FS（飞速） SFP-GE-BX40 BiDi SFP千兆单纤双向光模块 1310nm-TX/1550nm-RX 40km

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.
