Electronics for Networks That Never Go Down

From base stations to network switching infrastructure, fiber optic distribution systems to data transmission equipment, telecommunications electronics demand specialized packaging solutions in terms of high reliability and long service life requirements.

Björn Tech brings POLYRACK subracks, backplanes and system monitoring together with Innodisk's server storage, memory, network modules and Innodisk APEX edge AI systems. From the rack in the central facility to the edge site, every system is built from components whose fit has been planned from the start.

Recommended in this sector:

  • POLYRACK: Future and FrameTech subracks; CompactPCI Serial and PSB 2.16 backplanes; power backplane; FT 01/02 rack fan; SMC3 (monitors 6 fans, 8 voltages, 8 temperatures).
  • Innodisk: PCIe Gen4 SSD 4TS2-P / 4TS3-P (power-loss protected); EGPL-T102 10 GbE and PoE modules; DDR5 server memory; APEX-S100 (2U) and APEX-X100-Q (Qualcomm Cloud AI 100 Ultra): inference at the edge.

Telecom Requirements at a Glance

Areas of use Base stations, network switching, fibre optic networks, data transmission equipment and edge sites
Operation 24/7 for many years, often at unattended sites
Environment Central facilities and field cabinets, each with its own protection class and EMC requirements
Mechanics 19" subracks and enclosures with EMC-ready plug-in units
Backplanes CompactPCI Serial with 10G Ethernet, CompactPCI with Gigabit Ethernet, PICMG 2.11 power backplanes
System monitoring Fans, voltages and temperatures; automatic shutdown at overtemperature and remote control
Edge computing 2U short-depth AI servers, storage with power-loss protection, 10 GbE and PoE
Scope of supply Subrack, backplane, power, cooling, monitoring, storage, memory and edge AI from one supplier

Always On, Everywhere

  • High reliability

    Network infrastructure has to run without interruption; an equipment failure turns directly into a service outage.

    Our answer Power BackplanesSMC3PCIe Gen4 SSD 4TS2-P / 4TS3-P

  • Long service life

    Telecommunications equipment stays in service for many years; its mechanical infrastructure must remain supportable throughout.

    Our answer FuturePlug-In Units

  • Field and central facility conditions

    The same equipment may run in field cabinets and in central facilities, each with its own protection class and EMC requirements.

    Our answer FutureFrameTech

  • High data rates

    Network components need a reliable backplane and connection infrastructure for high-speed data transmission.

    Our answer CompactPCI SerialPSB 2.16

  • Unattended sites

    Base stations and field cabinets run with no staff on site. Fans, voltages and temperatures have to be watched remotely, and the system has to protect itself when cooling fails.

    Our answer FT 01/02SMC3

  • AI at the network edge

    5G and edge services process data close to users. Edge sites and regional data centres need server-class AI in short-depth racks.

    Our answer APEX-S100APEX-X100-QDDR5 Server Memory

  • Compact edge equipment

    Compact edge boxes have no room for expansion cards. Storage and network ports have to fit into M.2 slots, and cameras and access points should be powered over the network cable.

Racks, Enclosures and Cooling for Telecom

POLYRACK's 19" subracks have been a standard building block of telecommunications infrastructure equipment for many years. The subrack and enclosure lay the mechanical, EMC and protection-class foundation for field cabinets and central facilities; CompactPCI Serial and PSB 2.16 backplanes carry the data between the boards; power backplanes, fan units and SMC3 monitoring keep the shelf powered, cooled and under watch at sites where nobody is present.

At the network edge, Innodisk completes the system: data-centre SSDs with power-loss protection, server memory for short-depth systems, 10 GbE and PoE modules for compact edge boxes, and Innodisk APEX servers that run AI inference close to users.

The result: one bill of materials, one technical contact and a platform that can be extended and adapted over years of service.
