Network Cable BlueOptics QSFP-40G-D-AOC-1M QSFP 40GBASE-SR4 1 Meter Blue

The BlueOptics QSFP-40G-D-AOC-1M is an active optical cable engineered for high-speed short-reach connectivity. Compliant with 40GBASE-SR4, this 1 meter QSFP cable provides four-channel multimode optical transmission designed for Ethernet and InfiniBand FDR10 links. Its compact QSFP form factor and blue jacket make it suitable for dense data center topologies where reliable, low-latency links and straightforward cable identification are required.

Advantages

The cable integrates active optics to deliver stable 40 Gbit/s aggregate throughput over multimode fiber without separate transceivers, reducing port density and power consumption compared with discrete module plus fiber assemblies. The 1 m length minimizes signal loss and latency in short-reach interconnects and simplifies patching within racks and across adjacent switches. The blue outer jacket enhances visual management in populated cabling environments.

Suitable for

• 40 Gigabit Ethernet switch-to-switch or switch-to-server connections
• InfiniBand FDR10 links in HPC clusters
• Top-of-rack (ToR) and adjacent-rack short-reach interconnects
• High-density data center patching and cable management

Key specifications

• Form factor: QSFP (Quad Small Form-Factor Pluggable)
• Data rate: 40 Gbit/s aggregate (4 lanes)
• Standard: 40GBASE-SR4 multimode optical link
• Length: 1 meter
• Active optical cable (AOC) design with integrated transceivers
• Connector: QSFP to QSFP direct connection
• Cable color: blue jacket for easy identification

How to use

Insert the QSFP connector into compatible QSFP ports on network switches, routers, or servers ensuring proper orientation. Use the cable for short-reach connections within racks or between adjacent racks; the 1 m length is intended for direct patching without additional fiber. Verify port settings and link negotiation on network devices after insertion. For hot-pluggable operation, handle the module by its housing and avoid touching optical interfaces to prevent contamination.

Usage recommendations

Use this 1 m AOC in environments where short, high-bandwidth links are required and transceiver-to-fiber assemblies would increase complexity. Keep connectors capped when not in use, route the cable to avoid sharp bends, and maintain multimode fiber cleanliness to preserve signal integrity and link stability.
