Combining Layer 1 BER testing and Layer 2 Ethernet traffic analysis for 800G transceivers, including DR4, FR4, LR4, DCO, and LPO types. The solution features FEC testing with detailed statistics, burst error detection, and end-to-end BER calculation—ensuring the industry's most accurate and reliable error measurement for optical transceiver validation, including LPO devices.
A comprehensive solution that delivers Layer 2 framed signals to validate segmented FEC (DCO) and 200G per-lane optical transceivers. Its advanced equalizer and channel simulator make it the perfect tool for LPO testing.
The powerful equalizer and channel simulator is ideal for testing LPO (Linear Pluggable Optics) transceivers. Unlike retimed optics, LPO transceivers do not include DSPs to precondition or equalize electrical signals. As a result, any degradation in signal integrity on the host side is directly transmitted to the optical side. With each signal handoff, the risk of bit errors increases. Traditional transceiver testing methods often fail to detect this type of signal degradation, making advanced testing techniques essential. The BA-4000-L2 addresses this need by detecting key performance indicators such as signal reflection, intersymbol interference (ISI), and FEC tail instability—factors that reveal the presence of bit errors.
