Refurb/SFP+Bidirectional 10km Upstream

The Cisco SFP-10G-BXU-I-RF SFPs operate on a single strand of standard SMF. The communication over a single strand of fiber is achieved by separating the transmission wavelength of the devices. The SFP-10G-BXU-I-RF transmits at a 1270-nm wavelength and receives a 1330-nm signal. The SFP-10G-BXU-I-RF SFPs also support Digital Optical Monitoring (DOM) functions. This feature gives the end user the ability to monitor real-time parameters of the SFP, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.
