The 407-BBVN-FL transceiver modules are designed for use in 100G Ethernet links over duplex multimode fiber. Four channels/lanes in the 850, 880, 910, 940nm region @ 25.78Gbps to transport the Ethernet signal. Digital diagnostics functions are available via an I2C interface, as specified by the QSFP28 MSA. The 407-BBVN-FL is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP28 Multi-Source Agreement (MSA). It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference.
The operation in excess of any absolute maximum ratings might cause permanent damage to this module.
