Frequently Asked Questions
What is 25GBASE-BX40-D and how does it differ from other SFP+ standards?
25GBASE-BX40-D is an IEEE standard for 25 Gbps bidirectional transmission over single-mode fiber with a 40 km reach. Unlike point-to-point standards, the BX40-D uses wavelength division multiplexing (WDM) to send and receive data simultaneously over a single fiber strand, reducing cabling costs while maintaining high performance for long-distance connections.
Is this Axiom SFP+ module compatible with my Cisco equipment?
Yes, the Axiom 25GBASE-BX40-D SFP+ is designed for Cisco compatibility and works with standard SFP+ ports on Cisco switches, routers, and network interface cards. Verify your specific Cisco model supports 25GBASE-BX40-D before deployment to ensure optimal performance.
How far can this 25 Gbps SFP+ module transmit data?
The Axiom 25GBASE-BX40-D supports transmission distances up to 40 km over single-mode fiber, making it suitable for metropolitan area networks, campus interconnects, and inter-building links without requiring signal regeneration or additional equipment.
Can I use this module for short-distance connections?
Yes, while rated for 40 km reach, the 25GBASE-BX40-D SFP+ module operates reliably at shorter distances. It's ideal for both long-haul and medium-range deployments, providing flexibility for various network topologies and future expansion.
