What are ROADMs?
Our ROADM technology, part of the FSP 3000 open optical transport solution, enables a more efficient and flexible optical networking infrastructure, simplifies
Roadam optical module
In optical communication, a reconfigurable optical add-drop multiplexer (ROADM) is a form of optical add-drop multiplexer that adds the ability to remotely switch traffic from a wavelength-division multiplexing (WDM) system at the wavelength layer. ROADMs allow network operators to access any wavelength at any node at any time, creating a new level of operational simplicity and flexibility. As network topology evolves, optical-layer grooming technology has progressed from FOADM to ROADM. The fixed optical add/drop multiplexer (FOADM) adds/drops wavelength signals at intermediate sites to manage specified wavelength signals (adding/dropping or pass-through). It enables adding (Add), dropping (Drop), or passing (Pass) optical channels remotely and flexibly without converting optical signals to electrical signals.
