The QLx4300-S45 is a settable quad receive-side equalizer with extended functionality for advanced protocols operating with line rates up to 3.125Gb/s such as InfiniBand (SDR) and 10GBase-CX4. The QLx4300-S45 compensates for the frequency dependent attenuation of copper twin-axial cables, extending the signal reach up to 40m on 24AWG cable.

Features
