    Passive Twinax (Copper) Direct Attach Cables compatible with 80% of Networking Equipment , Minimal Power Consumption


    JUHUA's JH-100G-DAC QSFP28 to 4xSFP28 Breakout DAC cables offer precision external cable assembly solutions. They meet the ever increasing demand for higher channel density with high-level signal integrity in high performance computing, top-of-rack switching, and network storage deployments.


    All of our DAC cables are individually tested, met and exceeded industry standards to ensure high performance, cost-effective, quality assemblies for today’s direct attach equipment connections.

    Our DAC cables extremely low-insertion loss due to the unique skinfoam skin, gas-injected dielectric technology as well as extreme control of balanced/unbalanced (Mode conversion). The technology offers ease of cable management and smaller packaging densities. The cable assemblies employ new, innovative PCB technology designed specifically to deliver signal integrity performance. The cables regulate cross talk and launch conditions between wire and PCB termination to optimize return loss and prevent or minimize “ringing” effects.


    JH-100G-DAC is a passive copper direct attach cable (DAC) with quad SFP+ connectors on one end and a single QSFP+ connector on the other end. The fanout cable has 1m length on each segment. The assembly provides short distance (same shelf) inexpensive connectivity at up to 40G data rates and can be used to interconnect 40G and 10G ports. It operates 4 independent 10G channels using the QSFP connector  footprint on one end and 4 independent SFP+ transceivers of 10Gbps each. Each of the four channels can operate at multi-rate speeds Gigabit to 10G (1 Gbps to 10.3125Gbps). Cable has been tested and found compatible with most major brand networking vendors (including Cisco, Juniper, HP and Edge-Core TOR switches).
