12-core pigtail (single-mode/multi-mode) | Factory pre-terminated, low loss, suitable for ODF/data center fast splicing
12-core fiber bundle designed for efficient and fast splicing.
High-quality, low-loss fibers ensure optimal performance and signal integrity.
Available with various connector options (SC, LC, FC, ST, MTRJ) and fiber types (singlemode, multimode).
Factory-terminated for quick installation with minimal preparation time.
Low insertion loss and high return loss, ensuring reliable and long-lasting connections.
What is 12-core pigtail
Our 12-core fiber bundle pigtails provide high-density fiber optic connections for a wide range of applications. These pigtails are designed for fast and reliable splicing in telecom networks, data centers, and fiber optic systems. The bundle is factory terminated and ready for easy integration into fiber distribution frames (ODFs) and other network equipment.
Designed for high-density cabling and batch deployment scenarios, this 12-core pigtail supports single-mode (G652D/G657A) and multimode (OM1–OM4) fiber and offers a variety of termination options, including SC, LC, FC, ST, and MTRJ. Pre-terminated and fully inspected at the factory, it offers low insertion loss and excellent echo performance. On-site deployment requires only quick fusion splicing or docking, significantly reducing construction and cutover time. The compact and clearly labeled fiber bundles facilitate cable management and maintenance within ODFs, cabinets, and trays, making it widely applicable to fiber optic systems requiring stable and reliable performance, such as data center expansion, telecom backbones, and FTTH access.

12-Core Pigtail Installation Instructions
Prepare – Strip 30–40mm of the main cable jacket; strip the pigtail’s buffer tube to expose the 12 color-coded fibers.
Clean – Inspect and clean all connector ferrules with lint-free wipes and isopropyl alcohol.
Splice – Match fibers by color, cleave precisely, and fusion splice each core to the corresponding main cable fiber.
Secure – Organize splices in the tray/cassette, route with gentle bends (avoid sharp bends), and secure with cable ties.
Test – Verify insertion loss and return loss with an optical power meter and light source.
Safety: Wear safety glasses; work in a clean, dust-free environment.
