Product Details
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.

Frequently Asked Questions
What is the primary function of the Cisco GLC-BX40-DI SFP module? +
The Cisco GLC-BX40-DI is a 1000BASE-BX40-D BiDi SFP transceiver designed to facilitate Gigabit Ethernet connectivity over a single strand of single-mode fiber. By utilizing WDM technology, it transmits data at 1550 nm and receives at 1310 nm, effectively doubling the capacity of existing fiber infrastructure without requiring additional cable pulls.
What kind of cabling infrastructure does the GLC-BX40-DI require? +
This transceiver is engineered for single-mode fiber (SMF) applications. It features a single LC/PC connector, which is essential for bidirectional transmission over one strand. Ensure your fiber plant is properly terminated with LC connectors and that the fiber type matches the single-mode requirements for the 40km reach specified by this module.
What is the maximum reach for the GLC-BX40-DI module? +
The GLC-BX40-DI is rated for a maximum transmission distance of up to 40 kilometers over single-mode fiber. This makes it an ideal solution for long-range enterprise campus connectivity or regional service provider extensions where fiber count is limited and efficiency is a priority.
Does the GLC-BX40-DI support Digital Optical Monitoring (DOM)? +
Yes, the 'I' in the GLC-BX40-DI part number signifies that this module supports Cisco’s Digital Optical Monitoring (DOM) features. This allows network administrators to monitor real-time parameters such as optical output power, input power, temperature, and transceiver supply voltage, providing critical visibility for proactive troubleshooting and link health maintenance.
Which partner module is required to pair with the GLC-BX40-DI? +
For bidirectional links to function correctly, you must pair the GLC-BX40-DI (which transmits at 1550 nm) with its complementary counterpart, the GLC-BX40-U-I (which transmits at 1310 nm and receives at 1550 nm). Always ensure you have a matched 'Upstream' and 'Downstream' pair to ensure stable link establishment.
Can I use the GLC-BX40-DI in a standard 1G SFP port? +
This module is designed to fit into standard 1G SFP slots found on Cisco switches and routers. Before deployment, confirm that the specific hardware platform supports the 1000BASE-BX standard and that the switch software version is compatible with this transceiver type to ensure the port initializes correctly.
Is the GLC-BX40-DI suitable for industrial environments? +
The GLC-BX40-DI is part of Cisco’s industrial-grade transceiver series. It is built to withstand a wider range of operating temperatures compared to standard commercial modules. This robust design makes it a reliable choice for deployment in environments where temperature fluctuations are common, such as outdoor enclosures or manufacturing facilities.
How does the BiDi capability of this module improve network efficiency? +
BiDi or 'Bidirectional' technology utilizes Wavelength Division Multiplexing to transmit and receive on a single strand of glass. By effectively halving the fiber requirement, you significantly reduce the complexity of patch panels and cable management, while simultaneously lowering operational costs associated with leasing or installing additional dark fiber strands.
How can I obtain a bulk quote for multiple GLC-BX40-DI units? +
