Marvell intros low power, multi-mode 400G DSP

Marvell announced sampling of is new Deneb ultra-low power, multi-mode 400G DSP for disaggregated optical platforms. 

The new 7nm CDSP for 400G pluggable, which is compatible with its predecessor (Canopus), provides a seamless upgrade to interoperable pluggables across multiple platforms. Deneb can be used to enable standards based ITU, Open ROADM and OpenZR+ compliant 100G/200G/300G/400G pluggable transceivers.

"Standards-based interoperable CDSPs will be critical to fuel the growth in coherent pluggables that are expected to address the majority of transport applications," said Pranay Aiya, AVP Product Marketing and Customer Applications at Marvell. "Deneb enables our partners to seamlessly augment their Canopus CDSP based solutions with standards-based technology and expand their addressable market with minimal investment."

XKL announces 400G transponder systems

XKL announced a 400G transponder system.

With an additional XKL DMD (Mux/Demux), XKL's 400G has demonstrated a capacity of up to 4.8 Terabit (Tb) within a single 1U for the DQT400, another 1U for the DMD, or up to 19.2 Tb of available capacity when stacking four 400G systems through the additional DMD device. 

XKL is expecting to initially release a four (4) port configuration in September 2021, with the 12 port configuration expected shortly after.

Bell Canada activates 400G wavelength service

 Bell Canada launched a commercial 400G wavelength service powered by Ciena's WaveLogic 5 Extreme technology.

The 400G service is now deployed across major spans of Bell's 17,000 km fiber infrastructure. Bell plans to expand the service across Canada in the coming months.

"Bell 400G wavelength service efficiently delivers the speed and capacity necessary to meet the fast-growing demand of bandwidth-intensive operators moving massive amounts of data and content to the cloud," said Ivan Mihaljevic, Senior Vice President, Wholesale at Bell Canada. "Bell's unparalleled network infrastructure and customer support, coupled with Ciena's market-leading optical wavelength technology, offers major operators here in Canada and internationally the opportunity to scale up easily, efficiently and sustainably with our highly energy efficient 400G capabilities."

"The global shift to 400G is happening and Bell Canada is leading the way by evolving its network to support the insatiable and often unpredictable network demand driven by the cloud, streaming video and more," said Bruce Hembree, Vice President and General Manager for the Americas at Ciena. "With WaveLogic 5 Extreme, Bell can offer new, high bandwidth 400G services to carrier and content provider customers between key points of presence across Canada and into the US."

Keysight debuts 400GE test system covering PAM4 and 100GE NRZ

Keysight Technologies introduced its new AresONE-S 400GE test system for validating complex, mixed 400 gigabit Ethernet (GE) and lower-speed networks and devices.

The AresONE-S 400GE test system, which is aimed at network equipment manufacturers and data center operators, provides 6.4 Tbps load and stress traffic to detect and debug data transmission errors at multiple Ethernet speeds. Further, AresONE-S allows multiple systems to be synchronized together to test 25.6 Tbps networking devices and equipment using a single test system.

Highlights of Keysight’s AresONE-S test system:

  • An ultra-high-density, 2 rack unit (RU) fixed chassis to deliver optimal rack space footprint.
  • The IxNetwork software application, a Layer 2 and 3 protocol emulation platform that runs end-to-end tests with an extensive list of networking protocols and data plane traffic to test network infrastructure performance.
  • A single test platform for all seven 400GE PAM4 and 100GE NRZ speeds: 400/200/100/50GE PAM4 and 100/50/40/25/10GE NRZ to test all speeds and FEC methods to future-proof investments.

AresONE-S fixed chassis is available in two options, the AresONE-S-400GE QSFP-DD High-Density 16-Port Test System and AresONE-S-400GE QSFP-DD High-Density 8-Port Test System. Customers can start lower-port-count testing by purchasing 4 ports in the 8-port chassis, or 8-ports in the 16-port chassis. Keysight’s “pay-as-you-grow” model enables customers to add ports and software options in the field to support future test requirements.

Data center operators have widely deployed mature 100GE non-return-to-zero (NRZ)-based technologies.  Keysight notes that higher Ethernet speeds, such as 400GE, create new mixed signaling and forward error correction (FEC) implementations in data center networks, as well as multi-rate speed environments. The transition from NRZ to pulse amplitude modulation level-4 (PAM4) requires testing of both types of encoding.

“Data center operators are dealing with complex environments containing multiple signaling technologies and Ethernet speeds that continue to evolve,” said Ram Periakaruppan, vice president and general manager, Keysight’s Network Test and Security Solutions group. “AresONE-S doubles the port density of any other 400GE test platform and delivers the flexibility our customers need to verify their networks and network equipment, while scaling to meet future requirements.”
