Description
Technical field
The present invention relates to a kind of light receiving and transmitting submodules of no-welding light guiding unit.
Background technology
In Fiber Optical Communication System, light receiving and transmitting submodule (Optical Sub-Assembly for Transceivers)
It is optical signal and the important medium in electric signal conversion, light receiving and transmitting submodule can be divided into the optical transport secondary module of transmitting optical signal
(Transmitting Optical Sub-Assembly, TOSA), the information of twocouese can be accommodated simultaneously in same optical fiber
Bidirectional light receiving and transmitting submodule (Bi-direction Optical Sub-Assembly, BOSA) and digital letter can be received simultaneously
Number and analog signal and three-dimensional light receiving and transmitting submodule (the Tri-direction Optical Sub- for emitting digital signal
Assembly, TRI-DI OSA) etc. types.As shown in Figure 1, illustrating using BOSA patterns as embodiment, there is a receiving originally
Body 10, receiving ontology 10 connects a luminescence unit 11 and a light guiding unit 12, and the luminescence unit 11 is made to be located at the receiving sheet
The central axis of body 10, and the luminescence unit 11 and the light guiding unit 12 is made to precisely align simultaneously coupling light.The light guiding unit 12
Be divided into tail-fiber type (Pigtail type) and female type (Receptacle type), this example with tail-fiber type light guiding unit into
Row explanation.
The receiving ontology 10 is internally provided with an optical filter 13, this will make the optical signal of luminescence unit 11 encounter optical filter
Refraction effect is generated after 13, as shown in the incident direction of arrow A1-A2, and then changes the focal position of optical signal, therefore, the light
Guide unit 12 need to make optical alignment by X, Y, Z axis mobile platform, so that the optical signal A2 of luminescence unit 11 draws with the light guide
The optical fiber 14 of unit 12 makees coupling optical registration, and so that the light guiding unit 12 is connected with the receiving ontology 10 using laser welding apparatus
It connects.But when laser welding is completed, which easy tos produce warpage (Warpage) because expanding with heat and contract with cold, and makes the light
Guide unit 12 can not touch with the receiving ontology 10 and then generate gap S completely, make luminous power displacement (Power shift),
In turn result in the loss of luminous power energy.
Invention content
Not having to what light guiding unit can be connect by welding with receiving ontology the main purpose of the present invention is to provide a kind of
The light receiving and transmitting submodule of no-welding light guiding unit, to solve problem of the prior art.
In order to achieve the above object, the light receiving and transmitting submodule of no-welding light guiding unit provided by the invention includes a receiving
Ontology, the receiving ontology can be used to connect a such as luminescence unit, a light guiding unit optical element, the upper end of the receiving ontology
Portion has an annular flange；The light guiding unit has a central siphon and a protective cover, is formed between the central siphon and the protective cover
There is an engaging space；And one fastener can be combined in the annular flange and engaging space, thereby allow the receiving ontology and the light guide
Drawing becomes combination but non-tightening state between unit, and so that the light guiding unit is made optical flat adjustment by a mobile platform,
Until the optical signal of the light guiding unit and the luminescence unit makees coupling optical registration, make the fastener, the receipts finally by solid
Hold ontology to connect with the light guiding unit.
