Description
- This application claims priority to U.S. Provisional Patent Application No. 60/424,534 filed Nov. 7, 2002.
- The present invention relates to a cleaning device useful for cleaning the optical fibers in a connector. In particular, the present invention relates to a hand-held device suitable for cleaning the optical fibers that have been mounted in a ferrule.
- Optical fibers have become useful for transmitting information such as data and voice communication. For similar sized cables, the advantage of optical fiber cables over traditional wire cables lies in the fibers' improved transmission rate and in the increased capacity to transmit information.
- Optical fibers are often terminated and coupled to other optical fibers or to other terminals through the use of connectors. In some optical connectors, ferrules are used. The ferrule typically has a plurality of fiber receiving channels where the optical fibers are mounted. When two connectors are used to connect two optical cables, a first connector typically contains a ferrule that has at least one guide pin extending from its end face. A second connector contains a mating ferrule that has at least one guide pin hole on its end face. In this particular design, alignment and mating of the two connectors occurs when the guide pin is inserted in the guide pin hole. The optical fibers in mating connectors should have intimate contact in order to minimize light transmission loss between them. Thus, it is desirable that the mating end faces of the ferrules be free of lint, dirt, oil, and other debris. It is known in the art to clean the ferrule end faces to minimize light transmission loss by minimizing the dirt.
- For example U.S. Pat. No. 6,449,795 B1 (Sato) discloses a cleaning tool for optical fiber connectors comprising a bar form stem, a support, the outside of which is covered with a cleaning cloth made of ultra fine filament bundle having a filament fiber size of 0.1 denier or less. The stem and the support are made integrally from resin.
- U.S. Pat. No. 6,415,471 B1 (Childers et al.) discloses another device for cleaning the polished end faces of fibers in an optical connector having guide pins. The device has a surface with at least one rail disposed on the surface. The rail has a height above the surface sufficient to accommodate guide pins extending from an optical connector. An overlay is disposed over the surface of the device and functions as the cleaning cloth.
- U.S. Pat. No. 5,220,703 (Kanayama et al.) discloses yet another optical connector cleaner. The cleaner comprises (i) a cleaning cloth woven with ultrafine fiber less than 0.1 denier, (ii) a casing formed with at least one opening for protecting the cleaning cloth from dust, and (iii) a mechanism for shifting the cleaning cloth exposed in the opening for renewing the cloth after ferrule end surface has been cleaned.
- Although the foregoing references may provide useful connector cleaning devices, there is a need for other easy to use devices.
- The present invention provides a unique device useful for cleaning fiber optic connectors. Although the device is particularly suited to clean the polished end faces of a ferrule that has optical fibers mounted therein and to clean the mating surfaces of connectors, it can also be used to clean other surfaces of the connector. The device is designed to easily accommodate the polished end faces of a ferrule that contains no guide pins or at least one guide pin.
- In brief summary, the present invention pertains to a device for cleaning a polished end-face of an optical connector, the device comprising (a) a three-dimensional base having at least three sides, the base having a polygonal cross-section (b) a cleaning media disposed on at least a portion of at least one side of the base; and (c) means for fastening the cleaning media to the base.
- The invention is further described with reference to the following drawings, wherein:
- FIG. 1 is a cross-sectional view of one embodiment in accordance with the present invention;
- FIG. 2 is a cross-sectional view of another embodiment in accordance with the present invention;
- FIGS. 3a and 3 b are isometric views of another embodiment in accordance with the present invention in the unfastened and fastened conditions respectively;
- FIGS. 4a and 4 b are, respectively, side view and isometric view of a means for fastening that can be used in accordance with the present invention;
- FIG. 5 is a isometric view of another embodiment in accordance with the present invention using the means for fastening shown in FIGS. 4a and 4 b; and
- FIG. 6 is an isometric view of a connector.
- These figures are idealized, not drawn to scale, and are intended to be illustrative and non-limiting.
- FIG. 1 is a cross-sectional view of one embodiment of the present invention wherein
device 1 has acleaning media 12 disposed on at least a portion of three-dimensional base 10. In this particular embodiment, in cross-section view, the base is a truncated triangle having a substantiallyflat peak 10 a andsides cleaning media 12 topolygonal base 10 is the roughened surface (not shown) ofsides cleaning media 12 is shown to be disposed onsides side 10 a would be a true peak. Thus, the base has a minimum of three sides. In use, an operator can clean the polished end surface of the connector using the cleaning media at the general area designated atpeak 10 a. The operator can advance new cleaning media to thepeak 10 a by removing it from the base and repositioning it on to the base. - FIG. 2 is a cross-sectional view of another embodiment of the present invention wherein
device 2 uses means for fastening 14 to fastencleaning media 12 to at least a portion ofbase 10. In this particular embodiment, the means for fastening is a tape, e.g., a microreplicated tape having an adhesive backing that can be laminated tosides cleaning media 12 so as to secure it. The tape allows for repositioning of the cleaning media so that new cleaning media could be advanced to the peak area once it has been used. - FIGS. 3a and 3 b illustrate yet another embodiment of the present invention in the unfastened and fastened conditions respectively. In this particular embodiment, the means for fastening cleaning
media 12 topolygonal base 10 isframe 16 having an opening 16 a. In use,frame 16 is disposed near the peak area ofbase 10 holding the cleaning media to the base while opening 16 a exposes a portion of the cleaning media for cleaning the optical connector. If desired, means for fastening 14 (shown in FIG. 2) or roughenedsides frame 16. - FIGS. 4a and 4 b show yet another means for fastening the cleaning media to the polygonal base. Means for fastening 18 is a cover with opening 18 a and
