SGRASSPODSAnalysis of data transmission in information systemsCurrently, large and small businesses have turned to fiber optic cable to measure data transmission speed Fiber optic cable is a long thin cable, about the diameter of a human hair, composed of a central conductor of glass or plastic that has been
Page | 19 MANAGEMENT INFORMATION SYSTEMS fabricated and optimally bundled together to allow transmission max away the light signal Optical fibers are coated with a lining to reflect light signals well and limit breakage and have the ability to transmit signals over long distances Unlike copper cable, which transmits electrical signals, fiber optic cable is less prone to interference, high data transmission rate, and longer distance
For Dien May Xanh, they used optical fiber in the application of "Single mode cable", which is characterized by low signal loss, so it can be used for long distances of thousands of kilometers, popular in telephone networks, cable TV network, the internet without amplification Enables internal delivery of washing machine products to the website quickly and smoothly to customers visiting the site
Dien May Xanh has used optical cables to transmit data in the fastest way because optical cables are made of materials such as glass or thin plastic, smaller in diameter and lighter than copper cables
Higher load capacity because optical fiber is thinner than copper cable, can bundle more fiber into given diameter than copper cable allowing more channels to go through your cable because the signal transmission line is light, it rarely loses or degrades the transmission signal, without interference, so the quality of the transmission line in optical cable is better than copper cable
Because the signal loss in fiber optic cable is less so that less power can be used, the transmitter can use a lower power source instead of the high voltage transmitter used in copper cable
Fiber optic cable is suitable for carrying digital information, which is extremely useful in computer networks, which copper networks cannot do
Because of the use of light transmission, no electricity passes through the fiber optic cable, the risk of fire is almost zero
