Engineered for advanced OM4 multimode systems, this MPO optical keystone adapter supports 8, 12, and 24-core MPO connectors in a Key Up/Key Down configuration, providing built-in polarity reversal for precise Tx/Rx mapping. The violet housing ensures quick identification of OM4-grade fiber, helping maintain proper network segmentation. Zirconia ceramic sleeves deliver exceptional alignment accuracy, reducing insertion loss and maintaining stable high-speed transmission for 40G, 100G, and emerging 400G parallel optics links. Designed in a universal keystone format, it fits seamlessly into patch panels and enclosures, making it an essential component for high-density, high-bandwidth network environments that demand superior optical reliability.
