SFP-module Cisco SFP-10G-LRM= 10GBASE-LRM

The Cisco SFP-10G-LRM= is a 10GBASE-LRM SFP transceiver module that provides 10-Gigabit Ethernet connectivity for multimode fibre infrastructures. It is intended for installations using older multimode fibre types such as FDDI, OM1 and OM2 and supports optical interoperability with 10GBASE XENPAK, X2 and XFP interfaces on the same link.

Advantages

The module supports link lengths on FDDI, OM1 and OM2 multimode fibre up to the specified range and fits into standard SFP+ Ethernet ports for straightforward installation. It is hot-swappable to allow replacement or upgrade without powering down the switch. Compact dimensions and low typical power consumption make it suitable for dense switch environments where space and power efficiency matter.

Suitable for

• Connecting 10-Gigabit Ethernet on legacy multimode fibre (FDDI, OM1, OM2)
• Upgrading multimode links while maintaining interoperability with XENPAK/X2/XFP equipment
• Hot-swap installations and modular switch deployments

How to use

Insert the Cisco SFP-10G-LRM= transceiver into an SFP+ port on a compatible Cisco switch or other networking device while the module and port are properly aligned. The module is hot-swappable, so it can be inserted or removed without powering down the device. Terminate and connect the multimode fibre (FDDI, OM1 or OM2) using appropriate connectors and observe correct fibre handling and safety procedures. Configure the switch port according to your network requirements to enable 10-Gigabit operation.

Recommendations

Use this module on multimode fibre installations where the cable type and link length meet the 10GBASE-LRM specifications; verify compatibility with existing optics (XENPAK, X2, XFP) on the same link and follow manufacturer guidelines for fibre connector types and cleaning.
