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.
Most data centers typically use a mixture of direct connect and interconnect cabling. As the name implies, a direct connection runs point-to-point between racks. A data center interconnect routes patch cords to a presentation panel. For large projects, this strategy can become difficult to manage as patch cords tend to become longer and cable pathways grow more congested.
New user requirements and a steady demand for more capacity have created new test challenges across the optical network spectrum. These articles explore some of the more salient challenges as well as solutions, including the benefits of the right monitoring system, strategies for successful multi-fiber connectorization, and evolving data center test requirements.
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.
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.
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.
Active optical cables (AOCs) are used for short-range multi-lane data communication and interconnect applications. Usually, the wire transmission of optical communication should belong to passive part, but AOC is an exception. AOCs consist of multimode optical fiber, fiber optic transceivers, control chip and modules. They use electrical-to-optical conversion on the cable ends to improve speed and distance performance of the cable without sacrificing compatibility with standard electrical interfaces.
Should I outsource my data center operations?” The advantages of outsourcing data operations come down to three key factors: 1) cost, 2) uptime, and 3) security. You can expect to see drastic improvement to your IT team’s capacity and ability to support the business when you begin to outsource your data center operations.
Judging by the amount of traffic many people face on their morning commutes, anticipating demand and traffic flow is often the greatest stumbling block. My daily commute to work is a prime example: I’m stuck in the traffic on a six-lane highway where it converges into just two lanes ahead. As the car inches forward each time, I find myself repeating in my head “Who designed this highway?” Clearly, I didn’t think this was the most brilliant approach to improve traffic flow. Data center managers go through similar thinking processes when designing the network. The design stage is critical; it practically decides the outcome of a project, and most importantly, whether the investments are fully maximized.
