The 100G SR4 optical transceivers are used for the 100G DWDM solution established by FS technicians two months ago in our plant. Only 4 channels were put into service and the rest reserved for future expansion. All went well. Moreover, the subsequent expansion is easy to figure out by ourselves. Brought home the right amount of coherent modules and 100G SR4 optics as the technicians instructed. Things now go smoothly as they did at the very beginning. Very good service and quality.

Want to find transceiver modules for Juniper MX960 and QFX5200. They recommended this 100G-QSFP28 and customized to make it work. Good value as before and haven’t charged me an arm and a leg. Never let me down.

It’s not my first time dealing with this company but i’m just satisfied as usual.
This time we are upgrading our 40Gb switch to a 100Gb switch (Edgecore AH-7712-32X) and needed to order a bunch of accessories for it.

To start off, we're going to want the following transceivers, cables and management tools, and everything needs to be compatible with 100Gb/25Gb links.
2 x #34684 - 1U Rack mount fiber enclosure
2 x #68399 - MTP-8 /MPO 100Gb->4x25Gb Breakout Cassette
3 x 100Gb SR 850nm transceiver, compatible with Edgecore switch and supporting 4x25Gb optical breakouts
8 x 25Gb SR 850nm transceiver, compatible with Mellanox ConnectX-4 NICs
8 x LC cables, 2 meters
2 x MTP cables, 3 meters
2 x MTP cables, 2 meters
1 x set of cleaning tools for LC/MTP cables & transceivers
1 x microscope for LC/MTP cables & transceivers

As for high speed networking I usually want to use something with fancy name-brand but FS has really surprised me with their quality. The transceiver is sturdy looking, easy to plug in, remove and seats in the QSFP28 slot firmly. I am using 2 of the 100g sr transceivers on my Edgecore switch, with each breakouting into 4 25g to connect the Mellanox NICs. Works like a charm without any problem so far. These qsfp28 modules are really one of the most important parts in my network as the uplinks from the Mellanox NICs are all connected to them.I have used a bunch of their QSFP+ in an old 40G dell unit and they have had no issues for over a year: no dropped connection, no spotty performance. Can’t tell the difference between these and original modules based on using experience. The reality is that you could spend a ton of money on a name-brand version of these optics, but there’s really no need. So I would just stick with them and use them in production with no doubts.
I’m confident they’ll stay working for years. It won’t break my bank even i buy a handful on hand just in case.

The only thing to be aware of is the compatibility as it is a customized item. Could look up the working/non-working module support thread for your device or ask the team what will work with your equipment before ordering. I bet you will get fast response. Would definitely recommend the company with confidence.
