DAC Cable
JTOPTICS Direct Attach Cable (DAC) assemblies are high speed, cost-effective alternative to fiber optic transceiver and cables in 10G, 40Gb, 100G and 400G applications. Ideal for highly cost-effective networking connectivity within a rack and between adjacent racks. They enable hardware OEMs and data center operators to achieve high port density and configuration at a low cost. Our DAC twinax copper cables are available with brand compatible version and compatible with major brands like Cisco, Finisar, Juniper, Arista, Dell, HPE, Extreme, Brocade, Mellanox, H3C, Intel, IBM, Nokia, Ciena, Huawei, Ixia.
Seamless High-Speed Connections: DAC Cables for Data Center & Telecom Efficiency
JTOPTICS® Direct Attach Copper (DAC) cables are cost-effective, high-performance solutions designed for short-distance, high-speed data transmission in data center and telecom environments. These twinaxial cables feature integrated transceivers at both ends, making them ideal for rack-to-rack or within-rack connections at speeds like 10G, 25G, 40G, 100G, and beyond.
Known for low latency and low power consumption, DAC cables simplify deployment, reduce network complexity, and ensure reliable performance—making them the go-to choice for top-of-rack (ToR) and middle-of-row (MoR) architectures in high-density networking setups.
