These cassettes are a core component of high-density structured cabling systems, particularly in data centers. Their primary function is to act as a breakout module, which is essentially a fan-out device. A high-capacity MTP/MPO trunk cable plugs into the rear of the cassette, and the cassette distributes those individual fibers to multiple standard LC connectors on the front panel. The MPO / MTP® module box is pre-termianted to increase the installation speed. The module box and the external MPO / MTP® port can be easily and efficiently connected to the main line. A single MPO / MTP® provides instant connection to 12 fibers.
