DESCRIPTION)
The! Firecomms! DC!to!10! MBd! low! current!
RedLink®! transmitter! is! a! highly! reliable! Resonant!
Cavity!Light!Emitting!Diode!(RCLED)!which!operates!
as! a! visible! optical! source! generating! red! 650! nm!
light! at! data! rates! from! burst ! mod e ! DC! to! a!
maximum! of! 10! MBd! of! continuous! digital! data.!
The! RCLED! is! encapsulated! in! a! lensed! clear!
molded! plastic! package! for! optimum! coupling! to!
Plastic! Optic! Fiber! (POF).! It! operates! over! the!
industria l!te mperature!ra n ge !o f!-40!���C !to!+85!⁰C.!
!
The! 10! MBd! transmitter! produces! higher! optical!
power! for! the! same! input! current! relative! to! the!
standard! Firecomm s! 10! MBd ! d evice! (FT 10M HN R).!
This! allows! a! lower! overall! current! consumption!
