PanARMENIAN.Net – ArmenTel announces expansion of fiber-optic network
coverage and launch of DWDM-based fiber-optic backbone networks.
The new network stretches from Armenia~Rs 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~Rs 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.
