Problems solved by technology
[0009] There are many defects in the existing similar technology. The traditional PON optical power meter has three test and calibration wavelengths, namely 1310nm, 1490nm and 1550nm, which can measure the real-time optical power of 1G EPON and GPON optical networks online. However, the test wavelength cannot cover 10G EPON And GPON optical network, can not meet the upgrade test requirements of optical network in the future

Description
technical field [0001] The invention relates to 1G / 10G EPON and GPON optical network power measurement technology, in particular to a comprehensive power testing device suitable for 1G and 10G PON network testing. Background technique [0002] With the rapid development of my country's economy, high-bandwidth consumption services are gradually emerging, and bandwidth speed-up has become an urgent need. Both switching and transmission have been updated. The slow development due to many reasons, such as the user's economic affordability, has become a bottleneck restricting the development of the network to broadband and full service. In order to meet the needs of users, various new technologies are constantly emerging, and access network technology has become the focus of attention and investment of equipment manufacturers, operators and telecommunications research departments. [0003] Passive Optical Network (PON) is a pure media network, which avoids the electromagnetic int...
