1000BASE-BX10-D and 1000BASE-BX10-U SFP for Single-Fiber Bidirectional Applications
The 1000BASE-BX-D and 1000BASE-BX-U SFPs, compatible with the IEEE 802.3ah 1000BASE-
BX10-D and 1000BASE-BX10-U standards, operate on a single strand of standard SMF.
A 1000BASE-BX10-D device is always connected to a 1000BASE-BX10-U 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 as depicted in Figure 2: 1000BASE-BX10-D transmits a 1490-nm
channel and receives a 1310-nm signal, whereas 1000BASE-BX10-U transmits at a 1310-nm
wavelength and receives a 1490-nm signal. Note in Figure 2 the presence of a wavelength-division
multiplexing (WDM) splitter integrated into the SFP to split the 1310-nm and 1490-nm light paths.

The GLC-BX-D and GLC-BX-U SFPs also support digital optical monitoring (DOM) functions
according to the industry-standard SFF-8724 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.
Technical Specifications
Platform Support
The Cisco SFPs are supported across a variety of Cisco switches, routers, and optical transport
devices. For more details, refer to the document SFP Compatibility Matrix.
Connectors and Cabling
Connectors include the following:
●
Dual LC/PC connector (1000BASE-SX, 1000BASE-LX/LH, and 1000BASE-ZX)
●
Single LC/PC connector (1000BASE-BX-D and 1000BASE-BX-U)
Note:
Only connections with patch cords with PC or UPC connectors are supported. Patch
cords with APC connectors are not supported. All cables and cable assemblies used must be
compliant with the standards specified in the standards section.
Table 1 provides cabling specifications for the SFPs that you install in the Gigabit Ethernet port.
Note that all SFP ports have LC-type connectors, and the minimum cable distance for all SFPs
listed (multimode and single-mode fiber) is 6.5 feet (2 m).
