Ethiopia's Ethio Telecom selects ZTE to build 100 Gbit/s DWDM/OTN backbone network
Announced Date: 3/8/2016 Published Date: 3/9/2016

ZTE announced is has been selected by Ethiopia's Ethio Telecom, which serves more than 40 million subscribers, to construct a 100 Gbit/s DWDM/OTN backbone transmission network covering the western and southern regions of the country.

Ethio Telecom is an integrated telecom service provider in Ethiopia, providing fixed-line, mobile and Internet services. With the rapid development of 2G, 3G and LTE mobile and fixed-line voice and broadband services, Ethio Telecom requires a high-capacity national transmission backbone network to meet increasing bandwidth transmission requirements.

The 100 Gbit/s DWDM/OTN transmission backbone network to be supplied by ZTE will enable higher speed network transmission through increasing network capacity 10-fold and helping Ethio Telecom to expand the roll-out of 3G, LTE and fixed-line broadband services.

ZTE's solution is based on 100 Gbit/s DWDM/OTN technology that integrates intelligent WASON (WDM automatic switch optical network) and features polarisation-division multiplexing quadrature phase shift keying (PM-QPSK) modulation, coherent reception and software decision forward error correction (SD-FEC) key technologies.

The transmission backbone network will be designed to support large-capacity OTN cross-connect and ultra-long distance transmission and to enable optical network intelligent scheduling. These capabilities will help Ethio telecom to meet demand arising from the development and evolution of its business.

In February, Xtera Communications announced that Omantel of Oman, a leading wholesale carrier in the Middle East, in partnership with Ethio Telecom, had selected it to build a new submarine cable system. The new Gulf to Africa (G2A) cable system is to be built in partnership with Ethio Telecom, Somalia's Golis Telecom and Telesom Company of the Republic of Somaliland and will connect Salalah in Oman to Bosaso in Puntland and Berbera in Somaliland, with a terrestrial extension on to Addis Ababa in Ethiopia.
