic cable assembly with a connector pre-installed on one end and a bare fiber on the other, designed for fusion splicing to the outgoing fiber of an ODF, splice closure, or terminal box. The connectorized end provides a reusable, plug-and-play interface to active equipment or patch panels, while the bare end is permanently joined to the distribution fiber using a fusion splicer. OMC's standard pigtails use 900µm tight-buffered fibers in 1 m to 3 m standard lengths, with the connector end factory polished and 100% tested for insertion loss, return loss, and end-face geometry. The unterminated end is precision cleaved to ensure low-loss fusion splicing in the field.

Connector Options and Optical Performance

Standard pigtails are available with all common connector types: SC, LC, FC, ST in both UPC and APC polish options, as well as E2000 and MU for specialized applications. Singlemode pigtails typically use G.652.D or G.657.A1 bend-insensitive fibers with insertion loss ≤0.2 dB (UPC) or ≤0.3 dB (APC) and return loss ≥50 dB or ≥60 dB respectively. Multimode pigtails use OM1, OM2, OM3, OM4, or OM5 fibers optimized for 850 nm VCSEL transmission. Each connector features a zirconia ceramic ferrule with concentricity within 1 µm, ensuring reliable mating with bulkhead adapters. Boot colors indicate fiber type per industry convention: beige for multimode, blue for SM UPC, green for SM APC, aqua for OM3/OM4.

Typical Use Cases in FTTH and ODF

Standard pigtails are deployed wherever a permanent, low-loss connection between an incoming distribution cable and active equipment is required. In FTTH networks, they terminate feeder cables at the splitter input ports or customer-side drop cables in building distribution boxes. In central office ODFs (Optical Distribution Frames), pigtails connect incoming feeder cables from the access network to the switch ports via the cross-connect field. Inside splice closures, they extend the spliced fibers to a connectorized interface for testing or drop cable termination. Cable TV head-ends use pigtails to terminate the optical input of EDFAs and transmitters, while enterprise networks deploy them at floor distributors to terminate horizontal backbone cables. Pigtails also serve as the input stage for PLC splitter packaging.

Fiber Types and Length Options

OMC offers pigtails in every common fiber type to match the deployment environment. For indoor FTTH, G.657.A1 or G.657.A2 bend-insensitive fibers are recommended to withstand tight routing in wall outlets and ONT enclosures. Standard single-mode G.652.D is used for outdoor plant and ODF applications. For data centers, OM3 or OM4 multimode fibers support 10G, 40G, and 100G Ethernet links. OM5 wideband multimode is available for emerging 400G SWDM4 deployments. Standard lengths range from 1 m to 3 m, with custom lengths available up to 10 m for specialized installations. Bundle configurations (6-fiber, 12-fiber ribbon pigtails) are available for high-density splice trays, using ribbon fibers for mass fusion splicing.

Ordering and Quality Assurance

To order OMC standard pigtails, specify the connector type and polish (e.g., SC/APC, LC/UPC), fiber mode (SM OS2, MM OM3/OM4/OM5), cable length, and quantity. Each pigtail is individually serialized and ships with a measured test report including insertion loss in dB, return loss in dB, and end-face geometry pass/fail status. OMC maintains a manufacturing capacity of 50,000 connectors per day to support large-scale FTTH rollouts. Bulk packaging options include 6-packs, 12-packs, or individual units with optional splice protection sleeves pre-loaded.
