Analisis Jarak Terhadap Redaman SNR (Signal To Noise Ratio), Dan Kecepatan Download Pada Jaringan ADSL

Abstract

ADSL (Asymetric Digital Subscriber Line) adalah teknologi yang paling banyak digunakan untuk memberikan layanan broadband , lebih dari 60% pasar broadband di dunia menggunakan teknologi ini. ADSL merupakan sebuah teknologi yang tangguh, mempunyai kemampuan untuk mendukung aplikasi-aplikasi multimedia seperti voice, video, dan juga data. Konfigurasi ADSL juga sangat sederhana, cukup menggunakan infrastruktur jaringan lokal kabel tembaga yang sudah ada. Namun ADSL juga masih memiliki kekurangan, diantaranya jarak jangkauan untuk ADSL hanya berkisar ± 5 km. Selain itu, jarak pelanggan yang jauh dari sentral sangat mempengaruhi untuk nilai kecepatan download. Hal ini, dikarenakan semakin jauh jarak yang berarti media penghantar maka akan semakin banyak redaman yang terjadi pada media tersebut yang menyebabkan turunnya Signal to Noise Ratio dimana dalam hal ini dapat diartikan kekuatan sinyal. Sehingga dari hal-hal tersebut akan mempengaruhi kualitas kecepatan download. Dari sinilah yang kemudian akan dibandingkan bagaimana pengaruh jarak terhadap redaman, Signal to Noise Ratio, dan juga kecepatan download.
