Product Specifications

Long-Distance 1 Gigabit Connectivity

This SFP module supports a maximum transfer distance of 10 km over single-mode fibre. This is ideal for connecting buildings or campus sites without signal loss. Because it uses a 1310 nm wavelength, it maintains integrity over long runs. So, you can extend your network backbone reliably.

Hot-Swap Capability for Minimal Downtime

The module is hot-swappable, meaning you can install or replace it without powering down your switch. This feature reduces network disruption during maintenance or upgrades. In practice, this saves time for your IT team. It also simplifies inventory management for spares.

Dual-Mode Fibre Support

It supports both single-mode and multi-mode fibre, giving you deployment flexibility. You can use it for short intra-building links or long-distance runs. This versatility is useful for mixed infrastructure environments. Always verify your fibre type matches the module’s LC connector and 1310 nm wavelength.

Digital Diagnostics Monitoring (DDM)

This module includes DDM, which provides real-time transceiver diagnostics. You can monitor parameters like optical power and temperature. This helps with proactive network maintenance and troubleshooting. It is a key feature for ensuring long-term link stability.

Wide Compatibility and Standards Compliance

It follows IEEE 802.3z standards and is compatible with Cisco GLC-LH-SMD. The module also supports Auto MDI/MDI-X for simplified cabling. It is CE and RoHS compliant for UK and EU markets. However, always confirm specific switch model compatibility before purchase.
