This six-fiber OM4 pigtail set combines compact LC/UPC connectors with an easy-strip semi-tight 0.9 mm buffer. It's built for fast splicing in LC cassettes, wall-mount boxes, and small rack panels. Each 3-meter fiber carries laser-optimized OM4 glass that supports 10G up to 400 meters and 25G up to 100 meters.
The six strands follow the TIA-598 order from blue to white, forming three duplex pairs. The buffer is OFNR riser-rated for indoor and vertical runs. It suits small multimode backbones that connect straight into SFP-based switches. It's a strong option for short OM4 backbones that need quick turnaround.
Quick Prep With Semi-Tight Buffer
The semi-tight buffer sits around the coated fiber with a gap too small to see at 100x. There's no gel or powder inside. One circular cut strips at least 10 cm, so you get a long, clean section ready for coating removal and cleaving.
LC for Modern Switches
The LC connector's 1.25 mm ferrule matches the ports on SFP, SFP+, and SFP28 transceivers. Terminating on LC lets you patch straight to switches with LC duplex cords. There's no need for hybrid SC-to-LC jumpers.
OM4 Reach
OM4 supports 10GBASE-SR at 400 meters and 25GBASE-SR at 100 meters under IEEE 802.3. BiDi optics can also carry 40G up to about 150 meters over a single OM4 pair. That gives you a clear upgrade path without new cabling.
Three Clean Duplex Pairs
Six fibers make three pairs: blue and orange, green and brown, and slate and white. Following this pairing at both ends keeps polarity consistent and makes troubleshooting simpler.
Loss Budget Example
A 300-meter OM4 run at 3.5 dB/km adds about 1.05 dB. Two connector pairs at roughly 0.5 dB each and two splices at 0.1 dB each bring the total near 2.25 dB. That fits under the 2.9 dB that IEEE allows for 10GBASE-SR on OM4.

Fusion Splicing Tips
Use the splicer's multimode program for 50 µm fiber. Clean each stripped fiber with 99% isopropyl alcohol, cleave it flat, and splice. Protect each joint with a heat-shrink sleeve.
Best Uses
This set suits wiring closets, small server rooms, and short building backbones. It's especially handy where speed of installation matters as much as performance.
