Description
Technical field
The utility model relates to the auxiliary body of optical fiber wiring, relates in particular to the lane assignment mechanism of the passive Ethernet of a kind of light (EPON).
Background technology
(Ethernet Passive Optical Network EPON) by the standard (IEEE 802.3ah) of Institute of Electrical and Electric Engineers (IEEE), holds its low-cost advantage under the arm to passive type ether fiber optic network, and the main flow that becomes the optical-fiber network wiring is rapidly selected.EPON is not for needing any fiberoptical networking to multiple spot that optical device constituted of power supply.Technology with optical fibre wavelength division multiplexer (WDM) realizes the point-to-multipoint two-way communication, the ether host-host protocol is introduced the access networking, finish one from the end points to the multi-endpoint, networking, the broadband environment of single host-host protocol and avoid handling conversion between various different agreements promotes the overall efficiency at networking.A typical EPON system is made up of OLT, ONU and POS.Optowire terminal (OLT, Optical Line Terminal) centre machine room, optical network unit (ONU, Optical Network Unit) are placed near the network terminal interface unit or with it and are integrated.Passive fiber splitter (POS, Passive OpticalSplitter) is a passive component that connects OLT and ONU, and its function is: distribute descending data and concentrate up data.
When realizing the universalness of fiber-to-the-home (FTTH), need to rely on the simplification construction method and reach, and optical branching device wherein need possess following characteristic: fiduciary level is good: optical branching device is returned and is studied carefully its failure cause, often externally goes between.Outside lead is exposed outside, does not have the casing protection, simultaneously need be under various complex environments installation wiring.For guaranteeing the reliability of shunt, at first want the high optical fiber of dependability.Volume is little, in light weight: optical branching device generally is installed in remote places such as roadside electric pole, open-air frame.Volume is little and in light weightly just seem extremely important, very convenient to carry.Install fast: need external power source when the characteristics of passive type assembly are to install, and the optical splitter device is built when putting out of doors, instrument that need not be extra and technology need only be operated indication, and pigtail splice is just plugged and can be used.The optical branching device (Silica-based Planar Lightwave Circuit PLC optical splitters) that in existing planar optical waveguide splitter (PLC), adopts bend resistance optical fiber to make usually, connect a main fiber that constitutes by simple optical fiber (outside is provided with sheath) and one to four strand of branch optical fiber respectively by the multifiber set at each splitter two ends, per share branch optical fiber every optical fiber after passing a sheath fixed head all adds upper jacket, constitutes a band sheath branch optical fiber bundle.Band sheath branch optical fiber light beam is that the many optical fiber identical with the main fiber structure flock together.Splitter is arranged in the middle of the enclosed box body, and main fiber and band sheath branch optical fiber light beam pass from box body two respectively, and a plurality of this box bodys are integrated in the casing and promptly constitute shunt; Its shortcoming is that box body needs the two ends perforate, need take two ends into account when inserting casing, and easily break optical fiber, and be unfavorable for the casing sealing and detect maintenance after inserting casing.
Summary of the invention
The utility model is in order to solve the existing box body two ends perforate that splitter is set, and is not easy to the defective that patches and seal, provides a kind of shunt to take out dish, and it adopts monolateral open-celled structure, needn't take two ends into account when inserting casing, and have better closure.
For solving the problems of the technologies described above, the technical solution of the utility model is that a kind of 1 * 16 shunt of structure is taken out dish, the cover plate that it comprises a rectangular base plate and is connected base plate top.Base plate and cover plate constitute a semi-enclosed cavity, and base plate top one end also connects a strip side plate, and cover plate has an opening towards the side plate place, respectively are provided with a snap close at the side plate two ends, are provided with opening optic fibre hole and opening optical fiber beam hole on the side plate between two snap closes.
More excellent scheme, its length direction of described base plate upper edge is arranged with that be parallel to described side plate a pair of has the thread block of arc, the both sides of base plate are respectively equipped with the line ball pawl, also be provided with a line ball frame between thread block and the side plate, described cover plate covers thread block and line ball pawl and base plate and is combined into a semi-enclosed cavity.
The utility model is by having opening optic fibre hole and the opening optical fiber beam hole towards semi-enclosed cavity simultaneously on side plate, main fiber inserts, is with the branch optical fiber light beam of sheath to be punished out by side plate by the side plate place during use, and taps such as splitter partly are hidden in the semi-enclosed cavity.Hold the whole casing that inserts of side plate when patching, owing to adopt monolateral open-celled structure, closure is better, handled easily and maintenance; Side plate is provided with the convenient connection of snap close simultaneously, makes one-piece construction reliable.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 takes out the perspective view of disk chassis for the utility model shunt;
Fig. 2 is close perspective view behind the cover plate of Fig. 1;
Fig. 3 is arranged on the synoptic diagram that shunt is taken out the fiber section in the dish.
Embodiment
As shown in Figure 1 and Figure 2, for the utility model 1 * 16 shunt is taken out the dish structural drawing, the cover plate 4 that it comprises a rectangular base plate 2 and is connected base plate 2 tops, base plate 2 and cover plate 4 constitute a semi-enclosed cavity.Base plate 2 tops one end also connects a strip side plate 7, and cover plate 4 has an opening 6 towards the side plate place.Respectively be provided with a snap close 1 at side plate 7 two ends, be provided with opening optic fibre hole 5 and branch optical fiber beam hole 3 on the side plate 7 between two snap closes 1 successively.In the present embodiment, its length direction of described base plate 2 upper edges is arranged be parallel to side plate 7 a pair of, and to have the arcwall face of thread block 17, two thread blocks of arc relative.The both sides of base plate 2 its length directions of upper edge are respectively equipped with line ball pawl 16, also are provided with a line ball frame 15 between thread block 17 and the side plate 7.Cover plate 4 covers thread block 17 and line ball pawl 16 and is combined into a semi-enclosed cavity with base plate 2.
