Aerospace engines will help to power AI centres.
Long queues to connect or increase connection power - up to seven years - are forcing AI data centre developers to seek power on their own. Increasingly, therefore, turbines derived from aviation are appearing alongside server rooms. This solution is available faster than grid power, but is more expensive, noisier and more carbon-intensive.Engines originally designed for aircraft are finding new uses as local power sources. When the deadline for grid connection is distant, technology companies are opting for "behind-the-meter" power - power production directly at data centres. This allows AI to be developed without waiting for electrical infrastructure, albeit at the cost of higher emissions.

CF6-80C2 engine cores, originally used in Boeing 747s, are being upgraded to operate as land-based gas turbines. The resulting units, branded PE6000, deliver up to 48 MW of electricity per turbine, enough to power a medium-sized data centre or around 40,000 homes. The retrofit process includes extending the turbine sections to convert the engine thrust, installing additional supports and brackets and adding new control systems. Once assembled, the turbines are integrated into twin-turbine power units that include generators, air-cooling units, selective catalytic reduction systems and supporting electrical infrastructure.
The US authorities are beginning to see these installations as part of the security of the energy system. At the same time, experts warn of the environmental and economic costs. Energy from such generators can sometimes be up to twice as expensive as electricity from the grid. The popularity of AI is therefore increasingly based on a trade-off: fast access to computing power in exchange for higher costs, emissions and noise - at least until the power grids can keep up with the pace of investment.
Connecting an additional reader via RS-485 to Hikvision IP Villa door station DS-KV8113-WME1(C).
Hikvision IP Villa door stations from the DS-KV8xx3-WME1(C), DS-KV6xxx series have an RS-485 input that can be used to connect an additional reader. Such a reader can be mounted on the exit side of the property in the event that the customer does not want to open the gate using the handle or the local opening button. The DS-K1107AM G75369 can be used as an exit reader. Before connecting the reader, the corresponding address must be set on the reader (e.g.: 1) by moving the first DIP switch to the ON position. Then connect the reader via the RS-485 bus to the door station (yellow cable RS-485(+), blue cable (RS-485(-)). The power supply to the door station via PoE switch or 12 V/DC voltage and to the reader via 12 V/DC voltage is then required. Once the video door entry system has been properly configured and a Mifare (13.56 MHz) key fob has been added, applying it to the reader built into the door station or connected via RS-485 will trigger relay one at the door station and release the electric door opener.Collective multiswitch installations TERRA for HotBird 13.0 and Astra 19.2.
Collective multiswitch installations are a modern solution used in multi-family buildings, hotels, office buildings and other facilities where there is a need to distribute satellite and terrestrial TV signals to many receivers at the same time. Their main task is central reception of RTV/SAT signals and their even and independent distribution to individual premises or rooms.Multiswitch installation makes it possible to use one aerial set to serve many users, eliminating the need to install individual satellite dishes. Thanks to the use of multiswitches, each subscriber can independently select TV programmes, regardless of other users. This solution enhances the aesthetics of the building, tidies up the technical infrastructure and allows for easy future expansion of the installation.
The pictures below show a multiswitch installation based on TERRA switches.

The picture on the right shows an antenna set consisting of a satellite dish with a diameter of 120 cm and two QUATTRO type converters enabling reception of signals from two satellite positions: HotBird 13.0 and Astra 19.2. A COMBO-type directional antenna has been installed to receive DVB-T2 terrestrial television signals, while FM radio signals are collected using an omnidirectional antenna. The picture on the left shows the array with TERRA MV-924L R70874 multiswitches and SD-9xx series TERRA splitters.
Key advantages of TERRA multiswitch installations:
- no need for individual aerials on the roof - satellite and terrestrial signals go to all users from one aerial set,
- flexible expansion of the installation - further multiswitches and outlets can be installed as required,
- each user can independently watch satellite and terrestrial channels on their own receiver.
Rack cabinets in low current installations.
