Production ramps for DustPhotonics’ 100-Gbps QSFP28-SR4 optical transceivers

DustPhotonics, an optical technology company facilitating data communications at up to 400 Gbps, says its QSFP28-SR4 optical transceivers are now available, and production of the transceivers has begun to ramp. The 100-Gbps optical transceivers integrate DustPhotonics' patented passive alignment technology to eliminate manual active alignment, resulting in minimized manufacturing cost.

According to the company, the QSFP28-SR4 is well-suited for short reach, high-density applications over multimode optical fiber in cloud, data centers, and HPC applications. As it begins accepting volume orders for the 100-Gbps optical module, the company says it plans to sample 400-Gbps transceivers later this year. The 400-Gbps transceiver product line will feature optical transceivers that are QSFP-DD and OSFP multi-source agreement (MSA) compliant, the company asserts (see "Preliminary QSFP-DD MSA optical transceiver specification released" and "OSFP MSA targets 400-Gbps optical transceiver module"). DustPhotonics demonstrated a QSFP-DD-SR8 transceiver at OFC 2018 this past March.

"The DustPhotonics design enables one versatile production line supporting all multi-mode form factors from 25 Gbps all the way to 400 Gbps," said Kobi Hasharoni, DustPhotonics CTO and co-founder. "This allows for optimization in creating a cost-effective, streamlined solution now and for future product generations to come."

In 2017, DustPhotonics was founded with venture funding from major private technology investors. The company's headquarters are in Modi'in, Israel, with business operations in Cupertino, CA.
