Abstract
The utility model discloses a plug-in film-plated optical reflector comprising two ceramic cores and a connection sleeve. The butting ends of the two ceramic cores are inserted into the connection sleeve. A WDM optical filter is arranged in the connection sleeve and between the two ceramic cores. The WDM optical filter is pasted in the two ceramic cores by adhesive and on the end face of the butting end of one ceramic core. The thickness of the WDM optical filter is 30 [mu]m. Since the above structural style is used, a problem of high cost caused by directly plating the core end face with a film is prevented by directly pasting the plated WDM optical filter 30 [mu]m thick on the core end face.
Description
Technical field
The utility model relates to fiber optic network monitoring equipment, particularly
a kind ofplug-in pad pasting optical reflector.
Background technology
FTTH is large-scale to be laid and application, the enormous amount of optical fiber link, and topological structure is complicated, become very important of the management of fiber optic network and malfunction monitoring.A kind of novel fiber network monitoring system has started small-scale application, this fiber network monitoring system is comprised of OTDR (optical time domain reflection equipment) and a lot of optical reflector, between equipment and reverberator, there are the optical device links such as photoswitch and passive WDM. optical reflector is the Primary Component in fiber network monitoring system, it has multiple packing forms, and Hermaphrodite fixed attenuator packing forms is the packing forms of the main use of optical reflector.
Plug-in packing forms optical reflector consists of two parts, and the one, ceramic insertion core chipware, the 2nd, chipware is packaged into the loose mail of finished product, the effect of loose mail is to provide the interface shape mating with optical patchcord.Chipware is comprised of three parts, the ceramic insertion core that two segment length are identical, WDM functional membrane, a metalwork with bayonet socket.WDM functional membrane is directly coated on insertion core end face by the method for plated film.Two sections of lock pins are by being assemblied in metalwork, the plated film end face of lock pin and the end face close contact of other one section of lock pin, and surface of contact is inner at metalwork.Fixed form between metalwork and lock pin, can be to stick with glue knot, also can be crimped on together by friction tight mode.After chipware assembling, carry out again the grinding of outside 8 degree angles.After chipware assembling, carry out the assembling of chipware and outside loose mail.The effect of outside loose mail is to form plug-in optical interface, is connected with outside wire jumper.In this structure, the optical fiber in ceramic insertion core is used for transmitting optical signal, and the WDM function film of insertion core end face carries out filtering to the light signal signal passing through, and service wavelength is all seen through, to supervisory wavelength total reflection.
The mode that this lock pin is coated with WDM optical filter can realize device function, but has some problems in extensive manufacturing process.Because WDM function film is the film producing process that a kind of precision is very high, in the process being coated with, there is certain yield, plated film on lock pin, the yield of WDM film can cause lock pin to have certain loss, and the bad lock pin of plated film need to do over again or scrap, and the unsuccessful meeting of this plated film directly causes lock pin plated film mode high expensive, in addition, the coating machine useful space is certain, and single lock pin area occupied is larger, and corresponding cost is higher.The unit lock pin area of lock pin plated film mode is very large, and seldom, this factor also causes lock pin plated film mode to realize high expensive to the quantity of a plated film.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, and the plug-in pad pasting optical reflector that a kind of cost is low is provided.
For achieving the above object, the technical scheme that the utility model adopts is:
Plug-in pad pasting optical reflector, comprises two sections of ceramic insertion cores and joint sleeve, and the butt end of described two sections of ceramic insertion cores is inserted in joint sleeve, in described joint sleeve and be provided with WDM optical filter between two sections of ceramic insertion cores.
Described WDM optical filter by glue in two sections of ceramic insertion cores, on the end face of the butt end of one of them ceramic insertion core.
The thickness of described WDM optical filter is 30um.
Described joint sleeve is bonding by glue and two sections of ceramic insertion cores.
One end of described joint sleeve is connected with installation fixed cover, and ceramic insertion core passes and be bonding with installation fixed cover by glue from fixed cover is installed.
The beneficial effects of the utility model: owing to adopting above-mentioned version, the present invention uses the WDM optical filter of coated 30um thickness, is directly attached to insertion core end face, the high problem of cost of effectively avoiding the direct plated film of insertion core end face to bring.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
In figure: 1, ceramic insertion core; 2, ceramic insertion core; 3, joint sleeve; 4, WDM optical filter; 5, fixed cover is installed.
Embodiment
As shown in Figure 1, plug-in pad pasting optical reflector, comprise ceramic insertion core 1, ceramic insertion core 2 and joint sleeve 3, the butt end of described ceramic insertion core 1 and ceramic insertion core 2 is inserted in joint sleeve 3, and described joint sleeve 3 is interior and be provided with WDM optical filter 4 between ceramic insertion core 1 and ceramic insertion core 2.The thickness of described WDM optical filter 4 is 30um.Described WDM optical filter 4 by glue on the end face of the butt end of ceramic insertion core 1 or ceramic insertion core 2.
Described joint sleeve 3 is bonding by glue and ceramic insertion core 1 and ceramic insertion core 2.One end of described joint sleeve 3 is connected with installs fixed cover 5, and ceramic insertion core 2 passes and be bonding with installation fixed cover 5 by glue from fixed cover 5 is installed.
Principle of work: this patent relates to a kind of reverberator implementation, adopt ultra-thin WDM optical filter technology, in ferrule endface, mount a very thin WDM filter coating, also referred to as WDM optical filter, the thickness of this WDM optical filter is in 30um left and right, very thin thickness due to WDM film, directly be attached on insertion core end face the same with the effect of direct plated film on insertion core end face, ultra-thin WDM film is used the coating process of standard, can be coated with sheet is on glass, after being coated with, test, after test passes, be mounted on again in ferrule endface, can effectively avoid the problem of the bad high expensive causing of the direct plated film of insertion core end face, secondly, very little for the fiber optic aperture of logical light in ceramic insertion core, size is 125um, the size of WDM optical filter is only greater than this size and just meets the demands, the quantity that one stove is coated with WDM optical filter is a lot, more than the quantity of ceramic insertion core plated film, also can greatly reduce the cost of the WDM of unit optical filter far away.
The above is preferred implementation of the present utility model; certainly can not limit with this interest field of the utility model; should be understood that; for those skilled in the art; the technical solution of the utility model is modified or is equal to replacement, do not depart from the protection domain of technical solutions of the utility model.
