Pigtail LANBERG SM LC/UPC Semi-Tight 9/125 G657A1 12x2m multicolor

Fiber optic terminations in tight spaces often suffer from bend losses and connector mismatch. This 12-fiber pigtail bundle solves that by providing factory-terminated LC/UPC connectors on bend-insensitive G.657.A1 single-mode fiber, each with a 2-meter semi-tight buffered tail. Ideal for splicing into distribution frames, splice closures, or patch panels where space is limited and reliability is critical.

Who is it for

Network installers and data center technicians working on FTTH, LAN backbones, or telecom infrastructure. If you need to splice multiple fibers quickly without field connectorization, this pigtail set streamlines the process and ensures consistent optical performance.

Main features

• 12 individual pigtails with LC/UPC connectors, each 2 meters long
• Bend-insensitive single-mode fiber (ITU-T G.657.A1) with 9/125 µm core/cladding

• Color-coded per TIA/EIA-598-C for quick identification
• Low insertion loss (≤0.3 dB) and high return loss (≥50 dB)
• LSZH jacket material for safety in enclosed spaces
• RoHS and CE compliant

Tips

When splicing these pigtails, use a fusion splicer with a V-groove alignment for best results. The semi-tight buffer strips cleanly, but avoid excessive bending near the connector boot. For outdoor installations, protect the pigtail splices inside a weatherproof enclosure.
