This MSA compliant SFP transceiver provides 1000Base-CWDM HD1 throughput up to 40km over single-mode fiber (SMF) at a bidirectional wavelength of 1430nm LTx/HRx using an LC connector. This CWDM HD transceiver allows for high-density transmission of data by utilizing common CWDM wavelengths as center wavelengths for bidirectional data transmission, doubling the data channels. It is built to MSA standards and is uniquely serialized and data-traffic and application tested to ensure that they will integrate into your network seamlessly. 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.
