PAM-4 chipset for single-lambda 100G, 200G and 400G data centre optical routing
The announcement is of a complete PAM-4 technology chipset for 100G data rates over a single wavelength enabling single-fibre and four-lane parallel fibre connectivity for 100G, 200G and 400G Ethernet applications. This chipset features a new transimpedance amplifier (TIA), transmit and receive clock and data recovery (CDR) devices and linear Electro-Absorption Modulated Laser (EML) driver module.
Increased traffic within and between cloud data centres is, MACOM observes, driving the need for low cost 100G, and for high-speed and low power 200G and 400G interconnects. To increase bandwidth density per port, data centre OEMs are adopting faster data rates starting in 2018. These interconnects will be supported with smaller QSFP, QSFP-DD and OSFP form factor modules, which require suppliers to deliver lower power electronic components. MACOM’s chipset addresses these power and bandwidth density needs by supporting single wavelength interconnects with EML lasers or silicon photonics, within the power envelope requirements of these smaller form factor modules.
“The major data centre operators are currently deploying 100G optics in volume to build their intra data centre switching fabrics,” said Ian Redpath, Practice Leader, Components, Transport and Routing at Ovum. “Today, the data centre intra-connect market is driven by the advances in Ethernet switch ASICs. As 400G switches enter the market, optical transceivers will need to keep pace and rapidly transition to 400G. Ovum projects the 100G equivalent data centre intra-connect market to grow at an explosive 56% CAGR by 2021 driving the need for low cost 100G over single lambda solutions. At the same time the industry will start adoption of higher speed 400G links also utilizing single lambda technology. We expect MACOM’s PAM-4, TIA, CDR and laser driver chipset will help drive these deployments.”
