The Sun 530-4444-01 is a 3-meter 40GBASE-CR4 passive direct attach copper (DAC) twinax cable designed for high-speed interconnect between 40 Gigabit Ethernet switches, routers, and line cards. This part number supports QSFP+ to QSFP+ connections at 40 Gbps per lane across four lanes, delivering 40 Gbps aggregate throughput over passive copper conductors. The cable's 3-meter length accommodates mid-range rack and cluster deployments without active signal conditioning, reducing power consumption and latency compared to active solutions.
Compatible with Sun/Oracle SPARC and x86 systems, Cisco, Arista, Juniper, and other standards-compliant 40GbE infrastructure. Typical use cases include data center core switching, high-performance computing clusters, and server-to-switch fabric connections where cost-effective, low-latency connectivity is required. The twinax construction provides robust shielding and durability in production environments.
