Transceiver txhais: Dab tsi yog nkag mus rau hauv tej no

 

Yog li kho qhov kev hloov kho kho qhov muag. Lawv nyob hauv cov thawv uas ua rau muaj fiber ntau optic networks ua haujlwm -} hloov cov cim hluav taws xob rau hauv lub teeb thiab rov qab dua. Lub transmitter sab tua tawm lub teeb pulses los ntawm fiber ntau, cov neeg tau txais sab ntes lawv thiab hloov lawv rov qab rau hauv cov ntaub ntawv hluav taws xob koj cov cuab yeej siv tau.

Koj yuav pom cov ntaub ntawv hauv cov ntaub ntawv, kev soj ntsuam TV, zoo nkauj npaum li cas txhua qhov chaw ntawm cov ntaub ntawv txav mus los. Cisco qhia lawv 400g transceivers ntim ntau lawm nyob rau hauv 2019, uas muab rau koj cov khoom siv sai sai li cas los ntawm 10G ua lej rau 400g nyob rau hauv zoo li kaum tsib xyoos.

 

 

Yuav ua li cas tsim lag luam - Offs ua haujlwm

 

Engineers pheej sib ntaus sib luag ntawm no. Cov ntawv me me suab zoo heev kom txog thaum koj paub tias koj muaj lub hwj chim ntau dua rau hauv qhov chaw tsawg dua, uas txhais tau tias muaj teeb meem cua sov. Lub QSFP28 Daim Ntawv Factor tau thawb 100 Gbps los ntawm ib tus qauv txog qhov loj me ntawm koj tus ntiv tes xoo- Yog tias koj ua lej.

Kub muaj ntau dua li cov neeg xav. Cov neeg tau txais kev pab -} Cov khoom qib qib ua haujlwm tej zaum 0 txog 70 degree. Kev siv tub rog thiab tub rog xav tau-} {+85℃lossis siab dua, qee zaum sib luag. Tias yog vim li cas cov tuam txhab zoo li radiall tsom rau cov qauv tsim tawm - lub teeb thiab cov tsev neeg txuas ntxiv thaum ua kom cov neeg siv fais fab.

Kev cuam tshuam hluav taws xob hluav taws xob hloov kho tau

Iav fiber tsis quav ntsej txog EMI. Muab tooj liab nyob ib sab ntawm lub cev muaj zog lossis xov tooj cua xa tawm thiab koj yuav tau nrov. Fiber ntau ... tsis yog. Uas yog vim li cas submarines, dav hlau, muaj nroj tsuag txhua yam nyiam fiber ntau rau kev txuas tseem ceeb. Koj tuaj yeem khiav Fiber txoj cai nrog kev ua siab zoo li - voltage kab tsis muaj teeb meem.

 

Cov lej tiag tiag los ntawm daim teb

 

Juniper tes hauj lwm luam tawm cov ntaub ntawv luam tawm lawv txoj kev txhim kho kho qhov muag ua tiav 14.4 TBPS muaj peev xwm dhau ntawm kev sib txuas ib leeg ntawm 2023 siv wavelength divisen multiplexing. Qhov ntawd tsis yog theoretical - uas tau tso tawm hauv cov tuam txhab tsheb thauj khoom.

Lub d - pa series radiall ua tau nce mus txog 120 gbps thiab dhau mus rau ib qho kev thauj mus los ntawm ib transceiver tawm ntawm 100g. Nto mount thiab cov kev xaiv sib cav cia koj tawm tsam ncaj qha rau cov laug cam lossis kub} swap modules nyob ntawm seb koj cov ntawv thov xav tau li cas.

Kev noj fais fab sib txawv wildly. Lub 10g SFP + tej zaum yuav rub 1.5 WALTS. Ib qho 400g transceer yuav rub 12 {- 15 watts. Muab ntau uas nyob thoob plaws ntau pua cov chaw nres nkoj hauv ib qho hloov thiab tam sim no koj cov chaw txias tawg, yuav luag txhua lub sijhawm ua ke qee zaum.

