1. I have one mikrotik server-1 (CCR-1009-8G-1S-1+) in my switch room.
2. I have some clients which is connected directly from my switch room via 4 km fiber optic cable.
3. Now I have setup a new mikrotik server-2 (CCR-1016) in my switch room.

Now i want to connect some clients from server-2 via same fiber optic cable. I don't want to lay new cable again. I don't know the solution. Can anyone help me to solve the issue.

Thanks in advance

i think you need a manageable switch

Mdsekawsar, if I understand you correctly you have an existing fiber cable run to 'x'. 'x' is where a number of users are at. (over simplification - I know) You want to be able to connect all of these users to your network without having to run individual fiber cables for each user.

If I understand your issue correctly; you will need a switch that accepts fiber via an sfp. Mikrotik has some and so do many vendors.

Can you let me know if there is more to the puzzle so we can try to assist?

If the switch is managed (as Chechito wisely suggests) then you can put customers' circuits into two different VLANs, and then map vlan100 to server1 and vlan200 to server2, for instance.

This won't give you more bandwidth on the fiber itself, though. You could use CWDM passive optics and put different customers on different wavelengths, which would give you up to 8x reuse of the same fiber, potentially.

This would require a splitter at the head end and at each customer site, as well as different wavelength SFPs for the customers where you want to use different wavelengths.

Thanks Dear,

Lets make clear about the requirement. I have 7 users @ the end of my fiber optic connection. OK. Now from user 1-4 will connect to Mikrotik-1 Server and user 5-7 will connect with Mikrotik-2 server. Hope everything is more clear now.

Thanks in advance

Is it safe to assume that you already have networking gear at the end of the fiber where the users connect?

If so, then you should be able to setup a policy where traffic from group A goes to server A and traffic from group B goes to server B. If you don't have any gear near the users, then you will want to follow chechito's advice and use a managed switch/layer3 device.

Are they all in the same network/vlan?

Do they need to be separate - aside from server access?

Thanks Dear,

Nop, they all are not in same network/VLAN.

Yes, I need to be separate - aside from server access.

Then your solution is easy - for each customer that you want to put on router2, remove their VLAN from router1 and configure it on router2.
Of course you'll need to make sure that the IP addresses for those customers also get routed to router2 if you intend to continue using the same IP addresses for the customers you're moving.
