JUNE 10, 2009 -- Subisu CableNet Pvt. Ltd., a service provider in Nepal, has launched a major network expansion throughout the country using optical transport equipment from Ekinops (search Lightwave for Ekinops), a provider of next-generation multiprotocol, multireach optical transport and aggregation technologies for metro, regional, and long-haul networks.
The Subisu installation has transformed the company from a primarily Kathmandu-based cable provider and ISP to a national, multicity provider of enterprise and transport services.
Subisu was seeking cost-effective DWDM technology for its expanded network, along with the ability to support multiple protocols, including Gigabit Ethernet, STM-1, STM-4, and STM-16. The Ekinops 360 features DynaMux (dynamic multiplexing) capability, which allows any mix of protocols to be multiplexed over a single wavelength or transport service. The platform also features flexible add/drop capabilities which Subisu says will allow it to better serve customers throughout the country.
The new Subisu optical network, which features regional DWDM, multiprotocol aggregation, and transport over optical fiber. Currently, the network links five cities via four segments and Subisu has plans to expand the network to additional cities later this year.
Binaya Saud, chief planning officer for Subisu, says the compact Ekinops 360 platform allows Subisu to deliver Layer 2 Ethernet and MPLS services for enterprise customers as well as SDH and wavelength services for carrier customers.
"Ekinops was very good at advising us on a cost-effective, flexible, and power-efficient design that addresses both our immediate needs and our future expansion," Saud says. "The Ekinops solution clearly delivered the lowest total cost of ownership of all the vendors we considered for this major project."
Advantages that Subisu considered with the Ekinops platform include flexible support for all Subisu services and the ability to accommodate DWDM, CWDM, and 1,310-nm capability on the same platform. Power efficiency was also a consideration, for a nation where power is a serious issue. The T-Chip (Transport on a Chip) design of the Ekinops 360, with all the optical transport intelligence on a single chip, keeps the power needs as low as possible for Subisu, according to the technology supplier.
