Появилась необходимость получить в SFP порту коммутатора обычный медный гигабитный 1000Base-T, вместо оптики (обычно SFP используется оптическим модулем). Выбор пал на JT-COM, как самый дешёвый GLC-T/SFP-GE-T из доступных на Aliexpress и российском рынке, даже б/у.

Продавец после заказа связался со мной для уточнения, в каком оборудовании будет установлен модуль, указал что это будет D-Link и/или Mikrotik.

С момента покупки прошло 2 недели до получения посылки.
Заказ пришёл в пакете, где была коробочка, замотанная в пупырку.

Проверить трафик UDP не получилось, из-за технических проблем со стороны одного из участников тестового стенда.
После замера скорости установил в Mikrotik, что бы посмотреть как он определяется и что может рассказать о себе.

За 2 часа работы под нагрузкой SFP модуль нагрелся до 68 градусов цельсия.

Товар куплен за свои и соответствует моим ожиданиям.

Если необходимы другие тесты — пишите, попробую реализовать.
