Multi Polarization Maintaining Fiber Alignment System
PMF-421P-FA16（FA+MT）
Product Description：
In response to customer demand, Neofibo has designed an all-in-one FA and MT fiber alignment system by integrating FA and MT alignment features, which can complete the alignment of different products by simply replacing the tooling and achieve multi-purpose use without affecting the accuracy of the alignment.
This equipment adopts high-definition camera and internal/external light source to ensure clear imaging of the fiber end-face, ensure accurate alignment of the catenary, efficient dispensing or replenishment operation, and finally complete the heating and pre-curing. Customized horizontal and vertical grid lines ensure that the angular deviation after alignment is far less than ±3 degrees. Its excellent alignment accuracy effectively reduces optical signal transmission loss.
Model: PMF-421P-FA16（FA+MT）
Place of Origin: Shenzhen, China
Key Feature:
- Suitable for 16-core FA fiber array or MT PM fiber alignment, which is efficient in operation and multi-purpose;
- Can realize heat curing or UV curing;
- High-definition camera imaging 100-800 times magnification, effectively control the alignment angle is less than ± 3 degrees;
- Multiple horizontal and vertical grid lines to ensure fast and slow axis consistency;
- 3-axis adjustment frame precision control, fine-tuning accuracy ± 0.01mm;
- Internal and external light source to ensure clear end-face imaging of the PM fiber;
- 600x500mm optical platform is convenient for system expansion;
- After the catenary alignment is completed, it can be heated and pre-cured or UV cured directly in the fiber ferrule or capillary tube;
- Spindle adjustment angle 0~360 degrees.

Operation procedure (UV curing FA ferrule or 353ND adhesive heat curing MT/single core ceramic ferrule)：
(1) Strip the fiber coating layer, 125um core length 22-30mm;
(2) Cutting fiber: use fiber optic cutting knife, fiber length 12-15mm;
(3) Dispensing: Inject an appropriate amount of 353ND epoxy glue into the fiber;
(4) Fixing the fiber: Fix the FA fiber on the positioning piece, with the dispensing window upward;
(5) Clean the fiber: use a cotton swab to clean the front end of the fiber, remove dirt, clearly visible panda eyes;
(6) Alignment axis: the FA fiber to keep the polarization maintaining rotation of the alignment axis, the panda’s eye placed in the correct position, fixed fiber position, to prevent rotation after the alignment axis, to complete the next step after fixing the alignment axis;
(7) Pre-curing: turn on the pre-curing switch, heating 5-10 minutes initial curing 353ND glue;
(8) Fully cured: the pre-cured ferrule and connectors placed in the curing oven for a full 15 minutes at 120 degrees heat curing;
(9) Assembly: the cured ceramic ferrules will be assembled into a finished connector and complete the crimp, FA ferrules do not need to be assembled directly mounted on the disk grinding;
(10) Polishing: through 4~5 polishing to complete the fiber end-face polishing;
(11) 3D test: as needed to detect the connector 3D geometric parameters, if not required, may not test;
(12) End-face inspection: check the fiber end-face for scratches / no white spots / no black spots / no edge breaks and other defects, if not judged as good;
(13) Extinction ratio and loss test: use special polarization extinction ratio tester and broadband light source to complete the test, according to customer standards to determine the product【OK】 and 【NG】.
