심플렉스 광섬유 링크 송수신 모듈
(Fiber Simplex Breakout)
개요
- 본 제품은 심플렉스 광섬유 링크 송수신 모듈입니다.
- 한쌍의 보드로 광섬유를 UART에 연결하는 것이 아닌 LED나 포토 검출기에 단순히 직접 연결하고자 하는 경우를 위해 디자인되었습니다.
- 보드를 띄어 내서 광섬유를 한가닥 연결하여 링크를 만들수 있습니다.
- 각 보드에는 VCC, Gnd, Signal, Invertered Signal의 4개의 핀이 있습니다.
특징
- Easily create fiber serial links between embedded devices
- Supports Serial Baud Rates up to 1Mbps
- 5V and 3.3V compatible

This board is actually a pair of boards! We wanted to design a product that gave you the bare minimum amount of support circuitry for playing with these modules from Industrial Fiber Optics. This product is for people who might not be connecting their fiber modules directly to a UART, and instead want to interface with them simply as an LED and a photodetector. Using a pair of pliers, the two sides of the Fiber Simplex Breakout can be snapped apart along the perforated line to create a one-way fiber link. Both the receiver and transmitter have four pins: VCC, Ground, Signal, and Inverted Signal. See the Hookup Guide for information about each signal.
The Industrial Fiber Optics line of emitters and detectors are by far the most economical way we've found to create a simple fiber 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 fiber 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 fiber and you have, basically, the simplest possible fiber link. Speaking of fiber, while you can certainly use glass fiber (in the proper jacket) to connect these modules together, we recommend PMMA plastic fiber! 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.
We've tested these modules at baud rates up to 1Mbps and distances up to 50 meters with no transmission errors.
