Expanded Beam contacts

Dortmund, 22 February 2010. tde – trans data elektronik GmbH, the leading manufacturer, distributor and systems supplier of networking equipment has rounded off its successful lens connector portfolio with the addition of innovative EBT "Expanded Beam Termini" contacts. 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.

Dortmund, 22 February 2010. tde – trans data elektronik GmbH, the leading manufacturer, distributor and systems supplier of networking equipment has rounded off its successful lens connector portfolio with the addition of innovative EBT "Expanded Beam Termini" contacts. 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.
 
"Expanded Beam contacts are no ordinary lens connector. The newly developed lens elements can be integrated into many common connector systems on the market using standard contact chambers," said André Engel, CEO of tde – trans data elektronik GmbH. He went on to say, "we are pleased to add this ingenious connector system to our range, making it available to customers from now on."
 

Expanded Beam contacts
 
The innovative aspect of the new expanded beam lens elements is that not only can they be integrated into various harsh-environment connectors, but they can also be used in a variety of other connectors.
 
The EBT lens contacts made by tde are provided in multimode and single mode variants and are available in sizes 8, 12 and 16. The connectors can be used for broadband applications, and are optimised for wavelengths between 850-1310 nm in the case of multimode fibre and 1310-1550 nm for single-mode fibre. This allows their use in WDM applications.
 
The lens elements can be used in standard connectors such as the military Mil-DTL-38999 or ARINC enclosures. These EBT lens elements can also be deployed in combination with electrical contacts for hybrid (electrical + optical) applications. Since the contacts do not require pressure, the insertion force is not increased by the use of lens contacts, so that only low insertion force is required, even with high numbers of contacts. In addition, thanks to the self-alignment of the ferrule, the lens elements have significantly improved attenuation characteristics.
 
EBT elements are very easy to use: The ends of the fibre optic cables that are to be connected are prepared just like traditional standard fibre optic connectors. Then it is simply a case of snapping one of the lens elements into the standard connector housing, as with an electrical contact.

 

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.
