We propose a flexible shared-per-group (SPG) architecture for wavelength selective switch (WSS)-based reconfigurable optical add/drop multiplexers (ROADMs) to support dynamic datacenter wavelength-convertible networks. The key components of this module are grouping installed tunable wavelength converter (TWCs) and tunable filter (TFs). Using the SPG architecture. the demands that coll... https://rbdoutlet.shop/product-category/girls-hoodies/
