1000BASE-SX SFP Transceiver

Review: XZSNET 10GBASE-SR SFP+ Transceiver (2 Pack) Model: XZSNET 10GBASE-SR SFP+ Transceiver, 10G SFP+ to LC Multimode Fiber Module Compatibility: Compatible with Cisco SFP-10G-SR, Ubiquiti UniFi UF-MM-10G, Mikrotik S+85DLC03D, Meraki, Netgear, D-Link, and other Multi-Source Agreement (MSA) compliant equipment. The Perfect Partner for Home 10Gb Fibre Networking The search for reliable, cross-compatible, and budget friendly SFP+ transceivers for a new 10 Gigabit switch can be a minefield. Many switches, including my new goalake (or similar generic brand) unit, are notoriously selective about the optics they accept. These XZSNET 10GBASE-SR modules immediately eliminated any compatibility concerns, providing a truly plug and play experience. Performance and Reliability My core requirement was simple: a rock solid, error free 10 Gigabit connection. These transceivers delivered immediately. * Flawless Speed: The modules established a continuous, full 10 Gigabit per second link. Through extensive file transfers and network stress tests, the connection remained completely stable, achieving the theoretical maximum throughput without any packet loss or connection drops. * Exceptional Stability Under Load: To properly test the reliability of the link, I performed a substantial, sustained data transfer, pushing over 500 gigabytes of data from one computer to another, and then immediately back again. The entire process completed perfectly, without a single error, dropped connection, or speed fluctuation. This demonstrates the transceiver's ability to maintain rock solid performance under heavy, prolonged network load. * Real World Distance Test: My fibre run is 60 metres of OM3 multimode cable, which is well within the 300 metre standard for this type of transceiver. At this distance, the connection performance was exceptional. The use of the standard 850 nanometre wavelength and LC duplex connector meant installation into the fibre patch cable was instantaneous. * Zero Handshake Issues: The transceivers were instantly recognised and accepted by the switch, lighting up immediately and establishing a link with the module on the far end. For anyone worried about using third party optics with a switch that often expects expensive name brand modules, these generics function perfectly by using the required MSA coding for broad compatibility. The Technical Details and Value Proposition The "SR" in 10GBASE-SR stands for Short Reach, making this module type the ideal choice for any home or small office network running multimode fibre. * Technology: These are multimode fibre modules, specifically designed to run over OM3 or OM4 cable, offering up to 300 metres of 10 Gigabit connectivity over OM3. This combination is far more cost effective for shorter runs than single mode alternatives. * Hot Swappable: As expected with SFP+ modules, these are hot swappable, allowing you to add or remove them without having to power down your network equipment, which is a small but useful feature during setup. * Cost Effectiveness: Buying a two pack of these generics offers phenomenal value compared to the price of a single equivalent OEM module. They provide the same 10Gb per second performance and adherence to the necessary IEEE 802.3ae standard for a fraction of the cost, making 10 Gigabit networking accessible to enthusiasts. Final Verdict The XZSNET 10GBASE-SR SFP+ transceivers are an unreserved recommendation for anyone building out a 10 Gigabit home lab or network using multimode fibre. They are the perfect, non fussy solution for switches that can be sensitive to third party hardware, providing reliable, continuous, and high speed 10Gb per second connectivity out of the box. They are a genuinely rock solid product.

One of two died within a couple of weeks after delivery, the other one is working just fine. I'm giving the product 5* though as the manufacturer picked up the issue from my earlier review and promptly shipped a replacement. Well done - that's what a reliable manufacturer should do!

Has been working fine in my UDR7 for a couple of months now and achieves expected speeds - good value compared to other options.

Edit. sept 2025. The supplier saw my review and contacted me to send an immediate replacement. It arrived the same day. I’ll see how this one goes. I’ll leave the original review below but I cannot fault the customer service and give them 5 stars. ————- Original review Worked great for about 9 months, but now it needs "rebooting" every few days. I have to unplug and re-seat it. I was running a simple ping test and every 30 seconds it would drop exactly 8 packets then reconnect. I unseated it and it would work properly again for 2 or 3 days. It's under very little load (not that should matter), but it runs a back 5G router thats never used. One for the bin I'm afraid.

Using these in a GigaPlus 10 Port 2.5Gb Unmanaged PoE Switch with 8*2.5G Base-T PoE Ports + 2*SFP+ slots. They worked immediately, and very eell, but... RJ45 SFPs generally can get very hot, so wise to use in a switch with some active cooling capability, or attach some small finned copper heat sinks. Would have been 5 stars if they ran a bit cooler.

Picked this up in June for my UniFi setup and it’s been superb. Slotted straight into the SFP+ port, no messing about, and was recognised instantly. Been running 10G solid ever since without a single drop or hiccup. Doesn’t run overly hot, feels well made, and has just blended into the rack doing exactly what it should. Nice not having to think about it – it just works. For the price, it’s a cracking bit of kit and I’ll happily get more when I expand the network.

Fits my equipment with no issues, I've had no issues with heat or speed so far, would recommend. Plug and play.

These work perfectly on Ubuiquitti switches. Hopefully they last well. Good price and I will buy again.

結構高温になるので心配だが、安定して動いている

Works great on my Brocade ICX7750, yet to try on the 7250. Even negotiates down to 1Gb which is awesome in the event that I need a gigabit connection. Temps seemed stable at 1Gb, 5 Gb and 10Gb but my switch has loads of airflow over the SFP cages so your milage may vary.

Runs very hot at 5gbit but works well.

Works as expected and perfectly. Inexpensive module works with EdiMax Pro, Mokerlink and TRENDnet switches for certain.

Fonctionne parfaitement pour mon Cisco Catalyst 3560, ils sont bien compatibles, je recommande
