Xero-U panel solution is designed to accept a full array of MPO/MTP cassettes and offering a flexible solution to the end user. The design incorporates a multi functional panel, which mounts vertically on to the cable tray within the rear of the equipment cabinet and consumes no rack U-space, making it the perfect solution for tight spaces. It dramatically simplifies cable routing complexity, allows the high-density outlet ports to align with the "U" positions of the uprights within the Cabinet and most importantly provides space to manage active equipment. Because of its modular construction airflow disruption is also minimized. The panels in the basic form are supplied unloaded ready for you to install the adapter of your choice.
