10GBASE-T SFP+ 80m Module Transceiver Copper RJ-45 Cat6a/7 Mini-GBIC for Ubiquiti Unifi Ufiber UF-RJ45-10G-80, Netgear AXM76510G, 10Gigabit Ethernet, White, ON-OFF-ON Switch

I have previously purchased and used 10GBase-T SFP+ 30m (Marvell 88X3310) modules from two other vendors (Wiitek & MikroTik), as well as a 10GBase-T SFP+ 80m (Broadcom BCM84891) module from one other vendor (10Gtek). These modules have been used in MikroTik hardware; specifically the MikroTik CCR2004-1G-12S+2XS ("CCR2004") and the MikroTik CRS317-1G-16S+RM ("CRS317").I purchased two of these Fiber Mall 10GBase-T SFP+ 80m (Broadcom BCM84891) modules in the hopes of getting a Broadcom BCM84891-based module with working temperature/voltage reporting, as that is something that is missing from both the Wiitek Marvell 88X3310-based and 10GTek Broadcom BCM84891-based modules.While the MikroTik Marvell 88X3310-based modules do have working temperature/voltage reporting, they are unfortunately extremely hot and power hungry (far more so than every other Marvell 88X3310-based module out there — which is particularly annoying given that the MikroTik Marvell 88X3310-based module is the only SFP+ 10GBase-T module with fully working NBASE-T support!).Anyways, among all of these modules, these Fiber Mall Broadcom BCM84891-based modules are easily & by far my favorites so far! Why?#1: They have working temperature/voltage reporting! This is a rarity on Marvell 88X3310-based modules, and the only other Broadcom BCM84891-based module I have been able to test so far also lacked working temperature/voltage reporting, so this is a very big advantage!#2: They have had no trouble whatsoever with reliably achieving a 10GBase-T link on my longest run of cat5e (which cannot be said of any of the Marvell 88X3310-based modules, which struggle to manage a 5GBase-T link at the absolute most, and will typically settle at only 1000Base-T on that run).(Please note that I have been able to successfully push 10 Gbps over a cat5e run approximately ~3x this distance by going from my port 1 on my Intel X550-AT2 back to port 2 on my Intel X550-AT2, so the issues with achieving full speed links on this run with Marvell 88X3310-based modules are presumably due primarily to a combination of power limitations coupled with the inferior power efficiency of the Marvell 88X3310-based modules.)#3: Broadcom BCM84891-based modules are dramatically superior to Marvell 88X3310-based modules in certain applications.Yes, all of the Broadcom BCM84891-based modules on the market are priced at a significant (35–100%) price premium over the Marvell 88X3310-based modules, however these particular Broadcom BCM84891-based modules are one of the cheapest Broadcom BCM84891-based modules available.Furthermore, the Broadcom BCM84891 is well worth the price premium over the Marvell 88X3310 in situations involving:• Achieving 10G links on ≥30m runs of cat6a cabling• Achieving 10G links on runs of cat5e/cat6 cabling that are too long for Marvell 88X3310-based modules to reliably achieve 10G link speeds over. Note that in this case "too long" is often MUCH lower than 30m — for example, my use case is a link that should be somewhere in the ~15–20m range, and I've seen many other users online reporting similar issues (and similar resolutions!) at a very wide range of different link lengths.• Situations where module power consumption is a significant consideration. Note that Broadcom BCM84891-based modules are generally specified for a power draw of ~1.6–2.0 W for ≤30m links (or 2.0–2.5 W for ≤80m), while Marvell 88X3310-based modules are generally specified for a power draw of ~2.4–3.4 W for ≤30m links — this can be a rather dramatic (~17–41%) difference in power consumption for ≤30m links!• Situations where module temperature is a significant consideration• Situations where the increased fan noise resulting from the elevated module temperatures & power consumption would be undesirable, or where supplementary cooling would otherwise be required (e.g. with fully-passively-cooled hardware such as a MikroTik CRS305 or CRS309).One example of a situation like the last example is my use case for my CRS317. I have it located in my bedroom/office, and so having it frequently kick its (normally quietly idling) fans up to max speed (which is very loud!) for an extended period of time to try to cool down the overheating Marvell 88X3310-based MikroTik modules operating at 10G is obviously a significant annoyance.I even had to relocate the position of the MikroTik modules to ensure they were placed directly in front of the rear fans in order to increase airflow to them. While this significantly reduced how often & how long the fan would spin up to max speed, it unfortunately did not do so by anywhere near enough to make it tolerable.Yet the Fiber Mall Broadcom BCM84891-based module that is acting as the switch's uplink port (which is also in the absolute worst SFP+ port on the switch from an airflow point of view!) is running FAR cooler than the MikroTik module that sitting directly in the path of the fans (and therefore receiving FAR more airflow from them), even though it is operating at the exact same link speed, and is (at least currently) passing the exact same amount of traffic through it!Of course, if you're working with cat6a links under 30m with actively cooled host hardware located in an area where noise is of no concern (e.g. datacenter, MDF, IDF), and have sufficient port group power budgets, then the cheaper Marvell 88X3310-based modules are obviously going to be a better fit for you.#4: The price is right — and it's available right here on Amazon.com with fast and free Prime shipping!The only possible downside I can think of is that the multi-packs sold on Amazon currently aren't Prime-eligible and have extremely long shipping windows, however I suspect part of the reason for the lengthy shipping window is pandemic-related shipping delays, and it's possible that the seller may begin to stock those (and/or other multi-pack options) in US warehouses down the road. Regardless, this minor downside is not something that I care much about, but I thought it was still worth mentioning.Overall, I am EXTREMELY satisfied with these modules, and plan to purchase more of them in the near future!

