Product Overview
In response to the escalating demands of modern networking driven by cloud storage, AI, and 5G technologies, our 400G Coherent optical transceiver portfolio emerges as a comprehensive solution. The introduction of ZR/ZR+ optics means that WDM optics can now be integrated into IP routers in a cost-effective manner without reducing IP router port density. This allows the integration of a 400G-capable Digital Coherent WDM interface into the compact QSFP-DD form factor.
Three different Variants:
The portfolio encompasses 3 key offerings, each tailored to address specific challenges in data center connectivity and network efficiency.
