ET5402-SR transceiver is designed to transmit and receive optical data over 50/125 um or 62.5/125 um multimode optical fiber. ET5402-SR is compliant to SFI electrical specifications. The transmitter input and reciever output impedances is 100 Ohms differential. Data lines are internally AC coupled. The module provides dfferential termination and reduce differential to common mode coversion for quality signal termination and low EMI. The transmitter converts 10Gbit/s serial PECL or CML electrical data into serial optical data compliant with the 10GBASE-SR standard.
