Tested. Trusted. Approved.

Quality is never an accident;
it is always the result of intelligent effort

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

Performance, Functional and
Quality of Service Testing

Approved certifies performance and functionality of all our transceivers, DACs and AOCs. Beginning with a rigorous supply chain qualification process, which includes preliminary, sampling and production throughput and compliance testing. Approved Test Labs on both coasts provide comprehensive testing up to 400G, including:

  • BER Testing
  • Latency Validation Testing
  • Throughput testing to IEEE 802.3bs standard
  • RFC2544
  • ITU-TY.1564
  • Activation Testing
  • QoS Testing
Ber VSAM RFC2544 Test


Optical Compliance, Characterization
and Validation Testing

Our fully automated optical transmitter and receiver testing process supports optical transceiver characterization, supplier validation, failure analysis and pass/fail determination. This includes stringent compliance test reporting of:

  • Eye diagram/mask margin
  • Eye width, eye height, rise/fall time
  • Eye contour
  • Bathtub curve
  • Rx sensitivity waterfall curve: BER vs ROP, BER vs OMA

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.

Approved’s 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 OS and 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.

Environmental Testing

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