Ranovus developing DWDM links for the data centre

Ranovus has raised US $11 million in funding to develop Terabit capacity links for the data centre. The Ottawa-based start-up plans to use dense wavelength-division multiplexing (DWDM) technology to create huge data pipes that reduce significantly the power consumption, and cost, per bit.

Cisco Systems' 100 Gigabit spans metro to ultra long-haul 

Cisco Systems has demonstrated 100 Gigabit transmission over a 3,000km span. The coherent-based system uses a single carrier in a 50GHz channel to transmit at 100 Gigabit-per-second (Gbps). According to Cisco, no Raman amplification or signal regeneration is needed to achieve the 3,000km reach.

Feature: Beyond 100G - Part 2


"The days of a single modulation scheme on a part are probably going to come to an end in the next two to three years"

MultiPhy eyes 40 and 100 Gigabit direct-detect and coherent schemes 

Visiting Israeli start-up MultiPhy at its office in Ness Ziona, near Rehovot, involves dancing around boxes. “We are about to move,” apologises Ronen Weinberg, director of product management at MultiPhy. But the company will not have to travel far. It is crossing buildings in the same Ness Ziona Science Park, moving in next to Finisar’s Israeli headquarters.

Cisco Systems' coherent power move

Cisco Systems’ acquisition of CoreOptics means the company has largely cornered the coherent market, says Telecom Pragmatics. 

Cisco Systems announced its intent to acquire the optical transmission specialist CoreOptics back in May. CoreOptics has digital signal processing expertise used to enhance high-speed long-haul dense wavelength division multiplexing (DWDM) optical transmission. Cisco’s acquisition values the German company at US $99m.


"Let me be clear, we don’t believe 100Gbps serial will dominate the market for a long time, or 40Gbps for that matter"

Mark Lutkowitz, Telecom Pragmatics
