Black Box 25ft CAT6 250MHz Shielded Ethernet Patch Cable (Gray)

Overview

The Black Box EVNSL0272GY-0025 is a 25-foot CAT6 shielded Ethernet patch cable designed to provide stable and high-speed network connections in environments prone to electromagnetic and radio-frequency interference. Rated for 250MHz frequency, it supports Gigabit Ethernet speeds, making it suitable for transmitting voice, data, and audio/video signals with minimal disruption. Its robust shielding and durable connectors ensure consistent performance in both home and professional networking setups.

Key features

• Double shielding with individually shielded twisted pairs and an overall tinned copper braid reduces EMI and RFI interference for cleaner signal transmission
• 50-micron gold-plated contacts enhance conductivity and minimize signal loss, improving overall network reliability
• Connectors rated for up to 750 insertion and extraction cycles provide long-lasting durability even in frequent-use scenarios
• Meets or exceeds CAT6 standards at 250MHz, supporting high-speed Gigabit Ethernet applications such as 1000BASE-T, 100BASE-TX, and 10BASE-T
• Foam insulation around twisted pairs helps maintain signal integrity by reducing crosstalk and external noise
