Plastic fibre links use simple and inexpensive LEDs and photodiodes as transmitters and receivers, respectively. The most common type of plastic optical fibre is composed of a polymethylmethacrylate (PMMA) core encased in fluoride-based carbon polymer.
Infineon Technologies offers plastic fibre-optic transmitter diodes and photodetector receivers that have the following features: wavelengths: 650, 660 and 950 nm; data rate DC up to 5 Mbps; operating temperature ranges -40 to +85°C; 2,2 mm aperture holds standard 1000 µm plastic fibre; no fibre stripping required; good linearity; and moulded microlens for efficient coupling.
The active photodetector receivers operate on 5 to 15 V supply. They feature -40 to +85°C operating temperature range, transfer rate: (5 Mbps and low switching threshold. The bipolar IC delivers open-collector output (TTL-compatible). The receivers are sensitive in visible and near IR range.
The plastic connector housing has a mounting screw attached to the connector. The light-tight housing allows interference-free transmission. Transmitter and receiver can be flexibly positioned. No crosstalk. Auto insertable and wave solderable. Supplied in tubes.
