Yes, provided each transceiver is compatible with its local host and both modules use matching optical standards, wavelengths, data rates, fiber types, and other required link parameters.

Yes. Host compatibility and optical-link compatibility are separate issues. A module may be correctly recognized while the link fails because of fiber, wavelength, FEC, polarity, configuration, or link-budget problems.

The device may reject the module, display an unsupported-transceiver warning, fail to establish a link, or provide incomplete monitoring information.

Abnormal temperature, voltage, TX power, RX power, or bias-current readings may indicate an optical or hardware issue, but they can also result from incorrect calibration or communication between the compatible module and host device.

Compatibility coding itself does not determine transmission distance. Reach is primarily determined by the optical specification, fiber type, wavelength, link loss, connector quality, and network design.
