Micro Connectors' Bulk CAT6 Shielded Cable provide you with 250 feet of high quality, shielded, 4-pair, solid, 550 MHz Cat6 Cable, ready for termination and routing. The Mylar foil shielding protects your data as it travels through the four twisted pairs of 23 gauge solid copper wires by wrapping it in a thin metal sleeve thus keeping electrical interference from things like fluorescent lights and electrical lines found in a drop ceiling or inside walls at a minimum. And like all of our bulk networking cables, these are constructed with only high-quality components that can be counted on for high performance.
