Kenyelletso ea mantlha ea optical module
Optical module e entsoe ka lisebelisoa tsa optoelectronic, li-circuits tse sebetsang le li-interfaces tsa optical. Lisebelisoa tsa optoelectronic li kenyelletsa likarolo tse peli: ho fetisa le ho amohela. Ka bokhutšoanyane, mosebetsi oa mochine oa optical ke ho fetolela letšoao la motlakase ho letšoao la optical qetellong ea ho romela. Ka mor'a hore letšoao la optical le fetisetsoe ka fiber ea optical, qetello e amohelang e fetola letšoao la optical ka letšoao la motlakase.
Karolo ea phetisetso ke: lets'oao la motlakase le kenang ka sekhahla se itseng se sebetsoa ke chip ea koloi e ka hare, ebe e khanna laser ea semiconductor (LD) kapa diode e khanyang (LED) ho ntša lets'oao la optical le fetotsoeng la sekhahla se lumellanang. Potoloho ea ka hare ea optical power othomathike ea ho laola e hlomelloa ho boloka matla a optical signal a tsitsitseng a tsitsitse.
Karolo e amohelang ke: mochini o kenang oa optical signal o nang le sekhahla se itseng o fetoloa hore e be lets'oao la motlakase ka diode ea optical discovery, 'me lets'oao la motlakase le nang le sekhahla se tsamaisanang le lona le hlahisoa ka mor'a preamplifier.
-Mohopolo oa motheo oa optical module-
Port-optical module ke lebitso le akaretsang la mekhahlelo e fapaneng ea module, ka kakaretso e bua ka optical transceiver integrated module.
- Mosebetsi oa optical module-
Mosebetsi oa eona ke feela ho hlokomela phetoho lipakeng tsa matšoao a optical le matšoao a motlakase.
- Sebopeho sa module oa Optical-
Hangata mochine oa optical o entsoe ka transmitter optical, optical receiver, functional circuit le optical (motlakase) interface.
Ho transmitter, chip ea mokhanni e sebelisa lets'oao la motlakase la mantlha, ebe e khanna semiconductor laser (LD) kapa light emitting diode (LED) ho ntša lets'oao la optical le fetotsoeng.
Boema-kepe bo pheletsong ea ho amohela. Kamora hore lets'oao la optical le kene, le fetoloa lets'oao la motlakase ka diode ea ho bona, ebe e ntša lets'oao la motlakase ka preamplifier.
