INFO Televes turns 25
Being close to our customers is an identity trademark for Televes. 25 years ago, an initiative that sought to take an important step to fulfill this vocation was launched. Televes INFO bulletin was born with a first issue dated March 1991. That edition was modest in volume and content, but harbored the germ that has guided its development: to provide timely insight into the evolution of technology, report the news regarding the company´s catalog and to reflect the initiatives taken by Televes in key areas such as sector training.
Throughout these years, our INFO has grown in many ways. First, in variety of content. It has incorporated sections dedicated to answering technical questions; to show the increasingly active presence of the company in technical and commercial events; to provide useful ideas; to present installations that deploy advanced solutions, or display a touch of humor through photos with the most creative ways our customers use our products.
The development of the newsletter has been forged in parallel with the evolution of our company. Thus, with the exponential international growth of Televes, so too did the translated editions; the first was Portuguese 2004. Six years later, the international edition was launched with versions in English, French and Italian. The latest additions in Polish German and Russian make up a wide array of languages with some personalized content for each market. At the same time, INFO Televes has adapted to ever changing technologies and today is available from anywhere in the world through their digital editions.
It is now the time for a brief celebration of INFO 25th Anniversary. We thank you, the readers, for your continued loyalty and we renew our commitment to continue improving our newsletter and to continue at your side
Televes in the world
Andina Link (Colombia), CabSat (Dubai) and Mobile World Congress (Barcelona)
(Colombia) March 1-3
True to its commitment to Latin American markets, Televes attended this key event for the television and telecommunications sectors, which has reached 23 years of experience. Televes exposure was focused this year in the Hospitality industry, with FibreData solutions for GPON networks
(Dubai - UAE) March 8-10
This event is the perfect platform to open new business opportunities and strengthen ties with our customers in a very dynamic region, where Televes is well known and appreciated. Televes exhibited FibreData and CoaxData QuadPlay infrastructure solutions for the Hospitality sector
Mobile World Congress
(Barcelona) February 26-28
Televes presented CareLife, a comprehensive system that aims to improve the quality of life for older or dependant people at their homes, from the perspective of promoting an active and healthy aging process.
The presentation of CareLife was conducted jointly with Red Cross Spain within the spectacular Vodafone booth, where product demonstrations were held
TSuite en Play Store & App Store
The T.0X headends can now be controlled remotely through mobile phone apps for iOS and Android.
Tsuite and also its Windows version is now available in those platforms. Thanks to this the adjusting work and the remote monitorization of Televes headends will be now possible from smartphones and tablets. The installer will be able to provide immediate services of maintenance and installation
A traveler dish
It is very grateful to see how Televes can make wait times more pleasant.
In this image sent by Carlos Pérez, an installer from Socuéllanos (Ciudad Real), a satellite dish is placed on the top of the lorry cabin. We think that it is a witty way to provide entertainment in parkings or rest areas.
In this case the lorry just needs to be parked facing south
MMIC circuits: an exponential leap in component design and manufacturing
The immense possibilities offered by this technology enable a new generation of Televes equipment
and opens the door to diversification into highly technical and competitive sectors.
Making its own printed circuit boards (PCBs) has become one of several Televes brand traits, all driven by the historical need to employ self-sufficiency and technological development as a survival mechanism. When in 1983 Siemens decided to export its first Surface Mount Components (SMD) machine outside of Germany, it was Televes who acquired it. That investment in a technology that was virtually unknown in the industry, confirmed the company at the forefront of manufacturing.
True to its nature, Televes now goes a step beyond and has committed to designing and manufacturing its own line of components using MMIC (Monolithic Microwave Integrated Circuits) technology.
Once again, a huge leap forward that will give a substantial competitive edge to the company. MMIC drastically reduces constraints when designing advanced products. With traditional electronic components, designers must limit their requirements to the technical specifications offered by component manufacturers in their Integrated Circuit catalogs. With the MMIC technology, however, Televes can now produce its own components to whatever stringent and challenging specs defined. The designers now have their own imagination and industrial ingenuity as the only virtual limit.
Manufacturing the MMIC circuits is performed with compounds of semiconductors such as gallium arsenide (GaAs), gallium nitride (GaN) and silicon germanium (SiGe). Gallium arsenide offers advantages such as its ability to work at high frequencies and high resilience which prevents interference. Active devices, transmission lines and passive components devices can now be integrated on a single substrate, creating circuits so small that you must use powerful microscopes to handle them.
