Safety Precautions
Protective Eyewear
⚠️ CAUTION
To reduce the risk associated with eye injury:
- Safety glasses should be worn when handling chemicals and cleaving the optical fiber.
Chemical Precautions
⚠️ WARNING
To reduce the risk associated with fire:
- Storage, use and disposal of isopropyl alcohol should be per your company health, safety and environmental instructions. Refer to material safety data sheet for health hazards, safe handling, proper use and control measures.
Fiber Gel Irritation
⚠️ CAUTION
To reduce the risk associated with eye or skin irritation from fiber gel in connector:
- Product contains phenylmethyl silicone (63148-58-3), hydrophobic silica (68611-44-9) and may cause minimal eye irritation.
- Avoid contact with eyes and wash hands before eating or smoking.
- Upon eye contact, immediately flush eyes with water while holding eyelids open and continue flushing for ten minutes. Contact a physician.
- Upon skin contact, wash with soap and water. Refer to Safety Data Sheet for product information.
Bare Fiber Handling
⚠️ CAUTION
To reduce the risk associated with handling sharp glass fibers:
- Cleaved glass fibers are sharp and can pierce the skin. Use tweezers when handling shards and dispose of them properly per your company health and safety instructions.
Fiber/Cable Handling
? NOTICE
To reduce the risk associated with fiber damage:
- Optical fiber can be damaged by excessive tensile, compressive and bending forces. Consult the manufacturer's specifications for proper handling instructions.
LASER Safety
⚠️ CAUTION
To reduce the risk associated with eye damage from exposure to laser light:
- Take the proper precautions when working with optical fiber because invisible laser light may be present. The principal laser hazard when working with fiber optics is injury to the eye. Never look directly into the fiber or connector using the naked eye or a microscope.

2.5 Mark the fiber
Fully pull out the sliding connector nest from the cable holder. Put marking(s) on the fiber with a marking pen.
- 1st marking: at the edge of the holder body
- 2nd marking: at the indicator "0.9" (900um fiber only)

2.6 Strip 250µm fiber
Bring the sliding nest back to its original position. Strip buffer coating using the appropriate stripping tool.
Stripping 250µm fiber using disposable stripper:
Place the cable holder on the stripper such that the cable holder butts up against the stop. Close the stripper and pull out the cable holder.

Image: A close-up showing the cable holder butting against the stop on the stripper.
Caution: Do NOT OVERUSE the stripper (up to 20 stripping) or may damage stripped fiber.
Caution: Do NOT STRIP the same fiber twice or may damage the stripped fiber.
2.7 Strip 900µm fiber
Remove coating at the 2nd marking and outward with the appropriate stripping tool.
Image: A diagram showing the fiber with a section marked "Strip here" between the 2nd marking and the end.
Image: A hand using a stripping tool on the fiber.
2.8 Clean and test fiber
Thoroughly clean the stripped fiber with a lint-free wipe and alcohol or cleaning fluid.
Test the stripped fiber for weak points by using your finger to slowly flick the fiber in multiple directions. Watch for the fiber to spring back to the straight position. If the fiber breaks, properly dispose of the broken-off piece and repeat at Step 2.2.
Note: Do not touch bare glass 10mm from buffer end.
Diagram: Illustrates flicking the fiber and its expected return to a straight position, with dashed lines indicating movement.
2.9 Cleave the fiber
Place the cable holder on a cleaver and push it to the stop. Cleave the fiber per cleaver manufacturer's instruction.
Image: A hand holding the cable holder on a cleaver, with an arrow indicating pushing to the stop. Text "Holder butt up against stop" is present.
Note: If a cleave length gauge is installed on your cleaver, remove the gauge prior to connector installation. Save the cleave length gauge for later use.
2.10 Check cleave and strip length
Check for cleave length and strip length by pulling out the sliding connector nest of the cable holder.
