Optical Fiber Communication with Arduino | Arduino-Powered Data Transmission with Fiber Optics

[@DArnez-c5n]

OMG this tutorial is super crazy! Thank you you have opened the door of optical communication just now for me!

[@PawełRapta]

Very good video, it is rare that people are describing electronics details like that in arduino videos. I appreciate that :)

[@electronicstree]

Thank you so much! I'm glad you found the video helpful.

[@Chris-ik7st]

wow. best instructional video i've seen in a very long time. bravo

[@Bravo_Ventures_LLC]

Beautiful. I love the detailed explanations.

[@flavor_townn]

This was an awesome tutorial, thank you so much!

[@ajredband]

Hi, is it possible to have both emitter and receiver connected to the same Arduino unit? I am trying to connect 3 different types of fiber sensors and one of them is through beam. Thank you for all the information.

[@electronicstree]

Yes, you can

[@ajredband]

@@electronicstree thank you, I will go ahead and use this as a reference.

[@elektocity6482]

can optical communication do 2 way comunication betwen 2 arduino just using single core optical cable ?

[@electronicstree]

The answer is no, and the reason is that with this limited hardware setup of an optical transmitter, receiver, and Arduino, you can't achieve bidirectional communication. For this purpose, you have to choose BiDi transceivers for your two-way communication with a single optical Fiber cable.

[@CraigHollabaugh]

At 9:34 you mention frequency compensation, then at 12:06 you say the diode D1 protects the TTL data from reverse voltage, don't quite understand, reverse voltage from where? Does I suspect D1 does both waveshaping and protection, is this correct? Otherwise, exceptional video, thank you.

[@electronicstree]

The reverse voltage here refers to the transient voltages or spikes caused by the SN75452B's switching activity. In this configuration, the diode is used to protect the optical transmitter from these voltage transients or spikes that may be generated by the SN75452B.

you can also transmit audio over incandescent lightbulb in room.

Hello Dr, I would like to make this project but if I finish this project how can i make it sending from device to another?

I didn't understand what you said. What is meant by sending from other device?

Could u make a video explaining a simple DIY protocol for a simple project like a coupled LED and sensor transmiting info between 2 arduinos, i mean, data structure for serial communication, error check etc

[@electronicstree]

Creating a DIY protocol for a project like this is quite achievable! We can design a straightforward communication protocol utilizing serial communication, implementing error checking mechanisms to ensure data integrity between the two Arduinos. I'll be sure to incorporate this into the upcoming videos.

of course

si i have question : how to connect SFP modul with arduino?

[@zhanaroo]

What i can use instead of TX and RX HFBR? More cheaper?

[@electronicstree]

Sorry for the late reply. You can use any TTL-compatible module with Arduino, just make sure it matches the specs in the datasheet for everything to work smoothly.

[@alexforgosh2397]

Hey! Fantastic video, I was wondering how/if it would be possible to modify this design to work at 6.2 MBaud?

[@electronicstree]

If you're working with microcontrollers, this transmitter and receiver setup should work fine. To answer your question, you just need to adjust the values of the passive components for the transmitter. For the receiver, if you're looking at speeds above 5Mbaud, you'll want to swap out the HFBR-2412 with another model like the 2416. Check out Broadcom's Applications Support Guide for all the configuration details you need.

[@alexforgosh2397]

@@electronicstree Thank you! I will look into this, do you have sample calculations for how you chose your own passive component values?

[@Wolf_of_Tarkov]

Could you provide the schematic for the Receiver circuit? I went on all the Arduino links you provided but I couldn't figure out the connections to the LCD. Apologies if I missed it! I really want to try this circuit out. Thank you!

[@electronicstree]

I have provided the receiver schematic in parts 4 and 5. All you need to do is connect the TTL data out pin to the Arduino RX pin. As for the usage of the LCD, I assume Arduino users already know how to use it because it's a basic thing.

[@rodrigoc.goncalves2009]

Very interesting! I read something about drones used in the Ukrainian conflict that use one optical fiber cable without buffer not jacket, for bidirectional communication. Do you think this is realistic? Having bidirectional comm in just one cable, and not having an outer layer

[@electronicstree]

Yes, it’s definitely possible to use a single optical fiber for two-way communication. This is achieved using special technology that allows data to flow in both directions simultaneously. To make this work, you’d need BiDi transceivers designed for two-way communication over a single optical fiber cable. As for the lack of an outer protective layer, I’m not entirely sure how that would work with drones. I have no idea how they’d handle an unprotected optical fiber. It’s possible the design includes other ways to safeguard the fiber, but I’m not sure how common or practical that would be.

bro, can the 2.4ghz signal be converted to this module... so that I can transmit the 2.4 signal to many routers via fiber... to act like OLT...

[@electronicstree]

no

[@Sanggar_waringin]

@@electronicstree oh okay... for the signal you transmit using this method, it's a digital or analog signal... bro

You can transmit both analog and digital signals using this method. In the demonstration, I transmitted analog signals.

[@emir4707]

​@@Sanggar_waringinMaybe with esp32 you can transmit and recieve tcp packages

[@darshanpanchal3046]

can i use it as for SPI communication?

[@electronicstree]

If you want to use the SPI interface, you will have to use the number of optical transmitters/receivers and optical fiber cables accordingly to the SPI lines. This is because it requires more signal lines (wires) than other communication methods. Essentially, you have to convert every electrical signal line to a light signal and then convert these light signals back to electrical signals. Therefore, this approach may not be suitable.

sir , i have question : how to connect SFP modul with arduino?

[@electronicstree]

Which specific SFP module are you looking to connect to the Arduino?

[@HadjerElHamlili]

@@electronicstree i don't know yet, i'm going to use my single -mode fiber optic system , arduino uno, two SFP modules on both sides of the fiber optic

[@Mistrzu220]

The only problem I see here is the price and availability of TX diode HFBR-1414Z and RX photodiode HFBR-2412Z. Currently, prices for these components are around $50. However, the video is very interesting!

[@electronicstree]

The prices I found range from 7 to 10 dollars for each module, while some sites offer them at 20 to 28 dollars. If you find any, you can use any TTL-compatible modules according to their data sheets.

[@Mistrzu220]

@@electronicstree I decided to use a different technology for my project - toslink. RX and TX (DLT1160A) cost me ~$2. Thank you for the inspiration.

Hi bro How to send 3 sensors at the same time ?? Thank you

[@electronicstree]

If you are using UART communication, you can use three modules. You can use Arduino Mega, which has multiple hardware UARTs, and for Arduino Uno, you can use SoftwareSerial. As for ASK modulation, I'm not sure, but the RadioHead library may not support multiple transmitters and receivers in a single network.

Building a fiber optic splice tool with Arduino is tough because it needs precise equipment like fusion splicers to accurately join and fuse optical fibers. Arduino isn't well-suited for such a complex job.
