TRUMPF showcasing updated 25G and 56G VCSEL technology and portfolio at OFC
In booth 2616 at the Optical Fiber Communication Conference and Exhibition (OFC 2023) in San Diego, CA, USA (7–9 March), 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, heating and automotive markets – is showcasing its recently updated VCSEL product portfolio and technology with matching photodiodes.
The firm is introducing the updated product portfolio of its well-established 25G and 56G components with extended temperature range and higher performances.
In addition, TRUMPF is showcasing a live demonstration on the performance of its latest VCSEL and photodiode components.
“At OFC 2023 we are also presenting progress on our 100G as well as our long-wavelength programs to address future demands,” says Ralph Gudde, VP marketing & sales.
VCSELs meeting the demands of data centers
Advanced optical data communication systems benefit from the high-speed data transmission that VCSEL-based technology offers, notes TRUMPF. For interconnect distances below 100m, VCSELs are the best solution in terms of power and cost, the firm adds.
TRUMPF is offering both VCSELs and photodiodes as matching pair solution, in singlets, 1x4 arrays and 1x12 arrays for 14G and 25G for NRZ applications. The same is offered for 56G PAM4 applications.
The VCSELs are specifically designed to meet the demands of data centers, high-performance computing systems, and other bandwidth-intensive applications, as they deliver stable and reliable data transmission at high speeds.
VCSEL technology for longer distances
TRUMPF says that it is investing in several technologies to extend the power, cost and reliability benefits of VCSELs for future applications. The developments include an extension to long-wavelength VCSELs as well as single-mode VCSELs with polarization gratings. The long wavelengths span 980–1310nm and even higher wavelengths, addressing longer-range datacom and automotive applications. Increased bandwidth, lower power consumption, additional multiplexing options and superior noise control are among the expected benefits from the developments of single-mode VCSELs and polarization gratings. The solutions continue to offer transmission at higher data rates and higher temperature, resulting in improved overall system performance, says TRUMPF.
