Transmitter diode
The FDE2850 series fibre optic transmitter (Tx) diode from OMC is optimised for use with 200µm glass fibre optic systems and delivers high power at fast speeds for demanding applications, such as those found in mass transport, petrochemical, industrial datacomms and high-voltage energy infrastructure applications.

The emitter is available as a housed fibre-optic transmitter module in a range of housing and connector styles. Popular housed variants include the H13AE2850IR - a PCB-mount version with ST connector - and the H22E2850IR, which is the SMA PCB-mounting variant; both feature a precision-machined, all metal body and a rugged screw-mount design for reliable mechanical connection to circuit boards. The device delivers a typical coupled power of 813µW at 100mA into 200µm glass optical fibre, and can also be aligned to deliver good levels of power into fibre sizes as small as 50µm. Operating at the infrared 850nm wavelength, the device features a very fast rise and fall time of just 12ns. Whereas typical manufacturing lead times for industrial f/o transmitters can often exceed 16 weeks, OMC say it can turn around transmitter batches based on the FDE2850 in closer to 6-8 weeks, and that this can be further expedited in many cases.
