SKU CH-B24F-9N25C

Two RJ45 couplers extend Ethernet links up to 328 ft at 10 Gbps with gold-plated contacts and aluminum shells

  • ColorGray
  • Extend network runs up to 328 ft without signal loss
  • 10 Gbps throughput handles large downloads at maximum velocity
  • Gold-plated copper contacts with snap-in clip ensure steady signal transmission
  • Works with Cat8, Cat7, Cat6A, Cat6, Cat5e and Cat5 cables
  • Aluminium alloy shell resists wear and aids heat dissipation

Subynanal Su-3 RJ45 Coupler 2 Pack

The Subynanal Su-3 is a pair of female-to-female RJ45 couplers designed to join two Ethernet cables into a single longer run. Each unit supports data rates up to 10 Gbps and remains downward compatible with 1000 Mbps, 100 Mbps and 10 Mbps networks. The gray aluminum alloy shell provides a compact, durable housing for home or office wiring projects.

Thermals noise and power draw

As a passive connector the coupler draws no power and generates no audible noise during operation. The aluminum alloy shell aids heat dissipation from the gold-plated copper contacts, keeping signal integrity stable across the full 328 ft transmission distance. No external power supply or active cooling is required for normal use.

Sustained load behaviour

Under continuous high-throughput traffic the gold-plated contacts and snap-in retaining clip maintain a secure, low-resistance connection without signal degradation. The passive design means performance does not throttle over time, and the coupler remains compatible with Cat8, Cat7, Cat6A, Cat6, Cat5e and Cat5 cabling throughout extended transfers.

Questions about this item

How do I install the Su-3 coupler and what step do people often miss?

Plug each cable firmly until the retaining clip clicks; the step people miss is not pushing far enough to lock both sides.

What maintenance or replacement will the Su-3 coupler need over time?

No scheduled maintenance; replace only if the gold-plated contacts become corroded or the retaining clip breaks.

What limit appears first when the Su-3 coupler runs at 10Gbps over long distance?

The 328ft maximum transmission distance is the first limit; beyond that signal integrity drops.
