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.

Quería comprar el Cisco 1000BASE-BX-U BiDi SFP para desplegar una red 10G. Encontré esta compañía en línea que era fácil de usar. Entonces me puse en contacto con el vendedor en esta empresa para ayudarme a terminar la orden. ¡Y ahora, el transceptor llegó en buenas condiciones!

¡Excelente!
Una buena selección de módulos SFP, excelentes precios y el servicio al cliente es amable.

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!
