The Ethernet standard relied on duplex fiber cabling with each channel using one fiber to transmit and the other to receive. But for the 802.3ab standard, parallel optics are required to transmit and receive signals. For instance, there are eight fibers...
With the speed in the data center now increases from 10G to 40G, different optical technology and cabling are required. But at first we should figure out the design of 40G Ethernet network. There are several key factors that may affect the transition...
Data center regularly went through great migration from 1G, 10G to 40G, 100G over the past few decade. Since IEEE 802.3ba standard defined the 40G Ethernet on June 17, 2010. The newest widely adopted optical transceivers is the QSFP+ that offers aggregated...
