In today's era of data explosion, high-speed and stable data transmission has become a demand of various industries. As an important component of 100G network, the core component 100G QSFP28 dual-fiber optical module has attracted much attention. Today, we will deeply analyze the four mainstream models of 100G QSFP28 dual-fiber optical modules: QSFP28-100G-SR4, QSFP28-100G-LR4, QSFP28-100G-ER...
