2 core adapters i.e. 2 core fibre connectors use bayonet coupling, and convenient and efficient, outer dimension is equal to standard FC
Connector.This connector construction integrated level is higher, and structural principle has already passed through the various equipment such as airborne, vehicle-mounted, ground
Long-term test, it is stable and reliable for performance.
The specific manufacturing process of the present embodiment is as follows:
Formation fixed value attenuator after fibre optic attenuator completes is first passed through, in conjunction with the structural type of 2 core armored optical cables
Formula is packaged, and forms integrated 2 cores decaying optical cable.
One, fibre optic attenuator manufacturing process is as follows:
Draw the fixed fibre optic attenuator production of tapered 10dB and packaging technology
Light, which divides towpath device mainly, 2 seed types:
One is the optical fiber splitters using traditional oxyhydrogen flame fused biconical taper (FBT);
Another kind is planar optical waveguide (PLC) optical splitter using integrated optics technique production.
1, fused biconical taper formula (FBT) mono-/multi- mode fiber splitter technique
FBT optical fiber splitter is mainly optical fiber, manufacture craft mainly include include optical fiber fused tapering, coupled zone encapsulation
(encapsulation, two encapsulation, three encapsulation together).
Optical fiber fused tapering process are as follows:: heating melting finally generates one section of two-way circle simultaneously to 2 side stretchings under flame high temperature
Wimble structure, the optical signal of input occur power in the coupled zone of this bicone structure and reallocate, and make a part of light from " straight-through
Arm " optical fiber continues to transmit, and another part light is transmitted from " coupling arm " optical fiber.
Fused biconical taper cardinal principle by control technological parameter such as tensile speed, is stretched using " weakly coupled-mode theory "

Energy.
Coupled zone encapsulation specifically includes that one of encapsulation (quartz base plate), two encapsulation (glass tube), three encapsulation (steel
Pipe), guarantee the reliability of the engineer application of full fiber type splitter.
2, fixed fibre optic attenuator (1 × 2 multimode splitter) main indicator of 10dB
The fixation fibre optic attenuator mainly solves high/low temperature under military environment (- 55 DEG C~+85 DEG C), vibratory impulse, height
Reliably, small integrated, fixed splitting ratio rigors, reach military products class requirement.In the current behaviour in service of ancillary engineering facility
Well.
The related specification of the 10dB of the present embodiment fixed fibre optic attenuator (1 × 2 multimode splitter) is as follows:
Two, integrated 2 cores decaying connector design
Integrated 2 cores decaying connector uses bayonet coupling, and convenient and efficient, outer dimension is equal to standard FC connection
Device.
As shown in figure 3, connector construction uses dual spring system light channel structure, the spring at adapter both ends is in butt coupling mistake
It is compressible in journey, and provide to relay, a framework spring first provides the engagement force of connector plug and socket, and buffering is outer
The interference that boundary vibrates, impacts, while primary positioning is carried out to optical path, the stable optical path of next 2 light terminal springs, guarantee light terminal
Reliable contacts.Connector is positioned using 3 keys, and 1 major key and 2 auxiliary bonds are of different size, prevent from mispluging and pull out.Integrated level is higher,
Its structural principle has already passed through the long-term test of the various equipment such as airborne, vehicle-mounted, ground, stable and reliable for performance.
1) 2 core of all-in-one micro decaying wire jumper mating surface design
As shown in figure 4,2 core of all-in-one micro decaying wire jumper is positioned using 3 keys, close face angle degree for 140 °, 75 ° and
145°.And it is 145 °, 75 ° and 140 ° that the pin connector of module end, which closes face angle degree, 1 major key and 2 auxiliary bonds are of different size, prevent
It only misplugs and pulls out.
