Problems solved by technology

[0007] At present, the broadband network test instruments and OPM test instruments used for FTTX testing in the market are designed for their respective modes. Some broadband network test instruments can only test the functions of the broadband network layer, and cannot support the OPM test; and The OPM test instrument can only test the parameters of the OPM optical network, and does not support broadband network testing
However, with the development of the telecom market in recent years, operators have both a large number of broadband IP users and many OPM users. The maintenance and support for these users is still completed by the same department. The single-purpose testing of existing equipment functions brings Therefore, there is a great need for a FTTX network maintenance terminal with DSL network terminal, Ethernet broadband network test and OPM test at the same time
[0008] On the other hand, the current test instruments can only perform on-site tests, and cannot support the operator's electronic work orders and wireless service tests. The test work of communication maintenance personnel is limited by the location, so test devices that support wireless communication functions have become urgent. need