From a commercial point of view, MMIC component manufacturing will enable Televes to develop a new generation of equipment in the field of television signal distribution and measurement. But surely the progress goes further along, since it will boost access to sectors as technologically demanding as Avionics, Defense, Energy or Automotive.
This investment, vast and intense in human and economic resource allocation, is only available to a company that has innovation in its core DNA, and it confirms the strategic vision of Televes to remain a leader in its core business, while gravitating towards incipient emerging technological markets, an orientation led by the European Digital Agenda and within the framework of the EU Horizon 2020 Program
Planning a GPON installation with FibreData
The supply of telecomumnication services to hundreds of users requires an early planning.
Organising the process is key to save time and minimise errors.
A GPON network has some parameters that need to be configured in order to supply all the services by the OLT:
- To specify the services and the traffic type associated.
- In the image there are 5 services types and their associated traffic types.
2. DOWNLOAD TRAFFIC PROFILES
- To specify the bandwidth available for users. For each bandwidth is required to specify how the traffic is managed.
3. UPLOAD TRAFFIC PROFILES
- It is the same process as above.
4. ONU PROFILES
- To specify what ONT types there are on the GPON network. The OLT needs to know the interfaces and functions of each ONT type.
- In the example there are three products of the Televes' ONT range.
5. CONFIGURATION OF THE ETHERNET AND PON INTERFACES
- Each GPON service is associated to a VLAN. The tagging of each VLAN can be done from the router or from the OLT itself. Also each ethernet interface input can be associated to one or serveral services.
- Once the services, the interfaces and the profiles are associated, the OLT will recognise the ONT that is in the PON netwok. The administrator will have to set up them into the network.
7. ONU ACTIVATION
- The last step is to activate the associated services of each ONT. To do so you will need to access the web interface of each ONT which is also accesible through the VLAN “management” admimistrator or any other ZTC or TFTP tool.
If you know all the steps and parameters to be adjusted, the configuration of a GPON network is easier. The best way of a having a network managed efficiently is to have a good planning of the services and profiles
Did you know...
Marketing and Communications designer Carlos Rolando past away last February 3rd in Barcelona, at the age of 83. Argentine by birth, Rolando had been established in the catalonian capital since the late 60s, and from there he embarked on a path that would place him as an icon of his profession in Spain. Televes trusted him in the beginning of his career, and he is credited with one of the most successful decisions in the history of the company, at least from a marketing point of view.
Rolando was a great defender of adopting orange color Pantone 137 as the corporate identity and its application to satellite dishes. It was 1972 and building roofs began to be populated with the distinctive color that to date has been the authentic Televes flagship. Bestowed in 2005 with the National Design Award; Rolando was a great advocate of the role of visual elements in marketing and communication, and throughout his long career he developed countless logos and identifying icons for private companies, institutions and sector events. Amongst the latter, we recall the logo for the Universal Exposition in Seville in 1992 or, more recently, the image design for the Madrid 2016 Olympic bid.
We remember him for his bold vision, good craftsmanship and the great contribution he made to the Televes brand
Connecting satellite signal taking advantage of taps
The main advantage of taps is the possibility to interconnect them and attenuate the signal in order to reach a balanced network. For this reason some taps have the same outputs but different attenuations. Originally taps had not the current between the outputs and the input.
Televes has developed a wide range of taps which have the advantage of splitters (they have current between outputs and input) and also the advantages of taps (the adaptability of the attenuation to balance the installation) in just one device: the “all DC” taps.
An example of application would be an installation of TVSAT in which the sockets have different distances between them so that is required to balance losses. In this case a combination of three taps would fit in the installation even with a 1U panel (Ref. 530710)
Tap 5-2400MHz 4D “F” DC ALL
AWO Residenz (Cadolzburg - Germany)
In the AWO residence home in Cadolzburg (Bavaria), as the distance between the satellite dish and the headend is greater then 50 m fibre optic technology was the best option.
Within the first stage of the project, 220 users have received high quality TV. A 100 cm dish with an optical LNB (Ref. 2353) received the signal from Astra 19.2 º. This signal is transmitted by fibre to avoid losses and the conversion into RF is carried out by a converter (Ref. 237002). The RF signal is then injected into a 5x12 multiswitch connected directly to a Televes transmodulation headend which converts its DVB inputs into a 8 QAM multiplexes and also a DVB-T into a QAM. Once every channel is in QAM, an optical transmitter will send the signal to the different buildings using a 1310nm wavelenght and 10dBm of optical power.
In the first stage of the project, 5 building were commissioned. Once the optical signal is received, 16 optical receivers per building (Ref.2311 and 231201), this signal will be converted back into RF
