Overview
The SFP-10G-LRM Cisco compatible SFP+ transceiver module is a high-performance 10G optical networking solution designed for reliable and stable Ethernet transmission over multimode fiber (MMF) and legacy fiber infrastructure. Operating at a 1310nm wavelength with LC duplex interface, it supports distances of up to 220 meters, making it ideal for enterprise networks, data centers, and switch-to-switch connectivity.
Fully compliant with IEEE 10GBASE-LRM standards, this module ensures seamless interoperability with Cisco switches, routers, and other SFP+ compatible networking devices. It offers low power consumption, hot-pluggable functionality, and built-in Digital Optical Monitoring (DOM) for real-time diagnostics, helping network administrators maintain high performance and reduce downtime.

FAQ
What is SFP-10G-LRM used for?
It is used for 10G Ethernet connections over multimode fiber, especially in environments where existing fiber infrastructure is reused.
Is this module compatible with Cisco devices?
Yes. It is fully compatible with Cisco switches, routers, and other devices that support SFP+ 10G interfaces.
Do I need a mode conditioning patch cord?
- Required for OM1/OM2 fiber
- Optional for OM3/OM4 fiber
What is the maximum distance supported?
The module supports up to 220 meters over multimode fiber, depending on fiber quality and network conditions.
Does it support DOM monitoring?
Yes. It supports Digital Optical Monitoring, including:
- Optical power levels (TX/RX)
