Description
Technical field
The present invention relates to optical communication equipment technology, especially a kind of focusing light wavelength division multiplexing.
Background technology
Optical communication field, OWDM refer in same root optical fiber while allow two or more light wave long letters
Number information is each transmitted by different optical channels, realize the light transmission of 1550nm wavelength or other wavelength, 1260nm-1490nm ripples
Long light reflexes to another optical fiber, and their basic demand is：Insertion loss is low, isolation is high, has good band logical special
Property, temperature stability is good, multiplexing number of vias has higher resolution ratio etc. more, and allow simultaneously in same root optical fiber two or
More than two optical wavelength signals are transmitted by different optical channel transmission or reflections.
Optic communication in recent years develops rapidly, and optical communication network turns into the basic platform of modern communication networks, and ripple is used in area of light
The mode being multiplexed is divided simply to improve transmission rate, optical signal, which realizes, to be directly multiplexed and amplify, and each wavelength is independent of one another, to transmission
Data format it is transparent, to its it is accurate require higher, traditional wavelength division multiplexer producer is in operation for the poly- of product
Jiao's positioning is difficult control, and existing light wavelength division multiplexing is typically directly pasted using diaphragm with lens, and product stationarity is not
Good, product parameters index can change during temperature cycles.
The content of the invention
The purpose of the present invention is aiming above mentioned problem existing for existing wavelength division multiplexer, there is provided and a kind of axiality is high,
The reliable and stable focusing light wavelength division multiplexing of optical signal transmission.
The present invention concrete scheme be：A kind of focusing light wavelength division multiplexing, includes the metal shell with inner chamber, metal
Enclosure is sequentially arranged with optical filter, parallel light lens, capillary glass tube, and capillary protective case is set with outside capillary glass tube,
One metal positioning ring is housed in the parallel light lens outer cover, the metal positioning ring is fitted close with metal shell internal chamber wall
Connection, the metal positioning ring is outwards equipped with 45 ° of inclination corner structures of a circle close to one end of optical filter from inner ring, in the filter
The outer end of mating plate is also associated with a condenser lens.
Heretofore described optical filter, parallel light lens and capillary glass tube are connected in the form of directly pasting.
Heretofore described condenser lens uses 0.23p G-Lens lens.
Heretofore described parallel light lens use 0.248p G-Lens lens.
Heretofore described parallel light lens, optical filter and metal positioning ring three coaxially assemble.
The beneficial effect that the present invention obtains：
First, parallel light lens are changed to metal retaining ring by original direct bonding and fixed, and stability is good, and retainer ring
45 ° of inclination corner structures are provided with close to optical filter one end, is easy to store the glue after solidifying, so makes the axiality and items of product
Parameter index does not change during temperature cycles, and transmission light path deviation angle is less than 0.5 °, and product quality is further
Lifting.
Second, after the design for employing metal retaining ring, lens, optical filter and capillary glass tube positioning and be bonded in batch
It is faster and better when quantifying to produce, and reduce every cost；By the accurate cooperation of metal positioning ring and metal shell,
Then condenser lens is directly aligned with light path, reduce the process that lens couple with light path, save the time, improve through
Ji benefit.
3rd, after the design structure for employing condenser lens, the coupling efficiency lifting 20% of telecommunication laser and this product with
On, 50% is can reach, improves the light energy of laser coupling optical fiber.
The present invention is simple in construction, and product axiality is high, stable and reliable for performance, simple production process, has actual well
Application value.
