Accounting Policies [Abstract]
Risks and Uncertainties in Entity's Business	The COVID-19 pandemic has had global economic impacts including disrupting global supply chains and creating market volatility. The extent of the recent pandemic and its ongoing impact on our operations is volatile but is being monitored closely by our management. While certain of our European factories were closed during portions of the first half of 2020 due to government actions and local conditions, all were open by May and throughout the remainder of the year. Any further closures that may be imposed on us could impact our results for 2021. Incremental costs we have incurred related to COVID-19, such as personal protective equipment, increased cleaning and sanitizing of our facilities, and other such items, have not been material to date. At this time, we have not identified any significant decrease in long-term customer demand for our products and services. Certain of our customers’ projects and deployments have shifted into 2021 and beyond.

The extent of the recent pandemic and its ongoing impact on our operations is volatile but is being monitored closely by our management. While certain of our European factories were closed during portions of the first half of 2020 due to government actions and local conditions, all were open by May and throughout the remainder of the year. Any further closures that may be imposed on us could impact our results for 2021. Incremental costs we have incurred related to COVID-19, such as personal protective equipment, increased cleaning and sanitizing of our facilities, and other such items, have not been material to date. At this time, we have not identified any significant decrease in long-term customer demand for our products and services.
