This Planet® MGB-TLB40 compatible SFP transceiver provides 1000Base-BX throughput up to 40km over single-mode fiber (SMF) at a bidirectional wavelength of 1490nmTx/1310nmRx using an 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 -40C to +85C. It is guaranteed to be 100% compatible with the equivalent Planet® 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. We stand behind the quality of our products and proudly offer a limited lifetime warranty.
