TRENDS in MIDDLE EAST in Broadcast Transition to Digital Broadcast Transition to HD and UHD Using Fiber Optics in Broadcast
The Idea
Type of fibre: Single mode Core diameter/cladding are typically 9/125um Typical light source is a Laser @ 1310nm, 1550 and 1625nm wavelengths LASER, an acronym - Light Amplification by the Stimulated Emission of Radiation.
Loss Mechanism in fibres MACROBENDING Macro bending loses occur when fibres are physically bent beyond the point of critical angle. In general a bend radius < 25-20 mm is recommended for any standard fibre. Certain Bend Insensitive fibres do however claim to tolerate a bend radius of as little as 5mm. However this may reduce fibre life due to increased stress.
How information travels Basic Optical Transmission System? Input Signal Transmitter Modulator Optical Source Optical Detector Demodulator Receiver Output Signal
Advantages of fibre optics Higher carrying capacity / increased bandwidth. Less signal degradation - longer distances possible without regeneration Smaller size & lighter weight Interference immunity no EMC issue Transmission security - very difficult to tap Non flammable - no electricity, thus no fire hazard Very flexible cables - endoscopes, inspection
Disadvantages of fibre optics Cost: a fibre optic solution may sometimes appear expensive compared to a copper solution Termination of fibre cable is more complex and requires special tools and precision / careful workmanship Fibre optic cables are potentially more fragile than coaxial cables, sharp bends could break the fibre Needs more expensive optical transmitters and receivers Cannot carry electrical power

Maintenance
Maintenance We Should keep the network alive and ready all the time.
Fibre optic installation require regular cleaning of the fibre to prevent loss of image quality
One of the most overlooked aspects of fiber optic maintenance and troubleshooting is keeping the end of the ferrule clean Video inspection tool Cap protection Regular cleaning https://www.youtube.com/watch?v=s9nyt3gs XK8
