Network Cable BlueOptics FN-CABLE-QSFP+2 QSFP DAC 2m Black

The BlueOptics FN-CABLE-QSFP+2 QSFP DAC 2m Black is a direct-attach copper cable engineered for short-reach, high-bandwidth connections. At 2 metres in length, this QSFP+ passive twinax cable provides a low-latency link suitable for switches, routers and servers that support QSFP+ ports. The cable’s compact, molded connectors and black jacket are designed for dense cabling environments and straightforward installation in racks and data center top-of-rack layouts.

Advantages

This QSFP DAC cable delivers reliable, low-power connectivity without the need for additional transceivers, reducing hardware and operational complexity. Its 2 m length balances reach and signal integrity for typical rack-to-rack or within-rack connections. The cable’s construction supports stable performance for high-speed data transfer and minimizes insertion loss in short-distance links.

Suitable for

• High-speed interconnects between switches and servers in data centers
• Top-of-rack and end-of-row network cabling
• Short-reach aggregation and spine-leaf fabrics
• Environments requiring compact, low-latency copper links

Key specifications

• Connector type: QSFP+ direct-attach copper (DAC)
• Length: 2 metres
• Color: black jacket
• Application: short-reach, high-bandwidth interconnects
• Compatibility: QSFP+ port devices supporting DAC cables
• Typical use: within-rack and rack-to-rack connections

How to use

Insert each QSFP+ connector into the corresponding QSFP+ port on your network devices until the latch engages. Ensure both devices support passive QSFP DAC connections and that ports are powered down or follow hot-swap procedures recommended by the device manufacturer. Route the cable to avoid sharp bends and maintain recommended bend radius. After installation, verify link status via device LEDs or management interfaces and confirm negotiated speeds and link integrity.

Usage recommendations

Use this 2 m QSFP DAC for short-distance links where minimizing latency and power consumption is important. Avoid exceeding the recommended bend radius, keep the cable clear of sources of electromagnetic interference, and confirm compatibility with your QSFP+ ports before deployment. For longer runs or optical isolation requirements, consider using active DACs or optical transceivers with fiber cabling.
