Abstract
A V-shaped groove cutting method for the joints of optical fibre, the method comprises: a, cut out concave plane along its length at the upper surface of the quartz substrate of the joints of optical fibre, and this lower concave plane corresponds to the top planes of V-shaped groove; B, on described lower concave plane, cut out multiple V-shaped groove arranged in parallel successively in the width direction.The present invention carries out substep cutting to quartz substrate, and each cutting quantity is less, and feed is more shallow, effectively can improve unbalance stress situation during cutting, thus meet cutting accuracy requirement.
Description
[technical field]
The present invention relates to the quartzy interface unit of connecting fiber (light transmitting fiber), particularly relate to a kind of V-shaped groove cutting method of the joints of optical fibre.
[background technology]
Optical-fibre communications is a kind of mode utilizing light and optical fiber to transmit information, belongs to the one of wire communication.Light just can carry information after modulation.From the eighties, optical-fibre communications makes telecommunications industry create revolutionary variation.Optical fiber communication is large with its transmission capacity, advantages such as good confidentiality and obtain high speed development, and has become current topmost wire communication mode.The two ends of optical fiber used in optical-fibre communications field need arrange the connector with optical-fibre communications equipment connection, and connector is made up of quartz substrate, it need the V-shaped groove cutting out multiple connecting fiber.As shown in Figure 1A, Figure 1B, tradition V-shaped groove cutting technique directly carries out overall processing cutting in the quartz substrate of bulk, because this kind of job operation depth of cut is darker, the material once cut more (it cuts part as shown in dotted line in Figure 1A), unbalance stress when causing cutting, and cause the error of depth of cut.
[summary of the invention]
The present invention is intended to solve the problem, and providing one to carry out substep cutting to quartz substrate, each cutting quantity is less, and feed is more shallow, effectively can improve unbalance stress situation during cutting, thus meet the V-shaped groove cutting method of the joints of optical fibre of cutting accuracy requirement.
For achieving the above object, the invention provides a kind of V-shaped groove cutting method of the joints of optical fibre, the method comprises:
A, cut out concave plane along its length at the upper surface of the quartz substrate of the joints of optical fibre, this lower concave plane corresponds to the top planes of V-shaped groove;
B, on described lower concave plane, cut out multiple V-shaped groove arranged in parallel successively in the width direction.
In step a, the height between described lower concave plane and the upper surface of quartz substrate is 0.04 ~ 0.08mm.
Height between described lower concave plane and the upper surface of quartz substrate is 0.06mm.
Centre distance between adjacent V-shaped groove is 0.11 ~ 0.13mm.
Angle between the two side of each V-shaped groove is 58 ° ~ 62 °, and its preferred angle is 60 °.
The width of the step of both sides, described lower concave plane is 0.4 ~ 0.6mm, and its preferable width is 0.5mm.
Contribution of the present invention is, its quartz substrate unbalance stress and depth of cut when cutting efficiently solving the joints of optical fibre has the problems such as error.Owing to carrying out substep cutting to quartz substrate, make each cutting quantity less, feed is more shallow, thus effectively can improve unbalance stress situation during cutting, and fully meet the accuracy requirement of cutting, substantially increase half-finished disposable qualification rate.

Fig. 2 is the inventive method schematic diagram, and wherein, Fig. 2 A is end view, and Fig. 2 B is schematic perspective view.
[embodiment]
The V-shaped groove cutting method of the joints of optical fibre of the present invention is as shown in Fig. 2 A, Fig. 2 B, the method comprises the steps: that the number of fibers connected as required intercepts different in width and length (thickness 1.5mm, for fixed value) quartz substrate, as joints of optical fibre blank 1, for 12 joints of optical fibre in this example.This joints of optical fibre blank is rectangular parallelepiped, processes a non-slotted plane 2 lower than joints of optical fibre blank upper surface in its back-end.Excessive by inclined-plane 3 between non-slotted plane 2 and joints of optical fibre blank upper surface, the angle between this inclined-plane 3 and non-slotted plane 2 is 45 °.
For reducing the degree of depth of a feed, first on the upper surface of joints of optical fibre blank 1, cut out a micron-sized lower concave plane 2 along its length with quartz cutter, this lower concave plane corresponds to the top planes of V-shaped groove.Both sides, described lower concave plane 2 form step 4, and the width of this step 4 is 0.4 ~ 0.6mm, and its preferable width is 0.5mm.Height between this lower concave plane 2 and upper surface of joints of optical fibre blank 1 is 0.04 ~ 0.08mm, and its preferred heights is 0.06mm.The width of the step of both sides, lower concave plane is 0.4 ~ 0.6mm, and its preferable width is 0.5mm.
Next, on described lower concave plane 2, cut out 12 V-shaped grooves 5 with quartz cutter, this V-shaped groove 5 is arranged in parallel successively in the width direction, and extends to described inclined-plane 3 from the front end of joints of optical fibre blank 1.Centre distance between two adjacent V-shaped grooves 5 is 0.11 ~ 0.13mm, and preferred center distance is 0.12mm.Angle between the two side of each V-shaped groove is 58 ° ~ 62 °, and its preferred angle is 60 °.Respectively can connect an optical fiber in 12 described V-shaped grooves, method of attachment is placed in described V-shaped groove 5 end of optical fiber, and fix by adhesive bonds.
Because method of the present invention is from described lower concave plane 2 feed, because this reducing the depth of cut, and being easier to location when cutting, therefore effectively improve cutting speed and efficiency.
