Today’s data center cabling infrastructure must be designed to offer a competitive advantage and a lower cost of ownership immediately. As a result, the evolution path to higher speeds such as 40G and 100G data rates, as well as next-generation applications such as cloud computing and virtualization, must be ensured early in the data center cabling infrastructure design and planning process. Find out how Altice Portugal has prepared for future #datacenter needs.
Stewart Connector’s new single and multiport RJ45 connectors to support 2.5G Base-T Ethernet communications. The new 2.5G connectors deliver a high speed, small form factor and PoE capable connector for use in networking equipment, IoT devices, servers, printers, and new emerging applications. The RJ45 connectors are optimally designed to address cross-talk and return loss issues that are common in 2.5G applications.
The Children’s Hospital of Wisconsin completed a 5,000 square foot data center project. The installation included From the data center’s core cabinets out of the MDF, there are 96 strands of SM fiber and 24 strands of 50um OM4 MM fiber. There is also 200 pair of copper connections back to the MDF. From the MDF, an equal amount of fiber connects out to the owner’s network. There are 3,504 strands of 50um OM4 fiber, for over 7,000 terminations. This fiber connects 46 individual server cabinets, as well as fiber distribution cabinets. All of this fiber is the Systimax instaPATCH pre-terminated cabling solution, connected to high density LC cassettes. There is also 144 Cat 6 copper cables that interconnect each POD back to the core.
In the recently published, ‘Silica optical fiber drawn from 3D printed preforms,’ the authors created single and multimode fibers that can be used to create designs and parts for a range of networks, likely related to telecommunications and Internet of Things (IoT) technology. Researchers investigated created a silica preform through both 3D printing and thermal processing—no small feat, considering it requires temperatures over T = 1900 ℃. To avoid this issue, the researchers tried using a lower melting polymer—a hybrid polymer-glass mix—via DLP printing.
Rosenberger OSI’s Identification Patch Cord (IDP) has been recognized as one of the best in the industry at the Cabling Installation & Maintenance Innovators Awards 2019. The IDP simplifies the manual patching of patch cords in distributors while preventing the wrong patch cord from being pulled. Thanks to an external light source, which is simply plugged onto the connector at one end of a patch cable to be patched, its other end can be unmistakably and reliably identified.
The City of Deerfield Beach, Fla., and Siemens recently announced the official start of a city-wide energy efficiency project to reduce the city’s environmental footprint. Last month, the Commission of Deerfield Beach approved a 17-year contract with Siemens for energy performance services. Valued at more than $9.2 million, the infrastructure improvement project will allow the city to reduce energy consumption in more than 20 of its facilities and increase the use of alternative energy sources. Energy and operational savings are approximated to be $15 million by the end of the 17-year project.
Cabling Installation & Maintenance is conducting a survey of professionals across the information and communications technology (ICT) industry, gathering information from consultants, design and installation contractors, end-user organizations, and industry vendors about plans and expectations for the future, as well as the current state of their business. Topics include the trade war and tariffs, the Internet of Things, 5G, and others.
Traditionally, single-mode has been limited to applications such as long haul, service provider networks, metropolitan area networks, and backbone distribution for large campuses. However, single-mode is now finding its way into shorter reach applications.In early 2018, Leviton surveyed network professionals about the type of fiber they would install today to plan for future growth, and found a significant jump in OS2 compared to surveys from previous years. This paper will address some prevailing preconceived notions about single-mode fiber — whether true or false — and provide guidance for single-mode testing, cleaning, and inspecting.
Using fiber optics is not the silver bullet, but it is the best option many have to keep their systems operating during natural disasters. Fiber networks—especially the ones built underground—are more durable than copper infrastructure, satellite and wireless. Fiber cables typically stand up very well to a weather event compared to a copper cable. Copper cables do not perform well when they are damaged and get wet. After Hurricane Sandy, Verizon started replacing the old, copper cables with fiber because of its operational robustness.
To improve the efficiency their municipal services, many Indian cities have started enabling government-service requests, which involves collecting and sharing citizen data with government officials and, potentially, the public. But there’s also a national push to protect citizen privacy, potentially restricting data usage. Cities are now beginning to question how much citizen data, if any, they can use to track government operations.
