This Juniper Networks® EX-SFP-1GE-LX40K-CW35U-HD1 compatible SFP transceiver provides 1000Base-CWDM throughput up to 40km over single-mode fiber (SMF) at a bidirectional wavelength of 1350nm LTx/HRx using an LC connector. This CWDM 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 guaranteed to be 100% compatible with the equivalent Juniper Networks® 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.
