Single-Mode Fiber Pigtail (1 Meter, LC Connector)

　　The single-mode fiber pigtail (1 meter, LC connector) is a specialized, short-length fiber-optic component designed for precise signal termination in high-performance networks. Unlike patch cords (which have connectors on both ends), a pigtail features a single connector (LC, in this case) on one end and a bare, unterminated fiber on the other—this design allows it to be fusion-spliced or mechanically connected to longer fiber cables, enabling seamless integration into single-mode networks. The 1-meter length is ideal for short-range terminations, such as connecting a single-mode transceiver to a fiber distribution panel (FDP) in a data center rack or linking a telecom closet’s patch panel to a local switch, where minimal cable slack reduces clutter and simplifies management.

　　At its core, this pigtail uses 9/125um single-mode fiber, characterized by a narrow 9μm glass core that transmits a single light beam. This design minimizes modal dispersion, enabling it to support ultra-long transmission distances (up to 100 km+ at wavelengths like 1310nm/1550nm) and high data rates, including 10 Gbps (10GBASE-LR), 40 Gbps (40GBASE-LR4), and 100 Gbps (100GBASE-LR4)—even in its compact 1-meter form, it retains single-mode’s immunity to electromagnetic interference (EMI) and radio frequency interference (RFI), a critical advantage over copper in industrial or high-voltage environments.

　　The LC connector is a key feature of this pigtail. As a small-form-factor (SFF) interface, it is half the size of traditional SC connectors, making it perfect for high-density setups like data center racks or telecom equipment where space is limited. It uses a push-pull latching mechanism that ensures secure, low-loss connections (<0.3dB insertion loss) and easy installation—essential for reducing downtime during network maintenance. The bare fiber end is typically coated with a protective buffer (250μm or 900μm) to prevent damage during splicing, and the pigtail’s jacket (usually LSZH or PVC) is durable enough to resist abrasion in rack environments.

　　Compliant with international standards like TIA/EIA-568-C.3 and IEC 61754, this single-mode LC pigtail guarantees compatibility with all single-mode LC-enabled hardware, from transceivers to patch panels. It is often color-coded (yellow, the standard for single-mode) for easy identification in mixed-fiber setups. For network technicians needing precise, short-range termination of single-mode fiber, the 1-meter LC pigtail offers reliability, compactness, and high performance—critical for maintaining signal integrity in long-distance-capable networks.
