Eoptolink Samples Sub-10W 400G DR4/FR4 Transceivers Powered By Broadcom's 7nm PAM-4 Platform

Industry leading performance 400G QSFP-DD and OSFP DR4/FR4 modules integrating Broadcom’s 7nm Centenario PAM-4 DSP and 100G Electro-Absorption Modulated Laser (EML)

Chengdu, China (GLOBE NEWSWIRE) - via NEWMEDIAWIRE - Eoptolink Technology Inc., Ltd (SZSE: 300502) today announced the immediate availability of the world’s first sub-10W 400G QSFP-DD and OSFP DR4 and FR4 optical transceiver products. Enabled by Broadcom’s latest 7nm 400G 8:4 gearbox PHY device, the BCM87400, the new transceiver modules offer best-in-class performance while delivering unprecedented power efficiency enabling high volume deployment of 400GbE links in hyper-scale datacenter and cloud networks.

The DR4 and FR4 modules are fully MSA compliant and the full functionality of the gearbox and transceiver has been tested and verified together in 400G switches using the Broadcom® Tomahawk® 3 chipset with error-free operation and full interoperability. The DR4 modules support break-out applications with independent channel function for 4x100GbE enabling shuffle and aggregation applications using DR links. Eoptolink has also demonstrated 10km transmission distance that provides additional margin to the required 2km distance for FR4 transmission, showing a smooth way forward to support 400G LR4 applications when the standard is finalized.

With a typical power consumption of 8W in compact form factors, the new transceivers enable higher switch density and better system-level thermal performance, allowing network operators to cost-effectively transition to 400G Ethernet. Eoptolink's QSFP-DD's (EOLD-134HG-5H-M DR4 and EOLD-164HG-02 FR4) and OSFPs (EOLO-134HG-5H-M DR4 and EOLO-164HG-02FR4), enable simpler and cost-effective designs for equipment vendors and lower OPEX costs for network operators.

The transceivers are currently sampling with full general availability in Q2 2019. The 400G modules are based on Eoptolink’s proven technology platform already in use at several customers. The fully automated and vertically integrated production gives Eoptolink the ability to quickly ramp-up in high volume with high reliability.

“With the general availability of 12.8-Tb/s switches such as Broadcom’s Tomahawk 3, hyper-scale data center operators and cloud providers will be leveraging the 400GbE ports in these switches to address increasing demand for higher bandwidth. Our low power 7nm Centenario PAM-4 DSP is essential to support high density 400G connectivity using QSFP-DD and OSFP optical modules, accelerating the adoption of 400GbE network infrastructure. With Eoptolink sampling the first optical modules based on Centenario, hyperscale and cloud network providers can deploy high density 400G switches with the lowest power optics available delivering uncompromised performance,” said Lorenzo Longo, senior vice president and general manager of the Physical Layer Products Division at Broadcom.

“At Eoptolink, we are constantly improving the transmission performance of our modules to help our end customers. Broadcom’s 7nm DSP enables us to provide optical modules with the industry’s best performance at the lowest power. During 2018 the 400G ecosystem has been maturing and now all the sub-components for the transceivers are available in mass production. We are delighted to be the first transceiver manufacturer to offer these low power QSFP-DD and OSFP modules in high volume production thereby accelerating 400G adoption,” said Richard Huang, CEO at Eoptolink.

“Broadcom is committed to lead the evolution of Data Center interconnects from 100G to 400G by delivering end to end solutions with market leading performance and reliability. Optical module manufacturers are able to benefit from Broadcom’s complementary physical layer, PMD-IC and III-V Optical Component portfolio through consistent component interoperability driving shorter time to market and reduced design cost to advance the adoption of PAM4 solutions quickly and efficiently. Our industry-leading 100G EML is based on technology platforms with over 50 Billion device service hours in the field," said Mitch Fields, vice president and general manager of the Fiber Optics Product Division at Broadcom.
