Cisco SFP-10G-LR-S Compatible 10GBASE-LR SFP+ 1310nm 10km DOM LC SMF Transceiver

I bought 10G LRs to connect two buildings, they are plug and play, and work well with Cisco and Juniper equipment. The transmission rate is as expected, and the quality is generally reliable.

The 10G modules arrived on schedule with intact packaging. I plugged them into my Cisco switch and the connection came up normally. I will come back if I need more optics.

I have purchased several of these for my HPE switches and they work very well with no performance or compatibility issues so far. Great value for money. I believe I will be placing another small order in the next few days for a few more modules that we are missing.

Simple but effective.Thanks to the enthusiasm of my account manager, whose name is Amanda, even for such a small order, I must say that the order received exceeded my expectations.This was my very first order with QSFPTEK and I will be keep coming back for more in future.

Jusqu'à présent, il n'y a eu aucun problème de compatibilité et je les utilise sur une assez grande variété de matériels. Ils semblent avoir des performances cohérentes (c'est-à-dire que plusieurs unités produisent des niveaux d'entrée/sortie cohérents).

Work greatly with my S5300-24T4X 24-Port switch with no troubleshooting, delivering full 10Gb stably, that's good for data center, cost-effective products I think.

Sometimes I can not control the switch well. The sales are always patient and get my problem solved quickly. With perfect compatibility, you can even use it for CISCO device. I think QSFPTEK is organized by a professional team.

We are extremely satisfied with the module's performance, as it worked flawlessly on our Cisco switches. We appreciate the excellent quality of the product and the exceptional customer support provided by the company. Moreover, we received the goods on time, making it a pleasant shopping experience for us.

This is my first attempt to buy from QSFPTEK. The product is surprisingly reliable, the indoor temperature in the computer room has been -3 ℃, and the performance of the module is very stable, which is good. QSFPTEK will be one of our equipment suppliers for another project.

Great price, fast shipping to Germany, efficient support and follow up, they helped me identify what I really needed at the best price. Great purchase, QSFPTEK is my favorite network equipment supplier. Thanks!
