traffic to increase sharply, more and more financial organizations, OptiXtrans DC908 is built on more than 20 years of optical field
experience and helps customers cope with challenges brought
by massive data transmission in the cloud era. It offers twice
the stability of industry’s average performance. By implementing
port-level encryption at the physical layer and supporting 50 ms
protection switching, it can ensure service continuity. Utilizing
built-in fiber channel (FC) interfaces to maximize the synergy
between storage and optical transmission, the product thereby
reduces the latency of the active-active application in 100 km to
less than 1 ms for intra-city disaster recovery. Moreover, it enables
effortless zero-touch deployment with network-level WebGUI.
Leveraging simplified design to cut the number of optical-layer
fiber connections by more than 90%, the product greatly reduces
footprint and simplifies O&M.