 

 

Daim Ntawv Qhia Txog Cov Qauv thiab MSA

 

Ntau -} Qhov pom zoo cov lus pom zoo li koj tsis tau kaw rau ib tus neeg muag khoom. SFP, SFP +, QSFP, QSFP28, QSFP - DD ... cov acronyms nce. Txhua tiam feem ntau txhawb nqa ntau dua kev ceev lossis ntau txoj kab khiav. Qsfp - dl noj ob npaug ntawm 4 txog 8, uas yog li cas los ntawm 400g modules yam tsis muaj tag nrho cov nyiaj rov qab txhua yam.

Cov pob khoom ua haujlwm tseem muaj nyob rau cov ntawv thov tshwj xeeb. Tub rog, aerospace, harsh kev muaj chaw muaj txuj ci {}} Cov kev hloov pauv no uas muaj sia nyob ua ke, xyuam xim, hluav taws xob tsuag, hluav taws xob. Tus Qauv Kev Lag Luam Kev Lag Luam Kev Lag Luam Kev Lag Luam Tsis Txaus Siab Tsis Muaj Cov Lus Cog Tseg.

Channel sib koom ua ntom ntom ntom

Cramming Ntau cov qhab nia rau hauv tib txoj kev taug kev yuav tsum muaj kev tswj hwm thermal zoo dua thiab kev sib cav sib ceg. Lub wavelength ruaj khov ntawm DWDM Transceiver yuav tsum nyob hauv ib yam dab tsi xws li 0.01 nm lossis koj tau txais crosstalk ntawm cov kab. Tias yog vim li cas cov no nqi dab tsi uas lawv raug nqi - qhov precision uas yuav tsum muaj yog nyuaj.

Radiall txoj kev mus nrog cov channel sib txawv suav (2, 4) cia rau koj phim tus mob transceer rau koj txoj kev xav tau es tsis txhob them rau cov peev xwm uas koj yuav tsis siv. Lub ntsuas hluav taws xob xaus rau kev khiav ntawm cov nrawm dua tsis xav tau 12 {{} Cov tsiaj nyaum beast {

 

 

Qhov kev siv tshuab no tau siv qhov twg

 

Telecom Backbley tes tes hauj lwm txuas cov nroog thiab cov teb chaws {{}}} powered ntev- kev hloov pauv hloov pauv sab nraud nrog kev ua kom sov. Huawei tus Optixtrans Series txog 800 km yam tsis muaj kev hloov kho uas siv cov kev kuaj pom thiab kev ua yuam kev mus rau sab nraud.

Cov ntaub ntawv nruab nrab kev sib txuas ua ke ntawm cov tuam tsev lossis cov chaw pw hav zoov ib txwm khiav 10g lossis 25g toj ib kab mus rau qhov luv luv, tej zaum 2 -}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} 10 km. Txoj kev hloov pauv nqi tsawg dua vim tias koj tsis tas yuav tau txais txoj kev zoo nkauj ntev ntev thiab cov kev txhim kho hnyav.

Sab hauv cov ntaub ntawv Center Center sib txuas txuas cov servers hloov chaw, koj tab tom saib tau luv heev - 100 meters lossis tsawg dua qee zaum. Cov kev hloov pauv hloov mus rau tus nqi qis thiab lub zog qis es tsis txhob nrug deb.

Compatibility nrog FPGAS thiab Serdes Interfaces teeb meem rau kev ua kom tiav cov ntawv thov. Koj xav tau hluav taws xob hluav taws xob ntawm lub transceiver kom phim rau qhov kev xav tau, tsis yog koj ntxiv cov kev hloov pauv theem uas noj lub hwj chim thiab ntxiv cov latency.

Qhov tsis - hlau siv txhais tau tias koj tuaj yeem rub cov chaw nyob ntawm qhov chaw tooj liab yuav tuaj yeem teeb meem hauv av. Cov cuab yeej siv khomob kho mob, cov cuab yeej scient, suab / yees duab- ntau qhov chaw uas muaj teeb meem huv si teeb meem.
