Description
This product uses a 76-pin QSFP-DD MSA QSFP-DD Hardware Specification connector for all electrical interfaces with the host card, whereas the optical interfaces on the line side are provided through the optical receptacles on the QSFP-DD. The module can be portioned into three functional parts: TX path, RX path and Control & Power block.The host interface is comprised of a total of 8 high-speed SerDes lanes. This allows module to support one interfaces for 400G application: an independent double 4-Lane mode client interfaces (for 400GbE application).
