Frequently Asked Questions
What is the primary function of the Cisco GLC-BX40-DA-I BiDi SFP module? +
The GLC-BX40-DA-I is a bidirectional transceiver designed for single-strand fiber deployments. By using different wavelengths for transmit and receive signals on the same fiber strand, it effectively doubles the utility of your existing fiber infrastructure, making it an ideal solution for increasing bandwidth capacity in space-constrained or fiber-limited enterprise environments.
What is the maximum reach of the GLC-BX40-DA-I transceiver? +
This transceiver is specifically engineered for long-reach applications, supporting a transmission distance of up to 40 kilometers over single-mode fiber (SMF). This makes it a reliable choice for connecting campus buildings or remote branch offices that require high-speed connectivity across significant geographic spans while maintaining signal integrity.
Are there specific fiber type requirements for the GLC-BX40-DA-I? +
Yes, this module is optimized for use with single-mode fiber optic cabling. To ensure optimal performance and reach the specified 40-kilometer distance, users should ensure the fiber plant is properly terminated and cleaned to minimize optical loss, which is critical when deploying BiDi modules that rely on precise wavelength multiplexing.
How does the 'I' suffix in GLC-BX40-DA-I affect its operational environment? +
The 'I' designation denotes that this module belongs to Cisco’s Industrial temperature range series. It is built to withstand more extreme environmental conditions than standard commercial-grade optics, providing stable performance in settings where temperature fluctuations are common, such as non-climate-controlled wiring closets or industrial networking environments.
Does the GLC-BX40-DA-I require a matching pair to function? +
BiDi modules operate in pairs, and the GLC-BX40-DA-I is designed to work in conjunction with its counterpart. You must ensure that the transceiver at the opposite end of the fiber link uses the complementary wavelength to correctly transmit and receive data over the single fiber strand.
Is the GLC-BX40-DA-I compatible with standard Cisco SFP slots? +
This module features a standard SFP (Small Form-factor Pluggable) form factor, ensuring it is compatible with a wide array of Cisco switches, routers, and interface cards equipped with SFP ports. Always verify the specific hardware support list for your switch to ensure the software version supports this specific optic type.
How should I monitor the performance of the GLC-BX40-DA-I? +
The module supports Digital Optical Monitoring (DOM) features, which allow network administrators to monitor real-time parameters such as optical output power, input power, temperature, and transceiver supply voltage. Utilizing these diagnostics through the Cisco CLI or management software helps proactively identify potential link degradation before it results in connectivity issues.
What is the typical data rate supported by this SFP module? +
The GLC-BX40-DA-I is designed for 1 Gigabit Ethernet applications. It provides a reliable and consistent 1Gbps data throughput, making it a standard choice for enterprise backhaul links or uplink connections where high-speed, long-distance connectivity is required between network nodes using single-mode fiber.
How can I obtain a bulk quote for the GLC-BX40-DA-I from BuyRouterSwitch.com? +
