Information
Currently, China Mobile PTN has started large-scale deployment, in base station business hosting at the same time, also tried to use the RF coaxial connector IEEE1588 replace GPS time synchronization. Compare with GPS timing mechanisms, IEEE1588 in network security, cost control, network operation and maintenance have a distinct advantage.
IEEE1588 also saved some shortcomings, such as problems of asymmetric optical path, which brings to time transfer errors, thereby resulting in decreased time synchronization accuracy, time and frequency synchronization accuracy of reduction in network QoS indicators cannot be guaranteed, such errors need to be measured and to compensate. Therefore, only its time-frequency testing to ensure the normal operation of the system as a whole.
Time and frequency synchronization testing demands higher skills, this area has long been Europe, America and Japan controls by manufacturers, domestic enterprises do not have companies involved in this test.
