Kev sib txuas lus nrog lub teeb yoj raws li lub teeb liab thiab Optical fiber ntau li qhov nruab nrab kis tau tus mob hu ua Optical fiber kev sib txuas lus system. Qhov zoo ntawm kev sib txuas lus fiber ntau piv nrog kev sib txuas lus cable thiab kev sib txuas lus wireless yog: muaj peev xwm sib txuas lus loj, tsis tshua muaj kev sib txuas lus, muaj zog tiv thaiv hluav taws xob cuam tshuam, muaj zog tsis pub lwm tus paub, thiab cov khoom siv raw ntawm fiber ntau kis nruab nrab yog silicon dioxide nrog ntau cia. Tsis tas li ntawd, fiber ntau optical muaj qhov zoo ntawm qhov me me, lub teeb yuag thiab tus nqi qis piv nrog cable.
Daim duab hauv qab no qhia txog cov khoom ntawm ib qho yooj yim photonic integrated circuit:laser, optical reuse thiab demultiplexing ntaus ntawv,photodetectorthiabmodulator.

Lub hauv paus qauv ntawm optical fiber bidirectional kev sib txuas lus system muaj xws li: hluav taws xob transmitter, optical transmitter, kis fiber ntau, optical receiver thiab hluav taws xob receiver.
Kev kub ceev hluav taws xob teeb liab yog encoded los ntawm lub tshuab hluav taws xob xa mus rau qhov muag pom, hloov mus rau cov teeb liab kho qhov muag los ntawm cov khoom siv hluav taws xob xws li Laser ntaus ntawv (LD), thiab tom qab ntawd txuas mus rau cov khoom siv fiber ntau.
Tom qab qhov kev ncua deb ntawm cov teeb liab kho qhov muag los ntawm ib hom fiber ntau, erbium-doped fiber ntau amplifier tuaj yeem siv los ua kom cov teeb liab kho qhov muag thiab txuas ntxiv mus. Tom qab qhov kev txais kho qhov muag kawg, cov teeb liab kho qhov muag tau hloov mus rau hauv cov teeb liab hluav taws xob los ntawm PD thiab lwm yam khoom siv, thiab cov teeb liab tau txais los ntawm cov hluav taws xob txais los ntawm kev ua hluav taws xob tom ntej. Cov txheej txheem ntawm kev xa thiab txais cov teeb liab nyob rau hauv qhov kev taw qhia tsis sib xws yog tib yam.
Txhawm rau kom ua tiav cov txheej txheem ntawm cov khoom siv hauv qhov txuas, lub optical transmitter thiab optical receiver nyob rau tib qhov chaw yog maj mam muab tso rau hauv ib qho optical Transceiver.
Lub siab ceevOptical transceiver moduleyog tsim los ntawm Receiver Optical Subassembly (ROSA; Transmitter Optical Subassembly (TOSA)) sawv cev los ntawm cov khoom siv kho qhov muag, cov khoom siv tsis zoo, cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob sib txuas tau ntim. optical chips.

Nyob rau hauv lub ntsej muag ntawm lub cev lub cev tsis muaj zog thiab cov kev cov nyom uas tau ntsib hauv kev txhim kho microelectronics thev naus laus zis, tib neeg tau pib siv photons los ua cov ntaub ntawv xa mus kom ua tiav bandwidth ntau dua, kev nrawm dua, kev siv hluav taws xob tsawg, thiab txo qis photonic inteated circuit (PIC). Lub hom phiaj tseem ceeb ntawm photonic integrated voj yog kom paub txog kev sib koom ua ke ntawm kev ua haujlwm ntawm lub teeb tiam, kev sib txuas, kev hloov pauv, lim dej, kev sib kis, kev tshawb nrhiav thiab lwm yam. Thawj tsav tsheb ntawm photonic integrated circuits los ntawm cov ntaub ntawv kev sib txuas lus, thiab tom qab ntawd nws tau zoo heev tsim nyob rau hauv microwave photonics, quantum ntaub ntawv ua, nonlinear optics, sensors, lidar thiab lwm yam teb.
