tde lens contacts enable hybrid applications

Mon, 22 Feb 2010 10:35:00 +0100

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.

Ready for 100 Gigabit Ethernet with the tML® system

Wed, 20 Jan 2010 10:25:00 +0100

Dortmund, 20 January 2010. tde – trans data elektronik GmbH, the leading manufacturer, distributor and systems supplier of networking equipment, has made a significant extension to its successful "tML® - tde modular link" cabling system. The new MPO OM4 fibre optic module and the corresponding OM4 trunk and patch cables support bandwidth-optimised data transfer with a range of up to 550 meters – with minimal installation requirement on site.

For a long time, the international standardisation bodies only defined three classification categories for multimode fibre: OM1, OM2 and OM3. In order to meet the ever-increasing demand for bandwidth and range in data centres, the TIA committee adopted a fourth class, OM4, in August 2009.

"Unlike OM3 fibre, which can only achieve 10 Gigabit Ethernet over distances of 300 meters, the OM4 fibre can transmit data over a distance of up to 550 meters," explained André Engel, CEO of tde – trans data elektronik GmbH.

New OM4-optimised tML® modules and components

With the new MPO OM4 fibre optic module, tde is offering a laser-optimised module that meets the latest standards. The "aqua" coloured front mounted LC couplings allow simple network management, as do the rear-mounted MPO couplings.

The module includes MTP®/MPO trunk cable and LC patch cable, also supplied in the "aqua" colour coding and therefore easy to assign to the correct slots. If customers require, tde can also provide the OM4 fibre optic MPO trunk cable and LC patch cable using stress and bend-resistant Clear Curve™ fibre from the renowned manufacturer Corning. In comparison with standard fibre, this fibre has significantly improved bending properties and can therefore be laid around very small radii.

All OM4 modules and components are backward-compatible within the tML system and provide a considerable gain in range. Moreover, the concept of the single tML® system platform means that subsequent migration to future rates of, say, 40/100 Gigabit Ethernet is easily feasible. In contrast to the competition, all standard fibre optic connectors can be used with the tML system, and can even be accommodated and combined in a rack with RJ45 copper connectors with the same high port density.

The tML® - tde Modular Link System

tML® is a patented, modular cabling system that comprises three core components: Modules, trunk cable and module slot units. All system components are prepared and tested in the factory before being installed, mostly in data centres. The plug & play installation means systems can be up and running in the shortest amount of time. There are fibre optic and twisted-pair modules, and these can be used in mixed scenarios in a single module slot unit achieving very high port density. The heart of the system is formed by the rear-mounted MTP®/MPO and telco connectors, through which at least 6 ports can be connected at once using 10 GbE or GbE Performance.

Fibre optic connectors for extreme environments

Tue, 15 Dec 2009 10:08:00 +0100

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.

Maximum port density: tde integrates URM connection technology into tML® system

Thu, 19 Nov 2009 22:38:00 +0100

Dortmund, 18 November 2009. tde - trans data elektronik GmbH, the leading manufacturer, distributor and system provider of networking technologies now offers a new tML® fibre optic module especially designed for URM connectors, as a practical addition to its successful tML® - tde Modular Link system. In just one 1U casing, the new module houses 192 fibres, a density that had previously not been obtainable with URM systems.

“At tde, all tML® system components, whether they are modules, trunk cables or patch cables, are especially matched. Our new tML® URM module, therefore achieves a remarkably high packaging density for a URM system, in addition to very good levels of performance,” explained André Engel, CEO of tde - trans data elektronik GmbH.

The new tML® URM module

The tML® URM module has been designed with installation in the tML® module unit in mind. The 1U module unit contains slots for eight URM modules. On the rear of the modules there are two MTP®/MPO male connectors, while on the front there are three metal URM connectors, each of which holds eight fibres. This means that a total of 192 fibres can be carried in a single 1U unit. Despite the small form factor of the URM connector profile, this level of port density is currently unparalleled.

