How digital transmission analyzer improves the transmission quality of digital communication signals
With the rapid development of the information age, digital communication technology has become an important way for human information exchange. Whether it is mobile phone communication, Internet access, or IoT device interconnection, these all rely on high-quality digital signal transmission. However, in practical applications, digital signals are often affected by various factors such as noise, interference and attenuation during transmission, resulting in reduced transmission quality and data transmission errors. Therefore, it is particularly important to improve the transmission quality of digital communication signals. In this regard, digital transmission analyzers have become one of the key tools.
Digital transmission analyzers are the most important and basic test instruments in digital communication. They are mainly used to analyze and measure various signal parameters in digital communication systems and test the transmission quality of digital communication signals. The main test parameters include bit error, alarm, overhead, jitter and drift, etc., which are widely used in the development, production, maintenance and measurement testing of digital communication equipment, and can also be applied to the construction, commissioning acceptance and maintenance testing of digital communication networks.
Common Functions Include:
1. Bit error test: It is a test method used to evaluate the performance of digital communication systems, which aims to measure the bit error rate that occurs during transmission. Through bit error testing, engineers can evaluate signal transmission quality, identify potential problems, optimize system design and parameter settings, and improve the reliability and stability of digital communications.
2. SDH/SONET testing: SDH (Synchronous Digital Hierarchy) and SONET (Synchronous Optical Network) are two synchronous digital transmission standards widely used in transmission networks. They provide high-speed and reliable data transmission capabilities and are widely used in fields such as telephone, Internet, and data communications. SDH is mainly used in Europe and Asia, while SONET is mainly used in North America. In digital transmission networks, SDH and SONET testing is an important part of quality assurance and performance testing of these two standards. It aims to evaluate the performance of SDH and SONET transmission systems to ensure that the network operates normally and meets the requirements of the specifications. The SDH/SONET test function mainly includes the following aspects:
Bit error rate test: Detect the number of bit errors that occur during transmission in the SDH/SONET network to determine the bit error rate, thereby evaluating the reliability of the system.
Performance monitoring: Monitor the performance parameters of the network, such as signal quality, clock synchronization, etc., to ensure the normal operation of the network and respond to potential problems in a timely manner.
Jitter: Analyze the jitter phenomenon in signal transmission, evaluate the stability of the clock signal and its impact on data transmission performance.
Overhead: Refers to the additional information or control information in the transmission system in addition to user data. These overheads include additional data for synchronization, management, protection and error correction purposes.
Alarm: Refers to the alarm signal generated when a system fails or is abnormal. These alarm signals are used to notify network administrators or maintenance personnel that there is a problem in the system and that it needs to be handled in a timely manner.
3.DSN/PDH test: DSN (Digital Signal Network) is a data transmission network, while PDH (Plesiochronous Digital Hierarchy) is a technology for transmitting digital signals at different rates. In the field of digital communications, DSN/PDH testing is a test activity used to evaluate and monitor the performance and quality of digital signal transmission networks. The DSN/PDH test function mainly includes the following aspects:
Transmission quality test: Evaluate the quality of signals in the transmission network through testing, including parameters such as bit error rate and jitter, to ensure the stability and reliability of signal transmission.
Clock synchronization test: Test the clock synchronization performance of each node device to ensure that each device in the network can work in coordination and maintain the accuracy and synchronization of data transmission.
Troubleshooting and diagnosis: Find fault points in the network through testing, troubleshoot and repair them in time to ensure the normal operation of the network.
Performance monitoring and optimization: Monitor the performance parameters of the network, find performance bottlenecks in the network and optimize them to improve the transmission efficiency and performance of the network.
Connection integrity test: Test the connection status and integrity of the transmission line, confirm that the connection between each node device is normal, and ensure smooth and reliable data transmission.
4. OTN test: OTN (Optical Transport Network) test is an important function in the digital transmission analyzer, which is used to evaluate and monitor the performance and quality of the optical transmission network. The OTN test function mainly includes the following aspects:
Interface test: Test the interface of the OTN network device to check the connection status and normal working status of the interface.
Clock synchronization test: Test the synchronization performance of the clock signal in the OTN network to ensure the normal clock synchronization between each device and the accuracy and synchronization of data transmission.
OTN frame structure analysis: Analyze the OTN frame structure, check the frame header, payload and error correction code, etc., to ensure the integrity and correctness of signal transmission.
Optical power test: Test the power of the optical signal to ensure that the intensity of the optical signal is within the appropriate range to avoid the optical signal power being too large or too small to affect the optical transmission quality.
OTU (Optical Transport Unit) performance test: Perform performance tests on OTU, including bit error rate test, eye diagram test, etc., to evaluate the transmission quality and stability of OTU.
Performance monitoring and optimization: Monitor the performance parameters of OTN network, such as signal quality, clock synchronization, etc., find performance problems in the network and optimize them to improve the transmission efficiency and performance of the network.
In addition to these functions, digital transmission analyzers also have MSTP analysis, PTN/IP RAN analysis, SyncE analysis, and IEEE1588v2 PTP analysis functions. Even some modular instruments are equipped with OTDR/OCID testing, Ethernet testing, spectrum analysis, antenna feeder standing wave ratio analysis and other functions, which can provide a full range of communication technology connection and service testing functions,allowing operators to gain insight into all possible causes of transmission link failures.
As a key tool in digital communication systems, digital transmission analyzers can comprehensively improve the transmission quality of digital communication signals through their multiple functions and high-precision measurement capabilities. Whether it is the reduction of bit error rate, the optimization of jitter, or the improvement of signal integrity, digital transmission analyzers have played an irreplaceable role. With the continuous development of digital communication technology, digital transmission analyzers will continue to innovate and evolve, providing more powerful and accurate technical support for maintaining and improving the transmission quality of digital signals.
In response to the need to improve the transmission quality of digital communication signals, TFN has developed and designed a platform modular transmission analyzer to meet a series of network and transmission testing needs of operators.
