LC multimode pigtails are typically 900 µm tight-buffered fibers with LC UPC connectors, low insertion loss, and high return loss, suitable for splicing and high-density network applications.

Fiber and Connector Details

LC multimode pigtails are available in OM3 and OM4 multimode fibers with a 50/125 µm core/cladding configuration . They are terminated on one end with a high-grade LC UPC connector, while the other end is open for fusion or mechanical splicing . The connectors are designed for precision alignment to ensure minimal signal loss and stable connections .

Cable Construction

The fiber is typically 900 µm tight-buffered, providing flexibility and protection for indoor installations . The pigtail cable diameter is usually 0.9 mm, which is ideal for high-density splice applications in patch panels, ODFs, and distribution boxes . Jackets can be LSZH (Low Smoke Zero Halogen) for safety in indoor environments .

Optical Performance

• Insertion Loss: ≤0.25 dB for standard multimode, ≤0.15 dB for low-loss variants .
• Return Loss: >26 dB for multimode LC UPC connectors .
• Durability: Connector mating cycles exceed 500 matings .
• Pull Force: 5 N ± 0.5 N per IEC 61300-2-44 . These specifications ensure minimal attenuation, reliable data transmission, and low reflection, which are critical for high-speed networks .

Applications

LC multimode pigtails are widely used in:

• Data centers and LAN/WAN networks
• FTTH/FTTX deployments
• CATV, PON, WDM/DWDM systems
• Fiber distribution frames, subscriber sockets, and patch panels

Packaging and Traceability

Pigtails are typically individually packaged with part numbers, descriptions, optical performance data, and barcodes or QR codes for traceability . Each pigtail may include a flag label indicating fiber type and serial number, linking to factory test data.

Lengths and Variants

Common lengths range from 1 m to 5 m, with options for simplex, duplex, or quad configurations . Custom lengths and connector types are often available as make-to-order products . These specifications make LC multimode pigtails a reliable and flexible solution for high-performance fiber optic networks.
