TelOne turns to Tejas for capacity expansion

India-headquartered networking product company Tejas Networks has announced that TelOne, one of Zimbabwe’s major operators, has deployed the Tejas 100G/100G+ coherent dense wavelength division multiplexing (DWDM) solution.

TelOne has the widest network coverage in Zimbabwe, with connectivity across the country anchored on what it calls its robust backbone infrastructure. TelOne has strong connections to multiple undersea cable systems and has a shareholding in the West Indian Ocean Cable Company (WIOCC), which has a major stake in the East African Submarine System (EASSy) cable.

As Tejas explains, DWDM enables multiple optical wavelengths to be ‘multiplexed’ (that is, combined) on a single fibre strand and thereby conserves expensive fibre reserves. While initial DWDM systems were typically limited to carrying 2.5Gbps of bandwidth per wavelength, recent advances in coherent DWDM technology can deliver 100G and 100G+ (greater-than-100G) bit rates per wavelength over longer distances at the lowest cost per bit.

Tejas’ 100G DWDM/OTN solution was selected by TelOne after a competitive bidding process and a successful field trial. Tejas was able to successfully demonstrate high-speed transmission of multiple 100G lambdas while meeting the stringent performance and reliability requirements in a cost-effective manner. 

Mr Sanjay Nayak, CEO and MD of Tejas Networks, pointed out that the solution empowers customers to diversify their existing DWDM vendor base and to use what Tejas calls its proven, cost-effective solution to expand and inter-operate.

Mrs Chipo Mtasa, Managing Director at TelOne, added, “TelOne offers access to a vast network footprint in Zimbabwe. With rising demand for bandwidth and higher speeds from our customers, we were looking for a versatile solution that could significantly expand the capacity on our existing fibre network with incremental investments.”
