The convergence of DWDM and routing technology — are 400G pluggable DWDM optics the key to this long-sought union? Let's take a look.

Coherent pluggable optics are revolutionizing networks by merging optical and IP layers, boosting capacity and efficiency while lowering costs. Interoperable modules, open line systems and high-power optics are key drivers. This shift enables significant savings and scalability for network operators, with the industry moving toward 800G and ultra-long-haul solutions. This technology is a major advancement in networking.

There are various transport network architectures, from strictly Layer 1 optical rings to meshed Layer 1 through Layer 3 converged networks. How do you decide? This article provides a high level overview of three different architectures, their typical use cases and benefits.
