Power and wavelength testing
Test the signal transmission strength and wavelength, ensure the signal decoding capability of the receiver, and maintain consistency in wavelength from the transmitter to the receiver.
Test the bit error rate and packet loss rate, to make them meet the corresponding standards and ensure the performance of transceivers.
Optical Performance Testing
Test the transceivers' eye diagram situation, receiving sensitivity, extinction ratio, wavelength, light-emitting, light-receiving, current and voltage, to ensure the signal quality, stability and reliability of the transmission.
End Face Testing
Check the end face of the transceivers and keep them clean for more stable data transmission, better performance, and durability.
Various Switch Tests
Every module is quality tested for compatibility in the multi-brand switches environment, guaranteeing flawless operations.
