## Overview

The QSFPTEK 10G LR SFP+ Module delivers reliable 10Gbps data rates over single-mode fiber with a 10km reach, featuring a 1310nm wavelength and LC duplex connector. Compatible with Cisco, Mikrotik, and other open switches, it supports Digital Diagnostics Monitoring for real-time status updates. Designed for easy hot-pluggable installation and built with durable metal housing, this transceiver is ideal for professionals upgrading to high-performance 10GbE networks.

## Description

Product description 10 Gigabit Ethernet Single-mode SFP+ Module Structure Housing: SFP modules are usually protected by metal casings to provide physical protection & electromagnetic shielding PCB: Use winding technology as a circuit technology. By winding small-diameter wires around the pillars of the connection points, the durability & replaceability of the circuit are improved Optical Receiver: An electro-optical conversion device commonly used in optical communication system that can convert optical signals transmitted through optical fibers into electrical signals

Review: Reliable 10GbE Copper Transceiver, Runs Warm - This SFP+ to RJ45 module worked flawlessly with my network setup, providing stable and consistent 10GbE connectivity. The build quality is solid, and installation was plug-and-play with no compatibility issues across my switch. Latency is low, and I haven't noticed any drops in throughput even during heavy file transfers. Like most copper-based SFP+ transceivers, it does run warm, but that’s expected for 10Gb over copper. Adding some airflow in the switch enclosure helps mitigate the heat buildup. If you need a cost-effective way to upgrade to 10Gb networking, this is a solid and reliable option.
Review: Recognized by Mikrotik - Works with my Mikrotik CRS309-1G-8S+in at 10G full duplex auto. So plug and play. Does get hot 63c normal operating. Stats seem accurate inside of SwitchOs and fun to have. For the price, I'm pretty happy.

## Features

- Compatible for Mikrotik, and other Open Switch. Widely used in fiber switches, routers, NIC, server or other fiber optic equipments with 10Gb SFP+ ports.
- 10GBASE-LR SFP+ Module: 10Gb/s data rate, Single-Mode, duplex LC connector, 1310nm wavelength, the transmission distance up to 10km, working temperature: 0℃ ~ 70℃, Tx Power(dBm): -6.5 ~ -0.5, Rx Sens.(dBm): ＜ -14.4.
- Support DDM: DDM (Digital Diagnostics Monitoring) allows you to monitor the critical information concerning the status of the transmitted and received signals of the transceivers in real-time to find out some potential problems.
- Easy to use: Easy installation, plug and play, Supports hot-pluggable. Rotate the ring latch down at 90 degree angle to unlock, then pulling transceiver out from switch. High-quality metal material of housing, ensuring long life of repeated repeatedly plug and durable.