optional finger tab 18 b. In this embodiment, means for fastening 18 is substantially triangular in cross-section, similar in shape to the cross-section ofbase 10. FIG. 5 shows yet anotherdevice 5 having cleaningmedia 12 sandwiched between means for fastening 18 andbase 10 with opening 18 a disposed near the peak of the base thereby exposing a portion of the cleaning media for cleaning the optical connector.Hemispherical finger tab 18 b allows for easy removal of means for fastening 18, as a user can push upwards on the tab and remove it. One skilled in the art will recognize that a hemispherical finger tab is one of many possible designs that can be used. The means for fastening 18 has aportion 18 c that function to protect at least a portion of the underlying cleaning media from contamination of dirt. In use, while thedevice 5 is held in the operator's hands, it is theportion 18 c that is in contact with the hands. Any oil from the operator's skin, one of the more common sources of contamination, will not transfer to the cleaning media. Thus the cover provides advantages in that it protects the cleaning media, contains an opening for easy access to the cleaning media and simultaneously secures it to the base. While FIG. 5 shows a means for fastening 18 that is in a form of an open cover, it is within the scope of the invention that the means for fastening is closed such that it slips over thepolygonal base 10 and cleaningmedia 12. For example, in FIG. 5, the means for fastening 18 can have up to three cut outportions 18 a, each disposed over one of the angles of the base. In this case, thefinger tabs 18 b would most likely not be used. - FIG. 6 shows a terminated
connector 400 comprising ahousing 410, apolished ferrule 420 and guide pin holes 422. Theoptical fibers 421 have been mounted in the ferrules. While not shown, in use, there would be a mating connector similar to that shown in FIG. 6 except that where there are guide pin holes, there would be guide pins. When theconnector 400 comes into contact with its mating connector, the guide pins reside in the guide pin holes. Prior to mating, it would be desirable to clean the end faces of theconnector 400 as well as the mating connector. Because the mating connector contains guide pins, it can be difficult to clean in the area of the mounted optical fibers, i.e., the area between the guide pins. The present device allows for cleaning the polished end faces of the ferrules, whether they contain guide pins or not. - The three-dimensional base can be made of any material, so long as it does not introduce contaminants during use. Thus, materials that flake or chip easily are not suitable. The base should be sturdy, i.e., firm enough so that during use it will not move. Useful materials for the base include metals, polymers, ceramics, and wood. Suitable polymeric materials include those containing acetal homopolymers and copolymers (such as CELCON™ from Hoechst Celanese Co. and DELRIN™ from Du Pont Co.), nylon, polycarbonate, rigid polyvinyl chloride (PVC), and ABS (acetylene-butadiene-styrene). The base can be made by any number of methods depending on the material used. For example, when the base is polymeric, it can be injection molded.
- As stated, in a cross-sectional view, the three-dimensional base is polygonal. The cross-sectional view can be taken either parallel or perpendicular to the bottom of the base, as represented, for example, by
side 10 d in FIG. 1. Although a truncated triangle is one useful cross-section, one skilled in the art will recognize that a number of other polygons can be used as long as at least one of the angles is less than about 30°. For example, the base can have a star shaped cross-section in which case, all five angles can be used to clean the connector. There can be five separate means for fastening for each of the five angles or one continuous means for fastening, e.g., one continuous cover, to slip over the base. Wedges and rhomboids are other useful three-dimensional bases. The three dimensional base, however, does not contain a rail. If desired, the base can be modified to include cut outs or notches. For example, in FIG. 3a, in another embodiment, the base 10 contains cut outs on the peak area (i.e., near 10 a, not shown) front and rear portion thereof. This particular embodiment is useful in that it clearly delineates to a user where the cleaning media should be placed. - Referring to FIG. 1, one embodiment of a base has the following dimensions. The
sides side 10 d to peak 10 a) is about 2.0 inches (50.8 mm). Theflat peak 10 a is about 0.035 to 0.045 inch (0.89 to 1.14 mm) with the angle α being about 30°. - In one embodiment, as described above in FIG. 1, the surfaces of at least one of the sides of the base can be modified, e.g., they can be roughened. When the base is a polymeric material, the sides can be surface roughened by sand blasting. In particular, when the base is CELCON™, one can roughen the side surfaces by bead blasting using a Dayton Co. from Dayton, Ohio model #3Z850 with a silicone carbide media at an air pressure of about 50 psi.
- The cleaning media can be a swatch that covers a portion of the base or it can encircle the entire base. Suitable cleaning media includes products, such as (i) TexWipe® TX304, 100% cotton wipes, and Absorbond® TX404, hydroentangled polyester wipes from The TexWipe Co., Upper Saddle, N.J. and at the website www.texwipe.com; (ii) the non-woven cloth from the Fiberclean dispenser System, Part No. FOI, from the HellermannTyton, Milwaukee, Wis. and at the website www.hellermann.tyton.com; (iii) the micro fiber cleaning cloth from the OPTIPOP reel cleaner from NTT Advanced Technology Co. in Tokyo, Japan, and (iv) polyester wipes from the Tech Spray Co. in Texas. Other types of polymeric cleaning media, such as nylon, polyethylene, and polypropylene can be used.
- As disclosed in the various embodiments above, the means for fastening the cleaning media to the base can be selected from the group consisting of surface roughening the sides of the base, adhesives, frames, covers, and the like. Combinations of these means can be used. When the means for fastening are a frame or a cover, it can be made from a wide selection of materials, such as metals, polymers, and ceramics. Suitable polymers include polycarbonates, nylon, ABS, and rigid PVC. Each of the above recited means allow for repositioning of the cleaning media. If desired, the means for fastening can also be made static or electrostatic dissipative.
