303-142-100A Dell EMC 10Gb Dual Port Optical I/O Module

The 303-142-100A is an internal data connectivity interface module engineered to deliver cost-effective network transformation and enhanced system stability within multi-node storage frameworks. Functioning as a high-speed input/output (I/O) expansion card, this dual-port optical interface utilizing an alternate Broadcom architecture delivers 10Gb/s bandwidth per port over SFP+ transceiver links to maintain rapid data synchronization streams and low interface latency. Designed specifically for enterprise storage arrays, it expands operational network pipelines across high-density storage pools, system migration environments, and secondary fiber networks. Its fault-isolated layout manages internal bus communication cleanly, shielding core operational paths from signaling latency, packet drops, or single-point-of-failure throughput disruptions during continuous high-availability runtime operations.
