Description
Product Overview
SFP-10G31-LR is a 10GBASE-LR SFP+ optical transceiver for 10 Gigabit Ethernet links at a 10.3125Gbps line rate over single-mode fiber, up to 10km. It uses a 1310nm DFB laser transmitter, PIN photodiode receiver and duplex LC interface.
The module is hot-pluggable and supports digital diagnostic monitoring (DDM).
Operating Modes & Applications
This illustration shows typical optical networking applications. Network speed, fiber cabling, module pairing and host compatibility must be verified for the specific transceiver.
Connection & Selection Guide
Typical link: Compatible 10G SFP+ optical port → SFP-10G31-LR → duplex LC single-mode fiber → matching 1310nm 10GBASE-LR optical transceiver (up to 10km).
Before ordering: Verify the host supports 10GBASE-LR modules, the opposite transceiver and fiber type are compatible, and the link optical budget is suitable. A compatible SFP+ port and any vendor coding requirements must be confirmed.

Frequently Asked Questions
What is the maximum supported distance?
Up to 10km on suitable single-mode fiber, subject to the link budget and connector loss.
Which optical wavelength and connector does it use?
A nominal 1310nm optical wavelength and duplex LC interface.
Is the module compatible with multimode fiber?
This model is specified for single-mode fiber. Select an appropriate multimode transceiver if your installation uses MMF.
What speed does it support?
It is designed for 10GBASE-LR applications at a 10.3125Gbps line rate, not for 1G SFP operation.
Does it support DDM / DOM?
Yes. Digital diagnostic monitoring is supported when the host equipment exposes these readings.
Can I insert it while equipment is powered on?
Yes, in a compatible hot-pluggable SFP+ host. Follow your device manufacturer's procedures.
Will it work with any brand of switch?
Not automatically. Check the host brand, model, firmware and vendor coding requirements before ordering.
