Frequently Asked Questions
What is a QSFP28 100G-CWDM4 transceiver used for?
The QSFP28 100G-CWDM4 transceiver is used to establish high-speed 100 Gbps optical connections in data center networks, campus area networks, and enterprise infrastructure. CWDM4 technology allows multiple wavelengths to travel over a single fiber strand, maximizing bandwidth efficiency while reducing cabling costs. This makes it essential for organizations upgrading to 100G connectivity without replacing existing fiber infrastructure.
Is this QSFP28 transceiver compatible with Cisco equipment?
Yes, this ADD-ON QSFP28 LC 100G-CWDM4 module is specifically designed for Cisco compatibility. It works seamlessly with Cisco Nexus switches, UCS systems, and other Cisco platforms supporting QSFP28 ports. Always verify your specific switch model supports QSFP28 form factor and 100G speeds before deployment.
What distance does the 2km CWDM4 transceiver support?
This 100G-CWDM4 2km transceiver supports optical transmission distances up to 2 kilometers over standard single-mode fiber (SMF). This distance is ideal for intra-data center connections, building-to-building campus links, and metropolitan area network (MAN) deployments. For longer distances, consider 10km or 40km CWDM4 variants.
What monitoring capabilities does this optical module provide?
The ADD-ON QSFP28 transceiver includes Digital Diagnostic Monitoring (DDM) functionality, enabling real-time monitoring of optical power levels, temperature, and module health. This allows network administrators to proactively identify performance issues, optimize signal quality, and plan maintenance before failures occur.
