FIBER PIGTAILS BUYING GUIDE
The Types and Connection Methods of Fiber Pigtails
Fiber pigtails, often referred to simply as pigtails, consist of one end with a connector and the other end with the exposed fiber optic cable. They serve the purpose of linking optical cables with optical transceivers, with the addition of couplers or jumpers if needed. Typically found within fiber optic terminal boxes, they connect to other fiber optic cable cores through fusion splicing, streamlining the installation and maintenance of cable systems.
The types of fiber pigtails
Fiber pigtails are typically categorized into single-mode and multi-mode variants. Single-mode pigtails operate at wavelengths of 1310nm and 1550nm, enabling transmission distances of 10km and 40km, respectively. Multi-mode pigtails, on the other hand, utilize a wavelength of 850nm with a transmission distance of 500m, suitable for short-distance connections. FS pigtails are crafted with precision ceramic ferrules, ensuring robustness and adherence to Telcordia and EIA/TIA standards.
Commonly employed in transmission systems, fiber pigtails come in five interfaces: LC, SC, ST, FC, and LSH. Their connectors share the same shape and color as their corresponding patch cords.
Aside from these standard types, there are also bundled and ribbon pigtails, both serving as branch able options. Bundled pigtails find utility in industrial projects, while ribbon pigtails are prevalent in extensive communication undertakings like telecommunications and mobile networks.
The connection methods of fiber pigtails
Fiber pigtails serve various interconnection and cross-connection roles in network access equipment, finding widespread application in optical fiber CATV networks, FTTH/FTTX setups, telecommunication networks, pre-terminated installations, optical fiber data transmission, and LAN/WAN networks. Typically integrated into fiber optic distribution frames, terminal boxes, and distribution frames, they facilitate connections with other fiber optic cable cores. Fiber pigtails employ two primary connection methods: mechanical splicing and fusion splicing.
1. Mechanical splicing of fiber pigtails involves stripping, cutting, cleaning, and then inserting the fibers and pigtails into a splice-matching tray for alignment, tangency, and locking.
2. Fusion splicing of fiber pigtails requires stripping the fibers and pigtails with a wire stripper, cleaning and wiping the bare fiber with alcohol cotton, cutting the optical fiber with a fiber cutter, and then fusing them using a fusion splicing tool under welding plate protection.
