Apakah Tepat Kabel 12 Teras?

Dalam telekom dan rangkaian, kabel gentian optik 12 teras ialah kuasa besar - ia membungkus dua belas gentian optik individu di dalam jaket pelindung tunggal. Fikirkan ia seperti lebuh raya besar untuk data: ia memaksimumkan lebar jalur sambil memastikan perkara padat, menjadikannya pilihan utama untuk pusat data moden dan rangkaian perusahaan.

Tidak seperti kord tampalan asas, kabel 12 teras membolehkan anda menghantar berbilang aliran data sekaligus atau menggabungkan sambungan menggunakan penyambung MPO / MTP. Ini semua tentang kecekapan dan kebolehskalaan.

Spesifikasi & Jenis Utama: Apakah Perbezaannya?

Apabila memilih kabel 12 teras, anda akan menemui dua perisa utama:

Mod tunggal (OS2):

Terbaik untuk larian jarak jauh (fikir kilometer, bukan hanya meter).

Mudah dikesan... ia mempunyai jaket kuning.

Sesuai untuk tulang belakang ISP atau rangkaian kampus yang jarak penting.

Multimod (OM3. OM4. OM5):

Dibina untuk data jarak dekat dan berkelajuan tinggi (sehingga 550 meter).

Warna jaket berbeza-beza: OM3 ialah aqua, OM4 ialah erika violet (atau kadangkala aqua), dan OM5 adalah - baik, ia adalah standard yang lebih baharu dengan rupanya sendiri.

Ideal untuk sambungan pusat data dalaman di mana kelajuan dan ketumpatan adalah kunci.
