SFP-10G-LRM-BCC | Cisco Compatible 10GB Multi-Mode LRM - 220m (10GBASE-LRM)

Q: Will this work in place of the Cisco SFP-10G-LRM?
A: Yes. The SFP-10G-LRM-BCC conforms to the IEEE 802.3aq 10GBASE-LRM standard and the SFP+ MSA, delivering the same 10.3125 Gbps data rate, 1310nm wavelength, and reach profile as the Cisco original. It is plug-and-play compatible with any Cisco platform that supports the SFP-10G-LRM.

Q: Which Cisco platforms support this module?
A: This module is compatible with Cisco switches and routers that have SFP+ ports supporting 10GBASE-LRM optics. Refer to the Cisco 10 Gigabit Ethernet Transceiver Modules Compatibility Matrix for platform-specific qualification, as supported models span Catalyst, Nexus, ASR, and other product families.

Q: When is a mode conditioning patch cord required?
A: Mode conditioning patch cords are required when deploying this module over FDDI-grade, OM1, or OM2 multimode fibre to meet full IEEE 802.3aq distance specifications and prevent differential mode delay. They are not required for OM3, OM4, or single-mode fibre. The patch cord must be installed at the transmitter end of each fibre pair.

Q: Can this module operate on single-mode fibre, and what is the maximum reach?
A: Yes. The SFP-10G-LRM-BCC supports up to 300m on standard G.652 single-mode fibre without requiring mode conditioning. This makes it suitable for short single-mode links or mixed deployments where both multimode and single-mode segments exist. Standard LC/PC patch cords are used for single-mode connections.

Q: What is the minimum link distance, and why does it matter?
A: The minimum link distance is 2 metres per IEEE 802.3ae. Unlike some 10G optics that require attenuation at very short distances, 10GBASE-LRM modules have no minimum attenuation requirement, allowing direct rack-to-rack or intra-rack connections without additional optical components.
