Black Box C6AJA70-BL-R2 Cat 6A RJ-45 Coupler, 500 MHz

When a copper run needs to be extended cleanly, this Cat 6A RJ-45 coupler keeps the link simple. The Black Box C6AJA70-BL-R2 is built for 10 GbE and PoE applications and supports data rates up to 500 MHz, making it a practical fit for enterprise cabling where performance and consistency matter. Use it to join two pre-terminated Ethernet cables without re-pulling cable or changing the termination strategy. In access closets, work areas, and equipment rooms, a passive in-line coupler can save time while preserving the integrity of the channel. The blue housing also makes it easy to identify in dense patching environments. For infrastructure teams, the value is in keeping the network path clean and predictable. This coupler supports the kind of disciplined cabling practices that reduce troubleshooting time and protect the performance of higher-speed copper links.