The engagement force of 2 core connector plugs and duplex, can buffer the interference of extraneous vibration, impact, while right
Optical path carries out precision positioning, guarantees the reliable contacts of light terminal.This duplex needs to guarantee 2 core fibre low insertion losses
Unanimously.For this purpose, we devise " floating porcelain bushing structure ".Parallel light path and optics support structure have certain gap, and
Ceramic insertion core is connect with optics support structure by floating spring, can be floated in a certain range.In this way, when optical path bearing knot
Structure is influenced by external force or temperature, and when so that generating angle offset between pilot hole, parallel light path " floating ", 2 ceramics are inserted
By porcelain bushing automatic centering, structure ensure that non-interference between multi-core optical fiber core, and cable assembly is made to can be realized multicore
Optical fiber low-loss consistency is fine.
2) casing and its alignment design
In order to obtain 0.5dB loss below in the connection of multimode fibre, it is necessary to 2 optical fiber pair of done with high accuracy
Standard, and optical fiber connector is needed to still ensure that fine registration in the case where plugging repeatedly.The processing request of casing reaches sub-micron
Precision.In casing processing, especially important size is outer diameter, aperture and the bias in hole of casing.
3) integrated dustproof design
2 core of all-in-one micro decays wire jumper using integrated design, wherein playing the porcelain bushing of light connects alignment effect
It is encapsulated in the inside of 2 core of all-in-one micro decaying wire jumper, there is radial dustproof effect.And 2 core of all-in-one micro decaying wire jumper
By the way of being horizontally mounted, the dust in airborne circumstance will not fall directly into 2 core of all-in-one micro decaying wire jumper inner ceramic
In casing, so the decaying wire jumper integrated design of 2 core of all-in-one micro has certain dust-proof effect.
2 core of the all-in-one micro decaying jumper wire plug socket connection of the present embodiment belongs to mechanical tight fit, and joint gap is small
In 0.05mm, general granule foreign be cannot be introduced into inside connector.And 2 core connectors and duplex junction have
The dust of sealing ring, the light loss that can will not have an impact with secondary dust-proof, in course of normal operation enters.As long as 2 core connectors with
Duplex separation can cover dust cap in time, and will play prevents contaminated effect.
4) low-loss designs
The meaning of this index is junction loss requirement≤0.5dB after 2 plugs and assembly assembly, repeatability≤
0.3dB, interchangeability≤0.3dB, influence this project indicator because being known as the following:
1, control with raw material
The raw material of most critical are ceramic ferrule in connector, it directly influences transverse direction when optical fiber connector docking
Deviation, angular deviation, gap, these parameters directly determine the insertion loss index of connector.
In actual optical fiber connector, caused by the structure design of end face pretightning force has been substantially absent because of gap
Loss.Therefore, how to reduce the key that lateral deviation and angular deviation are just developed at optical fiber connector, ceramic ferrule conduct
Key raw material, its screening seem particularly necessary, it is the preliminary guarantee for producing high quality connector.
2, termination power design:
End face contact force when ceramic contact pin docks in optical fiber connector, there are a best force value, standard provides contact pin
Body end face stress should be between 7.8~11.8N.
For miniature connector designed by the present embodiment, it is as follows to design spring parameter:
1, material: stainless steel, shear modulus G=80000Mpa
2, spring filament diameter: d=Φ 0.4mm, central diameter D=Φ 2.4mm curl up ratio=6
4, number of total coils=8+2;Number of active coils=8, bracing ring=2, free height 9.3mm
5, a length of 6mm of connector spring cavity design
Calculating the termination power that single spring generates as follows is 8.1N
The termination power that so 2 springs generate is 16.2N, removes the withdrawal force 5N of porcelain bushing, connector plug and is inserted
Endface of ferrule stress is 11.2N when seat inserting, meets design requirement.
3, grinding technics:
When often requiring that interchangeability and repeatability index in connector production, when generally use the more set of connectors of production at
Product are interchangeable test, filter out the sample for being able to satisfy interchangeability index.
After the present embodiment is using fibre optic interferometer, precision control fiber end face quality, for the first time repeatability and interchangeability
Index carries out parametric control and proposes following Con trolling index according to production experience in recent years:
Screening programme | It is required that | Instrument | |
1 | Apex offset | ≤50μm | Micrometer |
2 | Optical fiber height | ±50μm | Degree of eccentricity tester |
3 | Radius of curvature | 7 μm~25 μm | Standard divider |
