The FINISAR 40G QSFP+ breakout cable ensures reliable, energy-efficient data transmission across large-scale data centers, enterprise infrastructures, and cloud environments.

High-Speed Active Optical Design

This FINISAR 40G QSFP+ breakout cable uses active optical technology to convert electrical signals into optical signals, minimizing electromagnetic interference (EMI) and maintaining signal integrity. Compared to traditional copper cables, its active optical design delivers lower latency and higher transmission quality. The 10-meter length provides excellent flexibility for server-to-switch or switch-to-switch interconnections without sacrificing performance.

Build Quality and Durability

Engineered for demanding environments, the FINISAR 40G QSFP+ to 4x SFP+ Active Optical Breakout Cable is constructed with premium materials and thoroughly tested for signal integrity and mechanical stability. Its lightweight yet robust jacket ensures easy cable management in dense rack installations. The secure locking mechanism on both QSFP+ and SFP+ connectors guarantees a stable connection and minimizes data loss during continuous operation.

Compatibility and Standards

The FINISAR 40G QSFP+ breakout cable fully complies with IEEE 802.3ba, QSFP+ MSA, and SFP+ MSA standards. This ensures seamless interoperability across multiple vendors and networking platforms. It is compatible with major switches, routers, and servers that support QSFP+ and SFP+ interfaces, making it a versatile choice for hybrid 10G/40G network environments.

Performance and Efficiency

The FINISAR 40G QSFP+ to 4x SFP+ Active Optical Breakout Cable – 10M provides exceptional signal clarity, ultra-low bit-error rates, and consistent throughput across its full reach. Its low-power operation reduces overall energy consumption while delivering superior data transmission. This makes it ideal for applications requiring high bandwidth, low latency, and efficient power utilization—such as cloud computing, high-performance computing (HPC), and large-scale data analytics.
