Optical fiber study

Educational objectoves
• Present the components of an optical link
• Master the principles of optoelectronic data transfer
• Understand the role of an optical coupler
• Compare transmissions on optical media and RJ45
• Address the limits of copper compared to fiber (distances, flow rates, ...)
• Highlighting the main failures of an optical link
• Highlighting the main failures of an RJ45 link
• Manipulations and practical work on the model

Practical work provided
• Course questions (theoretical course written by a specialized trainer)
• Commissioning of a camera via the RJ45 network
• Commissioning of a camera via the fiber optic network using media converter
• Understand the value of a 4 to 1 coupler
• Highlighting the speed problem over a long RJ45 length
• Diagnosis and identification of common RJ45 faults (wire cut inversion of straight / crossed wiring, etc.)
• Diagnosis and identification of common fiber optic failures (cut fiber and strain on the fiber)
• Measurement on the RJ45 cable using a network tester
• Measurement on the optical fiber network thanks to a power meter and a light source on optical fiber
• Analysis of uplink and downlink speeds and internet latency via the RJ45 network and via fiber optics (this lab requires internet access)
