Conflict minerals

Ciena supports efforts to eliminate the use of tantalum, tin, gold, and tungsten obtained from sources that directly or indirectly finance or benefit armed groups in the Democratic Republic of the Congo or an adjoining country.

Ciena has requested its suppliers of components that may contain tantalum, tin, gold, or tungsten to submit sourcing information using the questionnaire developed by the RBA and Global eSustainability Initiative (GeSI) working group. Ciena expects its suppliers to take similar measures with their own suppliers to reasonably assure responsible sourcing throughout the supply chain. More details can be found on Ciena’s latest conflict minerals statement and Conflict Minerals Reporting Template.
