Cabling best practices with immersion cooling

By on • ( Leave a comment )

Exactly how do data center owners and operators manage their cabling when their servers are immersed in liquid coolant?
Immersion cooling manufacturers understand the need for cable management when designing their cooling racks. Because the servers themselves are completely immersed, the cable connections are also made under the surface of the coolant. While the liquid used to cool sensitive IT equipment is non-conductive and non-flammable, it can damage certain types of cabling. Some PVC cable jackets stiffen over time from being immersed in the liquid coolant. Data center operators may choose to continue to use low-cost cabling with PVC jackets, like Ethernet cables, and simply swap them out when they stiffen. Otherwise, it’s best to use cables with synthetic rubber cladding, which the liquid coolant does not affect.

From social safety nets to building technology, COVID-19 has forced us to notice a lot of the failings of things we take for granted. Smart building technology needs to expand and improve in order to help keep tenants and residents safe and comfortable in a post-pandemic society. Here are some of the ways that smart technology and tech policies can grow to fill these newly-uncovered needs: Supply chains and cybersecurity; at home risk management; smart disinfection; distributed energy systems & disaster preparedness; and social distancing & emissions.

Connected buildings offer great opportunities for the wellbeing and satisfaction of the building’s users. A great example of a human-centric approach to smart building solution is TietoEVRY Empathic Building, where the entire IoT service is built around creating the best possible working environment. The employee satisfaction over their working environment is known to ripple down to better work efficiency, motivation and fewer sick leaves. Measuring the temperature, CO2 levels and humidity are just some of the ways smart buildings can help in creating a better work environment or customer experience.

5G is billed as the connectivity fabric that will support a new era of consumer and enterprise experiences. But, in the context of smart buildings, 5G is part of a larger equation that also encompasses artificial intelligence and the internet of things. The combination of the three–5G, AI and IoT–will allow for real-time data collection and analysis that will make buildings more efficient and more user-friendly. Building owners with a robust technology strategy will be able to leverage these rapidly developing solution sets to reduce net operating expense while leveraging the technologies to drive up lease rates by providing new services.  

How to Splice Rollable Ribbon in the Data Center

Adapting to new advancements in fiber optics – like rollable ribbon – does not have to be complicated. In this blog, Mike Cooper explains how deploying rollable ribbon can be an effective method of saving space. In data centers where fiber optic cables are starting to fill pathways, deploying rollable ribbon can be an effective method of saving space. It is also flexible, like a distribution cable, making it more durable and less susceptible to breaks. Moreover, rollable ribbon splices just like matrix – 12 fibers at a time.

With the increase in Advanced Driver-Assistance Systems (ADAS), and the industry looking at autonomous vehicles on the horizon, the intelligent car needs growing bitrates to flow through its nervous system. The protocol of choice to implement the communication infrastructure in the car is Ethernet, and the 802.3 Working Group of the IEEE standardization organization is already paving the way to have multi-gigabit per second optical Ethernet in vehicles. A dedicated Study Group is already working on the future IEEE 802.3cz standard.

400Gbps data transmission achieved over DCI in a 75 GHz DWDM channel

NeoPhotonics achieved two milestones using its interoperable pluggable 400ZR coherent modules and its specially designed athermal arrayed waveguide grating (AWG) multiplexers (MUX) and de-multiplexers (DMUX). First, data rate per channel increases from today’s non-interoperable 100Gbps direct-detect transceivers to 400Gbps interoperable coherent 400ZR modules.Second, the current DWDM infrastructure can be increased from 32 channels of 100 GHz-spaced DWDM signals to 64 channels of 75 GHz-spaced DWDM signals.
