SKU:MMA1B00-C100D
The Mellanox MMA1B00-C100D is a 4-channel, hot-pluggable QSFP28 optical transceiver designed for high-performance 100Gb/s Ethernet connectivity. Using 100GBase-SR4 technology, it supports data transmission over parallel multi-mode fiber with a nominal 850 nm wavelength. The module is SFF-8665 compliant and uses integrated Mellanox technology to deliver reliable operation with efficient power consumption. It is suitable for connecting servers, switches, and other network components in data center and enterprise environments.
The electrical interface features a standard QSFP28 connector supporting CAUI-4, while the optical interface provides four transmit and four receive channels through a standard MPO connector. Each channel supports signaling rates up to 25.78125 GBd, enabling aggregate bandwidth up to 100Gb/s across compatible multi-mode fiber cabling. Its parallel optical architecture provides a flexible solution for short-range, high-speed network links where dependable performance and simplified installation are important.
The MMA1B00-C100D includes digital diagnostic monitoring (DDM) functions for tracking operating conditions and optical performance. Monitoring capabilities include module temperature, supply voltage, laser bias current, transmitted optical power, and received optical power, with warning and alarm thresholds available for key parameters. These diagnostics help network administrators identify potential issues and maintain consistent link performance. Rigorous production testing supports dependable out-of-the-box installation, long-term durability, and reliable operation in demanding networking applications.
