Eoptolink Samples the Lowest Power 400G DR4/FR4 Transceivers for Hyper-scale Data Center and Cloud Networks

CHENGDU, China, January 29, 2019 – 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. 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 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-02 FR4), 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.
