Transceivers for testing networks and adapting to device changes
First Claim
1. A test transceiver comprising:
- at least one of a receive optical subassembly (“
ROSA”
) or a transmit optical subassembly (“
TOSA”
); and
a controller, wherein the test transceiver is configured to;
introduce a predetermined transceiver performance error into an optical network;
control operation of the ROSA;
control operation of the TOSA; and
control out of band signaling with other network devices to allow the test transceiver to correct problems that the test transceiver detects on the optical network.

Abstract
Test transceivers are disclosed for testing optical networks. The test transceivers generate one or more errors on a network in a specific, reproducible way, thereby enabling a tester to easily and readily identify whether network devices are operating properly, or prone to failure. A corrective transceiver is also disclosed. The corrective transceiver is configured to continually detect operating parameters of one or more network devices in a network. The corrective transceiver can identify the operating parameters through out-of-band communication with the one or more network devices. The corrective transceiver is further configured with one or more instructions to adjust its own operating parameters to re-sync with another network device as necessary to continue network communications during a failure of the network device.
