This Ciena XCVR-A40U31 compatible SFP transceiver provides 100Base-BX throughput up to 40km over single-mode fiber (SMF) at a bidirectional wavelength of 1310nmTx and 1490nmRx using a LC connector. This bidirectional unit must be used with another transceiver or network appliance of complimenting wavelengths. It is guaranteed to be 100% compatible with the equivalent Ciena transceiver. This easy to install, hot swappable transceiver has been programmed, uniquely serialized and data-traffic and application tested to ensure that it will initialize and perform identically. Digital optical monitoring (DOM) support is also present to allow access to real-time operating parameters. This transceiver is Trade Agreements Act (TAA) compliant.
