Frequently Asked Questions
What is the maximum transmission distance supported by the Cisco GLC-BX40-DA-I? +
The GLC-BX40-DA-I is designed for long-reach Gigabit Ethernet applications, supporting data transmission over single-mode fiber optic cables at distances of up to 40 kilometers. This makes it an ideal choice for connecting campus buildings or remote enterprise branch offices while maintaining high signal integrity across extended metropolitan fiber runs.
Does the GLC-BX40-DA-I require a specific fiber pairing for bidirectional communication? +
Yes, as a BiDi (Bidirectional) SFP module, this unit uses a single strand of fiber to transmit and receive data by using different wavelengths for each direction. It must be paired with a compatible downstream module, typically the GLC-BX40-U-I, which uses the inverse wavelength pair to ensure seamless communication on your network link.
What does the 'I' suffix in the GLC-BX40-DA-I model name signify? +
The 'I' in this SKU stands for Industrial temperature rating. This indicates that the transceiver is ruggedized to operate reliably in harsh environments where temperatures fluctuate significantly beyond standard commercial ranges. This makes it suitable for deployments in outdoor cabinets, industrial manufacturing floors, or locations without climate-controlled infrastructure.
Is the GLC-BX40-DA-I compatible with standard Cisco SFP ports? +
This module adheres to the industry-standard Small Form-Factor Pluggable (SFP) footprint, allowing it to be hot-swapped into any Cisco switch or router port that supports the 1000BASE-BX10-D/U standard. Ensure your hardware platform supports the specific BiDi wavelength requirements to avoid link synchronization issues during deployment.
How do I manage or configure the GLC-BX40-DA-I module on a Cisco switch? +
Configuration for this transceiver is handled automatically by the Cisco IOS software once inserted into a supported port. You can monitor the module's performance, optical power levels, and status through standard CLI commands such as 'show interfaces transceiver'. No manual software installation or driver configuration is required for basic plug-and-play functionality.
What is the primary benefit of using BiDi technology like the GLC-BX40-DA-I? +
The main advantage is infrastructure efficiency. By utilizing a single strand of single-mode fiber for both directions of traffic, you effectively double the capacity of your existing fiber plant. This eliminates the need for expensive trenching or pulling new cable when upgrading network links, significantly reducing overall project costs.
Does the GLC-BX40-DA-I support Digital Optical Monitoring (DOM)? +
Yes, this module supports Digital Optical Monitoring, which provides real-time access to critical operating parameters. Network administrators can remotely monitor temperature, transmit/receive optical power, and supply voltage. These diagnostic capabilities are essential for proactive troubleshooting, allowing you to identify potential degradation in fiber links before a complete service outage occurs.
Can the GLC-BX40-DA-I operate in a standard 1000BASE-T RJ45 port? +
No, the GLC-BX40-DA-I is an optical transceiver specifically designed for fiber optic cabling. It cannot be used in a copper RJ45 port. You must ensure your networking equipment includes SFP-capable fiber slots. Attempting to use this module with an incompatible copper port will not result in a link, as the physical medium interfaces are entirely different.
How can I obtain a bulk quote for multiple Cisco GLC-BX40-DA-I modules? +
