SFP 1.25GB/S 1310NM ZX-SM-40KM

Thu Jan 27, 2022 4:49 pm

Hello,

I've a fiber connection between two endpoint.
On one side I've my CCR1036-12G-4S. On other side a third party router that I cannot manage.
Fiber leght is about 35 Km.
On other side there's a SFP 1.25GB/S 1310NM ZX-SM-40KM.

Which module could I use on my CCR1036-12G-4S?
I tried S-31DLC20D but TX power is too low.
Please don't suggest to switch to 1550 nm. Other side router/module cannot be changed...

Thanks for you help.

Would recommend bookmarking the following: https://help.mikrotik.com/docs/display/ROS/Peripherals
Great Wiki that will give you a quick idea on what 3rd party modules should work with Mikrotik devices, the unfortunate thing is that I went through each of the SFP modules that were 1310nm and none of them were rated close to 40km.
I did notice that at the bottom of that wiki, Fiberstore looks to have a SFP+ modules rated at 40km but I wouldn'd be able to say if they play nice when the speed is set to regular SFP settings.

https://www.fs.com/de-en/products/15686.html should fit the bill. 40km@1310nm.
