Black Box 25ft Shielded 26AWG CAT5e 100MHz Ethernet Patch Cable (Black)

Overview

The Black Box EVNSL0172BK-0025 is a 25-foot shielded CAT5e Ethernet patch cable designed to deliver consistent Gigabit Ethernet performance in environments with high electrical interference. It supports data transmission frequencies up to 100 MHz, making it suitable for 10/100/1000 Mbps networks. This cable is ideal for professional settings where reliable network connections are critical despite nearby power lines, fluorescent lighting, or industrial machinery.

Its construction includes four twisted pairs wrapped in Mylar tape with a dedicated drain wire, all enclosed in an aluminum and Mylar shield to block electromagnetic and radio-frequency interference. The cable’s 26 AWG stranded copper conductors ensure stable signal transmission, while the black jacket and slimline molded boots provide practical benefits for installation and maintenance.

Key features

• Full shielding with aluminum Mylar wrap and drain wire effectively blocks EMI and RFI, preserving data integrity in noisy environments
• 25-foot length offers flexible routing options for connecting devices across rooms or through vertical cable management systems
• Certified to CAT5e 100 MHz standard, supporting 10/100/1000 Mbps Ethernet for a wide range of network applications
• 26 AWG stranded copper conductors provide reliable and consistent signal transmission over the cable’s length
