Abstract
The invention relates to the field of an optical connector and especially relates to a single-mode fiber contact and a manufacture method thereof. The single-mode fiber contact comprises an insertion core and a single-mode fiber passing through the insertion core; and one end, at least corresponding to the insertion end of the insertion core, of the single-mode fiber is a thermal diffusion fiber formed through thermal diffusion. One end, at least corresponding to the insertion end of the insertion core, of the single-mode fiber of the single-mode fiber contact is the thermal diffusion fiber formed through thermal diffusion, so that during using, the refractive index distribution of the single-mode fiber changes along fiber axis center, and mode field diameter increases (can change from 9 micrometers to 55 micrometers); during optical signal transmission, optical energy is distributed to the core diameter of the enlarged single mode fiber, so that under the condition of not burning out the single-mode fiber contact, the optical signals can be effectively transmitted; and the single-mode fiber contact in the invention solves the problem that a conventional single-mode fiber contact can be easily burnt out when transmitting high-power optical signals.
Description
Technical field
The present invention relates to optical connector field, particularly relate to a kind of single-mode fiber contact element and manufacture method thereof.
Background technology
Single-mode fiber contact element is the signal transmission component used in general single mode fiber connector, the single-mode fiber comprising lock pin (being generally ceramic insertion core) and be located in lock pin, single-mode fiber generally adopts 9/125 optical fiber, because single-mode fiber core diameter is less only 9 microns, generally can only transmit the luminous power about 300 milliwatts, when transmitting powerful light signal, energy is too concentrated, very easily there is the problem of burning at two joints of optical fibre coupling parts, and then cause Signal transmissions to lose efficacy.
But, along with the continuous expansion of optical signal transmission in every field in recent years, the joints of optical fibre need the quantity of information of just transmission also to increase gradually, in the field that some are special, when needing the light signal transmitting relatively high power, then have to arrange external parts on single-mode optical fiber connector carry out process and could realize, this can make the structure of single-mode optical fiber connector become complicated on the one hand, increase the volume of single-mode optical fiber connector, too increase the production cost to single-mode optical fiber connector on the other hand.
Current large-power optical fiber connector generally adopts energy-transmission optic fibre, Lens Coupling technology realizes.Energy-transmission optic fibre is generally used for multimode form, optical fiber core diameter is larger, be generally 100/120,200/240 etc., luminous energy is distributed on optical fiber core diameter, ensure that good optical signal transmission, but which limit transmission mode, often cause signal transmission distortion due to the difference of mould field, namely multimode optical fiber cannot use in single-mode optical fiber connector.Lens Coupling technology is applied in the optical device such as collimating apparatus, laser instrument widely, play collimated light beam, the effect of high-octane light signal is transmitted after end face processing, this technology is comparatively ripe, but because collimating apparatus is comparatively strict to angle and size tolerance requirements, be generally pairing and use, be assembled in the joints of optical fibre requirement being difficult to reach any interchangeability, and cost is higher, batch production difficulty.
Summary of the invention
The object of the present invention is to provide a kind of single-mode fiber contact element, to solve the problem that existing single-mode fiber contact element easily burns when transmitting high-power.
Meanwhile, the present invention also aims to the manufacture method that above-mentioned single-mode fiber contact element is provided.
In order to solve the problem, single-mode fiber contact element is by the following technical solutions: single-mode fiber contact element, comprise lock pin and be through the single-mode fiber in lock pin, at least corresponding with lock pin inserted terminal one end of described single-mode fiber is the heat diffusion optical fiber that thermal diffusion is formed.
One end thermal diffusion only in lock pin of single-mode fiber forms heat diffusion optical fiber.
Adhesive is provided with between the outer peripheral face of described lock pin and the outer peripheral face of single-mode fiber.
The rear end of described lock pin is fixedly equipped with tubular type caudal peduncle, and the part coordinated with tubular type caudal peduncle of single-mode fiber has sheath.
The manufacture method of single-mode fiber contact element is by the following technical solutions: the manufacture method of single-mode fiber contact element, comprises the following steps: 1) heat-treated by single-mode fiber and form heat diffusion optical fiber; 2) by optical fiber heat treated for step 1) through in lock pin, make the end face of single-mode fiber concordant with the inserted terminal end face of lock pin, then injecting glue solidification.
Only the part of the medicine insertion lock pin of single-mode fiber is heat-treated in step 1).
Described lock pin is ceramic insertion core.
The rear end of described lock pin is fixedly equipped with tubular type caudal peduncle, and the part coordinated with tubular type caudal peduncle of single-mode fiber has sheath.
Because at least corresponding with lock pin inserted terminal one end of the single-mode fiber of this single-mode fiber contact element is the heat diffusion optical fiber that thermal diffusion is formed, therefore, when in use, the index distribution of single-mode fiber changes along optical fiber axle center, mode field diameter obtains increasing (can change to 55 microns from 9 microns), when transmitting optical signal, luminous energy is distributed on the single-mode fiber core diameter after expansion, the effective transmitting optical signal of energy when ensureing not burn, this single-mode fiber contact element solves the problem that existing single-mode fiber contact element easily burns when transmitting high-power.
Further, only one end thermal diffusion in lock pin of single-mode fiber being formed heat diffusion optical fiber is to reduce costs, and only one end thermal diffusion in lock pin of single-mode fiber is formed the demand that heat diffusion optical fiber just can meet most occasion through test; Adhesive is the reliability be combined with lock pin to strengthen single-mode fiber.
