Оптический модуль TS-QSFPDD-400G-FR4 TELSAR разработан для применения в системах оптической связи на расстояниях до 2 км. Преобразует 8 каналов входных электрических данных со скоростью 50Gb/s (PAM4) в 4 канала оптических сигналов CWDM и мультиплексирует их в один канал для оптической передачи на скорости 400Gb/s.
На стороне приемника модуль осуществляет оптическое демультиплексирование входного оптического сигнала 400Gb/s на 4 канала оптических сигналов CWDM и преобразует их в 8 каналов выходных электрических данных со скоростью 50Gb/s (PAM4).
Центральные длины волн 4 каналов CWDM составляют 1271, 1291, 1311 и 1331 нм, являясь элементами сетки длин волн CWDM, определенной в стандарте ITU-T G.694.2.
Для обеспечения передачи по волокну на расстояние до 2 км требуется поддержка Host FEC (упреждающей коррекции ошибок на стороне хоста).
