Pigtail SC/UPC 06 colors OM3 0.9mm OFNR 3M, semitight

Semi-Tight Buffer Explained

Semi-tight buffering leaves a tiny gap between the buffer and the coated fiber, with no gel or powder inside. The gap can't be seen at 100x magnification. Its practical value is long strip lengths, with at least 10 cm coming off in one circular cut. Splice prep goes faster, and there's less handling of bare glass.

OM3 Specs

OM3 is laser-optimized 50/125 µm fiber with 2,000 MHz·km of effective modal bandwidth at 850 nm. It runs 10GBASE-SR up to 300 meters, 1000BASE-SX well beyond that, and 40GBASE-SR4 up to 100 meters. It's a dependable middle ground for enterprise networks.

Six Strands, Six Colors

The fibers follow TIA-598: blue, orange, green, brown, slate, and white. They match a 6-strand cable directly. Small enclosures stay uncluttered, with no unused pigtails to store.

SC/UPC Connectors

The SC connector holds a 2.5 mm ceramic ferrule in a keyed square housing. It snaps into place and releases with a straight pull. The UPC polish suits standard multimode data equipment.

Protecting Each Splice

Slide a heat-shrink splice sleeve over the fiber before splicing. After the joint is made, center the sleeve over it and shrink it in the splicer's oven. Standard 40 mm or 60 mm sleeves fit most trays. Seat each sleeve in the tray's holder so the splice never carries tension.

This set suits splicing building-entrance cables, small server-room backbones, and campus links between nearby buildings. Contractors working on many small cable counts appreciate the quick strip and the tidy six-fiber count. The six-strand count also suits small industrial buildings that link a few controllers or cameras back to a central switch.
