This 12-fiber OM4 pigtail set terminates a full 12-strand multimode cable with compact LC/UPC connectors. Twelve fibers make six duplex pairs, which fits LC duplex adapter panels and high-density fiber cassettes. Each 3-meter fiber has a 0.9 mm tight buffer for firm protection in crowded trays.
The OM4 laser-optimized glass supports 10G to 400 meters and 25G to 100 meters. All twelve strands follow the TIA-598 sequence, and the buffer is OFNR riser-rated. It's a natural fit for data center rows and campus backbones built around LC panels. It's a smart match for data centers moving from 10G to 25G multimode links.
High-Density Panels
LC duplex adapters fit 24 or even 48 fibers into one rack unit, compared with 12 or 24 for SC. This set terminates a 12-strand cable into six duplex ports. That leaves room in the same panel for more cables as the network grows.
OM4 Bandwidth Details
OM4 offers 4,700 MHz·km of effective modal bandwidth at 850 nm. It supports 10GBASE-SR to 400 meters and 40GBASE-SR4 to 150 meters. 100G SWDM4 optics reach about 100 meters over a duplex pair. That covers nearly every link inside a data hall.
Polarity Planning
Twelve fibers form six pairs in TIA-598 order: blue and orange, green and brown, slate and white, red and black, yellow and violet, rose and aqua. Keep the same A-to-B pairing at both ends of the backbone. Transmit then reaches receive across every link.
Tight Buffer Protection
A tight 900 µm buffer bonds to each fiber, adding stiffness and crush resistance. That suits LC cassettes and panels where twelve strands share a small tray. Strip it in short passes to protect the glass.
Labeling the Panel
ANSI/TIA-606 sets a common scheme for labeling panels, ports, and cables. Mark each LC port with the panel ID, the port number, and the far-end location. Clear labels save hours when someone needs to trace a link years later.
• Connector: LC/UPC, 1.25 mm ceramic ferrule
• Fiber: OM4 50/125 µm, 850 nm laser-optimized
• Fiber count: 12, TIA-598 color coded
• Buffer: 0.9 mm tight buffer
• Fire rating: OFNR
• Length: 3 m
Clean Every LC End Face
LC ferrules are small, so even tiny particles block a large share of the core. Inspect each connector with a scope and clean it with a one-click LC cleaner before mating. Dirty connectors cause more multimode link failures than any other problem.
Typical Projects
These pigtails suit data center main distribution areas, top-of-rack fiber panels, and enterprise backbones moving from 10G to 25G.
