This 2-pack of Ubiquiti UF-MM-1G compatible SFP transceivers provides 1000Base-SX throughput up to 550m over multi-mode fiber (MMF) using a wavelength of 850nm via an LC connector. Each is guaranteed to be 100% compatible with the equivalent Ubiquiti transceiver. This easy to install, hot swappable transceiver has been programmed, uniquely serialized 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.
