Definitions
- This invention relates generally to a fusion element and more particularly to an element for use in splicing optical fibers.
- a fusion splice element that forms an enclosure over fused optical fibers housed within.
- Such a fusion element would provide a relatively clean fusion cavity in which fusion may take place.
- the fibers need not be inserted into a guide hole where debris could come into contact with the end of the fiber, thus causing degradation of the fusion joint.
- the fibers instead can be placed into an alignment groove and remain clean.
- the splice element is closed upon the fused optical fibers and remains with the spliced fused fibers providing a rigid support and strain relief for the fusion joint within.
- the fused fibers within the splice element remain in a clean protective environment.
- fusion may take place within a closed fusion element after a base portion and lid are sealed close.
- an optical fiber splice element comprising a base member having a fusion element for housing optical fibers for fusion within; and, a covering member for covering and forming an enclosure with the base member in a closed portion, at least one of the covering member and the base member having means for preserving closure in a closed position, the optical fiber enclosure in an open position having a channel at either end for accommodating one or more optical fibers.
- Fig. l is an oblique view of a splice sleeve having a built-in ceramic fusion block
- Fig. 2 is a top view of the splice sleeve in Fig. 1 including an optical fiber inserted in one end;
- Fig. 3 is an oblique view of the base portion of an alternative embodiment of a splice sleeve
- Fig. 4 is an oblique view of a splice sleeve having a separate base and lid
- Figs. 5a and 5b are oblique views of splice sleeves each having hinged lids with multiple sections.
- an optical fiber splicing element is shown in the form of a "butterfly" splice sleeve 10.
- a base portion 12 of the sleeve 10 is hingedly connected to a covering member in the form of a lid 14.
- a fusion member shown as a ceramic block 20 is located centrally within the base portion 12 of the sleeve 10.
- Two conductive copper tracks 24 are each electrically connected by a copper plated barrel of a through hole 26 to a conducting pad (not shown) on the underside of the ceramic block 20.
- the copper tracks 24 can be bonded to the ceramic block 20 by being printed, glued, or plated thereon.
- the end 25 of each copper track 24 forms an electrode.
- a V-groove is provided in the splicing element for guiding the optical fiber in an alignment groove 28 in the ceramic block 20.
- holding means shown as protrusions 16 in the lid abut and hold optical fibers securely within the groove 22.
- the protrusions 16 are somewhat compliant and preferably resilient so that they form around the fibers and tightly squeeze the fibers without damaging them, yet at the same time, provide clamping upon the fibers serving as a strain relief for a fusion joint within the sleeve 10.
- An outer lip 30 on the lid 14 provides a means of securing the lid in a closed position as it engages the underside of the lip 32 on the base portion 12 of the sleeve 10.
- two optical fibers are placed into the base portion so that their ends hang over the opening 33 in the ceramic block 20.
- one optical fiber 37 is shown inserted.
- a sufficiently large voltage is applied across the conducting pads (not shown) to generate an electric arc across the tips of electrodes 25 so, as to melt and fuse the ends of the fibers together.
- the lid 14 is then closed to secure and retain the fused fibers within the splicing element 10.
- the fibers could be placed into the base portion 12, ready for fusion with the lid 14 being closed to retain the fibers. An electric arc could then be generated across the electrode tips to cause the fiber ends to fuse together.
- a base member 40 includes an optical fiber channel guide on each side of a passline 44 indicated by a dotted line.
- the passline 44 defines an access path for external electrodes for fusing optical fibers supported by the base member 40.
- a ceramic alignment block 46 is provided for supporting unclad portions of the optical fiber ends that are to be fused.
- a splice sleeve having a base member 50 and seperate lid 54.
- the base member 50 contains a ceramic block 54 for supporting optical fibers that are to be fused. After fusion takes place the lid 54 is secured to the base member 50 covering and protecting fused fibers within.
- Figs. 5a and 5b show alternative hinged lid arrangements.
- a sealed port 60 is shown in the central fusion portion of the sleeve for viewing of the fusion cavity within.
- Fig. 5b a sleeve is shown having a base 70 that includes two lids 72 hinged at the ends of the base 70.
- numerous other embodiments may be envisaged, without departing from the spirit and scope of the invention.
