It can be compatible with HDR/EDR cables, but you need to be aware that using HDR/EDR cables will reduce the connection speed because the maximum bandwidth of HDR/EDR cables are 200 Gb/s and 100 Gb/s respectively. Therefore, if you want to fully utilize the performance of CX7 NDR 200 QSFP112, it is recommended that you use NDR cables, which can provide 400 Gb/s of bandwidth.
