BlueOptics MikroTik Q+BC0002-S+ Compatible BlueLAN QSFP+ DAC Twinax Cable, 2m, 40G, Passive Copper

In high-density data centers and enterprise server rooms, network engineers often need a reliable, low-latency link between top-of-rack switches and storage nodes. The BlueOptics BlueLAN QSFP+ direct attach cable delivers exactly that: a 2-meter passive twinax copper connection that handles 40 Gigabit Ethernet without the cost or power draw of optical transceivers. It is fully compatible with MikroTik Q+BC0002-S+ ports and any MSA-compliant QSFP+ interface, making it a drop-in solution for short-reach interconnects.

Key specifications

• Form factor: QSFP+ to QSFP+ (Quad Small Form-factor Pluggable Plus)
• Data rate: 40 Gbps (40GBASE-CR4 Ethernet, InfiniBand QDR/FDR)
• Cable length: 2 meters
• Cable type: Passive twinax copper, 30 AWG, 100 Ohm impedance
• Power consumption: less than 0.5 W (passive, no external power needed)
• Operating temperature: 0°C to 70°C; storage: -40°C to 85°C
• Voltage supply: 3.3 V; hot-pluggable: yes
• Jacket material: PVC; certifications: CE, FCC, RoHS

Why choose it

Passive DACs are the smart choice for links up to a few meters: they cost a fraction of optical transceivers, consume almost no power, and introduce near-zero latency. This cable is built to MSA standards and tested for MikroTik compatibility, so you can trust it in mixed-vendor environments. The 30 AWG wire keeps the cable flexible and easy to route in tight racks, while the robust PVC jacket withstands daily handling.

Ideal use cases

• Connecting MikroTik Q+BC0002-S+ switches to servers or storage arrays within the same rack
• Short-reach 40G Ethernet links in data centers, enterprise server rooms, and high-performance computing clusters
• Replacing optical transceivers for cost savings and lower power consumption in short-distance interconnects

Good to know

This passive copper cable requires no external power and is hot-pluggable for easy installation. It is compliant with CE, FCC, and RoHS regulations, ensuring safety and environmental standards. The cable is designed for indoor use and should be handled with care to avoid excessive bending.
