The Patton Model 570 twisted pair surge protectors are EIA/TIA TSB-40A certified, and operate at speeds up to 100 Mhz. And with specs like N.E.X.T. of -43 db (worst pair), you can rest assured that these units will protect your 10/100/1000Base-T, RS-422 or 100VG-AnyLan data lines without hindering critical network performance. The Model 570 is designed for use at the sensitive equipment port, while the Model 580 protects barriers (wiring closets, patch panels, etc.).
