The Edge-Core 10G SFP+ ET5402-LR transceiver is designed to transmit and receive optical data over single mode optical fiber for link length 10km. The ET5402-LR is compliant to SFI electrical specifications. The transmitter input and receiver output impedance is 100 Ohms differential. Data lines are internally AC coupled. The module provides differential termination and reduce differential to common mode conversion for quality signal termination and low EMI.
