The 400G optical module is mainly used for photoelectric conversion. The electrical signal is converted into an optical signal at the transmitting end, and then transmitted through optical fiber. At the receiving end, the optical signal is converted into an electrical signal.

The Double 85 Test is an environmental stress acceleration test typically conducted at a temperature of 85 ℃ and a humidity of 85% RH. This type of test is mainly used to evaluate the performance and stability of products in high temperature and high humidity environments.

By using SLT to perform functional testing on the test chip in a simulated terminal environment, equipment manufacturers can prevent missed detection faults that are difficult to detect using traditional wafer and packaging testing techniques.

HAST testing is a testing method used to evaluate the reliability and lifespan of products under high temperature, high humidity, and high pressure conditions.

System level testing (SLT) refers to testing the device under test (DUT) in simulated terminal usage scenarios

Chip HAST testing is a testing method used to evaluate the reliability and lifespan of products under high temperature, high humidity, and high pressure conditions.

The ZONGLEN heat flow meter is compatible with various brands of optical testing equipment on the market, and can complete optical performance testing in high and low temperature environments. It is an essential component of optical testing equipment

Common non constant stress spectra and combined stresses include: step stress tests; Progressive stress test; High Acceleration Life Test (HALT) (equipment level); High Acceleration Stress Screening (HASS) (equipment level); High Acceleration Temperature and Humidity Stress Test (HAST) (Part Level).
