TELSAR - зарегистрированный товарный знак компании ООО «ТВБизнес»
Оптический модуль TS-SFP28-25G-WDM-A-20 TELSAR форм-фактора SFP28 предназначен для передачи данных в одномодовом оптическом волокне (SMF) со скоростью до 25 Гбит/с на максимальную дальность до 20км. Рабочая длина волны 1270нм на передачу и 1330нм на прием сигнала, оптический бюджет 11 дБ, тип лазера: DFB. Модуль оснащен разъемом LC, поддерживает функцию Digital Diagnostics Monitoring (DDM) для контроля параметров производительности в реальном времени. Соответствует стандартам SFF8472, SFF-8431, SFF-8432.
Модуль TS-SFP28-25G-WDM-A-20 TELSAR предназначен для работы в паре с TS-SFP28-25G-WDM-B-20 TELSAR, но может также работать и с другими оптическими модулями SFP28 с обратным WDM делением длин волн приема/передачи.
Прошивка: CISCO. Если Вам требуется другая прошивка, сообщите об этом менеджеру перед заказом модулей.
