Powerful 800G testing with real traffic

EXFO’s BA-4000-L2 is a combined layer 1 BER tester and Ethernet (L2) traffic analyzer for 800G transceivers, including 800G DR4/FR4/LR4, DCO and LPO transceivers. The solution includes FEC testing (including FEC statistics), burst error detection and BER calculated from host to end for the industry’s most reliable measure of error when testing optical transceivers, including LPO devices.

Superior hardware design

Native electrical interface

Excellent signal quality

Clean eye diagram

Low error floor

Powerful equalizer and channel simulator is ideal for LPO testing

With LPO transceivers, no DSP is present to precondition or equalize the electrical signal, as is done in retimed optics. Therefore, any change in signal integrity on the host side is reflected onto the optical side and the more times the signal is handed off, the more potential for introduction of bit errors. Traditional transceiver testing techniques can’t pick up this signal degradation so new, more powerful testing techniques are required. The BA-4000-L2 detects the presence of reflection, intersymbol interference (ISI) and FEC tail instability which are key performance indicators, capturing the presence of errors. Learn more.

Segmented FEC (DCO) and concatenated FEC (200G/lanes) architectures require L2 framed traffic

In the latest generation of optics and transceivers, the forward error correction (FEC) encoding and decoding function is moving from the host side to within the optical transceiver. With this evolution in functionality, transceivers are no longer agnostic electrical-to-optical converters and therefore FEC testing is required for applicable transceivers. The BA-4000-L2 delivers a layer 2 framed signal to validate DCO and 200G per lane optical transceivers.
