- 3. suatu teknik transmisi yang yang memanfaatkan cahaya dengan panjang gelombang yang berbeda-beda sebagai kanal-kanal informasi, sehingga setelah dilakukan proses multiplexing seluruh panjang gelombang tersebut dapat ditransmisikan melalui sebuah serat optik
- 4. Konsep Dasar DWDM Dengan Penguat
- 5. • Optical Transmitter (Laser) Berfungsi mengubah masing-masing sinyal informasi dan memancarkan dalam panjang gelombang yang berbeda-beda λ 1, λ 2, λ 3,..λ n • DWDM Multiplexer berfungsi untuk menggabungkan sinyal-sinyal transmit yang mempunyai panjang gelombang berbeda-beda menjadi satu, untuk kemudian diteruskan ke satu satu optical fiber • Optical Cable Berfungsi untuk menyalurkan sinyal gabungan beberapa panjang gelombang, yang datang dari DWDM Multiplexer • Optical Amplifier Berfungsi untuk menguatkan sinyal optik yang sudah mulai melemah karena redaman sepanjang dalam perjalanan di dalam kabel serat optik. Satu optical amplifier dapat menguatkan beberapa sinyal optik secara bersamaan

- 7. media transmisi fisik yang terbuat dari serat kaca yang dilapisi dengan isolator dan pelindung yang berfungsi untuk menyalurkan informasi dalam bentuk gelombang cahaya
- 8. CORE Gelombang cahaya yang dikirim akan merambat dan mempunyai indeks bias lebih besar dari lapisan kedua, dan terbuat dari kaca. Inti (core) mempunyai diameter yang bervariasi antara 5 – 50 µm tergantung jenis serat optiknya Stuktur Dasar Fiber Optik
- 9. Cladding Bagian ini mengelilingi bagian inti dan mempunyai indeks bias lebih kecil dibanding dengan bagian inti, dan terbuat dari kaca Stuktur Dasar Fiber Optik
- 10. Coating Bagian ini merupakan pelindung lapisan inti dan selimut yang terbuat dari bahan plastik elastik Stuktur Dasar Fiber Optik
- 11. • Fibre Bending (Tekukan Serat) : Tekukan serat yang berlebihan (terlalu kecil) dapat mengakibatkan bertambahnya optical loss • Cable Bending (Tekukan Kabel) : Tekukan kabel pada saat instalasi harus di jaga agar tidak terlalu kecil, karena hal ini dapat merusak serat sehingga menambah optical loss • Tensile Strength : Tensile strength yang berlebihan dapat merusakkan kabel atau serat • Crush : Crush atau tekanan yang berlebihan dapat mengakibatkan serat retak/patah, sehingga dapat menaikkan optical loss • Impact : Impact adalah beban dengan berat tertentu yang dijatuhkan dan mengenai kabel optik. Berat beban yang berlebihan dapat mengakibatkan serat retak / patah, sehingga dapat menaikkan optical loss • Cable Torsion : Torsi yang diberikan kepada kabel dapat merusak selubung kabel dan serat

- 13. Serat Optik Multimode Step-Index memiliki core besar (50μm) dan dilapisi cladding yang sangat tipis. Penyambungan kabel lebih mudah karena memiliki core yang besar terjadi dispersi. Hanya digunakan untuk jarak pendek dan transmisi data bit rate rendah Multimode Step-Index
- 14. Cahaya merambat karena difraksi yang terjadi pada core sehingga rambatan cahaya sejajar dengan sumbu serat. Core terdiri dari sejumlah lapisan gelas yang memiliki indeks bias yang berbeda, indeks bias tertinggi terdapat pada pusat core dan berangsur-angsur turun sampai ke batas core-cladding Graded Index Multimode
- 15. Serat single mode mempunyai ukuran diameter core yang sangat kecil dan diameter cladding sebesar 125 μm dapat dilihat pada Gambar berikut. Cahaya nya merambat dalam satu mode saja yaitu sejajar dengan sumbu serat optik. Serat optik Single Mode Step-Index digunakan dengan bit rate tinggi Step-Index Single mode

- 27. Total loss fiber = Total panjang kabel x Loss kabel = 182 km x 0.22 dB/km = 40.04 dB Total loss konektor = Jumlah konektor x Loss konektor = 14 x 0.5 dB/konektor = 7 dB Total loss splice = Jumlah splice x Loss splice = 57 x 0.15 dB/splice = 8.55 dB Total loss daya = Total loss fiber + Total loss konektor + Total loss splice = 40.04 + 7 + 8.55 = 55.59 dB Pada perhitungan total loss daya merupakan penjumlahan antara total loss fiber, total loss konektor dan total loss splice. Dari perhitungan di atas diperoleh total loss daya sebesar 55.59 dB

Editor's Notes
- WAAS Express – A small-footprint, cost-effective IOS-based WAN optimization solution Key component of Cisco WAAS product portfolio Extend WAN Optimization solution across the entire ISR G2 family Increase the amount of available bandwidth for small to medium branch offices and remote locations, while accelerating TCP-based application operating in a WAN environment Natively use the capabilities of IOS software Fully interoperable with WAAS on SM-SRE modules, WAAS appliances, and are managed by a common WAAS Central Manager WAAS on the SRE platform - deployment flexibility, reducing the cost of operating WAAS at the branch office. The software deployment model enable remote and on-demand deployment at any time. You can deploy SRE in the branch office without any application when the router is being installed, and quickly provision WAAS at a later time, whenever customers are ready to turn WAAS on, or whenever the implementation plan calls for it. WAAS service can be turned on without on-site visit. One key benefit is that of modularity. All of the Cisco SRE hardware is independent of the host router resources. No router reboot is needed when installing WAAS on the SRE platform, reducing downtime and impact on network operations. New Branch appliances On the branch side, we have three different models. Everything now is called a WAVE or wide area virtualization engine. These platforms bring in more WAN bandwidth and provide more resources in terms of disc memory CPU for the Virtual Blades capability in the branch office. Additional resources allow more services to be virtualized in the branch. Both new Branch and Data Center platforms accept the high performance I/O connectivity options.

- Cisco WAAS enables organizations to accomplish these primary IT objectives: Cisco WAAS enhances productivity by mitigating the effects of WAN latency. Applications perform better. Data is transferred faster. Cisco WAAS reduces bandwidth consumption, delaying or eliminating increased recurring bandwidth costs. Cisco WAAS enables IT consolidation, reducing both capital and recurring expenses for branch IT infrastructure. Cisco WAAS delivers increased business agility by enabling IT consolidation and enhanced application rollouts without the risk of degraded productivity or added complexity. Ultimate agility is available with Cisco ISR G2 and the Services-Ready Engine (SRE), offering WAN optimization “on demand” as business needs arise. WAAS Express which provides “on demand” basic WAN optimization on Cisco routers may be considered on th ebarnch side as well. Cisco WAAS is deployed on an appliance, router-integrated service module on each side of the WAN to provide application-specific acceleration and WAN optimization capabilities. Cisco WAAS appliances can be deployed out of the data path or physically in-path in the data center or in the remote branch office, and Cisco WAAS network modules can be deployed out-of-path in the branch office. Regardless of the deployment model, Cisco WAAS provides application performance improvements and enables centralization without compromising high availability and scalability by providing intelligent load-distribution and fail-through operation.
