Questions and Answers
What is the first step after cleaving the fiber?
Measure and mark an additional 11 mm on the fiber jacket.
How should the connector be loaded into the tool?
Insert it lead-in tube first into the wrench and guide it into the connector cradle while releasing the load button.
What should be done after closing the cover?
Check for the error light. If it remains off, proceed with inserting the cleaved fiber into the lead-in tube.
Where should the visual mark be located after inserting the fiber into the lead-in tube?

Study Notes
Fiber Optic Cable Preparation
- After cleaving the fiber, the first step is to clean the bare fiber.
- Connectors should be loaded into the tool with the connector body facing the crimp nest and the fiber stub aligned with the cleaved fiber.
Fiber Insertion
- After closing the cover, the fiber should be seated in the connector and the position of the fiber marked.
- The visual mark should be located 1-2 mm beyond the end of the lead-in tube after inserting the fiber.
Cable Preparation
- After sliding the strain-relief boot onto the cable, the first step is to secure the boot to the cable.
- The 900-micron tight buffer should be removed from the cable by using a buffer tube stripper or a slice-and-dice method.
Fiber Handling
- When sliding the jacket off the fiber, avoid twisting or bending the fiber to prevent damage.
- The bare fiber should be cleaned with isopropyl alcohol and a lint-free wipe after removing the 250-micron coating.
Fiber Optic Cable Characteristics
- Single-mode fiber optic cables typically have a core diameter range of 8-10 microns.
- The main difference between single-mode and multimode fiber optic cables is that single-mode cables transmit light in a single path, while multimode cables transmit light in multiple paths.
Multimode Fiber Applications
- Multimode fiber optic cables typically use wavelengths of 850 nm and 1300 nm in LAN applications.
FC Fiber Optic Connectors
- FC fiber optic connectors have a key feature of a screw-on locking mechanism and are typically used in high-density applications, such as data centers and telecommunications.
