10Gtek 400G QSFP112 DGX SPARK Compatible DAC 0.5m Passive 30AWG CAB-Q112_Q112-P0.5M

10Gtek 400G QSFP112 Passive DAC Cable - 0.5m

This is a passive Direct Attach Copper assembly from 10Gtek, built for 400G links between closely spaced devices. Its half-metre length and 30AWG conductors make it a tidy, low-latency choice for in-rack connectivity, with no separate transceivers or active electronics required.

Purpose

The cable targets high-traffic settings such as data centres, storage arrays and high performance computing clusters. It suits short runs between servers, storage appliances, switches, routers and any networking gear carrying a compatible QSFP112 port - including DGX SPARK compatible environments that call for a dedicated DAC connection.

Capabilities

Both ends terminate in QSFP112 connectors and deliver an aggregate throughput of up to 400Gbps. The parallel copper construction carries four independent transmit lanes and four independent receive lanes, allowing the full bandwidth to be used. Because the assembly is passive, there is nothing to power inside it, giving a simple, cost-effective and stable short-distance link.

Connectivity & compatibility

It conforms to the IEEE802.3ck and CMIS MSA standards and supports the CMIS management interface together with I2C for EEPROM communication. Careful attention to EMI and EMC behaviour keeps the signal clean across the fast link. Checking compatibility against your specific hardware is recommended before installation.
