Understanding Wavelength Division Multiplexing

when you have implemented WDM devices on a fibre optic network. it turns out that we can increase the throughput capacity of existing bandwidth with a MikroTik router curious? please follow this video to the end and for those of you who haven't subscribed yet, please subscribe and click the bell too. so you don't miss our latest videos WDM or Wavelength Division Multiplexing is a technology that allows us to transmit several wavelengths (Î") or different colours in the same medium What does this WDM scheme look like for the transmitted media? For example, this device in front of us, the media only needs two cores. an example of this tool that we have is 4 Channel CWDM What is the same media? This is what is called the same media. there is TX and RX here Where is the different wavelength (Î")? the different wavelengths (Î") are here each of these ports has a different wavelength (Î") This is the device used to send, and there is also a device used to receive. one port is used to receive from the other side of the WDM device then for these ports it must match suppose port1 here uses wavelength 1 in the other WDM device must also use the same wavelength1 to send it only takes approximately two cores using the CWDM device that we have but for distribution to the bottom, or towards client devices, it requires a lot of cables or adjusted to the needs of the client devices. here if you check there are 4 channels if one port needs two cores, it means there are 2 * 4 = 8 cores we need 8 cores to connect to the network below then for the connection between WDM devices that we use now support for distances up to 20KM for this distance we only need 2 cores these are the specifications of the WDM device we are using now which can transmit several different wavelengths (Î") simultaneously in the same cable media. The advantages of using this CWDM device or WDM technology are we can increase the existing bandwidth capacity so if we usually transmit normally from router1 to router2 using 1 cable with SFP with WDM technology we can increase again For example, if the SFP port supports 10G dual-core, we can increase the bandwidth capacity to be even greater. For the CWDM device that we use, this 1port supports 10G connection. so in total, it can pass up to 40G connections. and we can send that 40G bandwidth just through this dual-core cable. so that's what it means to increase the capacity of the bandwidth. so the use of WDM technology can save the cable infrastructure used, especially for long distance connections. for example, the CWDM device that we use now supports a distance of 20KM. when we ee using this CWDM device for a 20KM distance cable connection we only need a 2 Core cable. but for the bandwidth capacity, it can be bigger. because if we only use a two-core cable and one SFP port, it depends on the specifications of the SFP port and SFP Transceiver. but with the use of WDM technology we can improve again. for example, here the CWDM device supports approximately 40G. From where, from this one port each, it supports 10G. In total there are 40G It's very interesting to use this WDM technology. next we will try for the topology for the example topology we have implemented WDM devices on both sides we want to utilise it, but not use all these ports we want to utilise it to increase its capacity because of what? when we just replace the SFP Transceiver in the CWDM device which by default uses 10G we want to upgrade it to 20G or above again for SFP Transceivers that are specifically WDM with the appropriate wavelength, it's a little difficult to find. We can utilise the empty ports on this CWDM device. and then we can do Bonding Bonding is a technology on the network that allows us to be able to aggregate several interfaces into the same virtual interface. What does it do? its function is to increase bandwidth capacity or be a fileover method so the experimental topology will be like this, and the solution we can do Bonding next we will try to configure bonding on the WDM network we will do the configuration on the WDM device, on both sides of this he also uses a router what router? here using a router with the type CCR2216 the first one here I have given an identity to the router to make it easier we will remote R1 first for the first one we make sure for all the interfaces are running this is the interface for connection to R2 or to the other side, this is already running then to create Bonding we can go to the Interface menu then find the Bonding tab here we can create the bonding configuration we add here yes well then we from the general tab here here we click bonding well this we we enter which interface we will do bonding on or interfaces that are connected to the WDM device. here we click the down arrow to add more these sfp28-1 and sfp28-2 interfaces are connected to their WDM devices for Mode selection, because we use routers on both sides and both MikroTik products we can use Mode=balance rr then we select Transmite Hash Policy=layer 2 and 3 we Apply and click Ok okay there is already an R (running) flag here, we can check in the interface menu for the bonding interface has been made, then we can give the IP address with Address=10.1.1.1/24 we set the interface parameter to Interface=bonding-R2 click Ok okay it works this is for the bonding configuration on R1 like this, quite easy then we'll configure the R2 device make sure the interface that leads to R1 is already running like this, there is already a caption these two interfaces that are under the WDM then we go to the Bonding Tab, we configure bonding the same way as the previous one in R1 we add the interfaces from R2 that are connected to the WDM, namely sfp28-1 and sfp28-2 the mode is the same i.e. Mode=balance rr with Transmit Hash Policy=layer 2 and 3 the configuration should be the same on both sides of the router we Apply and click Ok this is already running, we try to check in the Interface List menu this interface is already visible then we add the IP Address if so we can remote Sorry, we can do Ping test Let's try the Ping test first towards R1 from R2. Ping test has run and succeeded that's it for the configuration, easy yes we will try to do the next test the test we will use the Traffic Generator for the template this is already suitable so, we only need to use it we test with Traffic Generator for the bandwidth on each SFP port is 10G so if for testing needs the total bandwidth that can be passed is 10G + 10G = 20G we will try to pass 20G or 20000Mbps traffic for the TX Template parameters I have adjusted next we click Start for this test I activated the Traffic Generator from R1 then we will check in the Interface menu on R2 for the bandwidth that he receives it reaches 19G or close to 20G so like that, the configuration is very easy for this experiment we use routers on both sides if you do bonding and on one of the routes do not use a router in this experiment we use routers on both sides if in network conditions you use a router and switch then you can use Bonding with Mode = 802.3ad like that for the configuration, quite easy here if you look at the bandwidth capacity this SFP interface has a capacity of 10G and we bonded 2 SFP ports to the WDM device. 10G + 10G here the result can reach 20G for this experiment we use routers on both sides if on one of the sides it does not use a MikroTik type router, we can use 802.3ad Bonding Mode if you are interested in learning more about WDM technology, or fibre optic technology. you can join our training, Citraweb Fibre Optic Training.
