Vietnam Telecoms National (VTN) will deploy Ciena’s coherent 40G optical networking solution to support growing capacity demands on its nationwide optical backbone. VTN, which is an exclusive state-owned subsidiary of Vietnam Post and Telecommunication Group (VNPT), is upgrading an existing network based on 10G links.
Ciena said its 40G solution was selected because of its coherent and electronic dispersion compensation technology, which allows VTN to upgrade its existing 10G national backbone across country sites to 40G with the simple addition of transponder cards and no re-engineering of existing fiber routes or additional equipment required. The solution also provides investment protection as it can easily scale to 100G in the same manner as capacity demands increase.
