OSFP 400G SR8 DAC Direct Attach Cable is a twinax cable solution with two copper-based conductors for transmitting electrical signals at short distances. The OSFP DAC Direct Attach Cable transmit the signals faster (i.e. with a lesser latency) and require considerably less current, compared to electrical signals sent via a twisted pair cable. JT-OSFP-400G-DAC Direct Attach Cable (DAC) as passive 400 Gigabit Twinax copper type with OSFP to OSFP connector, for linking hardware in racks and across adjacent racks. JTOPTICS JT-OSFP-400G-DAC OSFP Direct Attach Cables are suitable for 400G Ethernet as well as InfiniBand applications and are available in various lengths.
