Optical fiber uses glass or plastic threads to transmit data in the form of light pulses. There are two main types: multimode fiber which uses LED lights and is used for shorter distances like campus networks; and single-mode fiber which uses lasers and is used for longer backbone networks of over 100km. Optical fiber has advantages over copper cables like higher bandwidth, longer transmission distances without signal loss, immunity to electromagnetic interference and lower security risks. However, it also has disadvantages such as fragility during installation and higher costs.

Optical fiber is the technology associated with data transmission using light pulses travelling along with a long fiber which is usually made of plastic or glass. Metal wires are preferred for transmission in optical fiber communication as signals travel with fewer damages. Optical fibers are also unaffected by electromagnetic interference. The fiber optical cable uses the application of total internal reflection of light. The fibers are designed such that they facilitate the propagation of light along with the optical fiber depending on the requirement of power and distance of transmission. Single-mode fiber is used for long-distance transmission, while multimode fiber is used for shorter distances. The outer cladding of these fibers needs better protection than metal wires.

These platforms offer a variety of content, including movies, TV shows, and original productions, allowing users to access content on-demand across multiple devices.The historical context covers the early days of streaming, starting with Netflix's inception in 1997 as a DVD rental service and its transition to streaming in 2007. The presentation also highlights India's television journey, from the launch of Doordarshan in 1959 to the introduction of Direct-to-Home (DTH) satellite television in 2000, which expanded viewing choices and set the stage for the rise of OTT platforms like Big Flix, Ditto TV, Sony LIV, Hotstar, and Netflix. The business models of OTT platforms are explored in detail. Subscription Video on Demand (SVOD) models, exemplified by Netflix and Amazon Prime Video, offer unlimited content access for a monthly fee. Transactional Video on Demand (TVOD) models, like iTunes and Sky Box Office, allow users to pay for individual pieces of content. Advertising-Based Video on Demand (AVOD) models, such as YouTube and Facebook Watch, provide free content supported by advertisements. Hybrid models combine elements of SVOD and AVOD, offering flexibility to cater to diverse audience preferences.
Content acquisition strategies are also discussed, highlighting the dual approach of purchasing broadcasting rights for existing films and TV shows and investing in original content production. This section underscores the importance of a robust content library in attracting and retaining subscribers.The presentation addresses the challenges faced by OTT platforms, including the unpredictability of content acquisition and audience preferences. It emphasizes the difficulty of balancing content investment with returns in a competitive market, the high costs associated with marketing, and the need for continuous innovation and adaptation to stay relevant.
The impact of OTT platforms on the Bollywood film industry is significant. The competition for viewers has led to a decrease in cinema ticket sales, affecting the revenue of Bollywood films that traditionally rely on theatrical releases. Additionally, OTT platforms now pay less for film rights due to the uncertain success of films in cinemas.
Looking ahead, the future of OTT in India appears promising. The market is expected to grow by 20% annually, reaching a value of ₹1200 billion by the end of the decade. The increasing availability of affordable smartphones and internet access will drive this growth, making OTT platforms a primary source of entertainment for many viewers.

- 4. 1 .What is optical fiber ? 2 Definition A technology that uses glass (or plastic) threads (fibers) to transmit data. A fiber optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves
- 5. 1 .What is optical fiber ? John Tyndall 1850’s Charles Kao & George Hockman 1965 Narinder Singh Kapany 1952 3
- 6. 1 .What is optical fiber ? 4
- 7. 2. How it works ? Fiber optics transmit data in the form of light particles that pulse through a fiber optic cable 5
- 8. 3. Different types Multimode type 6
- 9. 3. Different types Single-mode type 7
- 10. 3. Different types Comparison between the two modes • Small core • Less dispersion • Carry a single ray of light, usually generated from a laser. • Employed for long distance applications (100Km) • Uses as Backbone and distances of several thousands meters. •Larger core than single mode cable. •Allows greater dispersion and therefore, loss of signal. •Used for shorter distance application, but shorter than single- mode (up to 2Km) •It uses LED source that generates different angles along cable. •Often uses in LANs or small distances such as campus networks. 8
- 11. 4. Uses of optical fiber 9
- 12. 5. Advantages &disadvantages 10 Advantages •Extremely High Bandwidth •Longer Distance •Resistance to Electromagnetic Interference •Low Security Risk •Small Size •Light Weight •Easy to Accommodate Increasing Bandwidth
