Welcome To Twentsche (Nanjing) Fibre Optics Ltd. (for short: TFO)!
In November 2020, TFO completed the new version of ISO45001 Occupational Health and Safety Management System by passing the third-party certification audit after the previous ISO45001 version transfer successfully. At the same time, we also applied for the synchronous certification of IQNet International Certification Alliance. This certificate has high credibility both in China and abroad due to its high evaluation level. IQNet certificate is not only a passport to enter the international market, but also a symbol of the company's own image publicity and honor.
