Optical transceiver is a small product, it seems simple. In fact, it is assembly completed after more than 10 processes, but still can’t be sold. Because the product need to be strictly testing before shipment, including parameter testing, aging testing, distance testing (fiber testing) and switch testing. We've had a detailed explanation of the tests except switching testing, today we're going to...

Energy saving and cost are two important factors that need to be considered when deploying data centers. The price of 40G optical module and 100G optical module is too high and the power consumption is too large, and the speed of 10G optical module can not meet the demand of network. Therefore, 25G SFP28 optical module was born in this case, just to make up for the deficiency between the them, gre...
