Dortmund, 15 December 2009. With the Expanded Beam lens connector technology it is possible to use fibre optic cables in the harshest of environments. In comparison with conventional connectors, lens connectors are far less susceptible to dirt, dust, shock and vibration, making them especially suitable for use in harsh environments, such as in military, broadcast or industrial applications.

Dortmund, 15 December 2009. With the Expanded Beam lens connector technology it is possible to use fibre optic cables in the harshest of environments. In comparison with conventional connectors, lens connectors are far less susceptible to dirt, dust, shock and vibration, making them especially suitable for use in harsh environments, such as in military, broadcast or industrial applications.
 
Fibre is considered to be a fragile and sensitive transfer medium. Conventional physical fibre optic connections are extremely sensitive to contaminants and the presence of even the smallest particles of dirt in the connector is enough to disrupt communication. Lens connectors were developed to minimise this susceptibility to dirt. They are used in situations where other components have long failed.
 
"As with all its products, in the area of lens connectors tde uses only the highest quality components and attaches particular importance to future-proof cabling systems, in order to provide the customer with predictability of planning for the next 10-15 years," said André Engel, CEO of tde - trans data elektronik GmbH.

Lens connectors are available in different sizes and numbers of channels - currently supporting up to 24 channels. In addition, the connectors can be used in broadband applications, and are therefore optimised for wavelengths of 850-1310 nm for multimode and 1310-1550 nm for single mode fibre.
 
tde can supply connectors that are compatible with conventional lens connectors, as well as "optical lens contacts" in the sizes 8, 12 and 16 for use in a variety of connector types. This means that mixed electrical/optical connection technologies can be combined in modular format. "The modular design and variety of heavy-duty optic connectors is currently unique in Europe, or even worldwide," said André Engel.
 
 
The lens connector principle
 
Lens connectors are based on the principle of beam expansion. Using this technique, the beam emitted from the end of a fibre optic cable is magnified by a ball lens to form a parallel beam that is between 140 (MM 50μ) and 2400 times (SM 9μ) its original size. When this beam strikes an opposing ball lens, it is focused on to the fibre once more. This expansion of the light signal while avoiding physical contact of the connector end faces means that the connector is not sensitive to environmental influences such as dirt, dust, shock or vibration.
 
The lens connectors used by tde are very easy to clean without special equipment and are also protected to IP67 when not connected. Therefore, the connectors are particularly well suited for demanding environments, from the military sector and outdoor industrial settings to coastal off-shore or mining applications.
 

Special solutions for harsh-environment applications
 

"Since no one application is just like any other, tde develops and manufactures customised cabling solutions according to its customers’ needs. These can also be provided inexpensively in small batches," explains André Engel.
