Description
Technical field
The utility model relates to a kind of novel polarization maintaining optical fibre flexible jumper and producing device thereof.
Background technology
At present, in actual light transmission since the suffered extraneous stress of optical fiber along with environment with variation of temperature and constantly variation.Therefore, the light polarization mode in the ordinary optic fibre is unsettled.If but introduced the interference that the light birefringence effect resists external STRESS VARIATION at inside of optical fibre, transmission polarisation of light mode in the optical fiber just could be kept.Polarization maintaining optical fibre just is being based on such principle and is keeping the stable transmission state of polarized light.
Along with the widespread use of Raman (RAMAN) device and the proposition of palarization multiplexing notion, protect inclined to one side device and be faced with huge market potential.Protect that (PM) part category is a lot of partially, the most common and consumption is maximum is exactly the polarization maintaining optical fibre flexible jumper.
Summary of the invention
The purpose of the utility model provides a kind of novel polarization maintaining optical fibre flexible jumper and producing device thereof.The utilization optical index is controlled the error at θ angle.Accomplish final key index (extinction ratio) is dynamically controlled.
The technical scheme of the utility model is:
A kind of novel polarization maintaining optical fibre flexible jumper comprises fibre core, stressed zone, ceramic contact pin and positioning key, and said stressed zone is arranged on the fibre core both sides, and ceramic contact pin is barrel-shaped, and it is outside to be arranged on fibre core and stressed zone, and positioning key is arranged on the ceramic contact pin outer wall.
The angle θ of deflection is that 0 degree is to 0.3 degree between the slow axis of said fibre core and the fast axle.
A kind of producing device of novel polarization maintaining optical fibre flexible jumper; Comprise collimating apparatus, polaroid, ring flange and extinction ratio meter; Polarization maintaining optical fibre flexible jumper to be made, collimating apparatus, polaroid, ring flange, polarization maintaining optical fibre flexible jumper to be made and extinction ratio meter are with this line spread; Polarization maintaining optical fibre flexible jumper one termination extinction ratio meter to be made, a termination are gone into said positioning key and are played folk prescription in consistent ring flange with polaroid.
The beneficial effect of the utility model is:
A kind of novel polarization maintaining optical fibre flexible jumper and the producing device thereof of the utility model.The utilization optical index is controlled the error at θ angle.Accomplish final key index (extinction ratio) is dynamically controlled, accuracy is good, and interchangeability is good, and is simple to operate, and efficient is high.
Description of drawings

The polarization maintaining optical fibre flexible jumper of the utility model is to locate through accurate localization key 6 to realize being coupled and aligned of polarization mode.Therefore, the polarization mode that guarantee to transmit in the optical fiber still keeps higher extinction ratio through behind the connector, fast axle 2 in the polarization maintaining optical fibre, slow axis 1, is key with aiming at of positioning key 6.
Like Fig. 2; A kind of producing device of novel polarization maintaining optical fibre flexible jumper; Comprise collimating apparatus 7, polaroid 8, ring flange 9 and extinction ratio meter 11; Polarization maintaining optical fibre flexible jumper 10 to be made, collimating apparatus 7, polaroid 8, ring flange 9, polarization maintaining optical fibre flexible jumper 10 to be made and extinction ratio meter 11 are with this line spread, and polarization maintaining optical fibre flexible jumper 10 1 termination extinction ratio meters 11, one terminations to be made are gone into said positioning key 6 and played folk prescription in consistent ring flange 9 with polaroid.
Light beam of light source incides on the polaroid 8 through a collimating apparatus 7, produces linearly polarized light, and polarization maintaining optical fibre flexible jumper 10 1 termination extinction ratio meters 11, one terminations to be made are gone into positioning key 6 and played folk prescription in consistent ring flange 9 with polaroid.Through rotation polarization maintaining optical fibre flexible jumper 10 inner contact pin assemblies to be made, stop operating when reading reaches requirement in extinction ratio meter 11.With rotating part contact pin assembly and not rotatable straight cover partial fixing, then other loose mails of assembly connector and grinding and polishing are promptly accomplished the making of polarization maintaining optical fibre flexible jumper then.
Embodiment recited above describes the preferred implementation of the utility model; Be not that design and scope to the utility model limits; Do not breaking away under the utility model design concept prerequisite; Common engineering technical personnel make the technical scheme of the utility model in this area various modification and improvement all should fall into the protection domain of the utility model, and the technology contents that the utility model is asked for protection all is documented in claims.
