DAC (direct attach copper) cable systems for SFP+ interfaces
SFP+ (Small Form-Factor Pluggable Plus) or "10GBASE-CR" cable assemblies are an I/O interface system designed to minimise size and to reduce energy consumption in data centres, high-performance computing environments and the entire network storage market.
Copper-based SFP+ solutions from LEONI are a low-cost, low-power, low-latency and hot-pluggable alternative to fiber optic modules. The SFP+ DAC copper cables for 10 Gb/s Ethernet and 8.5 Gb/s Fiber Channel applications are available in transmission lengths of up to 7 m (23 ft) as passive solutions and in lengths of up to 15 m (49 ft) as active versions.
With a tensile strength of 250 N and and its exceptional NEXT characteristics, the LEONI SFP+ copper solutions have set new standards in the industry. Optimised in several respects, the connections consist of a SFP+ connector plug and a twinaxial 100 ohm ParaLink cable. While the design of the circuit boards focused on significantly reducing the near-end crosstalk of signal pairs, the plug housing demonstrates excellent EMC-shielding characteristics. Other unique features include, beside the extremely reliable strain relief with inner and outer crimp rings, an easy release mechanism, which has been enabled through an innovative spring mechanism.
