Loopback modes are specialized confi gurations of the transceiver datapath where the traffic stream is folded back to the source. Typically, a specific traffic pattern is transmitted and then compared to check for errors. Loopback test modes fall into two broad categories:
• Near-end loopback mode loop transmits data back in the transceiver closest to the traffic generator.
• Far-end loopback mode loop received data back in the transceiver at the far end of the link.
Loopback testing can be used either during development or in deployed equipment for fault isolation. The traffic patterns used can be either application traffic patterns or specialized pseudorandom bit sequences. Each transceiver has a built-in PRBS generator and checker.
