optical space division multiplexing (OSDM)
Optical Space Division Multiplexing (OSDM) is a parallel connection of multiple optical fibers, which can be implemented by loose tubes or by multicore fibers such as Multicore Glass Optical Fiber( MC-GOF).
In optical space division multiplexing, each channel is assigned to its own optical fiber and has different bit rates and modulation techniques. During installation, unused optical fibers, so-called dark fibers, must be planned for, which can be switched for further applications or in the event of a fault as a replacement path.
For this reason, multi-fiber cables such as ribbon fiber are suitable for optical space division multiplexing, and bundled optical fibers with more than 5,000 individual fibers are suitable for large applications.
