Loopbacks for MT interconnect applications are driven by both network systems-solutions providers and the optical-devicecommunity that design and make transceivers or active components. Loopbacks are used primarily as a means to test optical links in networks or devices by “looping back” the connections from the TX (transmit) pairs to the RX (receive) pairs. By doing this, a complete optical link is formed, allowing the optical performance evaluation of a discrete component or a complete link in a network path covering one or more interfaces.
