What is the ProCurve Switch vl 1-Port 10-GbE X2 Module (J8766A)?
The J8766A module is a single port 10-GbE transceiver module intended to support the existing X2 transceivers for uplink connectivity. Expected throughput is between 2.5 and 7Gbps depending on packet size. However, traffic from a single source MAC address to a single destination MAC address will be limited to a maximum of 1 Gbps throughput. That makes this module ideal for switch-to-switch connections.
