Кабель DAC Breakout QSFP-DD в 2*QSFP56 2.5м - TS-QD400-2Q200-BDAC-CU2.5M TELSAR

Пассивный медный Breakout кабель прямого подключения 400G QSFP112 предназначен для использования в сетях 400GBASE Ethernet и InfiniBand (IB). QSFP112 представляет собой систему модулей и разъемов на базе текущего стандарта QSFP, разработанную для поддержки скорости 112 Гбит/с на канал в 4-канальной системе QSFP, что обеспечивает функционирование экосистемы соединений 400G QSFP. Данное решение существенно упрощает пользователям предыдущих поколений QSFP модернизацию пропускной способности каналов до 400G на порт при меньших затратах и минимальном времени перехода. Кабель обеспечивает передачу данных от каждой из двух пар медных проводников на стороне одиночного разъема QSFP112 (пары 1 и 2, 3 и 4) к соответствующим парам каждого из разъемов QSFP112 (пары 1 и 2) на многопортовой стороне. Соответствие стандартам SFF-8636 и SFF-8024. Соответствие спецификациям IEEE 802.3ck и QSFP112 MSA. Поддержка двухпроводного интерфейса I2C для удобства управления. Поддержка «горячей» замены (hot plugging). Низкий уровень перекрестных помех (crosstalk). Низкое энергопотребление. Длина линии: 2.5 м. Применение: 400G Ethernet. 400G InfiniBand. Коммутаторы и маршрутизаторы. Центры обработки данных (ЦОД), облачные серверы.
