**Pigtail LC/UPC 12 colors OM4 0.9mm OFNR 3M, tight buffer** from **Red Cable Technology (RCT)** is a 12-fiber pigtail set made to terminate fiber optic cable by **fusion or mechanical splicing**. Each leg is terminated with an **LC/UPC connector** on **laser-optimized 50/125 multimode OM4** fiber, with **0.9mm tight-buffered** construction and an **OFNR-rated** jacket in a **3-meter** length. The 12-color coding keeps fibers easy to tell apart.
**Features & Specs:**
- 12 color-coded pigtail legs for fast fiber identification in high-density terminations
- LC/UPC connectors — small form factor (SFF) “little connector” with a 1.25mm ferrule, about half the size of SC; known for good performance and small size
- UPC (blue) polish with no angle — not exactly flat, with a slight curvature for better core alignment (UPC connectors are blue; APC connectors are green)
- Laser-optimized 50/125 µm multi-mode OM4 fiber with a 50µm core — a further improvement to OM3
- Supports 10 Gigabit Ethernet at lengths up to 550 meters and 100 Gigabit Ethernet at lengths up to 150 meters
- Laser-optimized multi-mode fiber (LOMMF) is designed for use with 850 nm VCSELs
- 0.9mm tight-buffered legs, 3M length, OFNR jacket rating; OM4’s suggested jacket color is aqua
- Tight-buffered construction uses 900µm buffered fibers with a two-layer coating — plastic first, waterproof acrylate second — so the core is never at risk of exposure the way loose-buffered fiber can be
- Fibers sit in dielectric FRP strength members under a rugged polyurethane outer jacket for superior environmental and mechanical protection
- Tight-buffered fiber counts run 1 to 144 fibers; 2, 6, 12, and 24 are most common, with 48, 96, and 144 available for specific applications
## On the Job
Terminates fiber optic cable by fusion or mechanical splicing — quality pigtail cable plus correct fusion splicing practice gives the best termination performance — typically installed in ODFs, fiber terminal boxes, and distribution boxes.
