Description
Product Overview
SFP-GE31-LX is a 1.25Gbps SFP optical transceiver for Gigabit Ethernet links over single-mode fiber up to 10km. It combines a 1310nm FP laser transmitter, PIN photodiode receiver and duplex LC optical interface.
The module follows the SFP MSA and supports SFF-8472 digital diagnostics. Standard and industrial operating-temperature variants are listed in the original product information; confirm the exact part number before ordering.

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 Gigabit SFP optical host → SFP-GE31-LX → duplex LC single-mode fiber → compatible 1310nm 1G optical module (up to 10km).
Part number selection: SFP-GE31-LXC: 0°C to +70°C; SFP-GE31-LXI: -40°C to +85°C. Contact Sailtel to confirm variant pricing and availability.
Before ordering: Confirm the SFP host supports 1G optical modules, the remote transceiver and fiber are matched, and the required operating temperature and coding are supported.

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.
