光纤接续采用熔接法,连接可靠、损耗小,是使用最为普遍的一种方法。采用“双向对测法”进行测试,可以大大减小测量误差。施工时要严格按施工工艺流程操作,尽量避免在潮湿天气、沙尘天气等恶劣的气象条件下操作,最大限度地减少整条OPGW线路的衰耗,以提高通讯质量。 Splicing optical fiber by welding, reliable connection, low loss, is the most common use of a method. Using the “two-way on the test” for testing, can greatly reduce the measurement error. Construction should be strictly in accordance with the construction process operation, as far as possible in wet weather, dust weather and other harsh weather conditions to minimize the attenuation of the entire OPGW line to improve communication quality.
