NeoPhotonics demos 120Gbaud InP-based coherent receiver/modulator

NeoPhotonics has used its Indium Phosphide-based Coherent Receiver and Coherent Modulators, coupled with its Ultra-Narrow Linewidth Tunable Lasers or Distributed Feedback Lasers, to demonstrate 120Gbaud operation in applications ranging from 800G LR transmission to 400G long haul transmission.

The next-generation DSP baud rate will be based on 120+ Gbaud, and potential applications include 800LR (≤10km), 800ZR for DCI (≤100km), 800ZR+ for metro-core (≤1000km), and 400Gb/s ultra-long-haul transmission. 

Demonstrations of this level of performance are reported and listed below, showing that corresponding high-speed optoelectronic components are available today to match the DSP baud rate and to enable pluggable or embedded modules at these data rates.

Using its indium phosphide (InP)-based coherent driver modulator (CDM) and intradyne coherent receiver (ICR) with more than 60GHz-bandwidth, NeoPhotonics has experimentally demonstrated the feasibility of the following transmission systems at 120+ Gbaud:

• Long-haul: 400Gb/s over 1500km standard single-mode fiber EDFA-only transmission system with a superior required OSNR of 16.7dB at OFEC threshold;
• Regional/Metro-core: 800Gb/s (with probabilistic shaping) over 1000km standard single-mode fiber EDFA-only transmission system with a superior required OSNR of 24.3dB at OFEC threshold;
• ZR DCI: 800ZR over a single-span EDFA-based 100km standard single-mode fiber with a superior required OSNR of 25dB at OFEC threshold and a transmitter output power of -6dBm; and
• Unamplified LR: 800LR over an unamplified 10km link with a 9dB link budget, and 800Gb/s “coherent lite” over an unamplified 1km link with a budget of 5.2dB, both using a low-latency FEC with a BER threshold at 4 x 10-3. The latter used self-homodyne coherent detection so as to significantly simplify the DSP and remove wavelength locking between transmitter and local oscillator.

“We are pleased to take this opportunity to highlight the progress we have made in pushing our high-performance indium phosphide integration technologies to even higher speeds and over longer distances to enable new potential applications in cloud and data center applications,” said Tim Jenks, Chairman and CEO of NeoPhotonics. “These 120Gbaud components, coupled with our ultra-narrow linewidth external cavity “nano” tunable laser or our distributed feedback lasers, along with concurrent DSP advances, could enable pluggable modules to operate at 800G for applications within and between datacenters, as well as to extend the speed and reach of embedded telecom systems,” concluded Mr. Jenks.

Nokia and AT&T target 5G uplink with distributed massive MIMO

AT&T is working with Nokia Bell Labs in testing distributed massive MIMO (DmMIMO) to significantly increases uplink capacity and speeds in 5G networks without requiring an overly complex solution. Specifically, Nokia is collaborating with AT&T on the validation of DmMIMO and testing the proof-of-concept technology in the AT&T labs. Bell Labs’s DmMIMO simulations have demonstrated increases in 5G uplink capacity between 60% and 90% compared to similarly configured systems with a single panel. While other techniques come at the expense of downlink capacity, DmMIMO would produce sizable increases in uplink capacity without sacrificing performance.

DmMIMO allows devices to leverage signal propagation to multiple cells or antenna panels in a network when establishing a link, thereby turning noise into a useful signal and increasing the uplink throughput. The data transmission is pieced together from multiple antenna panels and cell sites through distributed baseband processing. The processing load between the cell site radio units and the central processing unit is split in a novel way, reducing the fronthaul capacity to cell sites and hence lowering the cost.

Nishant Batra, Chief Strategy and Technology Officer, Nokia, said: “Addressing uplink speeds is becoming critical as consumers are increasingly becoming content creators as well as content consumers, video conferencing has become a cornerstone of the teleworking era, and many of the applications in the industrial internet of things require higher uplink speeds. When 5G-Advanced networks come online, we will see the network enhanced in multiple dimensions, expanding and extending its capabilities. Even today, with the focus on 5G mid-band spectrum rollouts in the U.S., there are opportunities for technologies like this that can maximize available resources. We feel distributed massive MIMO will be a critical element of networking in the 5G-Advanced era to help meet these demands with significant gains in uplink without a hit to downlink performance. Three decades ago, Bell Labs and AT&T invented MIMO, so it is only fitting that we continue this groundbreaking work together for the next generation of MIMO.”

Andre Fuetsch, Executive Vice President & CTO Network Services, AT&T, said: “AT&T and Nokia have a long history of working together on new network technologies, and I welcome this strategic collaboration for the development of distributed massive MIMO technology. Newer applications in the 5G-Advanced timeframe, such as eXtended Reality (XR), are expected to be more demanding on the uplink compared to regular broadband traffic. Technologies such as distributed massive MIMO show potential to improve uplink capacity in the right scenarios. DmMIMO is also a technology that shows potential for the next generation of wireless networks. Therefore, this strategic technology collaboration with Nokia may help provide learnings with long-term benefits to both companies.”
