10G SFP+ Passive Direct Attach Copper Cable

The utility model relates to a high-speed cable with SFP+ connectors directly integrated at both ends (no independent optical module required), and a copper cable (non-optical fiber) inside, which is suitable for short-distance transmission. Advantages: Low cost, low power consumption, plug and play (no need to configure optical modules and optical fibers)
