Abstract

On circuit board 1, optical fibre 12 runs from laser 2 round bobbin halves 4A, 4B to connector 13. Screened box 5, board-mounted on pillars 6, 7, 8, covers the bobbin. Pillar 7 holds bobbin half 4A fixed, pillar 6 separates the halves and acts as a pivot, and pillar 8 engages slot 10 in pivotable half 4B. To tension slack in the fibre windings, half 4B is pivoted, and secured by screw 11. <IMAGE>

Description

OPTICAL FIBRE STORAGE APPARATUS The present invention relates to apparatus for storing optical fibre.
The invention is particularly applicable to the storing of a short length of optical fibre associated with modern 'pig-tailed' communications lasers.
Modern 'pig-tailed' lasers are typically a 14 pin dual-in-line device arranged to be mounted on a printed circuit board. The laser light emitted frond the laser enters a short length, e.g. up to 1 metre of optical fibre known as a pig-tail.
The storage of this fibre and its associated connector is critical in order to prevent damage to the fibre and/or the connector, and the following criteria must be met. The fibre bend radius must not be less than 40 mm, and the fibre, being fragile must not be bent or kinked and therefore requires protection.
Furthermore, because the fibre length is not fixed, there is a requirement for the apparatus to be adjustable to cater for the differing lengths, whilst maintaining a fixed position of the laser on the printed circuit board and a bracket upon which is mounted the connector at the fibre end.
An object of the present invention is to provide optical fibre storage apparatus which meets all the above mentioned criteria.
According to the present invention there is provided optical fibre storage apparatus comprising a bobbin around which optical fibre to be stored can be wound, the bobbin being formed by two pieces and being provided with means whereby it can be releasably secured to a support member, and means further being provided whereby the relative positions of the two halves of the bobbin on the support member can be adjusted to tension any optical fibre wound thereabout.
Accordingly to an aspect of the present invention, the fibre is connected at one end to a laser device, and is connected at the other end to a transmit optical connector.
According to a further aspect of the present invention, the support member is a printed circuit board.
The present invention provides the advantage of storing the optical fibre in a secure manner preventing damage thereto.
An embodiment of the present invention will now be described with reference to the accompanying drawings wherein: Figure 1 shows a perspective view of a printed circuit board showing a storage bobbin attached thereto accommodating an optical fibre, Figure 2 shows a plan view of a printed circuit board showing the bobbin attached thereto, and, Figure 3 shows a plan and elevation view of a bobbin.
In the drawings, like element bear the same reference number.
Referring to Figures 1, 2 and 3 a laser 2 is mounted to the board 1 via a heatsink 3. The bobbin 4A, 4B is shown mounted under the screened box 5, on mounting pillars 6, 7, 8 which form part of and extend from the screened box 5, and secured to the board 1 by nuts on the reverse side (not shown) Pillar 6 ensures that the two halves A and B of the bobbin 4 are kept apart. Pillar 7 registers with a corresponding hole in the bobbin 4A and the part 4A is substantially fixed in position.
The part 4B of the bobbin 4 has two slots 9, 10. Slot 10 locates about pillar 8, and slot 9 accommodates a fixing screw 11.
In use, the pig-tail optical fibre 12 extends from the laser 2, and is coiled around the bobbin 4 locating in groove 14, and the transmit optical connector 13 is securely mounted on the bulkhead 14. The part 4B of the bobbin 4 is moved away from part 4A to tension the optical fibre 12 and therefore locate it securely on the bobbin 4. The movement is provided by the slots 9, 10 and the pillar 6 acts as a pivot. When the fibre 12 is securely located, the screw 11 is tightened to hold part 4B in a secure position.
It will readily be appreciated by those skilled in the art that the present invention is not limited to the above described embodiment. The spirit and scope of the present invention may be extended to any environment where slack in a coiled fibre is to be taken up in order to secure the fibre.
