PRODUCT DESCRIPTION
They are compliant with SFF-8431,SFF-8432. The transmitter converts serial CML electrical data into serial optical data compliant with the IEEE802.3by standard. The receiver converts serial optical data into serial CML electrical data.Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-8472.
An optical fiber ribbon cable with an MTP/MPO connector can be plugged into the QSFP28 module receptacle. Digital diagnostics functions are available via an I2C interface, as specified by the QSFP+ M
The laser based 100Gigabit Transceiver is designed to transmit and receive serial optical data over multimode optical fiber with 100m.
