FB-MC40G-3R  provides media conversion and distance extension and signal regeneration for 40G or 10G Ethernet links.


Fiberbit FB-MC40G-3R provides media conversion and distance extension for 40G or 10G Ethernet links. It is hot-swappable with two QSFP sockets for QSFP transceivers. Installation and setup is simple plug and play. Insert the module into any powered Fiber Driver chassis with the QSFP transceivers required for the application, and then connect to the network. Applications include:

  • Media conversion and distance extension for 40G or 10G Ethernet links.

  • Media conversion (multi-mode to single-mode) and link range extension. (The multi-mode QSFP may be used with MPO MM (40G) or with fan-out cables for quad 10G interfaces.)

Modern networks rarely rely on pure topologies like bus, ring, or star. Most common solutions use hybrid topologies, which are combinations of features from those three.   Star-Wired Ring As it is clear from the name, star-wired ring topology has features of star and ring topologies. You can see example of this topology ...
