光纤通信由于具有通信容量大、传送信息质量高、传输距离远、性能稳定、防干扰、抗腐蚀能力强等优点,而得到了人们的青睐。特别在近几年来,随着人们对带宽业务的不断需求和光纤成本的不断降低,光纤通信得到了大力的发展,其应用已涵盖从骨干网、城域网到接入网,甚至深入到用户驻地网等各个领域。光通信技术的发展,在使光纤传输信息的能力越来越大的同时,也使人们对光通信网络的依赖越来越强,这也意味着任何的网络故障甚至哪怕是性能下降都会造成更大的损失。如何才能保持光网络的正常运转、提高运行效率,打造一个具有高性能、高可靠性、高可用性的“精品”网络,成为运营商面临的主要挑战,这也为通信测试厂商带来了难得的市场机遇。面对日益复杂的网络环境和运营商对降低运维成本、提高服务质量的迫切需求,测试厂商不约而同地把提供一个集成多种测试功能、可以灵活适应网络变化和发展需要的综合测试平台作为自己的主攻方向,先后推出了具有各自特色的模块化的综合测试平台产品。衡量新一代模块化测试平台的主要标准包括:满足不同测试需要的测试模块的功能和数量,是否具有高度自动化的测试方法和软件,是否具有灵活的体系结构以适应通信技术和标准的未来变化以保护用户的投资等。本刊选择了当前市场上三款主?
Optical fiber communication has been favored by its advantages such as large communication capacity, high transmission information quality, long transmission distance, stable performance, anti-interference and anti-corrosion ability. Especially in recent years, with the constant demand for bandwidth services and the ever-decreasing cost of optical fibers, optical fiber communication has been greatly developed. Its applications have ranged from backbone networks, metropolitan area networks to access networks and even to users Resident Network and other fields. The development of optical communication technology, while making the ability of optical fiber to transmit information more and more large, make people rely more and more on the optical communication network at the same time, this also means that any network trouble even even the performance drop will cause more Big loss. How to keep the normal operation of the optical network and improve the operation efficiency and create a “boutique” network with high performance, high reliability and high availability has become a major challenge for operators, which also brings a rare Market opportunity. Faced with the increasingly complex network environment and the urgent need of operators to reduce O & M costs and improve service quality, test vendors invariably provide themselves with a comprehensive test platform that integrates various testing functions and can flexibly adapt to the needs of network changes and development The main direction, has introduced its own characteristics modular integrated test platform products. The key criteria for measuring the new generation of modular test platforms include the ability and number of test modules to meet different test needs, the availability of highly automated test methods and software, and the flexibility to adapt to future changes in communications technologies and standards Protect user’s investment and so on.
