OFC/NFOEC Features Breakthroughs In Network Communication

Show Room

The OFC/NFOEC convened in mid-March to feature at least three breakthroughs in Network Communication, its website said.

The Optical Fiber Communication Conference and Exposition/National Fiber Optic Engineers Conference gathered tech experts, computer engineers, telecom giants and leaders in datacom and computing to present a power-saving ultra-high-speed optical communications link, a new record for 400GB/s data transmission and a new automated process that simplifies the alignment and splicing of multicore optical fibers.

The event is a premier conference wherein researchers and experts are given the time to present their results, experiences and insights on a host of topics such as cloud computing and datacenter networking, among others.

Ultra High-Speed Optical Communications Link

A team of IBM researchers has finally found a way to transmit huge amounts of data with low power consumption. This means that supercomputers operating at a speed 100 times faster than our current system may finally be coming to reality.

The research, funded by the US Defense Advanced Research Projects Agency, broke the previous power-efficiency record set by OFC/NFOEC.

Jonathan Proesel, one of the researchers, said that computer systems may finally reach the level of “exascale computers.” But to do this by the year 2020, there is still a lot more work needed to be done. This new prototype optical link will be beneficial for reaching the point of the exascale mark, which requires an energy-efficient transmission of a massive amount of data.

400GB/s Data Transmission Over 100 Gigahertz-Grid Optical Networks

An AT&T team is currently waiting for the patent for a technique they devised in which 400GB/s data transmission will be possible over 100 gigahertz-grip optical networks over ultra-long distances. This came even amid a study being made about making standard Ethernet transmission speeds of 400GB/s or 1TB/s.

The said technique enables the tuning of the modulation spectral efficiency. The system will also generate Nyquist-shaped 400GB/s signals with tunable spectral efficiency using only modulated subcarriers. Also, eight 100GHz-spaced, 400GB/s wavelength-division-multiplexed signals were combined and then transmitted using 100-km fiber spans.

As a result, the AT&T team was able to send the signals over 12,000 kilometers. The previous record was at 9,000 kilometers.

New Automated Process to Simplify Alignment and Splicing of Multicore Optical Fibers

Multiple optical fibers have more signal-carrying capacity than the usual single core fibers. However, because of the difficulty in aligning and splicing them, not many Network Communication companies use them. But during the OFC/NFOEC, a new technique was introduced.

Instead of manually aligning and splicing the multicore optical fibers (like many companies do), the automated process will make sure they are done right with minimal or no change in signal quality.

Wenxin Zheng, manager of splice engineering at AFL, said in a statement that the manual alignment and splicing of multicore optical fibers are only good for research. When it comes to using multicore fibers in factoring and in production, automated is the only way to do it.

This process will apparently use Fujikura FSM-100P+ fusion splicer to align and splice multicore fibers using a pattern-matching algorithm.

The OFC/NFOEC has truly presented breakthroughs in network communications that will surely alter the course of technology in the next few years. Faster data processing, power-saving transmission of files and the ability of multicore optical fibers to be used by telecommunication companies—these are just some of the innovations that will benefit the next generations.
