Digitus QSFP+ 40G 5 m AOC kábel plný duplex DN-81312

Digitus QSFP+ 40G 5 m AOC cable Full duplex DN-81312 is a 5 metre active optical cable with QSFP+ connectors on both ends, designed for short-range, high-bandwidth links in data centres and network environments. The cable supports aggregated data rates suitable for 40G applications and is compliant with QSFP MSA and IEEE P802.3ba standards.

Advantages

This active DIGITUS® 40G QSFP+ AOC cable provides high performance with low power consumption for short-range connections. It supports multiple protocols including InfiniBand QDR/DDR/SDR, Fibre Channel modes and interfaces such as PCIe and SAS. The design uses four full-duplex channels, each capable of up to 11.3 Gbps, enabling an aggregated throughput near 40G while improving port density and reducing overall system cost.

Suitable for

• High-speed links between switches and routers in data centres
• Server-to-switch connections requiring 40G bandwidth
• Short-reach interconnects in storage and compute clusters
• Environments using QSFP+ ports and compatible vendor equipment

How to use

Insert the QSFP+ connector into compatible QSFP+ ports on both devices, ensuring correct orientation and a secure connection. The active optical cable is plug-and-play with supported hardware; confirm that ports support the desired data rate and protocol. Route the cable to avoid tight bends and mechanical stress, keeping the maximum bend radius recommended by the equipment vendor. No separate power supply is required beyond the host devices.

Recommendations

Use this DIGITUS QSFP+ 40G AOC for short-range 40G interconnects within racks or between adjacent racks. Verify compatibility with your switch or server vendor and test link negotiation at the intended speed before deploying in production.
