Network Cable BlueOptics FN-CABLE-QSFP28-2 QSFP28 100G 2m Blue

The BlueOptics FN-CABLE-QSFP28-2 QSFP28 100G 2m Blue is a direct attach copper (DAC) cable engineered for short-reach 100 Gigabit Ethernet connections. Designed for use with QSFP28 ports, this 2‑meter cable provides a fixed, low-latency electrical link between switches, routers or network interface cards in rack-to-rack and intra-rack deployments. Its blue jacket and robust construction simplify cable management while supporting high-throughput environments common in data centers and enterprise networks.

Advantages

This QSFP28 100G cable offers predictable, low-latency performance suitable for high-bandwidth applications. As a copper DAC it does not require separate transceivers, reducing power consumption and lowering total cost of ownership for short-distance interconnects. The 2 m length balances reach and density for typical rack layouts, and the standardized QSFP28 connector ensures compatibility with compliant networking equipment. The cable jacket and connectors are built for repeated insertions and organized cabling in dense installations.

Suitable for

• Rack-to-rack 100G connections inside data centers
• High-speed links between switches and routers with QSFP28 ports
• Interconnects for network interface cards (NICs) and servers
• Short-reach aggregation and leaf-spine network segments

Key specifications

• Interface: QSFP28 to QSFP28
• Data rate: 100 Gbit/s
• Length: 2 meters
• Cable type: Direct Attach Copper (DAC)
• Color: Blue jacket for easy identification
• Typical use: Short-reach, high-density interconnects

How to use

Insert each QSFP28 connector into the corresponding port on your networking devices until it seats securely and any retention latch engages. Ensure both ends are compatible with QSFP28 ports and that linked devices are powered down or configured for hot-plug operations according to vendor guidelines before making connections. Verify link status via device management interfaces after installation and route cable runs to avoid sharp bends and compression that could damage the cable jacket or connectors.

Usage recommendations

Use this 2 m QSFP28 DAC cable for short-distance, high-throughput links where transceiver-based optics are unnecessary. Maintain bend radius and avoid undue mechanical stress; store and route cables in organized trays or cable management panels to preserve signal integrity and ease maintenance.
