1. Introduction Optical fiber sensing takes advantage of the physical properties of light as it passes through the optical fiber to detect changes in temperature, strain and other parameters. Optical fiber has wide working frequency band and large dynamic range, which is suitable for remote measurement and remote control. It is an excellent low loss transmission line. Under certain conditions, optical fiber is particularly easy to accept the measured or field loading, and is an excellent sensing element. The optical fiber is electrically neutral, small in size, light in weight, ...

It is universally acknowledged that optical transceiver is widely used in the data center. That is because optical transceiver is playing a major role on data transmission. Therefore this article is written for make a brief introduction about data transmission. Descriptionthe Data transmission, also referred to as digital transmission or digital communications, is the movement of data over a communication medium from one device to another. In the form of a digital bitstream or a digitized analog signal, the process of data transmission is applied in different channels: point to point, poi...

As more fiber rollouts are announced across the U.S., the broadband industry is facing a looming problem: finding enough workers to actually deploy the tens of millions of new passings they’ve promised. Government statistics show the number of telecommunications workers has dropped drastically over the past decade and that figure isn’t expected to rebound anytime soon. But plug-and-play fiber installation technology could help alleviate the workforce crunch – at least to an extent.According to data from the U.S. Bureau of Labor Statistics (BLS), the number of telecommunications ...

There is a cause for optimism as the communications service providers (CSPs) enter their second decade of network transformation. That is the main finding of LightCounting's latest edition of its network transformation report entitled: Network Transformation Reaches a Pivotal Phase.On the surface, it is business as usual: CSPs are experiencing paltry growth and continue to search for new revenue opportunities. Yet under the surface, much is being done.Open RAN, a flagship network transformation project, encompasses all its key ingredients: disaggregation, virtualization, automation, a...
