Kyoto Semiconductor develops high-speed photodiode with 400Gbps transmission speed

Kyoto Semiconductor has developed a high-speed photodiode KP-H KPDEH12L-CC1C to support 400Gbps transmission systems that use PAM4 (Pulse Amplitude Modulation 4) inside and between data centers. With the introduction of this InGaAs photodiode, the company is continually supporting the increasing speeds and capacity requirements for transmission systems in 5G networks and beyond. Mass production will start in November, 2020.

How To Survive the Coronavirus and Thrive

Data centers remain crucial to businesses’ survival during the pandemic. As more companies transition into remote work, their use of cloud services has skyrocketed. This rapid adoption wouldn’t be possible without the versatility and provision of data centers. Cloud usage aside, internet traffic has increased as a whole, putting more pressure on data centers. Without a reliable network, much of life in quarantine wouldn’t be possible. If data centers weren’t as robust as they are, this heightened traffic could have meant disaster.

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.

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.

Taking fiber to the edge: Innovating simpler, but faster optical links to connect the edge cloud

The move to edge cloud is resulting in a huge proliferation of local data centers. By moving processing power and services closer to the edge of the network, a wealth of new cloud-based applications dependent on low latencies and highly reliable connections emerge. Like their centralized counterparts, edge data centers need high capacity like long-haul transport links, but the networks they’re building are fundamentally different. Instead of a connecting a few distant central data centers, cloud providers are connecting dozens of distributed data centers in a single city in order meet the fast response times and low latencies required of new edge computing services.
