Irixi's 50G PAM4 QSFP28 ER optical transceiver is well designed for 50G Ethernet interconnection, providing an aggregated signaling rate of 53.125 Gbps and links up to 40KM transmission distance over single-mode fiber (SMF). The module multiplexes 2 channels of 26.5625Gbps NRZ electrical inputs into single 53.125 Gbps PAM4 electrical signal then in turn to convert the electrical signal to 53.125Gbps PAM4 optical signal by a linear laser driver and 25G 1310nm EML laser. Oppositely, the receiver side where the module converts a 53.125Gbps optical signal input into 53.125 Gbps PAM4 electrical signal by APD and linear Trans-Impedance Amplifier (TIA). Then the module de-multiplexes the 53.125 Gbps PAM4 electrical signal into 2 channels of 26.5625Gbps NRZ electrical signal outputs. The module features a hot-pluggable electrical interface, a duplex LC connector, 1310nm center wavelength and is designed to meet the QSFP28 Multi-Source Agreement (MSA) form factor, IEEE 802.3cn 50GBASE-ER, 50GAUI-2 C2M, as well as the RoHS-6 Directive 2011/65/EU6, which is an ideal choice for the 5G optical middlehaul links and backhaul links transmission connectivity.
