The main principle that keeps light inside the fiber core.

What is Total Internal Reflection?

100

The standard jacket color used to identify Single-mode fiber optic cables.

What is Yellow?

100

The common connector type known for its small form factor and push-pull latching mechanism.

What is the LC Connector?

100

The simplest, most common light source used for short-distance, low-speed Multimode fiber links.

What is an LED?

100

The number of sides on a stop sign.

What is eight?

200

The material typically used for the core of most high-performance optical fibers.

What is Glass (or Silica)?

200

The component within a loose-tube cable that prevents water intrusion.

What is Gel (or water-blocking gel)?

200

The process of permanently joining two fibers by melting their glass ends together.

What is Fusion Splicing?

200

This component converts the weak optical signal back into an electrical signal at the receiving end of a fiber link.

What is a Detector (or Photodetector / Photodiode)?

200

The largest organ of the human body.

What is the Skin?

300

The two common core diameters, typically 50 $\mu$m and 62.5 $\mu$m, used for this type of fiber.

What is Multimode?

300

This type of cable rating is required for use in vertical shafts or runs between floors in a building.

What is Riser (or Riser-rated)?

300

The term for a connector that is shaped like a square and uses a push-pull mechanism, often replacing the ST connector.

What is the SC Connector?

300

The light source required for Single-mode fiber because it emits a focused, coherent beam.

What is a Laser (or Semiconductor Laser)?

300

The country where the sport of Judo originated.

What is Japan?

The two most common wavelengths for Single-mode fiber operation, expressed in nm.

What are 1310 and 1550?

400

The two types of sheaths applied to the fiber itself: Primary coating and this outer colored layer.

What is the Secondary Buffer?

400

This essential tool removes the protective buffer layers from a fiber end before cleaving or splicing.

What is a Fiber Stripper?

400

The term for a device that includes both a fiber-optic transmitter and a receiver in a single package.

What is a Transceiver?

400

The process by which plants convert light energy into chemical energy.

What is Photosynthesis?

500

The unit of measurement for optical power loss along a fiber, represented by the abbreviation dB.

What is the Decibel?

500

The primary hazard when handling bare optical fiber that requires a proper disposal method.

What are Fiber scraps (or glass shards)?

500

This key geometric alignment factor is measured when inspecting a ferrule's end-face, referring to the core's position relative to the center.

What is Concentricity?

500

The acronym for a highly sensitive detector that uses an internal multiplication effect to amplify the light signal.

What is APD (or Avalanche Photodiode)?

500

The only letter in the English alphabet that is not found on the periodic table.

What is the letter J?