Works very well for a month in a Freebox Ultra a router from a french isp connected to a switch Trendnet TEG-S762 r2 with Cat5e cables up to 20 meters in the walls at 10 Gigabits. The temperature is low and it can be touched safely during operation.

Got the intel flavor first, my es16xg was fine with it, but not my er8xg. Got the Cisco flavor instead, both router and switch are happy with it. Cherry on the cake, the sfp does report some dom/ddm info (like sfp temp).Also, do yourself a favor and spend a bit more dough to buy the 80m flavor (uses a Broadcom chip). The 30m version of this sfp uses a Marvell chip, it’s finicky, and it runs bloody hot (the same goes for all other 30m 10baseT sfp, not just this brand).

Buen día lo instalamos en switch ARUBA y lo detecto sin problemas, excelente producto

Bought this a month ago to work on my Netgear switch. It worked well for about a month, but as of today it has died. The SFP+ port doesn't even acknowledge the device (light up). I've confirmed it died by switched it out for another which lights up and provides connection

I bought a pair of the Fiber Mall Cisco compatible SFP-10G-TS-80 10Base-T:80m version to link two buildings of my house together at 10 gbs (gbe actually) over a 60+ ft run of Cat5e ethernet cable where a fiber run is just not possible. I placed each in the outside SFP+ port of 2 MikroTik 5-port Desktop Switches (4 SFP+ ports each CRS305-1G-4S+IN)—I put a 10Gtek DAC in each SFP+ port closet to the built-in RJ45 1 gbs port to allow the most amount of cooling for the Fiber Mall RJ45 SFP+ transceiver. In this configuration under virtually nil traffic, both Fiber Mall transceivers reported a temperature of 44-46C.Because all reports indicate that the 10 gbe SFP+ RJ45 to Copper transceivers can exceed 90C with normal traffic, I mounted a 120mm Noctua NF-P12 fan to the top of each MikroTik Switch with a minimum amount of heavy duty Velcro blowing down into the switch. Then I removed the old 1 gbs copper link between the houses and allowed the 10 gbs Fiber Mall/MikroTik/Noctua unit to handle all the traffic between the houses (a variety of servers, cameras etc). With that configuration both Fiber Mall transceivers report 29-31C all the time.It appears that using the Fiber Mall transceivers, and the rest of a configuration similar to mine, it is possible to achieve a 10 gbe link over Cat 5e for the recommended distance without having to deal with the usual high temperatures of such transceivers. I'm wondering if I could dare to add a conventional laser/fiber transceiver in the SFP+ port next to the DAK without heating the Fiber Mall transceiver too much. Nice job Fiber Mall.

Used it to connect my ubiquiti switch to my Mac mini 2018’s 10gbps port.

I had 2 modules that randomly stopped working after about a month. The Amazon warranty ran out, so I tried fibermall's warranty. They told me to ship the modules to an address in China that didn't exist on Google maps; customs in my country uses google maps to determine where something is meant to be sent, so I had to try my best to parse the address they gave me. At the end of the day, I don't think they received the modules. Regardless, they sent me replacement modules that I would never see due to a package thief. The funny thing is that I live in a good neighbourhood and have never dealt with package thieves in my 10+ years living here. In total, I spent about 1-2 months waiting for replacement modules that never arrived. I then purchased new modules from FS and have had no problems since. You pay for these modules with your time in the unlucky event that they stop working.

This has likely caused problems in my network when getting downstream connection from a 10GbE device to 5GbE which significantly slowed down the connection to even less than 200mbps in the 10GbE device. I have to force the 10GbE device to operate at 5GbE to avoid this drastic slowdown to have around 3.8 GbE afterwards.
