DIAMOND SA - Rugged and reliable hybrid (optical/electrical) interconnect solutions

DIAMOND has been recognised as a worldwide leader in providing high precision fibre-optic interconnect solutions for more than 30 years. DIAMOND is also known as a dynamic and innovative company that is at the forefront of developing reliable and technically advanced solutions for a wide variety of industries and applications.

For many years, DIAMOND has been designing and delivering highly customised product to the military and defence markets.

DIAMOND offers a comprehensive line of rugged, high performance and practical fiber optic solutions specifically designed to provide maximum flexibility, modularity and durability in demanding condition when failure is not an option.

DIAMOND interconnect solutions integrates our Active Core Alignment (ACA) technology in our high performing optical interfaces, including: power solutions (PS), polarisation maintaining (PM), VIS/NIR, as well as, our DM hybrid (optical/electrical) insert, and in our custom optical assemblies.

DIAMOND's X-BEAM, MIL-38999 DM and MIL-83526 DM connectors, along with the ZEUS D50 HE fusion splicer are the most suitable and recommended for typical military and tactical applications.

In addition, DIAMOND has an independent accredited test and calibration laboratory that offers services, such as: fibre-optic instrument calibration, along with the measurement and testing of fiber optic components. Furthermore, DIAMOND's ISO 7 Cleanroom (Class 10,000 per FED STD 209E) allows for products to be cleaned and packaged in a controlled environment.

DIAMOND advanced fibre-optic technologies

DIAMOND utilises unique manufacturing techniques to provide advanced technology interconnect solutions for the most demanding applications.

Active Core Alignment (ACA)

To manufacture DIAMOND's high-performance connectors, only the highest quality materials are used. This is carried out in connection with our advanced fibre-optic component manufacturing processes, which have been developed over the last 25 years. Our target was to reduce the insertion loss values by minimising fibre-to-fibre eccentricity. The result is our patented two-part ferrule and "Active Core Alignment" (ACA) technology.

During this process, the end face is deformed after the fiber has been polymerised in place in order to centre the core of the fibre with the mechanical axis of the ferrule.


  • ultra-low insertion loss
  • unbeatable low IL for small core diameters
  • high return loss (RL)
  • can be applied to PM fibers, outperforms the IL performance of any other technology.

Power Solution (PS) contact optical interfaces

Diamond offers the power solution optical Interface which expands the MFD of a SM fiber by splicing a GRIN lens at the extremity. The MFD at the end of the connector is thus expanded by a factor of 4 to 5, increasing the contact surface by a factor of about 15. As a result the heat issues decrease but cleanliness of the connectors and mating adapters is still important.

Features and benefits:

  • improved power resistance (x16)
  • low insertion loss
  • ultra-high polish for high return loss.

PSb Ball Lens (X-BEAM)

A ferrule is placed behind a ball lens which is glued into a housing. This technology expands and collimates the transmission signal and reduces the impact of both misalignment as well as end-face contamination. Depending on the concentricity, the expanded beam exits the lens at a certain angle. To minimise this exit angle, Diamond uses the ACA process.

Polarisation Maintaining (PM)

The field of application of Polarisation Maintaining elements has expanded beyond traditional markets to brand new ones, from research to industrial environments: Biomedicine, Spectroscopy, Metrology, Sensorics, Telecommunications, Laser technology, Surveillance & Security, Defence and Lithography.

DIAMOND supplies high-quality solutions to polarisation maintaining (PM) and polarising (PZ) fiber optical interfaces for optimal control of the signal's polarisation state. Low insertion losses (IL) combined with high polarisation extinction ratios (PER) and higher return losses (RL) are achieved over very broad spectral ranges thanks to a combination of accurate optical and mechanical design.

Features and benefits:

  • Proprietary Active Core Alignment (ACA) process for minimal eccentricity between fiber's core and ferrule to guarantee unmatched low insertion losses
  • Active Polarisation Orientation (APO) procedure for optimal alignment between the mechanical connector's key and the true polarization (fast or slow) axis to guarantee the highest PER in a mated configuration
  • Optimised polishing techniques for excellent return losses values
  • 100% front face inspection.

VIS/NIR low wavelengths

Applications using non-telecom wavelength single mode and PM fibers exist in various sectors such as biomedical, measurement instruments, sensing and laser source and delivery.

DIAMOND offers the VIS/NIR optical interface for low wavelengths and small core fibres on most connector interfaces. Using DIAMOND Active Core Alignment (ACA) technology, we can achieve unrivalled low IL performances.


  • extremely low lateral offset for Low insertion loss
  • ultra-high polish for high return loss.
