3. Ulwakhiwo lwee-wiring ezahlukeneyo

Isakhiwo se-wiring ye-100G QSFP28 SR4 imodyuli ye-optical kunye ne-100G QSFP28 PSM4 imodyuli ye-optical iyafana, kwaye zombini ifuna i-multi-fiber wiring structure esekelwe kwi-interface ye-12 ye-MMF MTP.Umahluko kukuba imodyuli ye-100G QSFP28 ye-PSM4 ye-optical kufuneka isebenze kwi-fiber ye-mode eyodwa I-module ye-100G QSFP28 SR4 ye-optical module i-multi-mode fiber.

Kwaye i-100G QSFP28 LR4 iimodyuli ze-optical kunye ne-100G QSFP28 CWDM4 iimodyuli ze-optical zivame ukusetyenziswa kunye ne-LC duplex i-fiber patch cords single-mode, usebenzisa i-dual-pass dual-fiber-fiber structure SMF.

4. Umgaqo wokusebenza wahlukile

Umgaqo osebenzayo we-100G QSFP28 SR4 imodyuli ye-optical kunye ne-100G QSFP28 PSM4 imodyuli ebonakalayo iyafana.Xa uhambisa izibonakaliso ekupheleni kokudlulisa, iimpawu zombane ziguqulwa zibe yimiqondiso ye-optical nge-laser array, kwaye emva koko idluliselwe kwi-parallel kwi-fiber optical.Xa ufikelela ekupheleni kokufumana, I-photodetector array iguqula izibonakaliso ze-optical parallel kwi-parallel optical signals, ngaphandle kokuba yangaphambili ikwi-multi-mode fiber kunye neyokugqibela kwi-fiber mode eyodwa.

Umgaqo wokusebenza we-100G QSFP28 LR4 imodyuli ye-optical kunye ne-100G QSFP28 CWDM4 imodyuli ye-optical iyafana.Bobabini baguqula izibonakaliso zombane ze-4 25Gbps kwiimpawu ze-4 ze-LAN WDM ze-optical, kwaye emva koko ziphindaphinda zibe ngumjelo omnye ukufezekisa ukuhanjiswa kwe-optical 100G.Ekupheleni kokufumana, imodyuli i-demultiplexes i-100G i-optical input kwi-4 ye-LAN WDM ye-optical signals, ize iguqule ibe yi-4 iziteshi zombane zombane.

Ukukhethwa kwesicelo se-100G QSFP28 imodyuli ye-optical

Ngaphantsi kwenethiwekhi ye-100G, indlela yokukhetha imodyuli ye-optical ye-100G QSFP28 efanelekileyo inokuqwalaselwa kule miba mithathu ilandelayo:

1. I-Multimode fiber optic cabling phakathi kokutshintsha: 5-100m

I-Optional 100G QSFP28 SR4 imodyuli ye-optical, esebenzisa i-MTP interface (i-8 cores), umgama wokuhambisa xa usetyenziswa nge-OM3 i-fiber multimode yi-70m, kwaye xa isetyenziswe kunye ne-OM4 i-fiber multimode, umgama wokuhanjiswa ngu-100m, ulungele ukuhanjiswa kwexesha elifutshane (I. umgama ungaphantsi kweemitha ezili-100) kwinethiwekhi ye-100G.

2. I-fiber yendlela enye yocingo phakathi kokutshintsha:> 100m-2km

Unokukhetha i-modyuli ye-100G QSFP28 ye-PSM4 ye-optical okanye i-100G QSFP28 CWDM4 imodyuli ye-optical, zombini ezo zifanelekileyo kumgama ophakathi kunye omfutshane we-100G amanethiwekhi.I-100G QSFP28 PSM4 imodyuli ye-optical isebenzisa i-8 parallel single-mode optical fibers kunye, kwaye umgama wokuhambisa umalunga neemitha ze-500;i-100G QSFP28 CWDM4 imodyuli ye-optical isetyenziswe kunye ne-fiber optical mode enye, kwaye umgama wokuhambisa unokufikelela kwi-2 km.

3. I-fiber yendlela ende yendlela enye: ≤10km

 ingakhetha i-100G QSFP28 LR4 imodyuli ye-optical, ithatha i-duplex LC interface, umgama wokudlulisa unokufikelela kwi-10km xa isetyenziswe ngefiber ye-single-mode, ifanelekile kumgama omde we-100G inethiwekhi (umgama ongaphezu kweekhilomitha ze-2 kunye neekhilomitha ezingaphantsi kwe-10).

I-HUANET inokubonelela zonke ezi 100G QSFP28 iimodyuli ze-optical kunye nexabiso elikhuphisanayo, wamkelekile ukuba usithumele umbuzo.
