RtBrick brings in OpenZR+ support at 400 Gbps to remove need for separate transmission equipment

RtBrick said it has introduced support for OpenZR+ coherent optics within its disaggregated routing software at speeds of 400 Gbps, eliminating the need for internet service providers (ISPs) to have separate transmission equipment between their routers. This replaces fixed systems with a pluggable module that has a small form factor in an open switch that can also operate as a multiservice edge router. This lets operators simplify their architecture and optimise high-speed throughputs at distances of up to 480 km.

Hannes Gredler, CTO and founder at RtBrick, said adding this functionality at 400 Gbps means many ISPs can now completely remove their transmission systems, cutting operational costs and often boosting power efficiency.

Network disaggregation separates the hardware and software that is traditionally provided as a closed proprietary routing system, enabling operators to pick and mix different vendors and use low-cost hardware based on ‘off-the-shelf' components. Using RtBrick’s disaggregated routing software, operators can now leverage ‘white-box’ switch hardware instead of traditional and expensive 400 Gbps optical transmission systems. RtBrick said this development comes at a time when e-waste is projected to reach 74.7 million metric tonnes by 2030.
