400Gbps data transmission achieved over DCI in a 75 GHz DWDM channel

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.

WEBINAR: The rise of Edge Data Centers and 400G optics – what will change?

Join this free webinar to learn about the technological drivers for 400G optics and Edge Data Centers, what consequences these new technologies have on optical cabling, what Edge Data Centers are, and how potential connectivity solutions could look like. The webinar will also  address the emerging 400G optical market and the challenges faced on the connectivity end.

Speed race: Just as 400Gb Ethernet gear rolls out, an 800GbE spec is revealed

Just as the stage is set for 400G Ethernet (GbE) to roll out in force later this year, mainly in hyperscale, telco and large data-center networks, there is a call to boost that speed to 800GbE or even higher in the coming years.The need for increased speed in data centers and cloud services speeds is driven by many things including the continued growth of hyperscale networks from players like Google, Amazon and Facebook, but also the more distributed and mobile workloads modern networks support. But the reality on the ground is that much lower speeds are what’s commonly in use.

400GbE-LR8 QSFP-DD compact pluggable interfaces succeed in client-side services trial

Windstream Wholesale and Infinera marked an industry-first with their successful trial of LR8-based 400GbE client-side services. The trial was powered by Infinera’s Groove G30 platform. The trial leveraged Infinera’s commercially available 2x 600G Wavelength muxponder on its Groove (GX) G30 Compact Modular Platform with the CHM-2T sled, which enabled the customer-facing 400GbE service to be transmitted using a single-carrier 600G wavelength.

Fiber Type Matters When Simulating Optical Links and Latency

Simulating real-world fiber optic links and time delays in the lab environment is both a frequent and necessary task for engineers performing R&D and equipment certification testing processes.  With the evolution to more advanced network architecture, increasing speeds of 400G and beyond, and latency always being a key element, replicating the field network as closely as possible in the lab is critical to ensure systems will perform as expected post-deployment. 

Nokia boasts of 1.52 Tbit/s over single mode fiber

Nokia said it recorded speeds four times above the market’s current standard of 400 Gbit/s over fiber, transmitting at 1.52 Terabits per second (Tbit/s) over 80 km of standard single mode fiber — the equivalent of simultaneously streaming 1.5 million YouTube videos – which is four times the market’s current state-of-the-art of approximately 400 Gigabits per second.
