NeoPhotonics Corporation (NYSE: NPTN), a developer manufacturer of silicon photonics and advanced hybrid photonic integrated circuit-based lasers, modules and subsystems for bandwidth-intensive, high speed communications networks, has announced that it has completed experimental verification of the transmission of 400Gbps data over data center interconnect (DCI) ZR distances in a 75 GHz spaced Dense Wavelength Division Multiplexing (DWDM) channel, the company said.
NeoPhotonics achieved two milestones using its interoperable pluggable 400ZR coherent modules and its specially designed athermal arrayed waveguide grating (AWG) multiplexers (MUX) and de-multiplexers (DMUX).
First, data rate per channel increases from today´s non-interoperable 100Gbps direct-detect transceivers to 400Gbps interoperable coherent 400ZR modules. Second, the current DWDM infrastructure can be increased from 32 channels of 100 GHz-spaced DWDM signals to 64 channels of 75 GHz-spaced DWDM signals. The total DCI fiber capacity can thus be increased from 3.2 Tb/s (100Gb/s/ch. x 40 ch.) to 25.6 Tb/s (400Gb/s/ch. x 64 ch.), which is a total capacity increase of 800 percent.
NeoPhotonics is a developer and manufacturer of lasers and optoelectronic solutions that transmit, receive and switch high-speed digital optical signals for Cloud and hyper-scale data center Internet content provider and telecom networks. The Company´s products enable cost-effective, high-speed over distance data transmission and efficient allocation of bandwidth in optical networks.
