Data Center Site Selection

Identifying a new location for a data center is not only a critical decision, it can have extreme consequences for all departments. Having a process in place for the site selection team is imperative for success. The process should be viewed as the foundation of every project and every team will build off it.

Cabling best practices with immersion cooling

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.

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.

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.

Simplifying Data Center Network Design with Universal POLARITY Fiber Cassettes

Polarity means that a fiber optic link’s transmit signal at one end of the cable must match the corresponding receiver at the other end. While this concept might seem simple, it becomes more complex with multifiber cables and MPO connectors. Leviton’s new Universal Polarity Fiber Cassettes that help data center managers simplify things even further. The Base12 cassettes allow for the same interchangeable cassette on both ends of a Method B trunk in a fiber channel, reducing the complexity of a fiber network, ensuring consistent polarity, and streamlining network deployment.
