  1. SFP-10G-LR Works with Cisco Nexus 5 Star Review

    Posted by on 08/02/2013

    The SFP-10G-LR definitely fit our needs. We needed a module that would work with our Cisco Nexus switches, but wouldn't run up the tech budget. This one certainly fit the bill. It installed very easily into the switch, and we were able to use it almost right away. FluxLight came through with the SFP-10G-LR.

  2. Data Centers Can Benefit from SFP-10G-LR 5 Star Review

    Posted by on 08/02/2013

    The SFP-10G-LR is a great cost-effective alternative to other modules. It provides really good performance great 10km range at a substantially cheaper price point than Cisco. Yet it still interfaces flawlessly with Cisco products. The single mode fiber and dual LC connections are also good features for our office.

  3. Great Long-Term Purchase in the SFP-10G-LR 5 Star Review

    Posted by on 07/26/2013

    For long-term development, you need a durable transceiver like the SFP-10G-LR. This is the kind of equipment that won't let you down or hurt you. There's great compatibility with this particular model, as well. If you're thinking about long-term investments, this is the real deal.

  4. SFP-10G-LR Has Long Link Length, High Compatibility 5 Star Review

    Posted by on 07/09/2013

    I'm really happy I went with the FluxLight version of the SFP-10G-LR. It's still manufactured by Cisco, so I know it's quality, but it was cheaper than the name brand. I really like the SFP-10G-LR for its long range (10 km) and single mode connection. Single mode is pretty standard, so we're almost guaranteed compatibility when we get new equipment.

  5. SFP-10G-LR is Single Mode and Long Distance 5 Star Review

    Posted by on 07/03/2013

    For the price of the SFP-10G-LR, you can't beat its range. It can operate at over six miles, providing great data rates and tons of connectivity. It's compatible with Cisco products, though it's far cheaper than those. Our IT person had no issues implementing it into our system. Great for troubleshooting!

  6. Dual Connectors, Tough Casing on SFP-10G-LR 5 Star Review

    Posted by on 07/03/2013

    I'm really impressed with the durability of the SFP-10G-LR. Lots of components of our computers have fried, but the SFP-10G-LR that was attached to those components is just fine. This is a great SFP+ transceiver that has served us well for quite a while. It's an off-brand, but that doesn't stop it from working really well.

  7. Extraordinary Pricing on SFP-10G-LR 5 Star Review

    Posted by on 06/12/2013

    I thought the price on this SFP-10G-LR had to be fake. I saw it on Amazon for close to $1000, so I was absolutely amazed that FluxLight could afford to offer this for so cheap. And the SFP-10G-LR is a fine product, too, capable of up to 6.2 miles of distance and speeds of 10 gigs per second. A good SFP module from Cisco, at an unbeatable price from FluxLight.

  8. Cannot Believe SFP-10G-LR is This Cheap 5 Star Review

    Posted by on 06/11/2013

    The SFP-10G-LR is a professional piece of equipment, so I was really surprised to find it for this price. SFP+ modules are normally way more pricy than this, so I was really expecting some sort of drop in quality. I was disappointed; I can't tell the difference between this and more expensive brands. FluxLight deserves some commendation here.

    Posted by on 05/26/2013

    I cannot believe I saved almost $300 on this SFP-10G-LR module. Getting this here was the best decision I could have made, and I would recommend it to anyone. I am so happy with this purchase!

    Posted by on 05/19/2013

    This Fluxlight module was RIDICULOUSLY low priced!It works perfectly and does exactly what it is supposed to. I don't think I'll need to use the warranty but it is nice to have just in case. A fantastic buy!
