400g LR4

400g QSFP-DD LR4 (400G LR4) kho qhov muag transceiver

Kev piav qhia dav dav

MCR -6 peccc -10} Yog ib qho kev sib txuas lus me me (QSFP-DD) Optical Transcials tsim Cov qauv hloov pauv 8 Raws li 50GB \/ S (PAM4) cov ntaub ntawv hluav taws xob rau 400 ntawm CWDM kho kho kho qhov muag thiab ntau yam channel rau 400gb \/ s kho qhov muag. Ntawm tus txais sab, tus qauv hloov kho kom zoo ntawm-multipxes

Ib qho 400GB \/ s kho qhov muag rau 4 channel ntawm CWDM kho qhov muag kos npe thiab hloov lawv mus rau 8GB \/ S (PAM4) cov khoom siv hluav taws xob. Qhov chaw yoj nruab nrab ntawm 4 CWDM channel yog 1271, 1291, 1311 thiab 1331 nm ua cov tswv cuab ntawm CWDM wavelength daim phiaj tau hais tseg hauv itu-t g.694.2. Tus tswv tsev fec yog yuav tsum tau txhawb mus rau 10km fiber ntau kis.

Q: 400G LR4 txawv li 400g dr4 modules?

A: Qhov tseem ceeb tshaj plaws yog qhov deb thiab tus nqi:

LR4: Rau 10 km + scararios (piv txwv li, hla kev sib txuas-chaw pw), qis zog (feem ntau tsawg dua lossis sib luag rau 10W).

DR4: Txwv rau 500m, haum rau hauv cov hlua sib txuas nkaus xwb.

Q: Dab tsi yog qhov tseem ceeb siv kev ceev faj?

A: Cov lus qhia tseem ceeb:

Kev tu fiber ntau: huv si LC txuas txhua hli nrog cov cuab yeej tshwj xeeb los tiv thaiv cov plua plav.

Tsis txhob ntse khoov: tswj fiber ntau khoov radius loj dua los yog sib npaug rau 30mm los tiv thaiv cov paib teeb liab.

Tswj kub: ua haujlwm tsis pub dhau 0 degree -70 degree; Ua kom muaj qhov cua txaus kom muaj cov pa hluav taws xob kub.

Q: Nws puas txhawb nws cov kev ceeb toom tsis ua haujlwm?

A: Yog! Cov kev soj ntsuam kev noj qab haus huv (DCM), hluav taws xob, hluav taws xob, thiab lwm yam

MacroChip tsom mus ua ib qho kev coj ua thoob ntiaj teb ntawm silicon photonics chips thiab transceivers,

Tsav cov evolution tom ntej ntawm high-kev ua haujlwm sib txuas daws thoob ntiaj teb.
