The Dell 0JCYM9 (also known as JCYM9 or MAM1Q00A-QSA28) is a QSFP28-to-SFP28 adapter—a compact, hot-pluggable transceiver converter that allows a 100 GbE QSFP28 port to accept a 25 GbE SFP28 transceiver. It enables deployment of a single 25 GbE module from a 100 GbQSFP port when QSFP breakout or port partitioning isn't available or desired. Commonly used in data center environments to increase flexibility, this adapter is OEM-certified for Dell systems and works with compatible SFP28 optics. It’s often refurbished and sold without external electronics (purely passive adapter), facilitating reliable conversion with minimal signal loss.
