    The power consumption is minimal, and the cost savings compared to fiber optic solutions for short-range connections are significant. The only downside is the limited distance, but for our in-rack connections, it's been perfect.

    I have used QSFPTEK products before. Bought twice from their website, both worked fine, engineer communication was excellent and reliable. BTW, their DACs do not include shipping, but are still extremely cheap.
