Memahami Skema Warna Kabel Serat Optik Dalam Ruangan第1张

Serat optik umum di banyak jaringan, dan sangat penting untuk menyediakan bandwidth dan kemampuan yang cukup dalam komunikasi digital modern. Jika Anda bekerja di jaringan, Anda harus mempelajari setidaknya dasar-dasar serat optik.

Jenis Kabel Serat Optik

Mode tunggal vs. Multimode

Untuk memulai pelajaran hari ini, kita dapat mengingat bahwa serat optik hadir dalam dua mode: tunggal dan multi. Serat mode tunggal lebih baik dengan komunikasi jarak jauh sementara serat multimode mampu meningkatkan tingkat transmisi keseluruhan.

Klasifikasi OM dan OS

Optik serat multimode menggunakan sebutan khusus OM1 melalui OM5 (dengan angka yang lebih tinggi mewakili kabel yang lebih cepat). Sementara itu, serat mode tunggal menggunakan OS1 dan OS2.

 

Dengan semua itu tertutup, setiap jenis kabel memiliki penunjukan warna, sehingga Anda dapat mengetahui dengan melihat jaket luar jenis serat optik apa yang digunakan. Di bawah ini, Anda akan melihat rincian lengkap jaket kabel serat ini dari warnanya.

Oranye

Warna jaket luar pertama dalam daftar adalah oranye. Oranye digunakan untuk kabel OM1 dan OM2. Jika Anda melihat oranye, Anda tahu itu salah satu dari keduanya, tetapi Anda mungkin tidak tahu yang mana. Anda dapat membedakan antara OM1 dan OM2 karena biasanya dicetak pada kabel.

 

Semua itu mengatakan, OM1 dan OM2 sudah tua. Anda tidak akan menginstalnya ke jaringan baru, tetapi Anda mungkin menemukannya di jaringan lama.

 

Aqua

Selanjutnya adalah aqua, yang merupakan warna jaket untuk OM3 dan OM4 (OM4 terkadang ungu, yang tercakup di bagian selanjutnya). OM3 masih berada di sisi lama sejauh kabel serat multimode pergi, tetapi Anda akan melihatnya digunakan lebih dari 1 atau 2. Beberapa jaringan mungkin melakukan lari OM3 terbatas untuk menghemat sedikit uang di sana-sini.

 

Adapun OM4, ini adalah titik awal Anda untuk optik serat modern. Dalam hal membedakan OM3 dari OM4, aturan yang sama seperti sebelumnya berlaku; penunjukan dicetak pada kabel.

 

Ungu

Terkadang, OM4 berwarna ungu, bukan aqua. Violet hanya digunakan untuk OM4, jadi sangat mudah untuk mengetahui apa yang Anda miliki ketika jaket serat Anda berwarna ungu. Perlu dicatat bahwa warna jaket bukanlah ungu tua. Itu ada di ujung merah muda spektrum ungu.

 

Hijau Jeruk Nipis

Pindah ke hijau limau, warna ini menunjuk optik serat OM5. Ini adalah serat multimode premium. OM5 dapat mencapai kecepatan data 100 Gbps. Ini masuk ke jaringan top-of-the-line, dan hijau limau adalah satu-satunya warna yang digunakan untuk menunjuk OM5.

 

Kuning

Kuning adalah sebutan untuk serat mode tunggal. Ada dua variasi utama untuk mode tunggal: OS1 dan OS2. Warna kuning yang sama persis digunakan untuk keduanya. Jika Anda melihat kuning, Anda langsung tahu bahwa Anda sedang bekerja dengan mode tunggal, tetapi Anda tidak tahu yang mana.

 

Aturan lama yang sama muncul lagi. Untuk membedakan antara OS1 dan OS2, periksa cetakan pada kabel itu sendiri.

 

Biru

Terakhir adalah biru. Biru bukanlah warna super umum untuk serat optik. Ini mengidentifikasi polarisasi yang mempertahankan serat mode tunggal. Ini adalah jenis kabel khusus yang mempolarisasi cahaya di kabel dan mempertahankan polarisasi itu.

 

Ini digunakan dalam aplikasi niche, dan sebagian besar jaringan tidak menggunakan optik serat biru. Tetapi jika kita melihat warna, Anda mungkin juga belajar tentang biru.

 

Urutan Warna Internal

Itu menutupi warna jaket eksternal, tetapi kabel serat memiliki komponen internal juga. Itu juga diberi kode warna, dan mereka mengikuti pola tertentu. Ada 12 warna untuk serat bagian dalam, masing-masing di bagian tertentu dari urutan. 12 warna tersebut kemudian diulang dalam urutan yang sama, tetapi memiliki garis. Dikombinasikan, urutan menggunakan 24 pola warna yang berbeda:

Urutan 12 Warna Dasar

Kesimpulan

Itu mencakup semua kabel serat dan warna yang berbeda dalam penggunaan modern. Beberapa warna yang dihentikan, seperti abu-abu, dikecualikan karena Anda tidak akan melihatnya sama sekali. Dengan panduan sederhana ini, Anda bisa mendapatkan gambaran yang jelas tentang jenis serat optik apa yang dimainkan sekilas.
