Frequently Asked Questions
What is a 40GBASE-DWDM QSFP+ transceiver used for?
A 40GBASE-DWDM QSFP+ transceiver is used for long-distance, high-speed optical communication in data centers, metropolitan area networks (MANs), and wide area networks (WANs). It enables 40 Gigabit Ethernet transmission over single-mode fiber up to 80 km, making it ideal for connecting remote facilities or scaling network capacity without upgrading backbone infrastructure.
Is the Axiom QSFP+ 80km transceiver compatible with my existing equipment?
Yes. The Axiom 40GBASE-DWDM QSFP+ module is 100% MSA-compliant and designed for OEM compatibility. It works with standard QSFP+ ports on switches, routers, and network interface cards from major vendors. Always verify your equipment supports DWDM wavelengths at 1539.77nm before deployment.
What are the advantages of DWDM over standard 40GBASE-LR4?
DWDM technology allows multiple wavelengths to travel simultaneously on a single fiber, dramatically increasing bandwidth capacity without laying new cable. The Axiom 40GBASE-DWDM QSFP+ achieves 80 km reach with superior spectral efficiency compared to standard 40GBASE-LR4, making it cost-effective for high-density, long-haul deployments.
What fiber type does this 80km transceiver require?
This module requires single-mode fiber (SMF) with LC connectors. SMF is essential for long-distance transmission at 80 km; multimode fiber would result in signal degradation and link failure. Ensure your fiber infrastructure meets ITU-T G.652 or equivalent standards for optimal performance.