Rack cabinets are an indispensable component of telecommunications infrastructure, forming the basis for the organisation and installation of network equipment. In telecommunications, where reliability and efficiency are key, rack cabinets allow servers, switches, routers, monitoring equipment and other network components to be safely stored in an orderly and space-minimised manner. With their standardised dimensions (typically 19 inches), they allow for easy integration of a variety of devices, and also provide adequate ventilation, which is important for maintaining the correct temperature of equipment.RACK cabinets in telecommunications also provide protection against mechanical damage, dust and the dangers of unauthorized access. In addition, they allow easy organization of cabling, which not only promotes aesthetics, but also facilitates maintenance and diagnostics. Depending on your needs, the cabinets can be equipped with a variety of accessories, such as shelves, power strips, cable management systems or cooling systems. Thanks to such solutions, rack cabinets are the foundation of stability and performance of modern telecommunications networks.
All RACK cabinets offered by DIPOL can be found here.
One of the most popular RACK cabinets in the offer – 42U 600x800 mm standing cabinet SIGNAL R912014.
IEEE 802.3bt - PoE standard for higher-power network devices.
The IEEE 802.3bt standard, also known as PoE++ or 4PPoE, enables much higher power to be transmitted over an Ethernet cable. It makes it possible to power equipment with high power consumption - such as PTZ cameras with heaters, IP network speakers, laptops, monitors, lighting or information kiosks - without the need for additional power sources. This significantly simplifies installation, reduces infrastructure costs and increases network design flexibility.
802.3bt uses all 4 pairs, while 802.3af and 802.3at only use 2 pairs (which ones? - it depends on the end device)
IEEE 802.3bt is an extension of previous PoE (Power over Ethernet) standards such as 802.3af and 802.3at. It introduces the ability to power devices over all four pairs of wires in an Ethernet cable to increase the available power. The standard defines two new types of power supply:
- Type 3 - up to 60 watts of power per port (min. 51 watts available to powered device)
- Type 4 - up to 90 watts of power per port (min. 71 watts available for powered device)
| Parameter (unit) | IEEE 802.3af (Type 1) | IEEE 802.3at (Type 2) | IEEE 802.3bt (Type 3) | IEEE 802.3bt (Type 4) |
| Name | PoE | PoE+ | PoE++, 4PPoE, UPoE | 4PPoE, UPoE, High Power PoE |
| Power supply (PSE) (W) | 15.4 | 30 | 60 | 90–100 |
| Min. power for the device (PD) (W) | 12.95 | 25,5 | 51 | 71 |
| Number of twisted pair power supply pairs | 2 | 2 | 4 | 4 |
| Number of power supply pairs | 1 | 1 | 2 | 2 |
| Voltage Power Supply (PSE) (V) | 44–57 | 50–57 | 50–57 | 52–57 |
| Voltage for device (PD) (V) | 37–57 | 42.5–57 | 42.5–57 | 41.1–57 |
| Maximum current (mA) | 350 | 600 | 1200 (600 per power pair) | 1920 (960 per power pair) |
| Required cable | Cat. 5e | Cat. 5e | Cat. 6 | Cat. 6A |
The high available power not only proves its worth when powering demanding devices, but also makes it possible to create extended, serial connections of more PoE extenders. This is particularly useful when several network devices (e.g. IP cameras) need to be connected on a single UTP cable or when an additional network branch is needed. The lack of the need to supply AC 230 V to each point significantly reduces the overall cost of the installation and increases its security.
Transmission of the DVB-T2/C signal by optical fibre.
Providers of DVB-T2/C signal transmission by optical fibre usually use conventional optical transmitters and receivers, e.g. transmitter mo418 R82522 and receiver OD-005P R81760. Such connections use only separate cables with single-mode fibres, and the division of the signal for delivery to different locations is performed using passive optical splitters.An alternative solution is to convert the DVB-T2/C signal (coming, for example, from a headend) into an IP stream, transmit it over a traditional fiber-optic network (so-called active Ethernet), and then convert it back into DVB-T form. For such signal conversion, you can use:
- IPTV streamer sti441C TERRA R81592 which enables the conversion of 4 DVB-T2/C digital multiplexes to an IP stream
- IP transmodulator mix-440 TERRA R81611 which converts the IP stream to the DVB-T COFDM standard or IP transmodulator miq-440 TERRA R81631 which converts the IP stream to the DVB-C QAM standard
The IP stream itself can be transmitted via a fiber optic cable connecting any Ethernet devices - media converters, switches with SFP modules, etc. The advantage of such a solution is the possibility of transmission in both single-mode and multimode networks. Signal splitting is done on traditional switches, so in most cases there is no need to modify the existing network.
