Re: Low cost WDM gear

You can do ~500km without inline amplifier sites using EDFA+Raman+ROPA, but you are going to need some serious optical engineering to make that work. The more standard way to do it is amplifier sites every 80-100km for EDFA. If you are doing 10GigE you will need to allow for DCM also. On Sat, Feb

If you pay close attention to the Spec Sheets, on power output, insertion loss, sensitivity, and do the proper calculation for your link, then using anyone's products, passive or active will work unless the devices do not meet specified specs. If you don't do your homework, cals on the design,

Multiple 10G, yes. I'll reach out to the vendors mentioned to see how they line up, but it looks like I need to look into amps for the passive gear. There's 8 huts between the two ends, so no shortage of opportunities to amplify the signal. I'll know more about that when I get the amount of loss

Re: Low cost WDM gear

Yeah, you can get up to 80km on a passive unit using SFP+ and up to 120km using XFP.  To cover the distance you are considering, you would need to insert an amplifier.  Depending on the number of channels you require, a passive solution with an amplified would still be less expensive than an ac
