What options are available for 40G QSFP+ and 100G QSFP28 for 10+ km links?
LR4 and weak ER4 (flexoptix were trying to get a 40km part out, only 25km has emerged so far) then you're into coherent stuff in a separate box (which per 100G doesn't cost a lot more than the ER4's)
I need stronger modules that can do more than 10 km without being extremely expensive. Or DWDM modules in the 1550 nm band so I can use external amplifiers.
We use 1310 amplifiers for now, originally these http://www.hubersuhner.com/en/solutions/cube-optics/products/active-systems/... but there is a fibrestore version too now https://www.fs.com/products/69350.html
Am I looking in the wrong place? Is this expected to be available in the near future?
Eventually there will be something once they can make it fit in qsfp package size and power limits. brandon
