Optični oddajnik-sprejemnik 100G BIDI QSFP28 (imenujemo ga tudi 100G QSFP28 BIDI modul ali 100G QSFP28 oddajnik-sprejemnik z enim vlaknom) je visoko zmogljiv optični modul, ki pošilja in sprejema 100Gigabit Ethernet (100Nosi) prometa po eni sami niti enomodnega vlakna (SMF). Uporaba dvosmernega multipleksiranja z delitvijo valovnih dolžin (WDM), vsak modul oddaja in sprejema na različnih valovnih dolžinah (na primer, 1271 nm in 1331nm za 10 km povezavo). Ta inovativna zasnova podvoji zmogljivost vlaken in zmanjša stroške kablov za približno 50% v primerjavi s tradicionalnimi oddajniki-sprejemniki QSFP28 z dvojnimi vlakni. Kljub uporabi samo enega vlakna s preprostim priključkom LC, a 100G BIDI QSFP28 runs at full…

Optical fibers, made from glass or plastic, serve as efficient tools for transmitting light using the principle of total internal reflection. Encased in a flexible plastic sheath, these fibers can bend without breaking, offering a robust solution for information transmission. This article explores the working principles, types, and applications of optical fibers, shedding light on their significant role in modern communication. Working Principle Optical fibers operate on the principle of total internal reflection, ensuring minimal signal loss during transmission. At one end, a light-emitting device, such as a light-emitting diode or laser, sends light pulses into the fiber, while a…
