Fiber optics: Receiver/Transmitter

You will end up with a larger cost using fiber optic. Unless you find a discarded complete communication system (transmitter, fiber and receiver), to build it yourself is labor intensive. I have built one but with fiber already having the ends (mirror) polished. Not to mention the serial protocol necessary for the communication. I think that there are serial systems, already built, that will make your computer connection:

-RS232

-FireWire

-Ethernet on the same router

-Bluetooth (wireless)

-etc...

i know other ways for connection....

but i wana do with fiber...

how much cost????

iis u able got total data without any loss using fiber????

Why not use some IR transmitters and receivers connected by a length of Plastic Optical Fiber.

Designing your own fiber optic full duplex transceivers or building one from an available design are both expensive and time consuming choices (not to mention very challenging). As others have said it's much cheaper and faster to buy an existing product. I suspect you want to use it for secure reasons or to pass through an area of high electrical noise where fiber is immune to interference. If your application is security, I hope you realize that fiber can be tapped via microbending and data extracted. Even though you use fiber there are ways to eavesdrop on PC activities electronically (via conducted or radiated electromagnetic emanations) unless you have Tempest engineered communications systems to block interception of data. Good luck

You want cost but you do not provide enough information for what you really need it for.

Fiber optics is not that simple. There are different types; multimode or singlemode. Each has it's own advantage/disadvantage. Which will you be using? What is the distance between the fiber optic transmitter/receiver? Typically single mode is more expensive but covers greater distance.

There are more questions but this could be a start.
