Crafting a fiber optic patch cord involves a meticulous production process to ensure the high standards of connectivity and performance.

This blog post delves into the intricate steps of assembling a fiber optic patch cord.

Introducing the important roles of fiber optic patch cord production machines.

Step 1: Precision Cutting

The initial stage in the production of a 2.0/3.0mm fiber optic patch cord begins with a precision cutting machine.

It is expertly trim optical fiber to exact specifications with impeccable accuracy.

For the more delicate 0.9mm fibers, manual cutting need to ensure the finer control necessary for these slender strands.

Step 2: Manual Connector Assembly

Next, technicians manually prepare the fiber for connector attachment:

  • For 2.0/3.0mm fibers, the outer jacket strip back approximately 2cm and cleanly remove the aramid yarn. This step is not necessary for the thinner 0.9mm fibers.
  • All fibers, including the 0.9mm variety, then receive the boot, stop ring and spring, which are essential components of the connector assembly.

Step 3: Ferrule Assembly

The ferrule assembly process combines manual dexterity with machine-assisted precision:

  • A brief heating of the ferrule and inner-jacketed fiber, lasting 5-10 seconds, is perform for 2.0/3.0mm fibers.
  • Remove the white inner jacket and coat, the coat need to strip enough.
  • The ferrule is then aligned and smoothly inserted onto the fiber.
  • A curing oven solidifies the assembly, setting the ferrule in place after a 10-minute process.

Step 4: Final Connector Assembly

The remaining connector parts are assembled manually, ensuring the internal structure is secure and ready for the crucial grinding step.

Step 5: Automated Grinding Process

The grinding process, executed by sophisticated machines, involves four detailed stages to perfect the connector end-face:

  • D30 Grinding Film: Rough grinding carry out for about 38 seconds.
  • D9 Grinding Film:  Remove excess glue is, with additional passes if residue remains visible.
  • D1 Grinding Film: Fine scratches smooth out to refine the connector’s surface.
  • Polishing Film: The final polish eliminates any remaining fine scratches.

Step 6: Quality Assurance

Quality testing machines, such as the Quadrangle Grinding Machine and End Face Inspection Machine. It play a crucial role in ensuring the connector surfaces.

  • When dealing with small quantities, connectors must be evenly distributed for testing.
  • Any detected excess glue or scratches prompt a change in the corresponding grinding film to achieve the desired finish.

Step 7: Performance Testing

Using an IL&RL tester at 1310/1550 nanometers to test the Insertion Loss (IL) and Return Loss (RL) of each single-mode connector:

Test the Insert Loss
  • UPC Connectors: Aim for IL less than 0.3dB and RL more than 50dB.
  • APC Connectors: Strive for IL less than 0.3dB and RL more than 55dB.
  • For customers with specific data requirements for patch cords or pigtails, these metrics are pivotal.
  • In the absence of stringent requirements, a Four-channel red light source may suffice for basic pass-through light testing.
