1.25 Gb/s SR SFP TX TRANSCEIVER PR4DU22K

PR4DU22K is a 1.25 Gb/s SR SFP TX transceiver. Select it only after confirming that the host equipment and the opposite end of the link specify this exact module or matching documented parameters. The listing does not provide wavelength, optical connector, supported fiber type, reach, receiver pairing, power budget or temperature limits, so verify every one of those items in the manufacturer documentation. Do not treat the 1.25 Gb/s rate and SR label as sufficient compatibility evidence. Record the host port, remote endpoint, fiber route and selected module code in the network design. Before installation, check the documented handling, insertion and cleaning procedure, as well as any required configuration on the host device. During commissioning, verify link status using the host equipment’s documented indicators and diagnostics, without assuming thresholds or behaviors that are not specified on this page.
