TRUMPF’s 980nm VCSEL extends transmission reach to 500m using optimized multimode fiber

TRUMPF Photonic Components GmbH of Ulm, Germany (part of the TRUMPF Group) — which makes vertical-cavity surface-emitting lasers (VCSELs) and photodiodes for the consumer electronics, datacoms, industrial sensing & heat treatment and automotive markets — has announced a transmission reach extended to 500m with its 980nm VCSEL and a multi-mode fiber optimized for this wavelength.

The results is being presented in more detail by Jochen Hellmig, head of Technology & Application Development at TRUMPF Photonic Components, during his presentation at the Optical Fiber Communication conference (OFC 2024) in San Diego, CA, USA (26–28 March). TRUMPF continues to make progress towards its long-wavelength VCSELs and photodiodes for applications requiring expanded specs for wider temperature range and enhanced reliability.

“As a pure-play supplier of VCSEL and photodiodes, we are partnering with customers to develop long-wavelength solutions that address applications such as automotive in addition to traditional data center,” says Ralph Gudde, VP of marketing & sales. TRUMPF says that it continues to invest heavily in its technology for 100Gbps and beyond. With fabs in Germany and Taiwan, the firm adds that it offers a more dependable supply chain to serve global demands.

Advanced optical data communication systems benefit from the high-speed data transmission that VCSEL-based technology offers. TRUMPF is offering both VCSELs and photodiodes as a matching-pair solution, in singlets, 1x4 arrays and 1x12 arrays for 14G and 25G for the NRZ applications. The same is offered for 56G PAM4 applications. The VCSELs are specifically designed to meet the demands of data centers, including for AI/ML, high-performance computing, and other bandwidth-intensive applications, as they deliver stable and reliable data transmission at high speeds.

Also at OFC, TRUMPF Photonic Components is exhibiting in booth 2000.
