TIA Issues Call for Interest on new Project for Measurement of Optical Power Loss of Installed Single-Mode Fiber Cable Plant
The Telecommunications Industry Association (TIA) TR-42.11 Engineering Committee on Optical Systems has issued a call for interest for document TIA-526.7-A initially titled ” Measurement of Optical Power Loss of Installed Single-Mode Fiber Cable Plant, Adoption of IEC 61280-4-2 edition 2: Fibre-Optic Communications Subsystem Test Procedures – Part 4-2: Installed Cable Plant – Single-Mode Attenuation and Optical Return Loss Measurement”.
TR-42.11 is developing guidelines in the area defined by the following scope: “This standard is applicable to the measurement of attenuation and optical return loss of installed optical fiber cable plant containing single-mode fiber. The principles of this standard may be applied to cable plants containing branching devices (splitters) and at specific wavelength ranges in situations where passive wavelength selective components are deployed, such as WDMs, CWDM and DWDM devices. This standard is not intended to apply to cable plant that includes active devices such as fiber amplifiers or dynamic channel equalizers.
Edge Computing vs Fog Computing: What’s the Difference?
Edge computing and fog computing allow processing data within a local network rather than sending it to the cloud, which decreases latency and increases security. The main difference between the two is processing location. With edge computing, data processing typically occurs directly on a sensor-equipped product that collects the information or a gateway device physically close to those sensors. Fog computing moves edge computing activities to local area network (LAN) hardware or processors connected to it. These may be physically farther from the data-capturing sensors compared to edge computing.
6 Reasons To Choose Fiber Optic Cable Over Copper Cable
When installing a network, one of the first decisions that technicians need to make is if they will be using fiber optic cable or copper cable. Although both copper cable and fiber optic cable can transmit an acceptable signal, fiber optic cable is the most desired choice with today’s growing bandwidth requirements over large distances. Below are six reasons why technicians should choose optical fiber over copper cable when installing their network.

Corning and AT&T expand pact on U.S. fiber broadband infrastructure
Based on AT&T’s long-term commitment to its network buildout, Corning said is investing $150 million in optical cable manufacturing in North Carolina, initially adding 200 jobs.
5 Questions to Ask Before Plunging into Edge Computing
The rise of edge computing means new ways of connecting, computing, and doing business. Companies are moving away from rigid, centralized computing models and toward a more adaptable and flexible distributed model. Before taking the plunge, ask these 5 questions.
Edge Computing: New Support For Digital Twins
Because simulation requires computational resources and the associated data outputs are large, cloud computing ― with its scalability and relatively low cost ― has traditionally been the technology environment of choice for supporting digital twins. But today, edge computing has emerged as a promising alternative. Edge computing leverages local resources that are close to the physical product’s location, which means reduced latency, while improving responsiveness, agility and privacy.
IoT News – The IoT, Together With the Evolution of 5G and Edge Computing, Is Driving Industrial Innovation

Specialty Optical Fibers Play an Increasingly Important Role
Specialty optical fibers are typically used in much shorter lengths than their telecom counterparts, averaging anywhere from a few centimeters to just a few meters in distance per application. These fibers are designed to be application specific, and can condition and amplify light in a way that traditional telecom optical fiber can’t, providing a necessary service so that networks can offer faster and more reliable connections.
