SFP-10G-LRM

Cisco SFP-10G-LRM module

The Cisco 10GBASE-LRM Module supports link lengths of 220m on standard Fiber Distributed Data Interface (FDDI) grade Multimode Fiber (MMF). To make sure that specifications are met over FDDI-grade, OM1 and OM2 fibers, the transmitter should be coupled through a mode conditioning patch cord. No mode conditioning patch cord is required for applications over OM3 or OM4.

The Cisco SFP-10G-LRM module is a small form-factor pluggable (SFP+) optical module for 10G Ethernet, mainly used in multimode fiber networks. The following is a detailed introduction to its parameter information:

Basic specifications

Standard compliance: Complies with the IEEE 802.3ae 10GBASE - LRM Ethernet standard and SFP+ MSA (Multi-Source Agreement), ensuring interoperability with other compatible devices.

Transmission rate: Supports data transmission rates up to 10.3125Gbps, enabling high-speed and stable network communication.

Optical characteristics

Wavelength: Uses a 1310nm distributed feedback (DFB) laser as the light source.

Transmission distance: On OM1 or OM2 multimode fiber, the maximum transmission distance can reach 220 meters.

Transmitted optical power: The typical transmitted optical power ranges from -8.2dBm to -2.3dBm.

Receiving sensitivity: The minimum receiving sensitivity is about -14.4dBm, which can reliably detect weak optical signals.

Extinction ratio: Generally greater than 3.5dB.
