Description
Technical Field
The utility model relates to an optical fiber communication field specifically is open-air type wavelength division multiplexing module of armor.
Background
The wavelength division multiplexing module sold in the current market can not meet the protection requirement of IP65 and can not meet the application requirement of an operator in the access market. With the further expansion of 4G LTE and the rise of 5G wireless networks, a centralized radio access network (C-RAN) will generate an increasing demand for a wavelength division multiplexing module that can be used in the field.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a can be applied to the field and wavelength division multiplexing module that the quality is reliable.
In order to achieve the above object, the present invention is realized as follows:
an armored field wavelength division multiplexing module comprises a waterproof packaging box, a passive wavelength division multiplexing module, an armored optical cable and a waterproof connecting socket. The waterproof packaging box comprises a box body, a box cover, a waterproof gasket and a sealing groove. The box main body is provided with an optical cable interface. The waterproof gasket is arranged at the joint of the box body and the box cover and plays a role in waterproof sealing. The seal groove is arranged on the side, close to the armored optical cable, in the box body, and plays roles in fixing and sealing the optical cable. The passive wavelength division multiplexing module consists of two groups of wavelength division multiplexing devices, and the number N of the wavelength division multiplexing devices in each group can be 6, 8, 12 or other. The wavelength division multiplexing devices are connected in series in a cascade mode. Each input port correspondingly inputs a group of wavelength signals, and each output port correspondingly outputs one wavelength signal. The armored optical cable is sequentially provided with an outer sheath, an armored hose, an inner sheath, Kevlar, a tight sleeve and an optical fiber from outside to inside along the radial direction. The armor hose plays the effect of protection optic fibre, waterproof bending of preventing. And a duplex fiber connector is arranged at the head end of the optical cable. The waterproof connecting socket comprises a duplex optical fiber adapter and a sealing cover. The waterproof connecting socket is used for connecting a far-end optical cable under the condition of ensuring waterproof sealing.
The armored field wavelength division multiplexing module for severe environment uses armored optical cables to realize wave combination or wave division of 6, 8 and 12 wavelengths. Its advantages are high water-proofing and bending-resisting performance, and wide temp range. The installation mode can be selected by an operator, such as hanging rods, hanging walls, cross connecting box installation and the like. The operator can maximize the utilization rate of original optical cable resources, save the laying cost of the optical cable, and realize the aims of intensification, green energy conservation, clouding and the like of the C-RAN.

Detailed Description
As shown in fig. 1, the waterproof packaging box includes a box body 101, a box cover, a waterproof gasket 102, and a sealing groove 103. The box cover is matched with the box body in size. The box body is provided with an optical cable interface 4. The waterproof gasket 102 is disposed at a joint of the box body 101 and the box cover to perform a waterproof sealing function.
The armored optical cable 3 is arranged on one side of the box, the tail end of the armored optical cable is connected with the output end of the passive wavelength division multiplexing module 2 in a fusion mode, and the head end of the armored optical cable is provided with a duplex optical fiber connector. The armored optical cable is sequentially provided with an outer sheath, an armored hose, an inner sheath, Kevlar, a tight sleeve and an optical fiber from outside to inside along the radial direction. The armor hose plays the effect of protection optic fibre, waterproof bending of preventing.
The sealing groove 103 is arranged in the box main body 101 close to the armored cable side, and the armored cable penetrates through the sealing groove along the horizontal direction. The space in the sealing groove 103 is used for filling waterproof glue to fix the armored cable and achieve the sealing effect.
As shown in fig. 2, the passive wavelength division multiplexing module comprises two sets of wavelength division multiplexing devices, and the number of the wavelength division multiplexing devices is 2N. The number of wavelength division multiplexing devices N per group may be 4, 6, 8 or others. The wavelength division multiplexing devices are connected in series in a cascade mode, namely the common end of each device is connected with the reflection end of the previous device. The passive wdm module 2 has input ports 201 and 202 respectively inputting a set of wavelength signals, and output ports 203, 204, and … … respectively outputting a wavelength signal.
The input port of the passive wavelength division multiplexing module 2 is connected with the waterproof connecting jack 4 through a pair of optical fiber connecting wires.
The output port of the passive wavelength division multiplexing module 2 is connected with the armored optical cable 3 by welding.
