Customer requirements: The customer has two equipment rooms with a distance of 100km. Optical transmission devices need to be configured between the two equipment rooms, and 100G service traffic needs to be transmitted between the equipment rooms. The customer requests the Fiongyitong team to configure a reasonable solution and device configuration.
As a professional OTN/WDM equipment and overall solution provider, we design a set of Optical Transport Network (OTN) solution suitable for telecom operators to transmit 100G services. In order to maximize the interests of customers, we need to consider several aspects. This includes network reliability, scalability, cost-effectiveness, and future upgrade needs. Here are some of the key steps in the design of XYTsharetop(XYT):
1. Demand analysis: First of all, we will have an in-depth understanding of the business needs of telecom operators, including service types (such as data, voice or video), transmission distance, and service quality requirements.
2. Network topology design: Design OTN network topology according to business requirements, such as ring, star or network structure. At the same time, considering fault recovery and network redundancy, the dual or multi-loop topology is designed to improve the reliability of the network.
3. Select the right OTN equipment: Select and configure the right OTN equipment according to the network topology and business needs, including OTN switch, optical amplifier, wavelength division multiplexer (DWDM), etc.
4. Wavelength planning: Allocate appropriate wavelengths for 100G services, and consider spectral efficiency and wavelength reuse to optimize transmission capacity.
5. Ensure and improve network performance:
- Adopt advanced coding technologies such as PDM-QPSK or 16QAM to support high rate transmission.
- Use forward error correction (FEC) technology to improve the anti-interference ability of the signal.
- Deploy XYT-EDFA optical amplifiers and XYT-DCM dispersion compensators to ensure signal quality over long distances.
6. Network Management and Monitoring: Implement a network management system (NMS) for monitoring network performance, fault management, and preventive maintenance.
7. Test and verification: After the configuration of all devices is completed, the Fibercom team will conduct a comprehensive network test, including the test of power level, signal-to-noise ratio, bit error rate and other indicators.
8. Training and delivery: Leinetong provides training to operators' technical teams to ensure that they can independently manage and maintain OTN networks.
9. Documentation and support: Weitcom will provide customers with complete design documentation and operation manuals to ensure continuous technical support after network deployment.
When designing the OTN solution, the XYT team not only ensures that the implementation of the solution complies with industry standards and regulatory requirements, but also considers future network upgrades and business expansion for customers to realize long-term return on investment.
Next, let's take a look at how to deploy an optical transmission system that can support long-distance transmission in order to transmit 100G of traffic between two equipment rooms 100km away. Here are some steps and equipment models for configuring optical transmission equipment:
1. Select a suitable device: For 100 GB services, use the OSN 8800 of Huawei, NCS 2000 series of Cisco, or 6500 Packet-Optical Platform of Ciena. However, the price of these devices and later upgrades may incur significant costs. If you consider the XYT2800 can not only support 100G transmission rate, and can meet the challenges of long-distance transmission, and has a great advantage in cost.
If you choose to deploy an optical transmission network spanning 100km using XYT's equipment, the main equipment and components may include the following:
- This is the main transmission platform, usually installed in a rack in the machine room.
- Used to amplify signals transmitted over long distance optical fibers. Install an optical amplifier in the appropriate position between the two rooms to ensure that the 100G signal can cover a distance of 100km.
- This module is responsible for processing 100G optical signals and performing the necessary encoding and decoding for transmission on the OTN platform.
Due to the long transmission distance, a dispersion compensation unit (DCM) is needed to manage and compensate the dispersion of the optical signal as it travels through the fiber.
2. Fiber selection: Because the distance reaches 100km, single-mode long-distance fiber is required, and relay amplification may be required. Select fiber with low loss characteristics.
3. Network device configuration:
- Port configuration: Configure 100 Gbit/s service ports on the devices in the two equipment rooms.
- Wavelength configuration: Select the right wavelength, usually in the C-band, to ensure high-quality transmission.
- Routing and switching configuration: Set appropriate routing policies and VLAN configurations to ensure that data is routed correctly.
4. Monitoring and management: Configure a network management system to monitor network status in real time, including power levels, optical signal quality, and device performance.
The configuration procedure is as follows:
- Install the 100G SPU XYT-LE5000.OU-100 on XYT-OTN2800 in each equipment room.
- Ensure that the single-mode fiber between the two XYT-OTN2800 devices has been laid, and test the quality and attenuation of the fiber.
- Install the XYT-LE5000-PA optical fiber amplifier at a suitable location on the optical fiber line, usually about 50km away from the signal source.
- Adjust the gain and other parameters of XYT-LE5000-PA according to the actual optical path and equipment manual to ensure that the signal still maintains good quality when it reaches the other end.
- Perform network configuration on the XYT-OTN2800 devices at both ends, including but not limited to wave length selection, service mapping, and protection and recovery policies.
- Finally, the entire transmission link is monitored and optimized through the network management system to ensure the stable operation of services.
Please note that this is a basic configuration example, and more details such as environmental conditions, power supply, etc. need to be taken into account during actual deployment. You also need to refer to the specific device documentation and support of XYT for detailed configuration and tuning. The specific device model and configuration depends on the specific requirements. Before configuration, it is very important to conduct detailed requirements analysis and network planning with XYT's professional technical team. If you also have similar network deployment needs, welcome to consult the XYT team.
