Areas of use and applications Example telecommunications:

Crystals, SMD crystals, oscillators, resonators and filters are used in a variety of devices and infrastructures in telecommunications. These include routers with fiber optic, DSL, WLAN, Wi-Fi 6, Wi-Fi 7, LTE and 5G connections as well as powerline modems and powerline end devices. Typical applications also include switches for Gigabit LAN, 10 GbE, 100 GbE and 1000 GbE, industrial Ethernet switches as well as TSN and time-sensitive network switches. These frequency-generating components are also used in DECT telephone systems, DECT base stations, IP telephones, VoIP servers, gateways and mobile phone base stations for 5G. Other areas of application include network security, server infrastructure, LPWAN, non-terrestrial networks and numerous end devices such as media servers, NAS, smartwatches and drone control systems.

Precise frequency components are a central basis for stable data transmission in modern network technology. In routers, fibre optic routers, Ethernet switches and industrial Ethernet switches, crystals and oscillators ensure exact clocking and reliable synchronization. This is particularly important for high data rates such as Gigabit LAN, 10 GbE, 100 GbE or 1000 GbE, where even small deviations can affect the signal quality. An accurate frequency base is also crucial in TSN and Time Sensitive Network applications to ensure time-critical communication. These components therefore make a significant contribution to the performance, stability and availability of telecommunications systems.

SMD crystals and SMD oscillating crystals are particularly suitable for compact and powerful telecommunications devices with high demands on size and integration. Typical applications include routers with WLAN, Wi-Fi 6, Wi-Fi 7, LTE or 5G, as well as fiber optic end devices, repeaters, modems and smart home network components. They are also used in DECT base stations, IP DECT systems, VoIP telephone systems and mobile routers. Thanks to their compact design, they can be easily integrated into modern, space-critical designs without sacrificing precise frequency stability. This makes them an important solution for many current telecommunications and wireless applications.

Crystals and oscillators are indispensable for 5G, LPWAN and other wireless telecommunications applications because they provide the necessary frequency accuracy for transmitting and receiving units. They are used in routers with mobile radio, UMTS, LTE and 5G as well as in base stations for mobile radio networks and in wireless network solutions. A stable clock source is also crucial for TSN for wireless networks and resilient wireless networks in order to enable reliable communication. In LPWAN applications, these components support secure and efficient transmission over long distances with low energy requirements. They therefore form an essential technical basis for modern wireless and telecommunications systems.

Resonators and filters are used in many telecommunications systems where signal selection, frequency stability and reliable transmission are important. These include telephone systems, DECT systems, IP telephones, system telephones, VoIP communication servers and gateways. They also make an important contribution to network technology such as Ethernet switches, fiber optic switches, TSN switches and server infrastructures. In mobile radio applications, repeaters, base stations and wireless communication solutions, they help to process signals in a targeted manner and minimize interfering frequency components. In this way, resonators and filters support the performance and operational reliability of modern telecommunications solutions.
