DESCRIPTION��
TheFirecommsDCto5MBdRedLink®transmitteris
based on the highly reliable Firecomms designed
Resonant Cavity Light Emitting Diode (RCLED)
technology.
It is housed in a non‐conducting plastic RedLink®
connector.The5MBdtransmitterisgreyincolour.
ThehousingsarecompatiblewiththeVersatileLink
style fiber plug and are optimized for use with
PlasticOpticFiber(POF)andPlasticCladSilica(PCS)
fiber.
Thetransmitter can be driven from TTLtypelogic
drivers.Itoperatesovertheindustrialtemperature
range of ‐40⁰C to +85⁰C, supporting many
industrialapplicationswherereliablecommandand
control response is required in electrically harsh
environments.
Thetransmitterusesalarge‐currentaperture(150
μmdiameter)red (650nm)eye‐safe RCLEDbased
on InGaP/InGaAlP/GaAs technology. It operates
over a wide range of drive current that can be
adjustedusingaserialresistortominimizecurrent
