Fiber optics work by guiding light down thin glass or plastic strands called optical fibers. Light reflects off the inner surface of these fibers due to total internal reflection. This allows light signals to be transmitted over long distances. For example, during WWII naval ships would use signal lights and Morse code to communicate by having sailors transmit messages to each other across ships. Optical fibers have advantages over copper wires like being less expensive, having a higher carrying capacity, and being well-suited for digital signals. They are also flexible and can transmit light signals without interference.

Fiber optics use thin strands of glass to transmit light signals for communication. They have a core that carries the light and a cladding that reflects the light down the core. There are two types of fibers - single-mode for infrared laser light and multi-mode for infrared LED light. Light travels through total internal reflection down the core due to the cladding not absorbing any light. Fiber optic systems have transmitters that encode light signals, fibers that conduct them, and receivers that decode the signals. Fiber optics offer advantages like lower costs, higher bandwidth, lighter weight, and flexibility compared to copper cables.

Fiber optic cables, connectors, and splices can be tested in three main ways: continuity testing using a visible light source, insertion loss testing to simulate system use, and OTDR testing which uses backscatter to locate faults. Continuity testing uses a fiber tracer or visual fault locator with an LED or laser to check for breaks. Insertion loss testing measures loss by comparing output levels with and without the cable under test. OTDR testing indirectly measures loss by analyzing backscattered light to create a display showing loss over distance.

Free space optics is a wireless communication technique that uses infrared rays to transmit data, voice, and video through the air instead of optical fibers. It has several advantages over fiber, including easier scalability to ultra-high bandwidth and lower costs since conversion between optical and electrical signals is not needed at each node. However, free space optics also faces challenges from physical obstructions in the transmission path and atmospheric effects like beam wander and scintillation that can distort the infrared beam. Overall, free space optics allows for cost-effective, quick, reliable, and secure optical connectivity.

Fiber optic attenuation is caused by absorption and scattering. Absorption is from molecules in the glass absorbing light and converting it to heat. Scattering occurs when light collides with glass atoms at angles outside the fiber's numerical aperture. Scattering is proportional to the inverse fourth power of wavelength, so longer wavelengths experience less attenuation. Together, absorption and scattering determine a fiber's attenuation curve. Single-mode fiber at 1550nm has the lowest attenuation of around 0.25 dB/km.

In conclusion, FSO provides a cost-effective option for short-range, high-speed data transmission where physical connections are impractical
Free space optics by Mayank Awasthi
Free space optics uses light propagating through free space to transmit data between two points. It provides line-of-sight connectivity at speeds up to 2.5 Gbps as an alternative to fiber cables when they are impractical. An FSO system consists of an optical transceiver with a laser transmitter and receiver to provide bidirectional communication over distances of several kilometers depending on the power of the transmitter. While offering rapid deployment over buildings on a campus, FSO is limited by fog, physical obstructions, and atmospheric effects like scattering that can reduce the intensity of the light beam.
Fso
The document discusses free space optical communication (FSO), which uses light propagating in free space to transmit data wirelessly. It describes the basic configurations of FSO as line of sight, directed non-line of sight, and non-directed non-line of sight. For indoor implementations, interference from light sources and eye safety are important considerations. Outdoor FSO is limited by atmospheric attenuation, with fog causing very high attenuation. The attenuation depends on wavelength due to scattering effects that vary with particle size. Scintillation noise from atmospheric inhomogeneities can also impact outdoor FSO but can be reduced with signal processing.

Fiber optic networks are used widely in telecommunications, CATV, and LANs. In telecom networks, fiber allows more phone conversations to be carried over a single pair of fibers than could be carried by thousands of copper pairs. Fiber is also used for CATV networks to improve reliability by reducing equipment failures. While fiber penetration is high for long distance LAN backbones, it is still low for connections to individual desks, though declining fiber costs and higher bandwidth needs are making fiber to the desktop more viable.

