AscentOptics’ coherent 100ZR cost-efficient, low-power 100G coherent QSFP28 for the optical edge. The ever-increasing growth in data traffic is forcing network operators to upgrade their edge aggregation infrastructure to 100Gbit/s rates. This can be a cumbersome and costly process. Operators need a solution that enables simple and cost-efficient upgrades without having to tear out existing equipment. With a low-cost and low-power QSFP28 design, our Coherent 100ZR pluggable transceiver slots directly into existing head-end devices, facilitating the adoption of 100Gbit/s coherent technology at the network edge without major changes in existing infrastructure, and at edge price levels.
