Description
The Black Box Ethernet Extender - 4-Port is a high-performance solution designed to bring Ethernet connectivity to distant locations over existing copper wiring. Built on ITU-T G.991.2 SHDSL.bis symmetric technology, this extender delivers rate-adaptive nx64 speeds up to 15 Mbps, providing dependable, balanced uplink and downlink performance over two-wire copper. Ideal for linking remote offices, manufacturing floors, security camera networks, and industrial environments, this device enables you to extend your LAN without the expense and disruption of running new fiber or coax. With a pair of units communicating over copper cables rated from 19 AWG to 26 AWG, you gain a flexible, scalable network extension that supports modern business demands while preserving your current cabling investments. The 4-Port variant adds considerable versatility by offering multiple Ethernet connections on each NTU, allowing you to consolidate devices, reduce wiring complexity, and streamline deployment in compact spaces. Whether you are modernizing an existing copper network or deploying a new, cost-effective extension, this Ethernet Extender delivers stable, scalable performance with minimal configuration.
- High-speed Ethernet over copper: Leveraging ITU-T G.991.2 SHDSL.bis, the device provides rate-adaptive nx64 speeds up to 15 Mbps symmetric, ensuring balanced performance for file transfers, video streams, and real-time applications across the extended link.
- 4-port Ethernet interface on each unit: Four LAN ports on the NTU deliver flexible connectivity for multiple devices, allowing a small office, workshop, or remote site to share a single SHDSL link without sacrificing individual device performance.
- Flexible copper compatibility: Designed to operate over dry two-wire copper cables across a range of gauges from 19 AWG (0.9 mm) to 26 AWG (0.4 mm), providing install versatility and compatibility with legacy and current cabling environments.
- Easy pair-and-connect deployment: The extender is engineered to work in matched pairs, creating a transparent Ethernet bridge between sites with straightforward wiring and minimal setup, so you can deploy quickly and reliably.
- Rugged, business-class reliability: Built for commercial environments, the Black Box Ethernet Extender emphasizes robust construction and dependable performance to support continuous operations in office, industrial, or campus settings.
