I need some SFP BiDi modules to be used on my Cisco SG550XG-24F and Cisco SF350-24P switches with a transmission distance of 30km. The AM recommended this transceiver with a link distance of 40km for me. After receiving the products, I plugged the modules into my Cisco switches and did the compatibility test, they worked well as advertised. Currently, the modules are working well on my network switches, and there were no errors that occurred on my switches. Very nice transceivers for me!

I bought cables and transceivers several times here. I like the services and products of FS very much. The 1G modules were just what I wanted for my Cisco switch. I inserted the SFP BiDi transceivers on my switch, they were recognized immediately. Works perfect as usual.

I received my items quickly. Customer service is excellent. The items received were accurate. I will definitely shop with FS.com again. Thanks again.

I have an urgent project and need some 1310/1550 and 1330/1550 BIDI modules. I tried to find them from several stores, but didn't succeed, same as Fiberstore. I consulted my sales and told her my demands, she told me they can customized the wavelength I need. And the lead time for customizing was not very long as I thought. Now, I have received my bidi modules and tested them, they are running error free. They really helped me a lot for my project! Thanks!

It's my first time to buy 1G BiDi SFP 1310/1550 40km transceivers at FS.COM. At the very start I was a little worried about the quality, but I browsed on their webpage about the test assured program. They really have the very professional test center. I find my Cisco ASR 9000 Series, too. So I placed the order without doubt. The shipping time is also fast and I'll looking forward to receive my parcel.

I wanted to buy the Cisco 1000BASE-BX-U BiDi SFP to deploy a 10G network. I found this company online that was easy to use. Then I contacted the salesperson at this company to help me finish the order. And now, the transceiver arrived in good condition! Thanks a lot.
