Всем привет! Какое максимальное достижимое расстояние у S+85DLC03DI? Мы заказали S+85DLC03D, но пришли именно S+85DLC03DI, и у нас проблемы с линками (периодические обрывы), которые стабилизируются, если отключить авто-нуготиэйшн и выставить скорость 1G. Линки между CRS328 и CRS317, расстояние примерно 50 метров. Почему S+85DLC03DI показывает sfp-link-length-50um равным 80 м, а не 300 м?
