Our Inspiration - Our Aim 

Inspiration 

Our aim is the manufacture of 

technically leading products to the 

advantage of our customers. The term 

„engineering based“ defines exactly 

BKtel‘s orientation: Our organisation 

serves solely to optimally support the 

creativity and flexibility of product and 

system development. 

Aim 

Innovative services such as fast internet, 

“Voice-over-IP” and modern cable TV 

revolutionise everyday life, inspire the 

telecommunication industry and 

determine the future of the telecommunication 

market. BKtel supplies 

today its worldwide customer base with 

system solutions which they require in 

order to create and operate interactive 

networks successfully. The core of our 

business is the development, in 

accordance with market requirements, 

of technically leading components and 

systems, high standard manufacturing 

and reliable delivery. 

Our Company 

BKtel was founded 1997 as a result of 

a management buy-out from Alcatel 

Cable and has currently a workforce 

of approx. 100 employees worldwide. 

The company is based in two locations 

in Germany, the headquarters in 

Hueckelhoven-Baal, near Düsseldorf 

and a second office in Kornwestheim, 

near Stuttgart. Further international 

offices were founded in China and 

Japan for the growing Asian market. 

The company develops and manufactures 

products in the field of interactive 

FTTH-, Video Overlay-, RFoG- and 

HFC-networks for high performance 

data, telephone and cable TV services. 

The active and passive components 

are designed and manufactured in 

company-own facilities. The high quality 

products as well as the comprehensive 

support in designing optical networks 

make BKtel to one of the leading 

international suppliers in the FTTH and 

HFC market. 

Our Products 

BKtel develops FTTH, Video Overlay, 

RFoG and HFC broadband networks 

and related network management. The 

product portfolio includes a wide range 

of products starting from optical 

transmitters, optical amplifiers, optical 

receivers, optical return channel systems, 

customer premises equipment up to 

DWDM technology for upstream and 

downstream applications. The own 

manufacturing facilities guarantee 

a high quality standard (ISO 9001 

certified). Furthermore the company 

offers a complete range of services such 

as planning, installation and training. 

BKtel has enforced this philosophy 

consequently throughout the formation 

of the company and in day-to-day 

work. All tasks that do not directly serve 

research and development or the 

implementation of the products are 

carried out by third parties as services. 

As a result the organisation has a lean 

and efficient structure. 

This organisation, with a strict 

„production to order“ philosophy, is 

able to manufacture products, which 

not only offer our customers technically 

forward-looking solutions but also 

economical communication solutions. 

Outlook 

Innovative broadband networks will offer 

worldwide a sole platform for the fast 

and economical data, voice and cable 

TV services. BKtel in close cooperation 

with its customers will deliver systems 

and relevant network management, 

which will play a key role in the 

formation of these broadband networks.
