FAQ
What Cisco switches are these SFP modules compatible with?
These modules are 100% compatible with Cisco switches including Firepower series, ASR920, IE2000, IE4000, and ASR1000 models. They are tested to work seamlessly in Cisco environments without voiding OEM support, and also function with other MSA-compliant switches from brands like Ubiquiti, D-Link, Netgear, Supermicro, and TP-Link that accept uncoded modules.
What is the maximum transmission distance for these SFP modules?
These 1000BASE-LX/LH SFP modules support transmission distances up to 40 kilometers (approximately 24.8 miles) when used with single-mode fiber. The actual achievable distance may vary based on fiber quality, connectors, and network conditions, but the modules are designed for long-haul optical connections in enterprise and data center deployments.
Do these modules support Digital Diagnostic Monitoring (DDM)?
Yes, these SFP modules include Digital Diagnostic Monitoring (DDM) support, which provides real-time monitoring of key parameters such as temperature, voltage, bias current, and optical power levels. This data is accessible through SNMP network management tools, enabling proactive maintenance, troubleshooting, and performance optimization in network environments.
Can I hot-swap these SFP modules while the switch is powered on?
Yes, these modules feature a hot-pluggable form factor that allows installation or removal while the networking equipment is powered on and operational.
