Features

800GE BASE-R PCS Core Features

  • PCS layer formed by bonded 2x 400GE PCS in PCS Layer
  • Using only 8 virtual logical lanes based on 2 x 16 logical lanes of 400GE PCS to reduce power in 800G operation
  • Well designed into using 112G/s Serdes to provide highest port density for 800G Ethernet solution.
