Dense Wavelength Division Multiplexing (DWDM) is an optical multiplexing technology used to increase bandwidth over existing fiber networks. DWDM works by combining and transmitting multiple signals simultaneously at different wavelengths on the same fiber.
Hossein Ansari, the project’s technical expert, told MNA correspondent DWDM is the first and only domestic production in the field of data transmission across the Internet via fiber optics, saying the advantage of this system is that it can transfer a large amount of data traffic through one single fiber optic.
He noted that the carrying capacity of one fiber is 10Gb/s, adding the system can transmit a total of 800Gb/s and thus meets all the needs of the country’s communication infrastructure.
“The Iranian DWDM is currently installed on Tehran to Isfahan route which is considered as the country’s most important communication route that can transmit Internet traffic to southern cities such as Shiraz, Bandar Abbas, Bushehr, Isfahan and Khuzestan.
Adding that prior to this, the DWDM was imported from abroad, Ansari maintained the system’s software and hardware have been completely indigenized and as such provide a secure route for data transmission across the country.
