ADVA has expanded its family of multiplexing optical modules with a 40km bidirectional design for access networks:

“So you need a multiplexing solution.... That includes differentiated products, products that don’t exist in the industry"

"As well as the -SR4 interface, the Quattro multiplexes 100-gigabit CWDM-4 and LR4. “Those are the two categories that don’t exist in the marketplace, so the product is unique,”"

“We are working with a partner on the packaging capabilities to reduce that massive number of lasers and detectors into small form factors,”
