Tested. Trusted. Approved.

Quality is Never an Accident,
It is Always the Result of Intelligent Effort

Testing is the cornerstone of the Approved Networks commitment to our customers, and it goes far beyond mere Interoperability. Our 3-step process tests for functionality, optical compliance, and system compatibility, providing the most complete test model in the industry. Our decades of experience in high-speed optical networking verification allows the world’s largest enterprises, data centers, and service providers to trust our test lab, utilizing it as an invaluable component of their certification process.


Functional, Performance and
Quality of Service Testing

Compatibility and Interoperability Testing

Our state-of-the-art programming and testing facilities host an active test bed of well over 100 servers, switches, routers and NICs. This allows us to confirm full OS and system compatibility and interoperability before shipment, reducing failures and incompatibility in the field.

The Approved Networks onsite development team programs and tests our product lines in almost every modern OEM system, providing unmatched customization, fault isolation and compatibility support using actual customer operating systems.

Our active test bed includes solutions from 100MB up to 400GB and includes systems from almost every major OEM, including: Accedian, Adtran, Adva, Avaya, Arista, Blade Networks, Broadcom, Brocade, Calix, Ciena, Cisco, Dell/Force10, Ericsson, Fujitsu, HPE, IBM, Intel, Juniper, Mellanox, Nokia/Alcatel, Nortel, Overture, Palo Alto, Qlogic and Zhone.

Don't have what you need, or are you looking for a technology the OEMs just don't support? We offer full-service customization for you to achieve your technology needs:

  • Multi-Coded Universal Transceivers
  • Multi-Vendor DACs, AOCs
  • Solutions Not Offered by an OEM
  • Extended Distance Capabilities
  • Private Label Solutions

Combining the test lab with an experienced optical engineering team provides our global customer base with full-service support, including:

  • Full-Service Technical Support Team
  • Experienced Networking and Optical Development Team
  • Geographically Located Field Engineers
  • Category Product Line Managers
  • Dedicated Carrier/Service Provider and Enterprise/Data Center Solutions Architects
  • Service Provider and Data Center specific Sales Engineers

Environmental Testing

The surge in data traffic by the consumer, and the emergence of the connected home (IoT) and 5G, have led to Approved Networks’ optical transceivers being used in more diverse environments than ever. Because networking hardware ages and operates differently when exposed to extreme conditions, Approved Networks tests, confirms and certifies the reliability of our transceivers, DACs and AOCs in our environmental test chamber. That chamber validates the integrity of our components against degradation while it stresses the component in extreme heat and cold, humidity, and other external conditions.
