Planet MTB-LR SFP+ Port 10GBASE-LR Mini-GBIC Module (Single mode / 310 nm / max. 10 km)

The PLANET MTB-LR is a 10 Gbps SFP+ 10GBASE-LR fiber transceiver with an LC connector for single-mode fiber links up to 10 km, suited to network administrators connecting compatible switches, routers, or network cards over longer distances.

Recommended For

• Network administrators linking switches or routers across buildings over installed single-mode fiber who need a 10GbE link up to 10 km and compatible SFP+ ports at both ends.
• IT teams extending a campus, office, or enterprise network where a 10GbE fiber uplink is needed beyond typical short in-rack connections, and the existing fiber is single-mode with LC connectors.
• Network technicians troubleshooting or monitoring a supported optical link who want digital diagnostic monitoring (DDM) from the transceiver.
• Operators of PLANET networking equipment with an SFP+ interface who need a PLANET-listed 10GBASE-LR module for a single-mode fiber connection.

Real-World Use Scenarios

• To link switches in separate network rooms or buildings over installed single-mode fiber, use a compatible 10G SFP+ port at each end; the link can carry network traffic at 10Gbps over distances up to 10km when the fiber path and equipment are suitable.
• To connect a server or workstation with an SFP+ NIC to a switch over a fiber run, use matching LR optics at both ends; this provides a 10Gbps network link for large transfers or storage traffic, subject to the speed of the endpoints and storage.
• To connect a NAS or storage server to a network switch over single-mode fiber, use the module where both devices support compatible 10G SFP+ links; it can provide more headroom for large file transfers and shared-storage traffic than a slower network link.
• To join a distribution switch to a core or aggregation switch across an existing single-mode fiber route, install compatible LR modules at both ends; this creates a 10Gbps backbone link without needing to run copper Ethernet between the locations.
• When diagnosing a fiber link, use the transceiver’s digital diagnostic monitoring through compatible network equipment to check optical and module readings; this can help narrow down link issues, but it does not replace checking fiber connections and device compatibility.
