I-100G QSFP28 LR4 optical module ivame ukusetshenziswa kanye ne-LC duplex single-mode fiber, futhi ibanga lokudlulisela lingafinyelela ku-10km.

I-100G QSFP28 PSM4 optical module ivame ukusetshenziswa kanye ne-MTP single-mode fiber, futhi ibanga lokudlulisela lingafinyelela ku-500m.

I-100G QSFP28 CWDM4 optical module ivame ukusetshenziswa kanye ne-LC duplex single-mode fiber, futhi ibanga lokudlulisela lingafinyelela ku-2km.

3. Isakhiwo sezintambo ezihlukene

Isakhiwo se-wiring se-100G QSFP28 SR4 optical module kanye ne-100G QSFP28 PSM4 optical module ziyafana, futhi zombili zidinga isakhiwo sezintambo eziningi ezisekelwe ku-interface ye-12-way MMF MTP.Umehluko wukuthi i-module ye-100G QSFP28 PSM4 optical kumele isebenze ku-fiber yemodi eyodwa I-100G QSFP28 SR4 optical module iku-multi-mode fiber.

Futhi amamojula we-100G QSFP28 LR4 optical kanye ne-100G QSFP28 CWDM4 optical modules ngokuvamile asetshenziswa kanye ne-LC duplex single-mode fibre patch cords, kusetshenziswa i-dual-pass dual-fiber-fiber structure SMF.

4. Umgomo wokusebenza uhlukile

Umgomo wokusebenza we-100G QSFP28 SR4 optical module kanye ne-100G QSFP28 PSM4 optical module iyafana ngokuyisisekelo.Lapho uthumela amasignali ekugcineni kokudlulisela, amasignali kagesi aguqulwa abe amasignali optical yi-laser array, bese edluliselwa ngokuhambisana ku-optical fiber.Lapho ifinyelela ekugcineni kokwamukela, I-photodetector array iguqula amasignali okubonayo ahambisanayo abe amasignali kagesi ahambisanayo, ngaphandle kokuthi eyokuqala iku-multi-mode fibre futhi eyakamuva iku-fiber yemodi eyodwa.

Umgomo wokusebenza we-100G QSFP28 LR4 optical module kanye ne-100G QSFP28 CWDM4 optical module ziyafana.Bobabili baguqula amasiginali kagesi we-4 25Gbps abe amasiginali we-4 LAN WDM optical, bese bewaphindaphinda abe isiteshi esisodwa ukuze kuzuzwe ukudluliswa kwe-100G optical.Ekupheleni kokwamukela, imojula i-demultiplexes 100G optical input ibe amasiginali we-4 LAN WDM optical, bese iwaguqulela eziteshini ezi-4 zokukhipha isignali kagesi.

Ukukhethwa kwesicelo se-100G QSFP28 module optical

Ngaphansi kwenethiwekhi ye-100G, indlela yokukhetha imodyuli ye-optical ye-100G QSFP28 efanelekile ingacatshangelwa kusukela kulezi zici ezintathu ezilandelayo:

1. I-Multimode fibre optic cabling phakathi kokushintsha: 5-100m

I-Optical 100G QSFP28 SR4 module optical, esebenzisa i-MTP interface (8 cores), ibanga lokudlulisela lapho lisetshenziswa ne-OM3 multimode fiber liyi-70m, futhi uma lisetshenziswa nge-OM4 multimode fiber, ibanga lokudlulisela liyi-100m, lilungele ukudluliselwa kwebanga elifushane ( ibanga lingaphansi kwamamitha ayi-100) kunethiwekhi ye-100G.

2. Izintambo zefayibha zemodi eyodwa phakathi kokushintsha: >100m-2km

Ungakhetha i-100G QSFP28 PSM4 optical module noma i-100G QSFP28 CWDM4 optical module, zombili ezifanele amanethiwekhi we-100G webanga eliphakathi nelifushane.I-100G QSFP28 PSM4 optical module isebenzisa i-8 parallel single-mode optical fibers ndawonye, ​​futhi ibanga lokudlulisela limayelana namamitha angu-500;i-100G QSFP28 CWDM4 optical module isetshenziswa kanye ne-single-mode optical fiber, futhi ibanga lokudlulisela lingafinyelela ku-2 km.

3. Ifayibha yemodi eyodwa yemodi ende: ≤10km

 ingakhetha i-100G QSFP28 LR4 module optical, ithatha isikhombimsebenzisi se-duplex LC, ibanga lokudlulisela lingafinyelela ku-10km uma lisetshenziswe nge-fiber yemodi eyodwa, ifanele inethiwekhi yebanga elide le-100G (ibanga elingaphezu kwamakhilomitha angu-2 nangaphansi kwamakhilomitha angu-10).

I-HUANET inganikeza wonke lawa mamojula we-100G QSFP28 optical ngentengo yokuncintisana, wamukelekile ukusithumelela uphenyo.
