400G transceivers deliver 32Tbits per fibre

NeoPhotonics Has shipped its first  400G capable ClearLight CFP2-DCO transceivers for end customer trials.The transceivers deliver 32Tbits  per fiber – significantly higher than today’s 200G CFP2-DCO capacity or the emerging 400G CFP2-DCO capacity– by using internal optics that can support 80 channels of 64 Gbaud data at 75 GHz wavelength channel spacing.

Webinar: Minimizing Fiber Cable Plant ‘Angst’ when Migrating from 10G thru 400G

To achieve successful migration to 40 or 100-200-400 Gb, it is important to consider the fiber/transceiver options and cost implications (particularly the cost of managing high volumes of fiber cable on distribution frames and in pathways). During this webinar will show the advantages of a high-performance MM fiber coupled with BiDi transceivers as a cost effective migration option that proves very practical in minimizing fiber distribution element ‘sprawl’ and assuring that cable pathways are manageable.

The challenges of migrating optical networks to 400G

While 400G is the answer to increasing data demands, there will be an initial struggle on the network backbone in supporting these initiatives and fulfilling the promise of higher-capacity transport. 400G is not a natural extension to existing network infrastructure, and requires taking into account new restrictions and a redesign of the optical network infrastructure. 400G capacity over a single wavelength with its high baud rate is simply too spectrally wide to pass through the 50-GHz filters and fixed grid ROADMs (reconfigurable optical add-drop multiplexers). A new “runway” is required to reap the benefits of this new technology.

Ethernet Alliance wrapping up latest High-Speed Networking Interop Plugfest

18 companies participated testing optical transceiver, #Ethernet switching equipment, and T&M (physical layer and protocol analysis) products at the Ethernet Alliance’s latest High Speed Networking (HSN) Plugfest  at the University of New Hampshire InterOperability Laboratory (UNH-IOL). This was the fourth event to provide participants with the ability to test the interoperability of their products for applications from 25 Gigabit Ethernet to 400 Gigabit Ethernet (GbE). The HSN Plugfest drew a greater number of companies than the previous iteration, including some who joined the Ethernet Alliance just so that they could participate.
 

Applications Beyond 100G – 1265166

Trailblazing network operators including service providers and hyperscale data centers are pushing transmission speeds up to 400 Gbits/sec. While these few users are facing the headwinds that challenge early adopters, they also are paving a path for future network owner/operators, who will benefit from the standards and technical developments that will enable widespread deployment of greater-than-100G speeds. This webcast seminar examines the roadmap to speeds beyond 100G, discussing the options that currently exist and that are emerging for future adopters. The seminar provides an opportunity for users that are pushing 100G speeds today to learn and plan for their next generations of network upgrades.

Know Your 400G Ethernet Options!

In 2017, the IEEE-SA Standards Board approved IEEE Standard 802.3bs. This resulted in the official launch of 400 Gigabit Ethernet. In theoretical terms, it is the advancement from 100G Ethernet and can operate four times faster than 100G. Not only is this, but it also offers a denser configuration and a better economy of scale. Unlike 100G transceiver modules, the 400G transceivers come with 8 channels and utilize PAM4 encoding to accomplish 50Gbps per channel.

From 400G Field Testers to 800G Lab Validation: VIAVI To Unveil Advanced Solutions at ECOC 2019

VIAVI is introducing new solutions at ECOC including: The T-BERD/MTS 400G Network Tester, which provides rate integration spanning from 400GE down to T1/E1 in addition to fiber optic testing using OTDRs and WD  Channel Checkers along with interfaces such as QSFP-DD and SFP-DD. The MAP-300 photonic metrology and test automation platform delivers the precision required for laboratory testing, combined with configurability to meet the demands of the manufacturing process. Remote automation functionality, along with multi-user architecture, helps increase capital utilization and dramatically reduce the cost of testing.The modular OTU-8000 Optical Test Unit with a tunable DWDM OTDR and the ultra-compact OTU-5000 rack-mounted OTDR  supports rapid, automatic identification of fiber events such as bends, crushes, breaks and malicious tapping. A single optical test head can test hundreds of fiber links, and auto reports the GPS location of a fault within minutes, dramatically reducing the time and cost of construction and repair.
