Abstract

The utility model discloses an optical time domain reflectometer with a wireless communication function. The optical time domain reflectometer comprises an intelligent control module, a pulse generation module, a coupling module and a pulse detection module. The optical time domain reflectometer further comprises a wireless communication module and a GPS module respectively connected with the intelligent control module (1). The optical time domain reflectometer can make on-site testing related with remote offices. Wireless signal testing of instrument locations can be achieved by means of the wireless module coupled with the GPS position information. The testing work contents of communication maintainers are more comprehensive. The handling of business such as electronic work order replying is more timely and not restricted by locations. The office efficiency is thus increased.

Description

The optical time domain reflectometer that has radio communication function

Technical field

The utility model belongs to communication network maintenance technology field, particularly a kind of optical time domain reflecting device.

Background technology

The global communication industry develop the rapid growth that has driven global communications market rapidly, the expansion of Communications Market makes the user constantly strengthen the degree of dependence of communication network, how to improve the communication network running quality and has become global focal issue.No matter be to research and develop the communications equipment manufacturer of forefront to being in the network communications technology, still building and safeguarding the operator of same advanced person's communication network, it is most important that network testing instrument and network management and operation maintenance system seem undoubtedly.Therefore, provide integrated, multi-functional, many technology, multi-level complete testing apparatus to become the common recognition in global communication test maintaining field.

Optical time domain reflectometer (OTDR, Optical Timedomain Reflectometer), it is topmost instrument in the optical fiber measurement, be widely used in measurement, construction, maintenance and the checking and accepting of optical fiber cable engineering, be the highest field instrumentation of usage frequency in the fibre system, being it is called of image is " universal instrument " in the optical communication.But present OTDR can only carry out on-the-spot test, can't support the test of electronic work order and the wireless traffic of operator, cause communication attendant's test job to be subjected to the phenomenon of site limitation, therefore, be badly in need of content measurement comprehensively, support the optical time domain reflectometer of wireless traffic.

The utility model content

The purpose of this utility model provides a kind of optical time domain reflectometer that has radio communication function.

Realize that method of the present utility model is: a kind of optical time domain reflectometer that has radio communication function, comprise intelligent control module, pulse generation module, coupling module, pulse detection module, also comprise wireless communication module and GPS (Global Positioning System, be global positioning system) module, and wireless communication module is connected respectively at intelligent control module with module.

Described pulse generation module comprises: pulse generator, laser module and selection amplification module.

Described pulse detection module comprises: Photoelectric Detection module, amplification module and analog-to-digital conversion module.

Described intelligent control module comprises the CPU(central processing unit) module and FPGA(Field-Programmable Gate Array, i.e. field programmable gate array) module.

Described wireless communication module comprises: the blueteeth(bluetooth) module and WLAN(Wireless Local Area Networks, i.e. WLAN (wireless local area network)) module.

The beneficial effects of the utility model are:

1, set up wireless communication module, on-the-spot test and telecommuting can be linked together, improve office efficiency, can acceptance test task in real time and reply test result, make work more timely, more accurate.

2) in wireless traffic is measured, can finish the wireless signal measurement of instrument loca by wireless module in conjunction with the GPS positional information, make communication attendant's test job content more comprehensively, handle business such as replying electronic work order and more in time and not be subjected to the restriction in place.
