luv- kis tau tus mob nyob deb li ntawm 25G mus rau 50G ib wavelength

Ethernet luv- kis tau tus mob:
| Ethernet Standard | MMF | Parallel SMF | 2km swb | 10 km SMF | 40 km SMF |
|---|---|---|---|---|---|
| 25 G BASE- | SR | LR | ER | ||
| 40 G BASE- | SR4 | FR | LR4 | ER 4 | |
| 50 G BASE- | SR | FR | LR | ||
| 100 G BASE- | SR10 SR4 SR2 | PSM4 | CWDM4 CLR4 FR2 | DR 2 FR4 LR4 | ER 4 |
| 200 G BASE- | SR4 | DR 4 | FR4 | LR4 | |

Hais txog evolution ntawm technology roadmap, qhov ntxov tshaj plaws100G luv- kis tau tus mobevolved los ntawm 10 × 10 mus rau 4 × 25G, nrog rau txhua tus tib channel yog 25G NRZ, ua hauj lwm raws li lub hauv paus txheej txheem.
Los ntawm kev xaiv ib qho ntawm cov channel, peb tau txais ib qho - wavelength 25G kis tau tus mob.
Cov 4 channel tau ntxiv ntau ntxiv rau hauv 16 channel, ua rau 16 × 25=400G kis tau tus mob.
Ib leeg -wavelength 25G NRZ, sawv cev los ntawm cov dots grey hauv daim duab hauv qab no, yog lub ntsiab lus kub ntawm kev tshawb fawb hauv kev lag luam rau ob xyoos dhau los. Tsiv mus tom ntej, luv - kis tau tus mob yuav tsom mus rau cov dots dub, uas sawv cev ib zaug xwb - wavelength 50G PAM4 thev naus laus zis.
Cov thawv dashed hauv cov lus hauv qab no qhia txog ntau yam kev sib txuas rau ib leeg -wavelength 50G PAM4
Cov thawv dashed sawv cev rau cov thev naus laus zis uas yuav hloov zuj zus mus ntxiv thiab paub tab nyob rau ob xyoos tom ntej, thaum cov kauj ruam tom ntej tom qab ntawd yog ib qho - wavelength 100G PAM4 thev naus laus zis tau qhia hauv lub thawv khoom.
