Recently our ISP extended a connection from the telecom room to another wiring of the building with 10Gb simplex (10 pairs). We need fibers (G.652.D) and transceivers to connect my Cisco switches from the telecom room. But we are not sure what kind of transceivers we should buy. So we sent a script to their technician group and ask for some advice on what type of transceivers we need from them. They are very considerable. Before making an order, they asked me if the FTTH system was GPON or Ethernet since always PON is applied in FTTH. I told them it’s Ethernet. Then they suggested me to buy this 10G SFP+ 40km bidi module. As the commercial temperature domain ranges from 0 - 70°C, which just meets our requirements. Really outstanding customer service. Any way, modules work great so far. Nice to work with FS.COM.

Received the items quickly. Plugged these Bidi SFP+ into my media converters and they just work well. And I like this solution so much as single mode fiber costs less than multimode fiber and simplex fiber costs less than a duplex. These modules save me a bunch of money. Great product and priced right.

These modules arrived very quickly and they were packaged in a secure way. At first, I had trouble with this module. But soon I solved it after I received instant service from the FS tech group. FS modules did a good performance.

Worked perfectly with my Mikrotik router to connect a couple of my home computers together. Power of 10gig Ethernet for the home us now easily within reach!

Fantastic, they just plugged into my 2 switches and now I have a 10 gig link between the switches instead of just a 1 gig link. It's been operational now for about a month. No issues.

Fulfills everything promised, excellent value.

Working fine and good price.

How to describe? Fast, reliable, inexpensive, rectangular shape, silver colour, two inches long, made of solid metal.... but enough about me, let's talk about this SFP. It's great.

Excellent Quality Products

No issues at all.
