Kabel serat optik lapis baja

2025-09-24

Kata Pengantar

Serat optik, bahan yang fleksibel, harus menjalani pemrosesan untuk memberikan kekuatan mekanik yang cukup untuk beradaptasi dengan lingkungan yang berbeda. Perawatan ini melindungi serat dari kekuatan eksternal selama pemasangan, operasi dan pemeliharaan, sehingga memastikan operasi jaringan yang stabil. Namun, banyak kabel optik eksternal dan internal tidak memiliki perlindungan yang memadai di lingkungan yang kompleks, yang mengarah pada desain kabel optik terlindung untuk memecahkan masalah ini.

1. Ikhtisar kabel serat optik terlindung

Seperti namanya, kabel optik terlindung mengacu pada lapisan "baju besi" logam yang dipasang di lapisan luar kabel optik. Fungsi lapisan baju besi ini adalah untuk mencegah serat optik digigit oleh hewan, kelembaban atau kerusakan eksternal lainnya.

2. Mengapa memilih kabel serat optik terlindung?

Secara tradisional, kabel optik eksternal di tempatkan di saluran yang kuat untuk melindunginya dari kerusakan. Namun, metode pemasangan ini rumit, memakan waktu, melelahkan, dan mahal. Untuk menyederhanakan proses ini, para desainer telah memasukkan lapisan penguatan logam ke dalam kabel. Desain ini tidak hanya meningkatkan tekanan dan kekuatan tarik serat, tetapi juga memungkinkan penggunaan yang lama di lingkungan yang tidak bersahabat. Saat ini, kabel optik terlindung banyak digunakan dalam industri komunikasi optik.

3. Struktur kabel serat optik terlindung

kamar mandi

Jaket luar adalah garis pertahanan pertama untuk kabel serat optik terlindung, secara efektif melindunginya dari pelarut dan abrasi fisik. Biasanya, jaket luar terbuat dari bahan plastik seperti polietilen.

metal Armadura

Penguatan logam terletak di antara jaket luar dan dalam untuk melindungi dari pemotongan, mengunyah, dan pembakaran. Ini juga melindungi kabel selama pemasangan. Penguatan ini biasanya terbuat dari bahan logam yang kuat.

Kamar mandi dalam

Selubung bagian dalam melindungi kabel serat optik dan biasanya terbuat dari bahan pelindung dan penghambat api. Sederhananya, lapisan tutup kabel biasanya terdiri dari kawat aramid, selubung polietilen dan pita baja, memastikan daya tahannya.

4. Jenis kabel serat optik terlindung

Kabel optik lapis baja dapat dibagi menjadi beberapa kategori sesuai dengan aplikasi dan jenis perisainya.

Internal terlindung kabel optik

Kabel optik terlindung internal tersedia dalam dua jenis: kabel optik lapis baja satu lapis dan dua lapis biasanya digunakan di lingkungan dekat pantai dan perairan dangkal, sedangkan kabel optik terlindung satu lapis cocok untuk lingkungan umum lainnya.

Kabel Optik Lapis Baja Luar Ruangan

Kabel optik lapis baja luar ruangan dapat dibagi menjadi jenis yang ringan dan berat. Kabel optik lapis baja berat terutama digunakan di dasar sungai dan dasar laut, sehingga relatif mahal, sedangkan kabel optik lapis baja ringan lebih ekonomis dan praktis.

Interlocking terlindung kabel optik

Kabel optik terlindung yang saling berhubungan terbuat dari bahan pelindung aluminium dan cocok untuk lingkungan dalam dan luar ruangan. Mereka dicirikan oleh daya tahan tinggi dan ketahanan tekanan yang kuat.

Corrugated terlindung kabel optik

Kabel berpelindung bergelombang terbuat dari pita baja dan biasanya digunakan di luar ruangan. Mereka memiliki sifat mekanik yang sangat baik dan secara efektif tahan terhadap hewan pengerat.

5. Penerapan kabel serat optik terlindung

Tergantung pada lingkungan pemasangan, kabel optik terlindung dapat dibagi menjadi dua jenis: buffer longgar dan buffer ketat. Kabel optik terlindung buffer longgar umumnya digunakan di lingkungan luar ruangan, sedangkan kabel optik terlindung buffer ketat cocok untuk lingkungan dalam dan luar ruangan atau campuran.

Internal terlindung kabel optik

Kabel serat optik terlindung internal biasanya memiliki fitur penguatan logam yang saling berhubungan dan selubung luar yang terbuat dari bahan bebas halogen dan berasap rendah. Mereka banyak digunakan dalam jaringan telekomunikasi untuk menghubungkan bangunan.

Kabel Optik Lapis Baja Luar Ruangan

Kabel optik lapis baja luar ruangan umumnya memakai baju besi, yang memiliki kekuatan tarik tinggi, kekuatan tekan dan ketahanan hewan pengerat, dan cocok untuk digunakan di lingkungan yang keras.

VI. Ringkasan

Dalam komunikasi serat optik modern, setiap kegagalan serat dapat mengakibatkan kerugian finansial yang signifikan, membuat integritas serat pelindung menjadi penting. Kabel serat optik lapis baja, menambahkan lapisan logam pelindung ke serat, secara efektif memenuhi persyaratan gigitan hewan, kelembaban dan perlindungan peregangan, menjadikannya komponen tak terpisahkan dari sistem komunikasi modern.
