Cisco C58 DWDM-SFP10G-31.12 Compatible 10G DWDM SFP+ 1531.12nm 80km DOM LC SMF Transceiver

Wide range of products for selection, for the first business, I ordered the parts with the help about a detailed introduction, everyone can do it. the compatibility is OK with my device, I was deeply impressed with their prices which are cheaper than all parts I bought before, will contact them for more plans.

I needed to upgrade my network to handle the increased traffic and data requirements of my business. The SFP+ optical module from QT was the perfect solution for this, works with no problem, and is compliant with the SFF-8431 MSA and SFF8432 MSA specifications for high performance. I'm very happy with my purchase and would recommend it to others.

I purchased the optical module to improve the speed and reliability of my network, and I didn't experience any data loss or dropped connections. The only point that needs to be noticed is that the module gets a little hot while working, but it makes no difference with the operation, it is OK.

Good deal with QT, thanks for the Recommend of a 10g transceiver at a reasonable price, it plays a role in my 80km distance Haul DWDM Solution, paired with the SMF Optic patch cable enables high-density solutions, what’s important, no issue reported so far, high Compatibility it works.

Helpful and knowledgeable sales team. I had a few questions about the compatibility of the module with my equipment, and they were able to provide me with detailed information and help me find the right module, quicker shipping process than I expected, arrived last Monday and is still in the testing process, no operational problems found at present.

Perfect products drive me to leave a comment, though this is the first business with QT, I am sure it would not be the last one, they did everything as described, with fast shipment and professional technology support which greatly satisfies me, what’s important, the module runs with high performance without error, well done.

Once again, QT bring me great surprise with excellent products and kind customer service, as soon as I got the product it was plugged into the CISCO switch and recognized in a second. It is the same performance on another brand device, so the compatibility is perfectly OK.

The package I received was defective, probably bumped during shipping, resulting in a very visible mark on the module. The good thing is that they act quickly to replace it after getting to know the situation, and it is running well now, a trustworthy merchant.

Still needs to be tested for some time, though received this switch a month and no case happen, as a big investment for me, I had to make sure everything was okay. will come back to comment after a long term testing.

Fantastic product, it is designed with a nice appearance with good materials. At the same time, the quality is also OK, with no abnormalities so far, I really like it.
