Certified Quality

Our quality policy is maintained throughout our business in accordance with our commitment to customer and regulatory requirements.

400G QSFP-DD to 4x 100G QSFP28 PCC (Passive Copper Cable), also known as Direct Attach Copper (DAC) cable or Twinax cable, provides robust connections between 400G Ethernet and 100G Ethernet systems. Each cable consists of four lanes each operating at data rates of up to 100Gb/s (PAM4). This integrated cable solution provides reliable transport for aggregate data rates of up to 400Gb/s. Optimizing systems to operate with JTOPTICS 400Gb/s passive copper cables significantly reduces power consumption and EMI emission, eliminating the use of Enterprise Data Center (EDC) hosts.
