This Calix® 100-01671 compatible SFP transceiver provides 1000Base-BX throughput up to 40km over single-mode fiber (SMF) using a wavelength of 1490nmTx/1310nmRx via an LC connector. This bidirectional unit must be used with another transceiver or network appliance of complementing wavelengths. It is capable of withstanding rugged environments and can operate at temperatures between -40 and 85C. Our transceiver is built to meet or exceed OEM specifications and is guaranteed to be 100% compatible with Calix®. It has been programmed, uniquely serialized, and tested for data-traffic and application to ensure that it will initialize and perform identically. All of our transceivers comply with Multi-Source Agreement (MSA) standards to provide seamless network integration. This transceiver is Trade Agreements Act (TAA) compliant. We stand behind the quality of our products and proudly offer a limited lifetime warranty.This Calix® 100-01671 compatible SFP transceiver provides 1000Base-BX throughput up to 40km over single-mode fiber (SMF) using a wavelength of 1490nmTx/1310nmRx via an LC connector.
