ArmenTel announces expansion of fiber-optic network coverage and launch of DWDM-based fiber-optic backbone networks.
The new network stretches from Armenia’s northern to southern frontier, providing transport network reservations, passing throughout the country.
In second halfyear of 2011, ArmenTel laid over 100 km of fiber-optic cable, also setting direct connection to backbone fiber-optic network in NKR.
Total length of ArmenTel’s fiber-optic network of exceeds 2770 km, with 326 km covering Yerevan.
In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (colours) of laser light. This technique enables bidirectional communications over one strand of fiber, as well as multiplication of capacity.
