The challenges of migrating optical networks to 400G

While 400G is the answer to increasing data demands, there will be an initial struggle on the network backbone in supporting these initiatives and fulfilling the promise of higher-capacity transport. 400G is not a natural extension to existing network infrastructure, and requires taking into account new restrictions and a redesign of the optical network infrastructure. 400G capacity over a single wavelength with its high baud rate is simply too spectrally wide to pass through the 50-GHz filters and fixed grid ROADMs (reconfigurable optical add-drop multiplexers). A new “runway” is required to reap the benefits of this new technology.

Quiet Light for Future Data Centers

Bringing the speed, high data capacity and low-energy use of light (optics) to advanced internet infrastructure architecture, the FRESCO team aims to solve the data center bottleneck by shortening the distance between optics and electronics through co-integration, while also drastically increasing the efficiency of transmitting extremely high data rates over few fibers using the extreme stability of “quiet light” used at the transmitting and receiving end of the interconnect.

Multifiber Mania: Understanding MPO Connections

MPO connectors are the most likely solution to migrate to 100, 200 and 400 Gb/s. If managers and contractors don’t use MPO or MTP® options and instead stick with LC connectivity, they’re going to end up limiting themselves to either long-reach transceiver applications for single mode, or some type of wave division multiplexing (WDM) technology. Getting started on using MPOs now will set organizations up for success, as higher speeds from 25 Gb/s to 400 Gb/s become the new norm.


A high speed direct attach cable (DAC) is a factory-terminated cable assembly used in data centers for point-to-point connections of active network equipment. These cable assemblies consist of fixed lengths of shielded copper coaxial or fiber optic cable with pluggable transceivers factory terminated on either end. DACs are available in popular transceiver form factors, including SFP, SFP+ and QSFP. High speed interconnect cables are found in data centers, storage area networks and high performance computing centers (HPC) due to the requirement for high bandwidth, connection density and low latency. Four advantages to using DACs are lower price, lower power consumption, plug & play simplicity, and factory terminated performance.

Leading from the Edge: How Edge computing is revolutionizing micro data construction – DCD

Latency times associated with existing infrastructure is approximately 100 milliseconds. Some services, such as online HD video streaming, need latency reduced by up  to three-times to be properly functional. This issue can be mitigated by locating the physical infrastructure closer to the source data and in turn providing higher bandwidth: Edge computing.

Four Ways to Beat Data Center Heat

Data center operators and facility managers continuously work to ensure temperatures remain consistent without raising energy bills. With so many options on the market, it can be hard to decide which one is the best. Beating data center heat is possible, though, and here are four ways to do it: Employ regularly scheduled maintenance, optimize server racks for cooling efficiency, rethink your data center architecture, and increase data center temperatures.
