About us

Founded in 1979, the company initially installed and built telecom satellite ground stations. For ESA it has designed a simulator for telephony switching in the sky and has built on-board electronics and high-efficiency power supplies for the XMM satellite that was launched in the year 2000 for a mission of 5 years, and which is still active, 23 years later.

In 1991 the Sparnex Engineering group developed world's first DSL chipset, which allowed high speed digital transmission over existing copper lines that were until then only used for voice communication. This technology enabled rapid growth of the Internet and GSM networks.

In 1996 the company launched the first fully programmable ITU-T copper loop network simulator LSX 2025 to simulate all properties of cable networks. The LSX simulators are the industry standard to test ITU-T interoperability and performance of broadband access modems. Sparnex is the only company that develops and manufacturers this type of simulators.

In 2003 the test & measurement activities were consolidated under the Sparnex Instruments brand, a spin-off of Sparnex nv.

Over the last 15 years the company has become deeply involved in the on-going development of next generation digital transmission technologies such as ADSL, ADSL2plus, VDSL2, and Vectoring. As an active contributing member of the Broadband Forum (BBF) https://www.broadband-forum.org/  Sparnex defines new test setup and simulation platforms according the ITU-T standards. The company is now focusing on the next big step: the G.fast technology that is running over existing copper networks at a speed that is faster than what is provisioned for each subscriber over fiber, and thus the ideal complement for next generation broadband networks.

Sparnex is the partner for studying new concepts, for transmission silicon/chip implementations, for PCB and product designs, for OEM and ODM support helping the industry with broadband transmission integration, going from technology and product proto-typing, up to full mass production of devices like SFPs, gateways, repeaters, Reverse Power Supplies,..

A team that realized an impressive list of hardware and software solutions over 40 years of broadband product design according to International Standards is at your service.
