Powerful equalizer and channel simulator designed 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-RCNC detects the presence of reflection, intersymbol interference (ISI) and FEC tail instability which are key performance indicators, capturing the presence of errors.
