Comprehensive analysis of FTTH for fiber access

Fiber-optic communication(FTTx) has always been regarded as the most promising broadband access method after DSL broadband access. Unlike common twisted pair communication, it has higher operating frequency and larger capacity (can be based on users need to upgrade to exclusive bandwidth of 10-10... Read More

From 100G to 400G, what kind of “core” power is needed for data center communication?

“Network” has become a “necessity” for most contemporary people. The reason why such a convenient network era can come, “fiber-optic communication technology” can be said to be indispensable. In 1966, the British Chinese sorghum proposed the concept of optical ... Read More
