The dramatically grew in demand for 100G CWDM over the past year. While 100G continues to ramp, the promise of high volume 400G remains omnipresent, albeit a 2019 phenomenon. Customers need existing technologies that ship in production volumes to fill this industry gap. While 100G CWDM is a mature and well-understood technology and will continue to ramp in the coming year, many of the big Cloud Data Center OEMs are turning their sights to 200G, to meet the pressures of enabling faster connections at scale volumes. 200G optical transceivers with their many advantages such as significantly lower latency, power consumption and cost are coming to market now, and are seen by many as a viable, volume-scalable stepping-stone to 400G. The three hot selling 200G optical transceivers for the data center will be introduced in this article. 200G QSFP-DD SR8 NRZ QSFP-DD ports are backwards compatible with QSFP28 which is very important to provide a smooth upgrade path and links with older systems. The backwards compatibility of the QSFP-DD allows for easy adoption of the new module type and accelerate overall…
The Gigalight 200G QSFP-DD PSM8 10km optical transceiver module is designed for 2x 100G-PSM4 links over multiple single-mode fibers and supports transmission distance up to 10km using 1310nm wavelengths. The maximum power dissipation is 6.5W.
