Cisco SFP-10G-BXU-I= network transceiver module Fiber optic 10000 Mbit/s SFP+ 1270 nm

The Cisco SFP-10G-BXD-I and SFP-10G-BXU-I SFPs operate on a single strand of standard SMF.

A SFP-10G-BXD-I device is always connected to a SFP-10G-BXU-I device with a single strand of standard SMF with an operating transmission range up to 10 km.

The communication over a single strand of fiber is achieved by separating the transmission wavelength of the two devices. SFP-10G-BXD-I transmits a 1330-nm channel and receives a 1270-nm signal, whereas SFP-10G-BXU-I transmits at a 1270-nm wavelength and receives a 1330-nm signal. The presence of a wavelength-division multiplexing (WDM) splitter integrated into the SFP to split the 1270-nm and 1330-nm light paths.
