1000BASE-BX40-D and 1000BASE-BX40-U for Single-Fiber Bidirectional Applications

The Cisco GLC-BX40-D-I, GLC-BX40-DA-I and GLC-BX40-U-I SFPs operate on a single strand of

standard SMF.


A GLC-BX40-D-I or GLC-BX40-DA-I device connects to a GLC-BX40-U-I device with a single strand

of standard SMF with an operating transmission range up to 40 km. The communication over a single

strand of fiber is achieved by separating the transmission wavelength of the two devices.


The GLC-BX40-D-I, GLC-BX40-DA-I, and GLC-BX40-U-I SFPs also support digital optical monitoring

(DOM) functions according to the industry-standard SFF-8472 multisource agreement (MSA). 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.
