Kev sib txuas lus kho qhov muag | PON Daim Ntawv Thov Technology Taw Qhia (2)
Kev taw qhia txog ntau yam PON systems 1. APON thev naus laus zis Nyob rau nruab nrab xyoo 1990, qee tus neeg ua haujlwm loj hauv network tau tsim lub Full Service Access Network Alliance (FSAN), uas nws lub hom phiaj yog los tsim cov qauv kev sib koom ua ke rau cov khoom siv PON kom cov khoom lag luam thiab cov neeg ua haujlwm tuaj yeem nkag mus rau hauv cov khoom siv PON. PON eq...Nyeem ntxiv - los ntawm Admin / 26 Nov 19 /0Cov lus pom
Kev sib txuas lus kho qhov muag | PON Technology Yuav Ua Li Cas Txhim Kho Network Saib Xyuas Kev Xa Mus Los Ntawm Cov Khaub Ncaws?
Nrog rau txoj kev loj hlob ntawm cov nroog niaj hnub mus rau ntau qhov kev ua haujlwm, kev tsim hauv nroog tau dhau los ua ntau thiab nyuaj, thiab muaj ntau pua, pua pua, lossis ntau txhiab lub ntsiab lus hauv av. Txhawm rau kom ntseeg tau tias cov haujlwm ua haujlwm tuaj yeem tuav lub sijhawm tiag tiag, pom meej thiab ua tau zoo video duab ...Nyeem ntxiv - los ntawm Admin / 22 Nov 19 /0Cov lus pom
Kev sib txuas lus kho qhov muag | Lub tshuab tseem ceeb ntawm 100G Ethernet, koj puas tau txais nws?
Lead: 100G Ethernet los ntawm kev tshawb fawb mus rau kev lag luam, yuav tsum tau daws cov thev naus laus zis tseem ceeb ntawm kev sib txuas, ntim, kev sib kis, cov khoom tseem ceeb, thiab lwm yam. Cov thev naus laus zis tseem ceeb ntawm 100G Ethernet tam sim no cuam tshuam nrog lub cev txheej, channel convergence technology, multi-fiber channel thiab yoj.

Taw qhia rau PON Technology
1.Basic qauv ntawm PON PON (Passive Optical Network) PON yog ib leeg-fiber bidirectional optical access network siv ib tug point-to-multipoint (P2MP) qauv. Lub PON system yog tsim los ntawm cov kab hluav taws xob kho qhov muag (OLT), qhov muag pom kev sib txuas (ODN), thiab chav tsev kho qhov muag (ONU) ntawm ...Nyeem ntxiv - los ntawm Admin / 16 Nov 19 /0Cov lus pom
Basic tswvyim ntawm optical module
1.Laser qeb Ib lub laser yog qhov tseem ceeb tshaj plaws ntawm cov khoom siv kho qhov muag uas txhaj tam sim no rau hauv cov khoom siv semiconductor thiab emits laser teeb los ntawm photon oscillations thiab nce hauv kab noj hniav. Tam sim no, feem ntau siv lasers yog FP thiab DFB lasers. Qhov txawv yog qhov sem ...Nyeem ntxiv - los ntawm Admin / 14 Nov 19 /0Cov lus pom
Lub tswv yim yooj yim, muaj pes tsawg leeg thiab cov yam ntxwv ntawm kev sib txuas lus fiber ntau optical
Basic tswvyim ntawm optical fiber kev sib txuas lus. Ib qho khoom siv kho qhov muag yog ib qho dielectric optical waveguide, lub qauv waveguide uas thaiv lub teeb thiab nthuav tawm lub teeb nyob rau hauv axial kev taw qhia.
