100G PAM4 EML Lasers Meet Growing Demand High-Speed Interconnects

Oclaro’s 100G PAM4 EA-DFB EML chips target next-generation transceiver applications. The EML chips operating at 53 Gbaud with up to 40-Ghz bandwidth (at +20°C) and 6-dB extinction ratio (at +70°C) are suitable for use in pulse amplitude modulation-based (PAM4) transceivers, enabling 100 Gbps per wavelength. Combining high-performance and low power consumption, Oclaro's EML chips pave the way for the next wave of 200 Gbps and 400 Gbps in data center networks.

 

The high-speed 25G DML chips are well suited for 100 Gbps CWDM4 transceivers and have been produced in high volume for the last two years. They can also be used in low-cost SFP28 modules and other 25 Gbps products for high-volume, low-cost applications. Oclaro's EML devices provide the high bandwidth and linearity needed for next-generation 200 Gbps and 400 Gbps transceivers using PAM4, while still maintaining small size and low cost.

Fierce AI Week

Register today for Fierce AI Week - a free virtual event | August 10-12

Advances in AI and Machine Learning are adding an unprecedented level of intelligence to everything through capabilities such as speech processing and image & facial recognition. An essential event for design engineers and AI professionals, Engineering AI sessions during Fierce AI Week explore some of the most innovative real-world applications today, the technological advances that are accelerating adoption of AI and Machine Learning, and what the future holds for this game-changing technology.

 

The laser chips support both CWDM4 and LAN-WDM wavelength standards, and in many applications, uncooled operation and non-hermetic packaging can be employed for low-cost, high performance module solutions, including PAM4 transceivers for higher data rates. The 100 Gbps PAM4 EML chips are ready for sampling today. For more information, visit Oclaro.
