LWLG’s Back Story Redux 1-23
Connectivity is critical
This need for connectivity is shared across industry verticals and across continents. While networks are adapting to enable more advanced infrastructure approaches to sending and receiving data, the fundamental need for access to that data remains. Organizations must transport data to locations both far and near, and they rely on their networks to keep them connected at all times.
DCI: the backbone of the digital world
Modern life relies on data centers. Hidden from most, these physical facilities are the backbone of the internet, storing and computing information for every industry, enabling data backup and recovery, business continuity plans, cloud-based services and applications. From emails to entertainment streaming, our daily lives are built on data centers. But data centers are not “islands.” They need to be interconnected to share or back up data or to balance workloads. The success of the applications running over them depends not only on the performance of the data centers themselves but also on the connectivity between them. This is what the industry calls data center interconnect or DCI.
Security and availability are key
DCI networks have to transport enormous amounts of traffic, which often needs to be safeguarded from malicious cyberattacks and always available.
High-capacity data center interconnect networks
DWDM enables multiple signals to be combined and transmitted at different wavelengths on the same fiber pair, facilitating the transparent transport of multiple Terabits of data. Now, to tackle soaring data demand, enterprises and carriers have gone a step further and adopted coherent transport technology. Flexible and programmable coherent interfaces enable the maximum capacity-reach wavelength performance over any type of network infrastructure, leading to the lowest cost per bit. Other key factors besides system capacity are simplicity of network design as well as operational simplicity. Enterprises and carriers must be able to deploy and manage DCI networks with as little complexity and effort as possible. Other parameters like latency also play a vital role, particularly for enterprise DCI applications such as trading and business continuity between sites.
>>>>> Note: Coherent optical technology forms the foundation of the industry's drive to achieve transport speeds of 100G and beyond, delivering Terabits of information ... At its most basic, coherent optical transmission is a technique that uses modulation of the amplitude and phase of the light, as well as transmission across two polarizations, to enable the transport of considerably more information through a fiber optic cable. Coherent optics is a specific type of laser technology used by service providers to transmit large amounts of information over fiber optic networks. Coherent technology uses the three degrees of freedom (amplitude, phase and polarization of light) to focus more data on the wave that is ... <<<<<
