This Calix® 100-02581 compatible SFP transceiver provides 1000Base-BX 2-Channel throughput up to 20km 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 can operate at temperatures between 0 and 70C. 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. Additional product features include Digital Optical Monitoring (DOM) support which allows access to real-time operating parameters. We stand behind the quality of our products and proudly offer a limited lifetime warranty.This Calix® 100-02581 compatible SFP transceiver provides 1000Base-BX 2-Channel throughput up to 20km over single-mode fiber (SMF) using a wavelength of 1490nmTx/1310nmRx via an LC connector.
