Our quality is unparalleled in the industry. We distinguish ourselves by investing in highly trained technical staff and state-of-the-art test facilities to ensure our customers receive superior quality components. As evidence of our commitment to quality, we provide unique test reports for every item we ship. Products undergo both batch testing and individual testing, subjected to full traffic on the equipment for which they are intended.

To effectively assess the quality of an optical transceiver, extensive knowledge of the PCB (printed circuit board), the components on the PCB, the TOSA (transmitter), and the ROSA (receiver) is essential. In the case of DWDM technology, the TOSA accounts for 70% of the quality equation, making it crucial that these components meet the highest standards. Even a minor 0.2nm shift in the TOSA component due to aging or temperature fluctuations can lead to malfunctioning.

Hence, we rigorously test our CWDM & DWDM optics under fluctuating temperatures for an extended duration, employing an Optical Spectrum Analyzer to ensure precise calibration. Additionally, Solid Optics exclusively collaborates with TOSA suppliers with a proven track record of reliability.

Thanks to our stringent quality control procedures, we confidently offer our customers a lifetime warranty on all our transceivers. Each product we ship is fully guaranteed to function correctly. Consequently, due to our extensive testing and quality control measures, we maintain an RMA (Return Merchandise Authorization) rate of less than 0.01%. Our testing procedures are meticulously designed to virtually eliminate the chance of network failure.

However, should you encounter an issue with any of our products, our technicians will promptly address the matter and, if necessary, provide an advanced replacement unit.




After coding our optics for a specific brand, we prove the compatibility in our test lab.


Optics are tested with full traffic to ensure accurate power budget.


For all CWDM and DWDM optics we ensure the channels are precisely calibrated.


We make sure all of the parameters of the optic are precise internally and on the exterior label.


The optical lenses are inspected  and cleaned.