The slim MTP®/MPO trunk cable construction ensures the cable channels are reduced, improving ventilation and therefore permitting significant energy savings in the context of green IT. The matching URM patch cables can be obtained from LWL-Sachsenkabel GmbH and are can be prepared according to customers’ requirements. The URM connector system achieved 0.15 dB typical insertion attenuation and >55 dB typical feedback attenuation in single mode. An APC version will also be available soon.

Successful cooperation

The URM joints and prepared URM connectors are provided by LWL-Sachsenkabel GmbH. “The modular tML® solution from tde really impressed us. This combination of our two systems provides our customers with considerably greater levels of flexibility, and we will continue to include the tML® system in our product range in the future," said Lars Schumann, Sales Director of LWL-Sachsenkabel GmbH.

New 72 fibre module achieves 576 fibres in a single 1U unit

Wed, 21 Oct 2009 22:21:00 +0200

Dortmund, 21 October 2009. With the new 72-fibre tML® fibre optic module, we now offer a new, innovative module for the successful tML® - tde Modular Link cabling system. The 72-fibre tML® fibre optic module allows the highest levels of packaging density, with minimum installation effort on site.

Using the new tML® fibre optic module, when the patch panel is fully fitted with eight modules, it is possible to install 576 fibres in just a single 1U unit. The rear of the module contains a 72-fibre MPO connector, which internally distributes the 72 fibres through a fanout unit to six 12-fibre MPOs located on the front of the module.

This highly compact system offers great space-saving advantages, since it takes up just one twelfth of the space needed by traditional cabling systems. At the same time, the installation of cabling is extremely fast: Just one MPO connector can be used to plug & play 72 fibres at once – that produces significant time savings, which is obviously reflected in the installation costs for the cabling.

The matching 72-fibre trunk cable can also be obtained from tde. We only use MPO connectors with precision ferrules, since the manufacture of high-quality 72-fibre MPOs is a critical part of the system. Aligning the 72 fibres that lie closely packed together in the plastic ferrule in exactly the same way, to obtain the same performance from the connector that one would expect from a single-ferrule connector, demands wide-ranging experience and expertise.

The new tML® fibre optic module is available in multimode OM3+ format and is suitable for use in backbone cabling and cabinet-to-cabinet connections.

Most likely the smallest FO- fanout unit of the world for 144 fibers

Tue, 10 Jul 2007 11:39:00 +0200

The company tde has developed a new FO- fanout unit, that does not only cover the usual 12, 24 fibers, but now 144!!!

What is so special about this development is its size:
The diameter of the fanout unit for 144 fibers is just 42mm!
This FO- fanout unit can be terminated/ assembled with every current FO connector and, to be sure, will be delivered with a feeding support, like every other allocator too.

High performance plugs by the use of the "Lasercleaver"

Mon, 12 Mar 2007 11:46:00 +0100

Since January 2007 the new Comet Lasercleaver from Sagitta is used in the Fiber optic plug assembly process. Because of the use of this engine, not only the amount of assemblied plugs has arised, but the quality of the pollishing.

The Comet Lasercleaver is using a new, non-contacting Laser system, to cut accurately defined and to remove the glue dot off the ferrule. Because of this you achieve an extensive improvement of the quality of the final surface.

Furthermore you achieve a constant excess length of the fiber which makes an ideal grinding process possible, because of the use of this engine. Thus, the breaking of the fiber within the ferrule is a thing of the past. The consequence is a conspicuously improvement of the messured values. With this technics, tde has achieved a technological advance once again.

MPO in SAN environment

Mon, 12 Mar 2007 11:44:00 +0100

tde offers products for the fast and easy installation of high performance data processing centres and SAN applications. The combination of preconverted trunkcable assemblies and cassettes allow an easy "plug and gO" installation: the assembling of the cassettes, moving in and passing of the cables and the simple connecting of the cable to the cassettes. Networks can start running within only a few days with this technics.

You just need a minimum of training for this kind of assembly and cable laying. Furthermore there is no need of tools or other consumables and the working hours are minimated also for this installation.

All products are preconverted and tested under the best production conditions. Because of this reason, the high performance is assured for this application. In addition, tde has got standard components for every conventional cabling as a matter of course.
