The HDM Cassette 3x MPO-12 to 36x LC/APC is a high-density fiber breakout module designed for use within HDM rackmount panel systems. Designed to integrate seamlessly into HDM modular rackmount panels, this cassette enables rapid deployment and clean migration from parallel MPO architectures to duplex LC/APC connectivity. As part of the broader HDM cassette and adapter plate ecosystem, it is fully interchangeable with other HDM connectivity modules, supporting flexible network designs and future scalability. The breakout cassette has rear MPO access broken out to LC/APC in the front. The metal cassette enclosure provides superior impact resistance and long-term reliability compared to traditional plastic designs, making it well suited for data center, service provider, and enterprise environments.The HDM Cassette 3x MPO-12 to 36x LC/APC is a high-density fiber breakout module designed for use within HDM rackmount panel systems.
