Check current stock for 40Gbps RJ45 adapters.
I’m just seeking information on products related to Cat8 RJ45 cables. I noticed a recent standard for 40Gbps speeds, but haven’t found any available solutions or components like PCIe cards or QSFP+ transceivers. I’m looking for existing products that support this speed rather than discussing its practicality for DIY projects.
Doesn't match any known tech. CAT8 advertises 40 Gbps, but no devices currently deliver that over standard Ethernet. It seems the standard might rely on a different connector like Terra instead of RJ45. Keep in mind the speeds are only valid for short distances, such as server rooms. Even if such gear existed, fiber would likely be more cost-effective. Looking back at early 10 Gbps Ethernet products, buying used enterprise equipment was often cheaper.
I don't think any exist, and I'm not sure if they will ever exist. Fiber is the future.
In reality, Cat8.1 and 8.2 offer options for RJ45 and Terra connectors, but your main idea is accurate—no such product exists on the market, and it’s unlikely to appear anytime soon. Power consumption for 10G copper SFP+ modules is already double that of fiber 10G SFP modules. A 25g copper module would be even more demanding, let alone a 40g one.
