Applications
In 400G Ethernet data center and cloud network environments, the 400G QSFP-DD QDD ACxxx Active DAC Cable provides a factory terminated 425Gbps link between QSFP-DD ports. This unit is supplied at 1m (3ft). Because the assembly is factory terminated and tested as a complete link, installation is plug and play on both ends. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment.
Standards and Compatibility
This product is designed and tested to comply with QSFP-DD MSA, SFF-8636. It plugs into any standards-based QSFP-DD port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
Ordering Information
