The APT-RACK-16 rack mount is compatible with heat insert and pull out ,optional single power module and dual power module. Two power module should be power supply at the same time with adopt dual power module.which can reduce the load of each power module.When one channel has fault, the other one can supply the power independently to make the media converter's working can't be interrupted. To maintenance and replacement the power module,you shouldn't pull out the fiber optic media converter and shouldn't take down the rack mount,only need to pull out the blooey power module to repair or updating,make the maintenance convenience and shortcut.afford high dependability for network system. High efficiency, easy operation, easy maintenance and economic ,applied to optical fiber hub resolve project.
