Abstract
The utility model is related to a kind of transmission-type isolation optical splitter, including single fiber collimater, multi-fiber collimater, isolator and valve jacket, the isolation optical splitter also includes waveguide light-splitting chip, the single fiber collimater, isolator, waveguide light-splitting chip and multi-fiber collimater are set gradually, and encapsulate fixation with the valve jacket.Because waveguide light-splitting chip does not only have the function of light splitting, also small volume feature can reduce the volume of optical splitter.When single beam is injected from single fiber collimater, after isolator, multichannel light is uniformly divided into by waveguide light-splitting chip, any light all the way in the multichannel light does not interfere with other light paths.
Description
Technical field
The utility model belongs to optical path converter field, and in particular to a kind of transmission-type isolates optical splitter.
Background technology
With the development of optical transport network technology, the market application of optical splitter is greatly improved, while as electronics is set

The utility model is achieved in that a kind of transmission-type isolation optical splitter of offer, including single fiber collimater, multi-fiber standard
Straight device, isolator and valve jacket, the isolation optical splitter also include waveguide light-splitting chip, the single fiber collimater, isolator, waveguide
Light splitting chip and multi-fiber collimater are set gradually, and encapsulate fixation with the valve jacket.
Further, the multi-fiber collimater includes multi-fiber fiber optic head and the first Lens lens, and the multi-fiber fiber optic head is consolidated
It is located in one end of valve jacket, the first Lens lens are arranged between the isolator and the waveguide light-splitting chip.
Further, the multi-fiber collimater also includes many fiber coating pipes, and the multi-fiber fiber optic head is encapsulated in many fiber coating pipes,
Many fiber coating pipes are arranged between the valve jacket and multi-fiber fiber optic head.
Further, the single fiber collimater includes single fiber optical fiber head and the 2nd Lens lens, and the single fiber optical fiber head is consolidated
It is located in the other end of valve jacket, the 2nd Lens lens are arranged between the isolator and single fiber optical fiber head.
Further, the single fiber collimater also includes single fiber sleeve pipe, the single fiber optical fiber head and the 2nd Lens lens
One end is encapsulated in single fiber sleeve pipe, and the single fiber sleeve pipe is arranged between the valve jacket and single fiber optical fiber head.
Compared with prior art, a kind of transmission-type isolation optical splitter of the present utility model, due to waveguide light-splitting chip not only
There is a function of light splitting, also small volume feature, the volume of optical splitter can be reduced.When single beam is injected from single fiber collimater, pass through
After isolator, multichannel light is uniformly divided into by waveguide light-splitting chip, any light all the way in the multichannel light does not interfere with other light paths.
Brief description of the drawings
