High-Speed Cables
For in-rack and end-of-row cabling, direct attach copper (DAC) and active optical cable (AOC) assemblies remove the need for separate transceivers and patch cords — lowering BOM cost, simplifying inventory, and trimming insertion loss. Optiunik supplies passive DAC twinax cables (10G SFP+, 25G SFP28, 40G QSFP+, 100G QSFP28, 400G QSFP-DD) in 0.5–3 m standard lengths and custom lengths to 7 m; active DAC and AOC variants extend reach to 30 m / 100 m respectively. Connector ends and breakout configurations (e.g., 100G QSFP28-to-4× 25G SFP28, 400G QSFP-DD-to-4× 100G QSFP28, 800G OSFP-to-2× 400G) are fully supported. Every cable is electrically pre-tested for BER, eye-pattern compliance, and Tx/Rx power across the full link budget, and programmed with the customer's switch vendor coding. Bulk pull-test and bend-radius certification ship with each shipment on request.
