To simulate a fiber optic topology using OPNET that needs to configure optical links, to set up fiber-optic parameters, and examining high-speed data transmission. We offer a step-by-step guide to make and simulate a fiber optic network topology in OPNET:
Steps to Simulate Fiber Optic Topology Projects in OPNET
Step 1: Set Up the OPNET Environment
- Launch OPNET Modeler: We make a new project in OPNET Modeler.
- Create a New Network: Create a new network model by choosing the New Network option then name it and choose Wired scenario as per network type.
Step 2: Configure the Fiber Optic Network Topology
- Select Fiber Optic Components: Select optical components like fiber-optic transmitters, receivers, routers, and switches in the object palette. For replicating a fiber-optic network, these modules are essential.
- Place Devices in the Workspace: Organize the devices within the workspace look like the desired topology. General topologies for fiber optic networks that contains ring, star, mesh, and point-to-point configurations.
- Establish Fiber Optic Links: Link the devices to utilize the Optical Link tool. In the topology, optical links would denote the high-speed fiber-optic connections.
Step 3: Configure Link and Device Parameters
- Set Link Parameters:
- Data Rate: Fiber optic links are high-speed links thus consequently configure the data rate. Normal values range from 1 Gbps to 100 Gbps or higher.
- Propagation Delay: Fiber optic links contains low latency. Depends on the link length and speed of light within fiber (approximately 5 µs/km), we configure a realistic propagation delay.
- Attenuation and Amplification: Set up attenuation replicating signal loss over long distances. Amplifiers or repeaters can locate over the link to enhance the signal strength as required.
- Define Device Attributes:
- Configure the transmission power and receiver sensitivity at the optical devices designing real-world performance.
- If we are replicating the Wavelength Division Multiplexing (WDM) or Dense Wavelength Division Multiplexing (DWDM) for multi-channel fiber links then indicate wavelength parameters.
Step 4: Define Applications and Traffic Profiles
- Configure Traffic: Describe applications, which denote normal high-bandwidth traffic such as video streaming, bulk data transfer, VoIP over fiber optic links in the Application Config and Profile Config editor.
- Assign Traffic to Nodes: Allocate certain traffic patterns to each node utilizing the Profile Config editor. For instance, we may configure file transfers among two nodes or streaming applications over the fiber-optic backbone.
Step 5: Configure and Run the Simulation
- Simulation Configuration: In the Simulation tab, set up the simulation metrics like duration, granularity, and time step.
- Select Performance Metrics: Select the performance parameters which deliberate the fiber optic network performance like throughput, delay, jitter, packet loss, and link utilization.
- Run the Simulation: Execute the simulation then monitor the performance. For high throughput and low latency, fiber optic networks are modeled thus make sure that the network functions in these parameters.
Step 6: Analyze Results
- Review Performance Data: Utilize OPNET’s analysis tools estimating the fiber optic network after the simulation accomplishes. Significant parameters to concentrate on link utilization, delay, jitter, throughput, and packet loss.
- Optimize Configuration if Necessary: We need to modify metrics such as data rate, traffic load, or attenuation to attain the desired performance results depends on the discoveries.
