CWDM Optical Modules

4/8/16/18 Channel CWDM Optical Mux/Demux Modules

CWDM Mux/Demux модули являются двунаправленными пассивными оптическими мультиплексорами и демультиплексорами, которые разрешают оптическим сигналам с различными длинами волн пройти через один оптический канал. Предназначены для работы с FIO-1901, FIO-901 и FIO-991p серий оптических/электрических конвертеров CWDM, а также маршрутизаторами NVISION Grass Valley.

CWDM мультиплексоры/демультиплексоры объединяют/разделяют до 18 сигналов различных длин волн для различных типов оптических волокон. Блоки разрешают передачу различных сигналов, таких как AES, MADI, DVB-ASI, 3G/HD/SD-SDI или Ethernet в любом направлении по той же ВОЛС.   Скачать:  CWDM

Особенности

• 4, 8, 16 or 18 channel optical mux/demux
• Long distance coverage of multiple signals on a single fiber strand
• Various types of signals supported such as 3G/HD/SD, AES, DVB-ASI , Ethernet, etc.
• Same module can be used in either direction, allowing some channels in one direction and other channels in opposite direction
• Passive CWDM optical mux/demux design
• Minimizes content delivery costs where dark fiber is available
• Packaged in the same modular form as the FOS series of optical splitters, with all modules the same width, and configured to install in a convenient 1 RU tray that holds up to 10 single height modules or 5 double height modules, or any combination of both
