2025

On April 1st, US time, the winners of the Lightwave Innovation Reviews, the annual innovation award in optical communications, were announced concurrently with the OFC exhibition, Changguang Huaxin 100G PAM4 VCSEL chip won the award.

Lightwave+BTR Innovation Reviews

is an annual innovation award hosted by Lightwave, a globally renowned media in the optical network field, aimed at recognizing the most breakthrough and influential products, technologies, and solutions in the optical communications field. The selection covers the entire optical communications industry chain, including technologies in optical transmission, optical access, data centers, and fiber infrastructure.

An independent jury composed of operators, technology suppliers, industry analysts, and academic researchers evaluates products that must have industry-leading technological breakthroughs or new application scenarios, significantly driving industry patterns or business models, and demonstrate high reliability and low power consumption verified by actual test data to stand out.

This award certifies product technological innovation, market influence, and performance advantages. Award-winning products usually become the direction of industry technology evolution and technical benchmarks!

Award-winning product

850nm 100G PAM4 VCSEL chip

Changguang Huaxin's 850nm 100G PAM4 VCSEL chip product was released in September 2024, matching top industry levels in key characteristics such as bandwidth and RIN:

Typical bandwidth at room temperature is 28GHz, typical RIN value < -150dB/Hz;
Wavelength < 863nm, meeting IEEE 50m OM4 multimode fiber transmission standard requirements;
Excellent anti-reflection performance ensures customer modules operate with no BER jumps across the full temperature range of 0-70℃;

Meets 400G VR4/SR4/AOC, 800G VR8/SR8/AOC applications. The product has completed reliability certification strictly according to GR468 standards. The wafer products have shown excellent performance and high yield in customer validation.

Iterative product

850nm 100G PAM4 VCSEL (SR)

On March 14, 2025, Changguang Huaxin released the iterative product 850nm 100G PAM4 VCSEL (SR), optimizing the original design to achieve an increased transmission distance from 50m to 100m, effectively improving wiring flexibility and space utilization, reducing relay equipment, lowering power consumption and operating costs, decreasing failure points, and enhancing system reliability and stability, representing the current leading level of domestic chips!

Both the awarded product and the upgraded iterative product will be exhibited at booth OFC1129. Inquiries are welcome!
