Pigtail specifications models and dimensions

Pigtails are specialized connectors or flexible hoses used in fiber optic networks and gas systems, available in various lengths, materials, and connector types to meet specific application requirements.

Fiber Optic Pigtails

Applications: Fiber optic pigtails are used in FTTx, FTTH, data centers, CATV, PON, WDM/DWDM, ATM, and SONET networks for fusion splicing and connectivity inside patch panels, closures, and optical distribution frames . Materials and Construction:

• Standard fiber diameter: 900 micron tight buffer; ruggedized options: 1.6 mm, 2 mm, 3 mm .
• Fiber types: G657A1 singlemode, multimode options available .
• Connectors: SC, SC/APC, LC, LC/APC, and other polished connectors with ceramic ferrules .
• Pull force: 5 N ± 0.5 (1.12 lb.) per IEC 61300-2-44.
• Connector durability: >500 matings for both multimode and single-mode . Dimensions and Lengths:
• Standard lengths: 1, 2, or 3 meters; longer lengths available on request .
• Ordering increments: 0.5 m up to 10 m, above 10 m in 1 m increments .
• Packaging: Individually labeled with fiber type, serial number, and QR code for traceability . Performance:
• Insertion loss: ≤0.25 dB
• Return loss: >26 dB for multimode, >50 dB for single-mode; APC connectors ≥60 dB .
• Temperature range: Operating -20 °C to +70 °C, Storage -40 °C to +75 °C . Color Coding: Standard colors for fiber types: white (OS2, OM1, OM3, OM4), lime (OM5), with sets of 6 or 12 colors for identification .

Gas System Pigtails

Applications: Flexible hoses for high-pressure gas systems including specialty gases like hydrogen, helium, propane, and MAPP gas . Materials and Construction:

• Stainless steel, PTFE-lined with stainless steel braid, or armor-cased for kink and whip protection .
• End fittings: CGA connections, some with integrated check valves to prevent reverse flow .
• Tube types: 1/4" x .049 wall stainless steel, type 316 SS . Dimensions and Pressure Ratings:
• Lengths: Customizable, typically up to several meters .
• Pressure: Rated up to 3000 PSIG, with safety factors of 4:1 or 5:1 for normal applications .
• Special configurations available for impulse, shock, or high-pressure applications . Usage Notes:
• Do not apply heat to pigtails.
• Hydrogen and helium require specific fittings and materials .

Ordering and Customization

• Fiber optic pigtails can be custom-ordered for length, fiber type, connector type, and color .
• Gas pigtails can be configured for specific gases, pressures, and fittings .
• Manufacturers provide datasheets and part number systems to specify length, connector, fiber type, diameter, termination, and color . Summary: Pigtails are versatile components designed for precise connectivity in fiber optic networks or safe gas delivery. They vary in length, material, connector type, and performance, with strict adherence to standards like IEC 61300 and Telcordia GR326 for fiber optics, and CGA compliance for gas systems .
