This Calix 100-01510-BXU-40 compatible SFP+ transceiver provides 10GBase-BX throughput up to 40km over FALSE at a bidirectional wavelength of 1270nmTx and 1330nmRx using a LC connector. This bidirectional unit must be used with another transceiver or network appliance of complimenting wavelengths. It is also capable of withstanding rugged environments and can operate at temperatures between -40°C to +85°C. It is guaranteed to be 100% compatible with the equivalent Calix 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. It is built to meet or exceed the specifications of Calix, as well as to comply with MSA (Multi-Source Agreement) standards to ensure seamless network integration. All of our transceivers are Trade Agreements Act (TAA) compliant.
