NeoPhotonics announces general availability of QSFP-DD and OSFP 400ZR coherent modules
NeoPhotonics Corp of San Jose, CA, USA – a vertically integrated designer and manufacturer of silicon photonics and hybrid photonic integrated circuit (PIC)-based lasers, modules and subsystems for high-speed communications – says that its QSFP-DD and OSFP 400ZR pluggable modules are in general availability and shipping to customers.
These products utilize NeoPhotonics’ silicon photonics coherent optical subassembly (COSA) and low-power-consumption, ultra-narrow-linewidth Nano-ITLA tunable laser, combined with the latest generation of 7nm-node DSP (digital signal processing) technology, to provide full 400ZR transmission in a standard data-center QSFP-DD or OSFP form factor that can be plugged directly into switches and routers. This greatly simplifies and cost reduces data-center interconnect (DCI) networks by enabling the elimination of a layer of network equipment and a set of short-reach client-side transceivers, and paves the way for similar benefits in metro networks.
The 400G modules are compliant with the OIF 400ZR Implementation Agreement and are interoperable with other manufacturers’ 400ZR modules that utilize a standard forward error correction (FEC) encoder and decoder. The modules are capable of tuning to and transmitting within 75GHz- or 100GHz-spaced wavelength channels, as specified in the OIF agreement, and operate in 400ZR mode for Cloud DCI applications. For longer metro reaches, the modules are designed to support 400ZR+ modes.
NeoPhotonics’ QSFP-DD and OSFP modules have completed reliability qualification and have passed 2000 hours of high-temperature operating life (HTOL) as well as other critical tests per Telcordia requirements.
NeoPhotonics recently announced that it had used its QSFP-DD coherent pluggable transceiver to transmit at a 400Gbps data rate over a distance of 800km in a 75GHz-spaced DWDM system with more than 3.5dB of optical signal-to-noise ratio (OSNR) margin in the optical signal while remaining within the power consumption envelope of the QSFP-DD module’s power specification.
“This demonstration of high data rates over longer distances shows the potential of these game-changing products, and we expect to see increasing deployment of coherent pluggable modules with different use cases, from data-center interconnect to metro and regional applications as well as 5G wireless backhaul,” says chairman & CEO Tim Jenks. “Since the beginning of coherent transmission, NeoPhotonics has been at the forefront in meeting the volume needs of our customers, as is indicated by our recent announcement that we had shipped a cumulative total of more than 2 million ultra-narrow-linewidth tunable lasers.”
