Televes’ business areas keep growing steadily, even if the challenges that we are currently facing are considerable. On top of that, the ever-evolving industry we operate in has been also experiencing notable disruptions due to the global pandemic – which has been among us for two years already.

Despite this, we continue to work to balance the well-established traditional market of communication infrastructures. Supported by our acquired technological knowledge, our future depends on the efficiencies of all of our business areas.

Our consolidated areas specialized in the fields of Hospitality, Professional LED Lighting and Optical Transport are showing a constant growth, to the point that we have been forced to rearrange our work groups to exploit synergies efficiently.

As a result, in early may, Televes Corporation opened a new workplace called Galileo – located in Santiago de Compostela (Galicia). The departments specializing in business, management, design, software and technical support will be backed by these areas to optimize resource organization and to boost work dynamics, while promoting cross-function expertise.

We are very excited about this milestone in our organizational growth. We really hope that this new corporate center boosts the talent of our colleagues from the areas of Hospitality, Professional LED Lighting and Optical Transport. Let’s follow the example of our traditional business area – TV Distribution – and build loyalty for more than 60 years.

The new workplace Galileo will boost cross-function expertise in the development of solutions and products of the business areas in the fields of Hospitality, Professional LED lighting, Optical Transport, as well as the Global Services support areas and software development.

Broadcast Operators search for key partners that can swiftly develop professional tools to manage and control their DTT ATSC 3.0 roll-out projects. Sinclair has found in Gsertel the perfect ally for their portable field spectrum analyzers.

Gsertel is the test and measurement subsidiary of Televes Corporation, providing dedicated technical support in the ATSC 3.0 roll-out in the United States through the Televes US subsidiary.

The Gsertel Hexylon field spectrum analyzer has been chosen by Sinclair for its versatility and real-time precision on any measurement required. The Gsertel engineering team's flexibility allows for new features to be developed promptly as the ATSC 3.0 roll-out generates new needs.

Hexylon is intended for professional users requiring advanced features and precise measurement accuracy, analysis and diagnostics of television and radio signals. Hexylon is not just a portable meter with a touch screen, but rather a new way of testing network signals, developed on the basis of a multi-touch screen. The content becomes the user interface and everything flows in an intuitive way using gestural commands.

The future of ATSC 3.0 is already here and it is very clear that Gsertel and Televes will play a starring role in this scenario.

Operators appreciate the dedicated and exquisite local support and knowledge we provide, letting our advanced technology take care of the rest. Good things are ahead for broadcast networks in the US and Gsertel and Televes expect to be a key partner in the ATSC 3.0 and SFN roll-out process.

The fields of use of our products often expand beyond the main use for which they were conceived thanks to the feedback we receive from our partners and the new applications that appear on the market. Thus, although the main application of our interactive TV system is still guest entertainment in the hotel room, it is now possible to remotely control the TVs without the need for a remote control and from a central control console.

This is very useful for TVs that are in common areas of hotels or other venues where you want to control centrally and remotely what content is displayed on screen.

Another area of application would be sports bars where there are several screens showing different live sporting events, and where using a remote control to control the TVs can be a problem, especially because: if the TVs are of the same brand the remote can act on all of them at the same time and not only on the TV on which you want to act. On the other hand, it also requires the remote controls to be located and it is not possible to perform a centralized remote control of the contents.

With our in-house developed STB Nemesis V2, this situation is solved, since it provides the system with the capacity for remote management of screens either locally or remotely.

There are basically two methods for joining two sections of optical fiber: mechanical splicing and fusion splicing. A mechanical spliceris an appealing option for occasional use. However, for professionals who regularly work with fiber infrastructures, a fusion splicer is undoubtedly the best choice.

The first thing to do to make a splice is to prepare the optical fiber cable; insert the heat-shrinkable cannula through the fiber and then proceed with the stripping. The usual stripping size should be between 3 and 4 cm in length. Once the fiber cover is stripped off, remove the first protection of 900 microns and then the second one of 250 microns. Once this process is completed, the next step is to clean the fiber (125 microns, and we recommend the use of the cleaning kit ref. 232710) and then proceed with the cut. For this purpose, place the fiber protective sleeve 16 mm from the cutting point and then close the cutter. Once the cutter is opened, remove the excess fiber from the collector and extract the optical fiber, which is now ready to be spliced. The same process is repeated with the second fiber, the fiber to be spliced.

Once both fibers are ready, they are passed to the splicer. Insert the first optical fiber on the V-groove and lock it. Follow the same procedure with the second fiber and then close the cover so that the splicing process can begin automatically. After this process, the screen shows the estimated attenuation losses (usually around 0.02dB) and the cover can be opened by removing the two spliced fibers. Before positioning the fiber in the oven insert the protective cannula over the zone that has just been spliced. The baking will be done automatically once the fiber is placed on it and the oven LED will turn off and beep when the process is finished. After this, just remove the fiber and place it in the upper zone of the splicer, the cooling zone.
