ПЕРЕХОДНОЕ ЗАТУХАНИЕ. ЧАСТЬ 1

Переходное затухание – разность между уровнем сигнала на одной паре или нескольких парах и уровнем помехи, создаваемой этим сигналом, на другую пару.

Часть передаваемой энергии переходит в электромагнитное излучение, которое попадает на соседние пары и снижает качество связи. В зависимости от места и метода измерения существуют различные виды переходных затуханий. Чем выше значение переходного затухания, тем лучше. Единица измерения – дБ.

NEXT (Near End Cross Talk, переходное затухание на ближнем конце) – переходное затухание, измеряемое на паре, находящейся на ближнем конце кабеля относительно источника сигнала.
NEXT не зависит от длины линии.

FEXT (Far End Cross Talk, переходное затухание на дальнем конце) – переходное затухание, измеряемое на другой паре, находящейся на дальнем конце кабеля относительно источника сигнала.
По мере увеличения длины линии уровень FEXT уменьшается, потому что кросс-толк ослабляется затуханием кабеля.

Значение NEXT всегда больше, чем значение FEXT.

P. S. Если кликнуть на картинку, то будет больше информации.

Can I mute a Telegram group?

In recent times, Telegram has gained a lot of popularity because of the controversy over WhatsApp’s new privacy policy. In January 2021, Telegram was the most downloaded app worldwide and crossed 500 million monthly active users. And with so many active users on the app, people might get messages in bulk from a group or a channel that can be a little irritating. So to get rid of the same, you can mute groups, chats, and channels on Telegram just like WhatsApp. You can mute notifications for one hour, eight hours, or two days, or you can disable notifications forever.
