5G means new RAN architectures, densification and more fiber

Because of all the new requirements (e.g,. low latency, more bandwidth), new technologies (e.g. eCPRI) and new line rates (i.e. 10G, 25G) that 5G is imposing on the network, new testing practices must follow suit. Where bad splices or bad connections occurred in the past, 4G networks were quick to forgive, but 5G networks definitely won’t. So, unless thorough 5G testing practices are strictly followed, failure rates on new 5G deployments will increase.

II-VI Incorporated’s 25 Gbps Wavelength-Tunable Transceivers for 5G Fronthaul Earn 2020 Lightwave Innovation Reviews High Score

II‐VI’s 25 Gbps wavelength-tunable transceivers received an Innovation Reviews High Score from Lightwave Magazine. II-VI’s 25 Gbps wavelength-tunable transceivers meet the CPRI 10 standard for 25 Gbps fronthaul links in a standard SFP28 pluggable form factor and over the full industrial temperature range. The transceivers support dense wavelength division multiplexing (DWDM) across the C-band, dramatically increasing transmission capacity per fiber, thus virtually eliminating capacity constraints due to fiber scarcity.

Verizon runs 800 Gbps of data across single wavelength of live fiber

Verizon, in conjunction with Ciena and Juniper Networks, have demonstrated the ability to move 800 Gbps of data on a single wavelength. The successful trial on Verizon’s live fiber network showed equipment interoperability from two different suppliers and the capability to quadruple the typical capacity carried on a wavelength. The test traffic was transmitted between two Juniper Networks QFX 5220 packet platforms across two Ciena 6500 platforms powered by WaveLogic 5 Extreme (WL5e) coherent optics.

Webinar: 5G and Power – Distributed to the Edge

5G promises lightning-fast speeds, no lag time, and increased densities — a critical piece to make autonomous vehicles and smart cities a reality. So, why aren’t cars driving themselves yet? The answer is that even though the technology needed to transmit the data exists, there’s not enough power to get it there. Integrating distributed power to high-speed communications and IT nodes seems like a logical fix to the problem. This is valid in concept, but not so easy to implement. Because distributed power combines multiple renewable sources to provide flexible, efficient electricity, it can be somewhat difficult to match generation and consumption.
