T1-QSFP28-100G-FR1 is designed for 2km optical communication applications. The module incorporates one channel optical signal, on 1310nm center wavelength, operating at a 50Gbaud data rate. The transmitter path incorporates an EML Driver and a cooled EML. On the receiver path, the input optical signal is coupled to a Pin photodiode detector. A DSP-based gearbox is used to convert 4x25Gbps NRZ signals to 1x50Gbaud PAM4 signal and a 4-channel retimer and FEC block are integrated into the DSP. The electrical interface is compliant with IEEE 802.3cd and QSFP28 MSA in the transmitting and receiving directions, and the optical interface is compliant with IEEE 802.3cd and 100G Lambda MSA with a Duplex LC connector.
The module has a maximum power consumption of 3.5W. T1-QSFP28-100G-FR1 is designed with form factor, optical/electrical connection, digital diagnostic interface according to the QSFP28 Multi-Source Agreement (MSA), and to meet the harshest external operating conditions including temperature, humidity, and EMI interference.
