New Solution: GPON/GEPON link with MikroTik Switch, RB2011UiAS-RM,hAP ac or hAP Lite AC as ONU/ONT
Here in this blog, we just give you a generalize idea about GPON/GEPON basic link with MikroTik switch as ONU/ONT to provide high speed internet access to many customers.
The basic structure of a GPON/GEPON link with new solution is shown in the figure below.
In the network diagram you can see that you can use the Mikrotik Switch,RB2011UiAS-RM,hAP ac and hAP Lite AC as an ONU/ONT to support more customers.In traditional GEPON/GPON network,we have to buy 1-port,2port or 4-port ONU and the ONU serves the customer according to the number of ports.For many customer`s connection you have to use many number of ONUs/ONTs.What is the solution for that?Is there any cost effective solution available?
What if someone use the same fiber infrastucture to provied the Wi-Fi connectivity to different building or office?
Solution: you can use your MikroTik switch with a PON module as an ONU/ONT.There are upto 24 Ports MikroTik switch is available in the market today with GPON/GEPON module.So instead of many ONU/ONT ,you can use just one MikroTik switch to get the high speed internet connection.
The basic components of GPON/GEPON link remains same like OLT,PLC Splitter, Fiber Cable but we have to just replace the ONU/ONT with the switch or other MikroTik routerboard devices to provide high speed internet connection to many customers.For that you need PON SFP Module which is compitible to MikroTik products.
Equipment Guide for the New Solution
I. Optical Line Terminal (OLT)
OLT is the heart of the Fiber-Optic network because the all the network management and configuration is done here. Generally, it is located at central office.
OLT in GPON acts as the network controller, which communicates with ONTs (ONU), which prevents direct interactions ONTs on the same GPON. The key features of OLT are:
Discovery process, which is continuously determining if any ONT’s (ONU) have left or joined network.
Registration of the newly joined ONTs & assigning of the varying amounts of upstream transmission bandwidth to each ONT (ONU).
Ranging process, which is calculating transmission time delay between an OLT and each ONT (ONU).
Time-stamped message generator, for global time reference purposes.

II. Optical Network Unit/Optical Network Terminal (ONU/ONT)
It is a CPE equipment used to converts optical signals transmitted via fiber to electrical signals. These electrical signals are then sent to individual subscribers. In general, there is a distance or other access network between ONU and end user’s premises. Furthermore, ONU can send, aggregate and groom different types of data coming from customer and send it upstream to the OLT. ONU could be connected by various methods and cable types, like twisted-pair copper wire, coaxial cable, optical fiber or Wi-Fi.
ONT is the same as ONU. ONT is an ITU-T term, whereas ONU is an IEEE term. They both refer to the user side equipment in GEPON/GPON system. But in practice, there is a little difference between ONT and ONU according to their location. ONT is generally on customer premises.

III. PLC Splitter
PLC (Planner Lightwave Circuit) Splitter is used for to split the signal at according to the splitting ratio to many customers. It comes with 1:2,1:4,1:8,1:16 or more splitting ratio. For selecting the PLC Splitter, first see that what is the maximum number of customers are supported by your GEPON/GPON OLT and what is the distance between the central office and the customer’s location? According to your network connection, you should select the splitter.

IV MikroTik Switch
The CRS125-24G-1S-RM MikroTik switch which is SFP PON Module compatible is shown in the figure. For the network connection, you have to configure the switch in bridge mode. After assigning the bridge mode to all the ports of the switch, you should connect the SFP PON module on the SFP port and apply the fiber connection from the PLC splitter. Then do the configuration in the GPON/GEPON OLT according the OLT management.
You can provide high speed internet connection to many customer’s compare to single ONU.This is the main advantage of using MikroTik Switch.Sometimes you do not want to replace your MikroTik network deployment and want to get the high-speed internet then at that condition, you can use this type of solution of combination of GEPON/GPON+MikroTik Switch.

VI MikroTik Routers (RB2011UiAS-RM/hAP ac/hAP Lite AC)
If you want to use the Wi-Fi connection for the office or home, you can select the MikroTik routers which are shown in the figure. Per the PoE-In and PoE-Out, you should select the routers.
As shown in the diagram, the RB2011UiAS-RM router has PoE-Out port so it can power the other PoE capable devices with the same voltage as applied to the unit. So, with this router we connect the hAP Lite AC which has both PoE-In and PoE-Out ports. By cascading connection of this hAP Lite AC, we can get the Wi-Fi coverage in the building at different offices. So, you can connect the hAP Lite AC per the range you want to cover.
In a same way, you can use hAP ac in the cascaded connection through PoE-Out and PoE-In ports to access high speed internet at any location or area. But before that you just need to attach the PON SFP Module to the switch or routers which is compatible to the router board devices.
