BlueLAN© SC252501KXM30 Direct Attach Cable (DAC) as passive 40 Gigabit Twinax copper type with QSFP to QSFP connector, for linking hardware in racks and across adjacent racks. BlueLAN SC252501KXM30 QSFP Direct Attach Cables are suitable for 10G/40G Ethernet, FCoE, 10G/40G Fibre Channel and InfiniBand (4X SDR, DDR, QDR) applications and are available in various lengths and AWG.

Cost-effective Solution

Benefit from a cost-effective and environmental friendly solution. Direct Attach Twinax Copper Cables are the most common connectivity solution for professional use with short transmission distances in data centers for fast and flexible installations. The main advantages are the low power consumption of 0.1 watt, the low latency, as well as the favorable price.

Cost-effective Solution

High Bandwidth, Low Failure Rate

High Bandwidth, Low Failure Rate

Passive BlueLAN SC252501KXM30 QSFP DAC Direct Attach Cables do not use any active components for 40G data transmissions. This is taken over by the used hardware, which must support passive QSFP DAC Cables. Due to the simple design, passive DAC Twinax Copper Cables have a very low failure rate and low production costs.

Highest Availability

Less maintenance due to a long lifetime. BlueLAN SC252501KXM30 QSFP DAC Twinax Cables only use components of leading manufacturers for Cables (i.a. Amphenol, Belden, Molex, TE Connectivity) and Integrated Circuits (i.a. Maxim Integrated, Netlogic, Mindspeed, Analog Devices). BlueLAN SC252501KXM30 QSFP Direct Attach Cables (DAC) are designed for an above-average operating time of approximately 5.000.000 MTBF hours.

Highest availability

5 year warranty for BlueLAN Direct Attach Copper Twinax Cables DAC
Each BlueLAN SC252501KXM30 QSFP DAC Twinax Cable is covered by a 5-year function warranty by CBO.

Lifetime Support
For the lifetime of the product you receive technical support via email and telephone.
