The optical module cloud test system of the present invention is by being arranged at high in the clouds by test equipment, and is controlled by cloud server
The local test station processed access to test equipment so that optical module testing efficiency uprises；And this layout of the present invention can root
Border test needs to increase and decrease arbitrarily equipment factually, and motility is good.
The light matrix of the present invention uses N × M photoswitch, is used for interconnecting test device and local test station so that from this
Each light path of testing station, ground can have access to any one test equipment, in a specific embodiment, can use
MEMS(Micro Electro-Mechanical System) etc. the photoswitch of type.
In one embodiment, described TRM includes the request of light path access port, test device request, test
Item request.
Local test stands in when testing, and needs to transmit optical signals in corresponding test device, owing to have employed
Light matrix, it is therefore desirable to cloud server removes to control the switch of light matrix, reasonable distribution completes test, and local test station is accomplished by
It is linked into which light mouth to cloud server request, from which light mouth goes out.
In one embodiment, described test device includes oscillograph, energy meter, attenuator, signal projector, error code
At least one in instrument, spectrogrph.
Certainly, test device is not limited to above-mentioned three kinds, and can increase according to actual needs and delete, such as when only needing
The when of luminous power to be tested, it is possible to all of test device is all replaced with energy meter to meet testing requirement, due to this
Scheme uses the technology that light matrix and high in the clouds control, and the most this replacement will not produce extra cost, and efficiency is the highest.
Oscillograph, also with CDR function, for therefrom recovering triggering signal, if oscillograph does not have CDR function, then needs
Increase a beam splitter and ce circuit, in order to from optical signal, recover Trigger, and it is defeated to be input to oscillographic Trigger
Enter end.
In one embodiment, so cloud server is additionally operable to control shutoff or the Guan Bi of optical matrix switch, institute is made
The optical signal stating local test station is sent in the test device that described cloud server is specified.
