Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, a kind of closeness height, precision is good, volume the is little double-deck parallel optical fibre array of single mode are provided.
Purpose of the present invention is achieved through the following technical solutions:
The double-deck parallel optical fibre array of a kind of single mode, characteristics are: comprise MT head and two-layer optical fiber orientation bridgeware up and down, every layer of optical fiber orientation bridgeware all is carved with the V-type groove, the end face that is used for the optical fiber coupling of optical fiber orientation bridgeware is perpendicular to surface level or fall acute angle to the inside, wherein, place the fibre ribbon that is used for the light signal input in the V-type groove of one optical fiber orientation bridgeware, place the fibre ribbon that is used for light signal output in the V-type groove of another optical fiber orientation bridgeware.
Further, the double-deck parallel optical fibre array of above-mentioned a kind of single mode, described every layer of optical fiber orientation bridgeware all is carved with at least four V-type grooves.
Further, the double-deck parallel optical fibre array of above-mentioned a kind of single mode, the V-type groove of the V-type groove of the optical fiber orientation bridgeware on described upper strata and the optical fiber orientation bridgeware of lower floor staggers mutually.
Again further, the double-deck parallel optical fibre array of above-mentioned a kind of single mode, described optical fiber orientation bridgeware comprises base plate, overlay and fibre ribbon, backplate surface is provided with step, top bar and be carved with the V-type groove, getting out of a predicament or an embarrassing situation is the plane, places the naked fibre of optical fiber in the V-type groove, the naked fine length of optical fiber is consistent with the length of topping bar, and is stamped overlay on it.
Again further, the double-deck parallel optical fibre array of above-mentioned a kind of single mode, by solidifying glue bond, the optical fiber orientation bridgeware on described upper strata and the optical fiber of lower floor are orientated between the bridgeware by solidifying glue bond between described overlay and the base plate.
Substantive distinguishing features and obvious improvement that technical solution of the present invention is outstanding are mainly reflected in:
Double-layer fiber array closeness height of the present invention, precision is good, volume is little, and the fibre ribbon that is used for light signal input and light signal output is placed apart, in the assurance high coupling efficiency, increases the fiber array closeness to the utmost.
