The 400G OSFP56 Passive Direct Attach Copper Twinax Cable is designed for use in 400GBASE Ethernet.,OSFP56 is the module and cage/connector system based on current OSFP, targeting to support the 56Gb/s per lane speed in a 8x lane OSFP system and to enable the OSFP 400G interconnect ecosystem. This will greatly help the legacy OSFP users upgrade the link bandwidth to 400G per port with lower cost and shorter transition time.
