## Overview

The 10Gtek SFP-10G-SR is a high-performance 10Gbps SFP+ transceiver module designed for multimode fiber (OM3/OM4) with an 850nm wavelength, supporting link distances up to 300 meters. Compatible with a wide range of major brands including Cisco, Meraki, and Ubiquiti, it offers plug-and-play ease, robust metal housing, and reliable long-term operation—ideal for professional-grade networking in enterprise, SMB, and home lab environments.

## Description

For Cisco SFP-10G-SR, 10GBASE-SR Module supports a link length of 26m on standard Fiber Distributed Data Interface (FDDI)-grade multimode fiber (MMF). Using 2000MHz*km MMF (OM3), up to 300m link lengths are possible. Using 4700MHz*km MMF (OM4), up to 400m link lengths are possible.Specifications:Compatible Cisco P/N: SFP-10G-SR 10GBASE-SR SFP+ transceiver module for MMF, 850-nm wavelength, LC duplex connector.

Review: Good value for money: Many users report that these modules work as expected for 10 Gbps fiber links and deliver full 10 G speeds with proper multimode fiber (OM3/OM4, LC) up to ≈300 m. They’re often praised for being plug-and-play and compatible with a broad range of switches and NICs (Cisco, Dell, Aruba, Ubiquiti, Mikrotik, etc.), though results can vary by brand and firmware. Especially for home labs, small business networks, and DIY deployments, they’re seen as a cost-effective alternative to OEM modules. Decent reliability: Some users who have used them for a year+ have reported no failures or speed issues. Physical build quality (metal housing, low power draw) is generally considered fine for frequent use.
Review: Well packaged in metal tins. Works with qnap QSW-2104-2S switch and Intel pcie 520 chipset running on freebsd. Very happy. :-).
