40G QSFP+ to 4x10G SFP+ passive DAC for short-range data center interconnects.
Connecting high-speed 40G switches to multiple 10G servers often requires complex and expensive optical transceivers. The QSFP+-4xSFP+-DAC-3m simplifies this by providing a direct, passive copper link that splits one 40G QSFP+ connection into four independent 10G SFP+ channels, eliminating the need for active components.
With a fixed length of 3 meters and support for 40Gbps aggregate bandwidth, this cable ensures reliable data transfer with a bit error rate of less than 1E-12. The all-metal housing offers superior EMI performance, while the low power consumption of +3.3V single supply reduces operational costs in dense rack environments.
Ideal for 10 Gigabit/40 Gigabit Ethernet, storage area networks, and fiber channel applications within data centers. This RoHS-compliant solution offers a cost-effective alternative to optical cabling for short-range inter-rack connectivity, ensuring stability and high performance for critical infrastructure.
Connects one 40G QSFP+ port to four 10G SFP+ ports for flexible network topology.
Passive design operates on a single +3.3V supply, reducing energy costs.
All-metal housing provides superior EMI performance and robust protection.
Ideal for short-range data center rack interconnects, replacing expensive optics.
High-quality optical modules and cables for optimal compatibility with your network adapter.
