Honey is a friend!
What you are talking about is an optical storage device, such as Huawei OceanStor S2200T&S2600T&S5500T&S5600T&S5800T&S6800T. Their external input and output are mainly realized through optical fibers, which facilitates long-distance and large-capacity data transmission. Applicable to large-scale data centers.
Non-fiber storage devices are connected through Ethernet cables, and data interaction is affected by distance and bandwidth. Applicable to small data centers.
Thanks!
