1000BASE-BX Bidirectional 10 km SFP Modules

Part numbers: 10056H, 10057H, MGBIC-BX10-D, MGBIC-BX10-U

The 1000BASE-BX SFP modules include the 1000BASE-BX-U SFP module and the 1000BASE-BX-D SFP module. These two SFP modules are used together to permit a bidirectional GE (Gigabit Ethernet) connection using a single strand of SMF cable and LC connectors.

The 1000BASE-BX-D SFP module operates at wavelengths of 1490 nm TX/1310 nm RX, and the 1000BASE-BX-U SFP module operates at wavelengths of 1310 nm TX/1490 nm RX. The 1000BASE-BX-U SFP module is always connected to the 1000BASE-BX-D SFP module. The maximum transmission distance for this connection is 10 km. The 1000BASE-BX SFP modules conform to the IEEE 802.3ah 1000BASE-BX10 standard.

For a complete listing of hardware compatible with these modules, see the Extreme Optics Compatibility website.

Transmission distances are provided as a nominal guide only. To determine achievable distances, refer to the device's optical specifications and to the specific characteristics of your fiber installation.

1000BASE-BX Bidirectional SFP Specifications

The MGBIC-BX10-D/-U SFP modules operate at a commercial temperature range (0°C to 70°C). The 10056H/10057H Industrial Grade SX SFP modules operate at a wide temperature range (-40°C to 85°C)

Note

The 1000BX bidirectional SFPs include two SFP optical devices, the 1000BASE-BX-U SFP and the 1000BASE-BX-D SFP, which must be used as a pair to create a single fiber bidirectional connection.
