Kev taw qhia txog cov100GPSM4 tus qauv yog tsuas yog txo tus nqi ntawm cov khoom siv kho qhov muag rau cov ntawv siv 100GBASE-LR4 kim. 100G PSM4 optical modules yog ib hom kev sib txuas plaub-channel optical modules, uas yog tsim nyog rau 500-meter daim ntawv thov. 100G CWDM4 tus qauv yog tsim los rau kev xa tawm ntawm 2km 100G txuas hauv cov ntaub ntawv chaw. Qhov kev sib txuas ntawm 100G CWDM4 optical module ua raws li ob hom tib hom 2km 100G optical interface specification, thiab kis tau tus mob mus txog 2km.
100G tau teev vim tias nws tau siv ntau dua hauv cov ntaub ntawv chaw sib cuam tshuam. Kuj tseem muaj hom optical module, uas kuj tseem kub tsis ntev los no. Qhov ntawd yog 5G fronthaul optical module. Ib qho tseem ceeb tshaj plaws yog 25G Bidi ib leeg-fiber bidirectional optical module. Cia peb qhia cov kev daws teeb meem hauv kev nthuav dav. Ib qho kev nrhiav tau lub teeb-emitting module Ib qho kev nrhiav tau lub teeb-emitting module txais TOSA lossis ROSA cov khoom kom paub txog kev xa lossis tau txais kev ua haujlwm. Xws li optical modules tsuas muaj kev ua haujlwm ntawm kev txais lossis xa tawm.
Optical Transceiver
Kev sib xyaw ua ke ntawm optical transceiver module yog tsim los ntawm cov khoom siv optoelectronic, kev ua haujlwm circuits thiab optical interfaces. Cov khoom siv optoelectronic suav nrog ob ntu: kis thiab txais. Kev sib xyaw ua ke ntawm optical transceiver module yog cov cuab yeej tseem ceeb ntawm kev sib txuas lus kho qhov muag, uas ua tiav qhov kev hloov kho qhov muag-hluav taws xob / hluav taws xob-kho qhov muag hloov pauv ntawm cov teeb liab kho qhov muag. Nws muaj ob ntu: qhov tau txais thiab qhov xa tawm. Qhov tau txais ib feem paub txog kev hloov dua siab tshiab-hluav taws xob, thiab qhov kev xa tawm paub txog kev hloov pauv hluav taws xob-optic. Kev xa tawm ib feem: Cov khoom siv hluav taws xob hluav taws xob nrog qee tus lej code yog ua tiav los ntawm cov tsav tsheb sab hauv los tsav lub semiconductor laser (LD) lossis lub teeb emitting diode (LED) kom emit ib qho kev hloov kho qhov muag teeb liab ntawm tus nqi sib xws, nrog lub hwj chim kho qhov muag tsis siv neeg. tswj Circuit Court (APC) sab hauv. , kom cov zis optical teeb liab zog ruaj khov. Tau txais ib feem: Cov teeb liab kho qhov muag ntawm qee tus lej code yog nkag mus rau hauv lub module thiab hloov mus rau hauv lub teeb liab hluav taws xob los ntawm photodetection diode, thiab cov teeb liab hluav taws xob ntawm tus lej code tus nqi yog tso tawm tom qab lub preamplifier, thiab cov teeb liab tso zis feem ntau yog PECL qib. . Nyob rau tib lub sijhawm, thaum lub zog input optical tsawg dua ib qho nqi, lub tswb ceeb toom yuav raug tso tawm.

Dab tsi yog dual fiber ntau bidirectional optical module? Peb cov pa transceiver integrated module yog dual-fiber bidirectional optical module, uas yog, muaj ob lub optical fiber jacks kom ua tiav ib txhij kis tau tus mob ntawm optical signals nyob rau hauv ob qho tib si cov lus qhia, uas yog, lub optical module muaj ob ports, TX yog lub transmitting chaw nres nkoj, RX yog qhov chaw nres nkoj txais. ; Optical fiber kis tau tus mob yog ib leeg-fiber unidirectional, yog li ob lub optical fibers yuav tsum tau ua kom tiav kev sib txuas lus bidirectional.
Dab tsi yog ib qho fiber ntau bidirectional optical module? BiDi optical modules yog compact nyob rau hauv cov qauv thiab yog tsuas yog siv nyob rau hauv lub tshav pob ntawm optical kev sib txuas lus, nrog rau kev sib txuas lus thiab bidirectional cov ntaub ntawv kev sib txuas lus. Ib leeg-fiber bidirectional los yog BiDi, hais txog ib txhij kis tau tus mob thiab txais tos ntawm optical signals nyob rau hauv ob txoj kev nyob rau hauv ib tug optical fiber, ib yam li cov pem hauv ntej thiab nram qab txoj kab sib cais los ntawm kev sib cais txoj siv nyob rau hauv txoj kev, thiab cov tsheb ntawm ob sab yog nyob rau hauv lawv tus kheej. txoj kab. Tsav tsheb tsis cuam tshuam nrog ib leeg.
