The round-headed pigtail is an FC series fiber optic connector

The round-headed pigtail is an FC series fiber optic pigtail featuring a spherical ferrule for improved mating performance and a threaded coupling for secure connection.OverviewAn FC series fiber optic pigtail is a short length of optical fiber with a factory-terminated FC connector on one end and a bare fiber on the other for splicing into a fiber optic network . Unlike patch cords, which have connectors on both ends, pigtails are designed for fusion or mechanical splicing to bulk fiber cables, providing low-loss, high-reliability connections .FC Connector FeaturesThe FC (Ferrule Connector) series is characterized by:Threaded coupling mechanism: Ensures a secure connection that resists vibration, making it suitable for high-vibration environments .Metal sleeve and ferrule: The connector uses a 2.5 mm ceramic ferrule housed in a plated nickel body, providing precise fiber alignment and high optical performance .Round-headed ferrule: The spherical ferrule design improves the mating surface, reducing Fresnel reflection and enhancing insertion loss and return loss performance .Tuning capability: Some FC connectors allow rotation of the ferrule to optimize insertion loss by aligning fiber cores precisely .Pigtail SpecificationsFC series pigtails typically have:Cable diameter: 0.9 mmFiber types: Single-mode (SM), Multi-mode (MM), OM3, OM4Polish types: UPC/PC and APCLength: Standard 1.5 meters, customizable upon request ApplicationsFC series pigtails are widely used in:Optical Distribution Frames (ODF)Telecommunication networksHigh-precision laboratory setupsBroadcasting and CATV systems (especially APC variants for angled polishing) The round-headed FC pigtail is particularly valued for its ease of operation, high stability, and low insertion loss, making it suitable for both field installations and high-performance network environments .SummaryIn essence, the round-headed FC series fiber optic pigtail combines the precision of a factory-terminated connector with the flexibility of field splicing, featuring a spherical ferrule and threaded coupling that enhance optical performance and reliability in demanding applications .
