of continuous digital data. The RCLED
is
encapsulated in a lensed clear molded plastic
packageforoptimumcouplingtoPlasticOpticFiber
(POF). It operates over the industrial temperature
rangeof‐40⁰Cto+85⁰C.
The 10 MBd transmitter produces higher optical
power for the same input current relative to the
standard Firecomms 10 MBd
device (FT10MHNR).
This allows a lower overall current consumption
whenusedinanexistinglinkdesign.
The transmitter is assembled in a gray non

simplifieslinksetup
