What are characteristics of ROADM networking?

ROADM networking has several key characteristics. (B) Existing services are not affected while the network is being upgraded because ROADMs support in-service wavelength reconfiguration, allowing maintenance and upgrades without service interruption. (C) The power equalization function enables channel-level power equalization, which balances the optical power of each wavelength to ensure signal quality and stability. However, (A) While network maintenance efficiency is improved with ROADM, it is not guaranteed that wavelengths can always be efficiently modified without cost implications, and (D) network construction costs are generally higher due to advanced hardware requirements. HCIP-Transmission highlights these features to showcase ROADM’s role in flexible, resilient optical networking with minimal disruption.