Fiber patch cords use thin glass optical fibers to transmit light signals between network devices like switches and routers over long distances with low signal loss. Different types of fiber patch cords, such as single-mode and multi-mode, are optimized for different network needs. Mechanical transfer registered jacks (MTRJ) are also commonly used optical fiber connectors that are smaller than standard connectors to reduce costs.
Free Space Optical Communication
Free space optical communication (FSO) uses lasers and photo detectors to transmit data through the air without fiber cables. It was initially developed by NASA and the military. FSO can transmit data, voice, or video at speeds up to 1.25 Gbps using invisible beams of light in a line-of-sight system. Signal propagation is impacted by weather like fog and rain, which can cause scattering and absorption leading to power losses and interruptions. While installation has low costs compared to fiber, FSO performance depends on clear line-of-sight conditions.
Single mode vs multimode fiber
Single mode fiber transmits a single mode of light via a laser, using a small 9/125 micron core. This results in less dispersion and higher bandwidth capabilities over longer distances of up to 10km. Multimode fiber transmits multiple modes of light via an LED, using larger 50/125 or 62.5/125 micron cores. This causes greater dispersion and limits transmission distances to around 550m, making it suitable mainly for internal or small campus use. The core sizes, light sources, transmission properties and distance limitations are the main differences between single mode and multimode fiber.

Fiber-optic lines consist of thin strands of glass that transmit digital information over long distances by carrying light signals. Hundreds or thousands of these optical fibers are bundled together in protective cable jackets to form optical cables. The fibers are used to transmit signals across oceans by connecting communication systems between ships thousands of miles apart.
How Fiber Optics Work
Fiber optics work by transmitting light signals through thin strands of glass that are bundled together in cables. Light travels down the fiber due to total internal reflection off the inner surface of the glass. Fiber optic cables are used to transmit digital information over long distances for phone systems, cable TV, and the internet due to their high bandwidth and ability to carry signals long distances without degradation.
Individual Slide Presentation
The document discusses how fiber optic cables work by transmitting light signals through thin glass strands and how this is used for communication networks. It explains that fiber optic cables have advantages over copper wires like lower costs, less signal degradation, and being ideally suited for digital signals. Additionally, it describes how optical fibers are manufactured through a process of making a glass cylinder preform and then drawing thin fiber strands from it.

- 1. How Fiber Optics Work
- 2. Fiber Optics Work Suppose you want to shine a flashlight beam down a long, straight hallway. You could place a mirror at the bend to reflect the light beam around the corner. You might line the walls with mirrors and angle the beam so that it bounces from side-to-side all along the hallway. This is exactly what happens in an optical fiber.
- 3. A Fiber-Optic Relay System To understand how optical fibers are used in communications systems, let's look at an example from a World War II movie or documentary where two naval ships in a fleet need to communicate with each other.One ship pulls up alongside the other. The captain of one ship sends a message to a sailor on deck. The sailor translates the message into Morse code and uses a signal light to send the message to the other ship. A sailor on the deck of the other ship sees the Morse code message, decodes it into English and sends the message up to the captain.
- 4. How Are Optical Fibers Made? Now that we know how fiber-optic systems work and why they are useful .Optical fibers are made of extremely pure optical glass. We think of a glass window as transparent, but the thicker the glass gets, the less transparent it becomes due to impurities in the glass. However, the glass in an optical fiber has far fewer impurities than window-pane glass.
- 5. Advantages of Fiber Optics Less expensive - Several miles of optical cable can be made cheaper than equivalent lengths of copper wire. Higher carrying capacity - Because optical fibers are thinner than copper wires, Light signals - Unlike electrical signals in copper wires, light signals from one fiber do not interfere with those of other fibers in the same cable
- 6. continuation Low power - Because signals in optical fibers degrade less, lower-power transmitters can be used instead of the high- voltage electrical transmitters needed for copper wires. Digital signals - Optical fibers are ideally suited for carrying digital information, which is especially useful in computer networks Flexible - Because fiber optics are so flexible and can transmit and receive light, they are used in many flexible digital camera for the following purposes:
