The Serial Fibre Modem combines a CH340C USB-to-Serial bridge with a fibre receiver and emitter pair from Industrial Fibre Optics and it is the easiest way to start playing with fibre communication right out of the box. Simply insert a piece of fibre cable between the emitter and receiver, open a serial terminal at any baud rate up to 1Mbps, and watch your messages bounce back! Connect to another Serial Fibre Modem or use it in conjunction with our other Fibre Optics breakouts to create your own fibre links.
The Industrial Fibre Optics line of emitters and detectors are by far the most economical way we’ve found to create a simple fibre link between two devices. The IF-E97 emitter is literally just a superbright red LED in a fancy plastic module that makes it easy to insert a piece of optical fibre and lock it in place. On the other end, the IF-D96F is a 5v TTL phototransistor in an identical enclosure. Connect the two with a piece of fibre and you have, basically, the simplest possible fibre link. Speaking of fibre, while you can certainly use glass fibre (in the proper jacket) to connect these modules together, we recommend PMMA plastic fibre! It’s cheap, it’s not at all fragile, and you can cut it with scissors. In our experience, it requires no polishing at all, simply cut it with scissors and jam it into the connector.
The emitter and detector are soldered but not screwed into place. For field applications we recommend anchoring the connectors with a screw and nut. A 4-40 screw with nut works great but we don't carry the ideal 3/8" length. Alternatively we do carry a 3/8" screw and nut in the smaller 2-56 thread.
We've tested these modules at baud rates up to 1Mbps and distances up to 50 meters with no transmission errors.
