Verizon and NEC are providing further details of a proof-of-concept field trial in which the two companies used communications fiber-optic network cables as distributed optical sensor networks. NEC sensor technology attached to Verizon’s fiber-optic cable was able to collect information on city traffic patterns, road conditions, road capacity, and vehicle classification.
Carol Everett Oliver, RCDD, ESS, DCDC was chosen BICSI President-Elect. She will serve a two-year term as President-Elect, in 2020 and 2021, then will take the helm as BICSI President in 2022 and 2023. She will be the first woman to serve as BICSI President. Carol, who currently serves as BICSI’s Secretary, is principal of CEO Communications in Cape Coral, FL.
From measuring 5G to 4G handovers to testing signal distortion, executives from several top network-testing firms say that 5G is so dramatically different from LTE that operators are spending a lot more time testing their networks than in previous network upgrades. Interestingly, test equipment makers say that operators launching the non-standalone (NSA) version of 5G in millimeter-wave spectrum such as 28GHz and 39GHz are now considering moving to the standalone (SA) 5G version more quickly because of the complexity of non-standalone 5G.
To make things “smart” and improve overall efficiency, we connect IoT devices through a network to the cloud (and each other). Thus, anything “smart” requires connectivity, both wired and wireless, at least in most cases. The 5G networks of the future will bring sophisticated connectivity to these edge IoT devices with higher speeds, more machine-to-machine connections and very low latencies – enabling a new generation of applications and use cases that we haven’t yet thought of.
Crosstalk is the phenomenon by which a signal transmitted on one pair or one channel creates an undesired affect on another pair or channel. It causes interference on an affected pair of conductors or overall cable creates errors or prevents data transmission. But are you aware of the difference between the near end and far end crosstalk parameters you need to test for in balanced copper network cabling systems?
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.
Emerging standards to support Single-Pair Ethernet will have a meaningful impact in the smart building sector. Joining panelists from Analog Devices, Cisco, CommScope and Panduit, ACE IoT outlined how widespread adoption of Single-Pair Ethernet standards will help resolve long-standing challenges acquiring and deriving value from building operations data.
