Source Photonics says it has shipped more than 2 million 28-Gbps EML laser chips, which are used to support optical transmission in applications such as data centers and 5G mobile network support. The company says it has yet to receive a field return of any such chips.
The 28G EML chip family reached commercial production in the first quarter of 2020 in support of Source Photonics’ 10-km QSFP28 100G LR4 optical transceivers. The chips subsequently have found use in a variety of modules using NRZ and PAM4 modulation to address applications ranging from 50G to 400G. These optical devices include 400G LR8/ER8, 100G ER4/ZR4, 200G LR4/ER4, 50G LR/ER, and other optical transceivers. The company says it now is investing to support applications at 800G and 1.6T transmission rates.
“We are excited to hit the 2 million milestone mark of 28G EML chips. Today’s announcement underlines our commitment and leadership in large-scale production capacity of high-speed EML chip and transceiver products,” said John Wang, CEO of Source Photonics. “Vertical integration remains Source Photonics’ core competitiveness. More than 90% of our transceiver products have transitioned to use our own optics chips now, including the newest 800G products under pre-production. We look forward to continue pushing the envelope to deliver higher speed EML laser chips for next-generation transceivers.”
"Strong demand for 100/400G optics in mega data centers has been making headlines over the last 3 years, attracting many new suppliers and technologies,” added Vladimir Kozlov, CEO and founder of LightCounting Market Research. “Source Photonics remains uniquely positioned to deliver its portfolio of 100G QSFP28 LR4 and higher performance transceiver products by vertical integration, which allows for faster deployment of next-generation 100/400GbE optical solutions in enterprise, data center, and service provider networks.”
