Fast delivery and top quality product

I'm looking to implement CWDM links on dark fiber.
Can you tell me which SFP+ 10G modules for Cisco to order to get the right TX/RX? (4 links with différents wavelenghts)
I can't find the right part numbers on your site.

Thanks for your help

Works for my projects
A CWDM solution could easily cover the distances involved.

About two weeks ago, we were preparing our purchase list including some SFP modules, fiber jumpers, panels, and CWDM MUX/DEMUXes. We'd love to buy all of the components from FS, but I was still uncertain whether the 9ch Single-fiber CWDM MUX/DEMUXes would fit our demands. So I turned to FS's account manager for help. The AM provided me with a solution of deploying 9ch and 2ch CWDM MUX/DEMUXes based on our case. The maximum link loss was within the range of acceptance. Their detailed product list covered EVERY item description and some remarks for my reference, which impressed me indeed.

We need a 14km connection between two sites. We wanted to adopt a WDM solution, DWDM seems not cost-effective due to our tight budget. After discussing, FS's technical team recommended us with another CWDM solution including the following components: 9ch CWDM MUX/DEMUXes (1270-1590 on side A and 1290-1610 on side B), customized OEO, FMU Chassis, and some matched modules and cables. The solution they provided was rather exhaustive, which solved our problems effectively and meet our 14km-transmission requirements. Thanks for your tech support again!

This MUX is customized according to my requirements strictly, perfect!
