Apakah perbezaan antara kabel rangkaian biasa dan kabel gentian optik?

Media penghantaran rangkaian biasanya dirujuk sebagai kabel rangkaian. Seperti yang kita sedia maklum, terdapat tiga jenis penghantaran rangkaian utama: 1. Kabel sepaksi; 2. Kabel rangkaian; dan 3. Kabel gentian optik berbanding kabel rangkaian biasa:

Perbezaan antara kabel gentian optik dan kabel rangkaian

1. Sifat yang berbeza: Kabel gentian optik dan kabel rangkaian berbeza dalam sifat, tetapi pada asasnya, ia adalah berbeza. Kabel gentian optik adalah konsep abstrak, mewakili kadar penghantaran maklumat dinamik; manakala kabel rangkaian adalah sederhana, pembawa untuk penghantaran maklumat.

2. Fungsi yang berbeza: Kabel gentian optik digunakan untuk mempercepatkan penghantaran pelbagai maklumat rangkaian; manakala kabel rangkaian digunakan untuk menyambungkan peranti, meningkatkan kecekapan penghantaran maklumat rangkaian antara mereka.

3. Bentuk kewujudan yang berbeza: Mereka sebelum ini wujud dengan cara yang berbeza. Kabel gentian optik wujud dalam bentuk maya, tanpa objek fizikal; manakala kabel rangkaian adalah kabel konkrit yang ketara.

Bagaimana untuk menyambung semula kabel gentian optik yang rosak?

1. Apabila menyambungkan kabel gentian optik, sambungkannya dengan teratur: kabel dengan warna dan teras yang sama, daripada terbesar kepada terkecil. 2. Apabila membuat sambungan, tanggalkan kabel optik. Berhati-hati agar tidak merosakkan tiub berkas. Selepas menanggalkan kira-kira 1 meter, beberapa gris akan muncul di dalamnya. Lap dengan kertas tandas.

3. Tanggalkan gentian optik dan masukkan ke dalam kotak sambatan, selamatkan dan ketatkannya.

4. Lulus gentian optik melalui tiub pengecutan haba.

5. Hidupkan kuasa dan lakukan penyambungan dengan penyambung gabungan. Berhati-hati untuk mengelakkan habuk dan serbuk gentian optik jatuh ke dalam penyambung.

Senario Aplikasi Gentian Optik dan Kabel Rangkaian

1. Senario Aplikasi Gentian Optik: Gentian optik digunakan terutamanya untuk komunikasi jalur lebar, menyediakan pengguna dengan maklumat multimedia interaktif seperti video, grafik, komunikasi dan data. Contohnya termasuk persidangan video, permainan interaktif dalam talian dan pengawasan video jauh.

2. Senario Aplikasi Kabel Rangkaian: Kabel rangkaian digunakan untuk menyambungkan peranti dan digunakan terutamanya untuk kabel kejuruteraan, sambungan rangkaian dan sistem pelabuhan peranti penyambung. Contohnya termasuk suis, hab, tembok api dan peranti lain. Kelajuan penghantaran gentian optik dan kabel rangkaian:

Kategori 7, kabel rangkaian terbaik, mempunyai frekuensi penghantaran sekurang-kurangnya 500 MHz, lebih daripada dua kali ganda daripada kabel Kategori 6 dan Kategori 6a, dan boleh mencapai kelajuan penghantaran sehingga 10 Gbps.

Kabel gentian optik kini merupakan media penghantaran terpantas, berkeupayaan 40G-100G.

Jarak penghantaran gentian optik dan kabel rangkaian:

Jarak penghantaran teori kabel rangkaian hanya dalam lingkungan 100 meter; jarak penghantaran kabel gentian optik: Modul mod tunggal 100Base-FX menggunakan gentian mod tunggal untuk menghantar 10-20 meter.

Perbezaan antara kabel rangkaian biasa (sering dipanggil kabel pasangan terpiuh) dan gentian optik boleh diringkaskan seperti berikut:

Feature	Network Cable (Twisted Pair)	Optical Fiber (Fiber Optic)
Alam semula jadi	Sederhana (atau pembawa), pembawa fizikal untuk penghantaran maklumat.	Konsep abstrak, mewakili kadar penghantaran maklumat dinamik.
Fungsi	Digunakan untuk menyambungkan peranti dan meningkatkan kecekapan pemindahan maklumat rangkaian antara mereka.	Digunakan untuk mempercepatkan penghantaran maklumat rangkaian yang berbeza.
Bentuk / Kewujudan	Kabel ketara, wujud sebagai objek konkrit.	Wujud secara maya, tanpa objek fizikal (maya) (walaupun kabel gentian optik itu sendiri adalah fizikal).
Kadar Penghantaran	Yang terbaik ialah Kategori 7 (Cat.7), dengan kelajuan sehingga 10 Gbps.	Pada masa ini media penghantaran terpantas, mampu 40G hingga 100G.
Jarak Penghantaran	Jarak penghantaran teori adalah dalam lingkungan 100 meter.	Lebih lama lagi (cth., modul mod tunggal 100BASE-FX menggunakan gentian mod tunggal boleh menghantar 10-20 km).
Senario Aplikasi	Digunakan untuk menyambungkan peranti; terutamanya untuk pendawaian kejuruteraan, sambungan rangkaian dan pelabuhan peralatan penyambung. Cth., suis penyambung, hab, tembok api, dsb.	Terutamanya digunakan untuk komunikasi jalur lebar, menyediakan maklumat multimedia interaktif seperti video, imej, komunikasi dan data. Cth., video mesyuarat kerja, permainan interaktif dalam talian, pengawasan video jauh.
