Traffic Testing

All transceivers undergo bit error rate (BER) and packet loss testing to guarantee zero data loss and full compliance with Ethernet and Fibre Channel standards.

Optical Performance Validation
Optical Performance Validation

Our modules are evaluated for signal integrity, eye diagram clarity, and BER, ensuring stable, high-quality optical transmission in all operating conditions.

End Face Inspection
End Face Inspection

Each module's fiber interface is inspected and cleaned to eliminate contamination and physical defects -- a critical step for optimal signal performance and long service life.

Warranty & Compatibility

All of our transceivers come with a limited lifetime warranty and are fully tested for performance, reliability, and interoperability.

Zero Risk
Zero Risk

Using our transceivers does not void the warranty of your network equipment. Global OEM policies and consumer protection laws (like the Magnuson-Moss Warranty Act) prevent manufacturers from denying support based solely on the use of third-party components.

Guaranteed Compatibility
Guaranteed Compatibility

Our modules are coded and tested for seamless operation across major platforms including Cisco, Arista, Juniper, HPE, Nvidia, Huawei, and more. This rigorous validation ensures plug-and-play reliability and full compliance with OEM specifications.

Q&A

Commonly asked questions

No. Under the Magnuson-Moss Warranty Act and similar global consumer protection laws, OEMs cannot void your equipment warranty simply because you use a third-party transceiver. Your equipment warranty remains intact.

Yes. Our transceivers are manufactured to the same MSA standards as OEM modules. They undergo rigorous testing for optical performance, thermal stability, and compatibility before shipping.

Yes. Our modules are coded for the specific platform you select at purchase. They are recognized natively by the switch OS without any additional configuration or commands.

No. Our transceivers meet the same IEEE and MSA specifications as OEM modules. They deliver identical optical performance, data rates, and reach characteristics.

Yes. We offer full support, RMA service, and warranty coverage on all modules.
