Cisco 400G BiDi uses fiber efficiently through bidirectional technology and wavelength division multiplexing. Parallel unidirectional technologies require more fiber cabling to achieve the same bandwidth.

Duplex fiber efficiencies with Cisco BiDi innovations enable you to increase capacity across your data center cable infrastructure.

In a cable trunk with 16 pairs of fiber you can achieve 4x more capacity vs. 400G SR4.2

• 1.6 Tbps total bandwidth with 400G SR4.2
• 6.4 bps total bandwidth with 400G BiDi
