The cable delivers simple plug-and-play connectivity between SFP+ ports and is compliant with EEPROM I2C, MSA, and TTA standards, which makes integration with HPE FlexNetwork H3C equipment and several listed modules straightforward. For anyone who needs a 3 m passive copper option that avoids the complexity and cost of optics, this cable mostly delivers what it promises.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e10 Gbps performance:\u003c\/strong\u003e Provides a full 10GBase-CU link for short-range connections, enabling high-throughput transfers between compatible SFP+ ports.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlug-and-play installation:\u003c\/strong\u003e Passive design requires no external power or configuration, so it installs quickly in server racks and switches.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards compatibility:\u003c\/strong\u003e Compliant with EEPROM I2C, MSA, and TTA for broad interoperability with HPE FlexNetwork and related modules.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable construction:\u003c\/strong\u003e 30AWG twinax copper construction offers a reliable physical connection for frequent insertions and reconfigurations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3 m length:\u003c\/strong\u003e At 3 meters (9.84 ft) the cable is suited to common rack-to-rack and top-of-rack runs without excess slack.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtocol support:\u003c\/strong\u003e Works with 10G Ethernet, Fibre Channel and InfiniBand QDR\/DDR\/SDR protocols for diverse environments.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe cable is aimed at network technicians, system administrators, and small data center operators who need reliable short-range 10 Gbps links without buying optical transceivers and fiber.
