Optical communications solutions vendor Oclaro, has demonstrated interoperability of its 100G PAM4 electro-absorption modulated laser (EML) technology integrated into the 100G QSFP28 form factor the ECOC Exhibition in Rome. The transceiver was be part of the plug fest organised by the 100G Single Lambda Multi-Source Agreement (MSA). Oclaro also announced that sampling will begin later this year of its new high-density QSFP-DD solution, which uses this same 100G PAM4 EML technology in 4 lanes to enable an aggregated data rate of 425 Gbps.

“The breakthrough demonstration of the 100G single lambda optical link was made possible through the use of Oclaro’s world-class integrated indium phosphide (InP) 100G PAM4 EML technology,” said Yves LeMaitre, Chief Strategy Officer at Oclaro. “When combined with the latest generation DSPs, our high-bandwidth EMLs enable new transceiver designs for 100G per wavelength and 400G. Products such as Oclaro’s QSFP-DD are critical to hyperscale data centre operators to leverage a new generation of switching ASICs and allow for a faster migration to 400G.”

Oclaro says its 400G QSFP56-DD FR4 transceiver significantly reduces system cost per port by enabling 36 ports of 400G per 1RU compared to only 18 ports of 400G with CFP8 (1st generation 400G modules). To ensure interoperability, Oclaro has been actively involved in the 100G Lambda MSA and QSFP-DD MSA. In August of this year, Oclaro successfully interfaced the transceiver’s mechanical housing with leading QSFP-DD connector and cage vendors at the QSFP-DD MSA mechanical plug fest. Earlier this month, Oclaro also participated with its 100G QSFP28-FR and 400G QSFP-DD FR4 transceivers in an interoperability test organised by the 100G Lambda MSA.

Oclaro’s 100G PAM4 EMLs are fully qualified and in volume production and the company says it will begin shipping initial samples of the 400G QSFP56-DD FR4 during the fourth quarter of 2018 with volume production planned for the second quarter of 2019.

Earlier this year, it was announced that Oclaro had been acquired by photonics and laser developer Lumentum for US$1.8 billion in cash and stock.
