Tips for Handling Fiber Optic Cables

Thursday 15th February 2024

Safely managing fiber optic cables is crucial to maintain their efficiency and prevent potential damage, despite their considerable tensile strength compared to copper. These cables consist of delicate glass tubes layered with polymeric materials.

Improper handling can lead to flawed connections and harm to optical components. Protective gear like safety glasses with side shields and gloves should always be worn when working with fiber.

Respecting the bend radius of the cable is essential. The bend radius indicates how tightly a cable can be bent without compromising its integrity—a value unique to each cable type, make, and length. Over-bending can break the glass within the cable, causing reflection and refraction that render it ineffective.

When connecting fiber cables to instruments, ensure proper anchoring to prevent them from hanging and bearing their own weight.

Avoid tightly strapping the cables or attaching them to objects that could lead to breakage. Excessive pressure on the cable can fracture the internal glass and make it prone to failure over time. Additionally, steer clear of sharp edges or angles that may cause warping or breakage.

Always keep connectors capped to prevent contamination from smudges, dust, or hair. These minute particles can significantly impair cable efficacy.

In the event of cable breakage, handle the damaged area with extreme care due to the hazard posed by tiny glass particles that can penetrate the skin.

When working with fiber optics, avoid looking directly into the cable or placing the laser source in front of your eyes. Prioritize disconnecting fiber cables from the laser source before handling, and use a power meter to confirm the fiber is inactive.
