TDK Corporation has announced the development of the world's first 'Spin Photodetector', a component combining optical, electronic and magnetic properties responsible for processing data into optical fibre receivers. The device achieves an ultra-high response rate of 20 picoseconds (20 × 10-¹² s) using 800 nm light, providing more than ten times faster performance compared to traditional semiconductor-based photodetectors. TDK expects the new solution to become a key component in the developmen...

The most up-to-date software for the individual components of a video door entry system is usually a guarantee of trouble-free operation of the installation. We are talking about both basic functionality and, above all, the use of the equipment in more specific scenarios.

The Sendun SD-9+ is a fusion splicer that can be used to realise connections in various types of fibre optic networks: from short point-to-point links, subscriber connections, CCTV and industrial installations to GPON networks.

A signal booster, also known as a repeater, improves the coverage of mobile networks inside buildings. It works by capturing the signal from outside with an external antenna, amplifying it and distributing it indoors with an internal antenna.

When selecting the right model, it is worth taking into account several important factors: energy gain, directivity, mounting location, presence of a built-in signal amplifier and the band for which the antenna is tuned. Of these elements, the antenna gain and the TV band are the most important when selecting an antenna for DVB-T2 reception. Energy gain, most often expressed in isotropic decibels (dBi), is the parameter that determines how much an antenna exceeds its efficiency of a theoretical...
