Embodiment
Below preferred embodiment of the present utility model is described in detail.
Shunt splice tray device 200 of the present utility model, as shown in Figures 2 and 3, it is connected between optical fiber and each terminal device, has replaced cabinet-type block 120 shown in Figure 1, wavelength division multiplexer 130 and power divider 140, can be used for realizing wavelength-division multiplex and power division.
The utility model shunt splice tray device is arranged on the base 210, and installs in a shell, not shown this shell mechanism; This base 210 is provided with an optical fiber distributing dish 220, between described base 210 and described optical fiber distributing dish 220, be provided with back up pad 230, and on this back up pad, being horizontally arranged with a plurality of carriages 231, this carriage 231 can be used to support and fix the coupling mechanism integration module 300 of a plurality of integrated wavelength-division multiplex systems and power distribution system.
Core point of the present utility model promptly in the splice tray of prior art, increases carriage structure is set, so that fixing a plurality of coupling mechanism integration modules 300.The utility model shunt splice tray device can be analogous to the splice tray of prior art, is connected the optical fiber end of registering one's residence, and its volume can narrow down to below 1/10th of prior art equipment, has greatly improved the effective rate of utilization and the practicality of device.
In the shunt splice tray device described in the utility model, on described base 210, also be provided with an optical cable securing member 240, be used for the cable of fastening output.And on described carriage 231, also be provided with bundling belt 232, be used for described coupling mechanism integration module 300 is fixed on described carriage 231.
Sky related in the utility model shunt splice tray device increased in the splice tray of high strength insulation crust, and be that described coupling mechanism integration module is installed in its inside by carriage with the mini composite type wavelength division multiplexer and the power splitter of unique design, to reach perfect combination.
When in constructions such as network layings, only need the optical fiber end of outside is connected the signal input part of the utility model shunt splice tray device, just can obtain 96 or 144 signals at output terminal through ovennodulation, can export to the terminal user and directly use, greatly shorten the time of network design and installation.
And since the utility model shunt splice tray device to take volume little, can expand the distribution that optical fiber is registered one's residence as much as possible, and can be because of volume excessive and seriously taking of resource and influence the expansion of terminal client.
Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion, and all these improvement and conversion all should belong to the protection domain of the utility model claims.
