Quality Control

Sopto focus on “quality”, which highlights the pertinent best practices and benefits of managing quality as an integrated part of business to build a culture of collaboration and innovation. Sopto provides a complete set of instruments to test optical transceivers, such as the latest version equipments for Cisco, Huawei, 3Com, Finisar, HP, Juniper , Brocade and other major brands, the manufacturing serial BERTs, the digital communication analyzers and the light-wave measurement system with a large selection of modules for monitoring, switching and attenuating the optical signals.

Each transceiver is individually tested and walks through the testing challenges. Our quality control procedures are designed to ensure virtually zero chance of failure in your network. Another very attractive products are the multi-port power meters. All needed is to add a DUT-board, some cabling and a computer. Our quality control procedures are unparalleled in the industry.

Optical transmitter eye diagram,transmitter average output power and the optical receiver sensitivity are key parameters to be measured and documented for all optical transceivers. Our transceiver is individually tested in these key parameters as well as the compatibility,full traffic test,laser color, the stable of the center wavelength and other important parameters. Our quality control is to ensure all the parameters meet required specifications.

Quality Certification


How we deal with our product


We check for compatibility in our test-center for all major brands.

Full traffic test

All optics are tested on full 1G or 10G to ensure quality and distance
