And reflection end, the light-baffling device 104 include optical fiber collimator and light barrier.In this, the wavelength division multiplex device 103 and it is in the light
Device 104 is installed in cross-connecting box, and transmitter unit 101, wave multiplexer 102, channel-splitting filter 105 and receiving unit 106 are installed on local side,
Save space and not electricity consumption in cross-connecting box.
In the present embodiment, cross-connecting box is multiple and series connection, and each cross-connecting box corresponds to the different wave length that transmitter unit is sent
Light.One or more inside doors are included in each cross-connecting box, and the multiple inside door connects for series system.Specifically, each
Include a pair of wavelength division multiplex devices and N number of light-baffling device in cross-connecting box, N for each cross-connecting box inside door quantity, it is described N number of to be in the light
Device is one another in series.
It is assumed that transmitter unit has 4 lasers, centre wavelength is λ 1, λ 2, λ 3 and λ 4 respectively.Then used in each cross-connecting box
Wavelength division multiplex device corresponding to centre wavelength be respectively λ 1, λ 2, λ 3 and λ 4.Wave multiplexer and channel-splitting filter only have 1 respectively, respectively
It is respectively that λ 1, λ 2, λ 3 and λ 4 wavelength division multiplex device is formed by 4 centre wavelengths to be.Thus, the centre wavelength of transmitter unit
Centre wavelength with wave multiplexer, wavelength division multiplex device and channel-splitting filter is consistent.
Reference picture 2, the realization principle of gate inhibition's monitoring are as follows：1~λ of λ 4 light passes through the 1st wavelength division multiplex device 103 (i.e.
WDM after), the light that wavelength is λ 1 is filtered out and (come out from transmission end), but 2~λ of light λ 4 of remaining wavelength are from reflection end
Out.These light come out from reflection end will come in from same WDM reflection end, and be bonded to output port output.So
The light-baffling device 104 of series connection is passed sequentially through afterwards.Each light-baffling device includes a pair of optical fiber collimators, and the optical fiber collimator is C-
Lens, G-lens or optical fiber head.Can be from light path by when light barrier is displaced downwardly to light path, that is, realizing in normal condition light
Light path is obstructed.Specific embodiment described in the present embodiment is as follows：4 cross-connecting boxes are marked by different wavelength (1~λ of λ 4) respectively
Know.All it is to close if all of inside door, this 4 wavelength can be detected in monitoring side.Some if (or multiple) hand over
The inside door for connecing case is opened, then that corresponding wavelength (or multiple wavelength) can not be detected, and principle is come real according to this
Now monitor.By taking the 1st cross-connecting box (it is assumed that each cross-connecting box has four inside doors) as an example, when four inside doors are all in "Off" state
When, wavelength is that λ 1 light can be detected in monitoring side；When any one in four inside doors or multiple inside doors are in " beat
Open " state when, the light that wavelength is λ 1 will be blocked (reflection, absorb or scattering) by light barrier, it is impossible to pass through.Now wavelength is λ 1
Light can not be detected in monitoring side.
Fiber cable cross connection box gate inhibition's monitoring method flow chart that Fig. 3 present pre-ferred embodiments provide.As shown in figure 3, this hair
