Q: What are the main applications of this transceiver?
A: This transceiver is suitable to be used in various applications, such as InfiniBand, data centers, high-performance computing networks, enterprise core and distribution layer applications
Q: What is the main difference between active and passive DACs?
A: Hello! Active DACs have an additional driver chip, passive DACs have not. therefore, active DACs can transmit longer distances.
Q: Why should I trust your compatible transceivers?
A: Besides the price advantage we have compared to branded transceivers, Mvslink's compatible transceivers also maintain the same performance and reliability. To satisfy our customers' high-performance needs, all of our transceivers are tested multiple times in mainstream original-brand switches in our test center before shipping out.
