Is it possible to have 2 optical lines on 1 SFP Mikrotik?

Question

Mikrotik

Good day! We want to get confused with optics on one object. The length of the line is planned to be about 200 meters and about 200 -250 Mbit of traffic inside. Now there is copper that can not cope. So there is an idea to use optics. As equipment, we plan to use
CCR1009-7G-1C-1S + as a central node (office server rack) with the S + C61DLC10D module (it seems like DUAL LC, as far as I understand, you can have up to 8 lines)
CSS326-24G-2S + RM as reference nodes (workshop) with the same module. Clients will come to them and run away to the office with optics.

Tell me if it will be possible to connect this iron with optics. As far as I understand, this CCR has only 1 SFP + port, will it be possible to push 2 switches into it with this module. I strongly ask you not to kick, we are working with optics almost for the first time, a whim of the client. Constructive criticism and advice is always welcome

Answer 1

A good option:
A cable from each point to the office, in the office there are microts with a bunch of sfp (they have those). Connect everything and rejoice. Works great, good reliability.
The option is normal:
Cable from the office in each direction, there through mikrotiki with the help of sfp you make an entrance / exit to the next point. Everything is fine too, but the "transit" nodes will be critical points, the node flies out and everything behind it, respectively, will fall off.
Regarding sfp:
1) Distances are written for a reason, your S + C61DLC10D module is 10 km away and at that distance it and / or it will be burned by the same modules. Take shorter distances.
2) Take the simplest modules.

Answer 2

Logically, an SFP port is no different from a twisted-pair port.
So no, there is only one line to one port.
To connect additional optical lines, you can use media converters.

Answer 3

1 SFP port = 1 RJ45 port. Just a different connector.
1-2 fibers in SFP are not 2 channels, but one reception, another transmission, sometimes both the transceiver and the receiver work on the same fiber.
For video surveillance purposes, I would pull 2 ​​fibers from each point to the office.
Ideally, you can, say, take a 4-8 fiber cable and weld it with couplings at each point, bringing out 2 fibers from both sides.
Well, in the office, any L2-L3 switch for 16+ SFPs, or if there is enough money, then SFP + to lay the possibility of switching to 10G

Answer 4

It will work. To bring 8 lines into one, the CWDM-MUX8A sealer is used, which is connected to the central switch by eight CWDM modules with different frequencies.
At the same time, OADMs must be installed on the peripheral switches, which remove the signal of the required frequency from the line and send it to the CWDM module.

Answer 5

S+C61DLC10D

This is a WDM module paired with a WDM MUX, take the usual S + 85DLC03D for multimode or S + 2332LC10D, micros are also not particularly demanding on SFP, you can look towards Ubiquity modules, they are cheaper.

2 links 10g cannot be connected to it, put something like crs309/crs317 in front of it, or look towards ccr1036-2g-8s+
