The sampling oscilloscope is based on equivalent time sampling and waveform reconstruction technology, enabling higher precision and more cost-effective measurement of high-speed optoelectronic signals. By configuring different filter options, it can support optical eye diagram testing under various data rates.

For the high-speed serial data, the clock information is embedded into the transmitted data stream by data encoding, and the clock information is extracted by clock recovery at the receiver, then the data is sampled according to the recovered clock. Therefore, the clock recovery is crucial for the transmission and reception of high-speed serial signals.

In the PON system, the OLT downstream data is transmitted in broadcast continuous mode, while the ONU upstream data consists of burst-mode data packets sent by multiple user terminals in the time-division multiple access (TDMA) mode. The performance of OLT receiver can be verified only by the burst error analyzer with burst mode.

Bit Error Ratio Tester is an instrument used to test and analyze bit error ratio in digital transmission systems, fiber optic communication systems, and digital microwave communication systems. It performs error detection and alarm monitoring, serving as an essential tool for bit error testing in R&D and production of optical modules/devices.

In recent years, with the adoption of PAM4 in optical module, FEC has been introduced mandatorily. It makes optical module manufacturers need to test MAC layer Traffic in addition to PRBS. Different from the traditional Bit Error Rate Tester, the Network Analyzer supports Ethernet packet test, true FEC analysis based on Ethernet frame and standard 2544 protocol test. It also could be applied to the switches for data traffic test, giving network analyzers a broader range of applications compared to Bit Error Rate Testers.

With the increasing demands of higher data rate, a large number of coherent communication modules based on wavelength-tunable lasers are used in the transmission backbone network thus a optical wavelength are applied for wavelength testing.

Optical power meters, optical switches, and optical attenuators are basic instruments used for optical power measurement, optical path switching, optical power adjustment and other application scenarios in the optical communication systems.

The optoelectronic hybrid ATE is a highly integrated testing platform for optical modules. The hardware platform consolidates a range of instruments, while the software incorporates multiple sub-modules tailored for various test functions. Hardware configurations and software modules can be optimized based on specific testing requirements, significantly reducing R&D costs, enhancing system stability, and accelerating the product launch process. This innovation marks a breakthrough in the optical module testing industry, advancing efficiency, automation, and integration to new levels!
