The modular principle of the system allows any combination of modules, making the MRU suitable for both splice and patch applications. Three separately extendable bays per height unit can be equipped with 4×4.5" plug-in modules and enable convenient handling during installation and retrofitting. Each slot already has an integrated patch cable routing, which eliminates the need for a separate height unit for cable management and facilitates cable routing. In addition to classic splice and patch modules, the MRU also has breakoutmodules from MTP to LC. Due to the modular design, mixed assembly is also possible.

Cable installation and retrofitting are uncomplicated due to the well thought-out design: The rear cable interception allows fixation and strain relief of incoming cables both laterally and from the back. Six U-recesses are suitable for accommodating up to three M20 or M25 as well as up to six M12 screw connections. The grid on the bottom allows uncomplicated and tool-free fixation and also serves as a cable storage for extra lengths. The patch cables on the front are easy to handle despite the high packing density and are located behind a front flap after installation, which enables clear documentation through labeling options.
