Fibre to chip connectivity specialist company acquired.

The acquisition of Teramount Ltd., the developer of detachable fiber to chip connectivity solutions optimised for high volume Co Packaged Optics (CPO) and other silicon photonics applications, has been completed by Molex.

“Teramount’s passive, detachable coupling approach supports large assembly tolerances and semiconductor grade wafer level processes—filling a critical gap in the optical stack,” said Aldo Lopez, president, Datacom Solutions, Molex. “By integrating this unique technology into our optical interconnect portfolio, Molex offers a more seamless path from early-stage prototypes to high-volume CPO and other silicon photonics architectures required for the AI era.”

Teramount will continue to operate as a design and engineering hub in Jerusalem (IL), supported by Molex’s global optical capabilities. It will become part of the Optical Connectivity segment within the Optical Solutions Business at Molex.

Financial terms of the transaction were not disclosed.

Co-oporative developments in next-generation optical communications.

Anritsu Corporation in collaboration with Fujikura Ltd., has measured inter-core crosstalk in weakly coupled multi-core optical fibres using multiple methods and has confirmed that the results are equivalent. Both companies presented their results at the international OptoElectronics and Communications Conference (OECC 2025) in Sapporo, Japan.

With the growing adoption of artificial intelligence (AI) and cloud services, the demand for higher transmission capacity in optical submarine cables and data centre interconnects is rapidly increasing. Today’s optical communications rely on single-mode fibre (SMF) and advanced signal optimization technologies to achieve high data throughput. However, as the transmission capacity per fibre continues to grow, these technologies are approaching their physical and performance limits.

Consequently, recent R&D has focused on weakly coupled multi-core optical fibre with multiple independent cores in a single optical fibre. While this type of fibre significantly increases transmission capacity, inter-core crosstalk – caused by interference resulting from light leakage between each core – degrades the quality of transmission. This varies not only due to the optical fibre design and manufacturing but also depending on the installation conditions, requiring evaluation of inter-core crosstalk in field conditions. Although various companies and research institutions have proposed different methods for measuring inter-core crosstalk, the measured results from each method have not yet been adequately validated.

In the presented comparative evaluation, Anritsu, in collaborating with Fujikura, measured inter-core crosstalk using four methods: two using optical power meters, and two using Anritsu's OTDR (Optical Time Domain Reflectometer) for measuring optical fibre loss and reflection. The evaluated four-core weakly coupled multi-core optical fibre manufactured by Fujikura features a standard cladding diameter of 125 µm. The measured results from each measurement method were all within ±1.0 dB at 1550 nm. Consequently, any of these four measurement methods can be chosen according to the weakly coupled multi-core optical fibre application scenario, such as R&D, Manufacturing, and Installation and Maintenance (I&M), with assured consistent correlation regardless of which method is used. Furthermore, these results will assist with future standardization of weakly coupled multi-core optical fibre.

Anritsu continues to contribute to the practical implementation of next-generation optical communications technology by providing test solutions for weakly coupled multi-core optical fibres.

Acquisition strengthens fibre capability.

Photona Group, the parent company to Laser Components, is expanding its expertise in the field of fibre technology by acquiring 100% of the shares in the Bavarian (D) fibre technology manufacturer FOC&T GmbH. The know-how and portfolio of both companies complement each other perfectly: While Laser Components has so far been focusing primarily on the industrial and aerospace sectors, FOC&T focuses on assembled cables for medical technology and has unique mechanical know-how in connector manufacturing. All jobs at FOC&T in Burghausen (D) will be retained.

Dr. Florian Blobner, Patrick Paul, Anton Pautz, Dr. Lars Mechold

Dr. Lars Mechold, authorized signatory and Technical Director at Laser Components Germany, is taking over the position of Managing Director from company founder and former Executive Director Anton Pautz. He will continue to be available to the company as a consultant in his retirement. "We are looking forward to a close collaboration with Mr. Pautz,"says Dr. Mechold. "He has shaped the company for more than 20 years and we are pleased that his expertise and knowledge of technical processes will continue to be available to us. This will ensure a smooth transition."

"By acquiring FOC&T, we are expanding our position in the market for fibre optic components," says Dr. Florian Blobner, Chief Product Officer at the Photona Group. "Both companies complement each other perfectly and these synergies will help us to open up new markets. We are delighted to welcome the new employees to the Photona Group and are sure that they will feel at home with us."

Power boost for single frequency infrared lasers.

TOPTICA's new highly reliable Raman fibre amplifiers (RFA) are based on patented technology. With their high power of up to 30 W the amplifiers cover the wavelength range from 1120 to 1370 nm that is not accessible by Yb or Er fibre amplifiers.

The all-fibre design requires no re-alignment and provides a high degree of stability. The RFA offers a wide tuning range of up to 10nm, a relative intensity noise >1% RMS (10 Hz- 10 MHz) and excellent long term RMS power stability of less than 0.5 % over 100 hours (with a TA pro seed laser). For wavelengths outside this range please enquire for a custom system. The RFA is designed using the company's high quality engineering excellence and utilizing a stable European & North American supply chain.

Key Features: • High power up to 30 W • Available at wavelengths between 1120 & 1370 nm •Wide tuning range of up to 10 nm • High reliability and maintenance-free platform design

The RFA is utilizing the proven and stable DL pro or TA pro as a seed laser, enabling a seamless integration into the TOPTICA environment of for example wavelength stabilization options. Utilizing a third-party seed laser of your choice is possible. Please inquire for requirements.

To reach visible and UV wavelengths the RFA can be integrated with TOPTICA 's SHG & FHG portfolio of frequency doubling and quadrupling systems. With these, high power in the visible wavelengths (for example more than 15W at 589nm) can be achieved while maintaining tunability over the entire RFA tuning range. For UV wavelengths the RFAs can be combined with FHG systems, drawing on TOPTICA’s extensive experience of custom (D)UV systems, while also maintaining the full tunability.

The system consists of two modules:
• The fibre Pump Module: Providing pump light for the RFA module.
• The Raman fibre Amplifier Module: High power amplifier module with inputs from the pump module and the seed laser.

Integrated polarization-maintaining (PM) adapters.

Laser Components is now selling feedthroughs that can be used to guide linearly polarized light into high vacuum and ultra-high vacuum chambers. Polarization-maintaining (PM) adapters have already been integrated into the flange. This allows patch cables to be connected quickly and without additional components.

In a wavelength range from 350 nm to 2000 nm, the feedthroughs provide a hermetic seal of 10-10 to 10-12 mbar l/s. The PM fibre is sealed via a special process, which ensures an extinction rate of more than 20 dB with minimal insertion loss.

“Our customers receive high-quality feedthroughs at an affordable price,” said Dr. Andreas Hornsteiner, head of Laser Components' fiber optics business unit. "There is no easier way to feed PM fibres into vacuum chambers, cryostats, and - for use in measurement technology - into vacuum environments."
