Umehluko phakathi kwamamojula amane e-optical e-100G QSFP28

1. Izindlela ezahlukene zokudlulisela

Imojula ye-optical ye-100G QSFP28 SR4 kanye nemojula ye-optical ye-100G QSFP28 PSM4 zombili zamukela isikhombimsebenzisi se-MTP esineziteshi eziyi-12, futhi zenza ukudluliswa kwe-100G yeziteshi eziyi-8 optical fiber bidirectional ngesikhathi esisodwa.

I-100G QSFP28 LR4 optical module kanye ne-100G QSFP28 CWDM4 optical module zisebenzisa iziteshi ezine ezizimele zamaza obubanzi bokudlulisa i-100G, futhi zisebenzisa ubuchwepheshe bokuphindaphindwa kwamaza obubanzi bobubanzi bobubanzi bokudlulisa ukuze ziphindaphinde amasignali amane amaza obubanzi bobubanzi ku-fiber optical yemodi eyodwa ukuze zidluliselwe.

2. Ibanga lokudlulisa eliphakathi nendawo kanye nebanga lokudlulisa lihlukile

Ibanga lokudluliswa kwe-100G QSFP28 SR4 optical module, i-100G QSFP28 LR4 optical module, i-100G QSFP28 PSM4 optical module kanye ne-100G QSFP28 CWDM4 optical module zihlukile.

I-100G QSFP28 SR4 optical module ivame ukusetshenziswa kanye ne-MTP multi-mode fiber. Uma isetshenziswa ne-OM3 fiber, ibanga lokudlulisela lingafinyelela ku-70m, futhi uma isetshenziswa ne-OM4 fiber, ibanga lokudlulisela lingafinyelela ku-100m.

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

I-module ye-optical ye-100G QSFP28 PSM4 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 ezahlukene

Isakhiwo sokuxhumanisa se-100G QSFP28 SR4 optical module kanye ne-100G QSFP28 PSM4 optical module ziyafana, futhi zombili zidinga isakhiwo sokuxhumanisa esinezintambo eziningi esisekelwe ku-interface ye-MMF MTP enezindlela ezingu-12. Umehluko ukuthi i-100G QSFP28 PSM4 optical module kumele isebenze ku-fiber yemodi eyodwa. I-100G QSFP28 SR4 optical module iku-fiber enezintambo eziningi.

Futhi amamojula e-optical e-100G QSFP28 LR4 kanye namamojula e-optical e-100G QSFP28 CWDM4 avame ukusetshenziswa kanye nezintambo ze-LC duplex single-mode fiber patch, kusetshenziswa isakhiwo sezintambo ze-dual-pass dual-fiber SMF.

4. Isimiso sokusebenza sihlukile

Isimiso sokusebenza se-100G QSFP28 SR4 optical module kanye ne-100G QSFP28 PSM4 optical module ziyafana ngokuyisisekelo. Lapho kuthunyelwa amasignali ekugcineni kokudlulisa, amasignali kagesi aguqulwa abe amasignali optical yi-laser array, bese edluliselwa ngokuhambisana ku-fiber optical. Lapho efika ekugcineni kokwamukela, i-photodetector array iguqula amasignali optical optical parallel abe amasignali kagesi ahambisanayo, ngaphandle kokuthi eyokuqala ikwi-fiber yemodi eminingi kanti eyesibili ikwi-fiber yemodi eyodwa.

Umgomo wokusebenza we-100G QSFP28 LR4 optical module kanye ne-100G QSFP28 CWDM4 optical module ziyafana. Zombili ziguqula amasignali kagesi angu-4 25Gbps abe amasignali optical angu-4 LAN WDM, bese ziwahlanganisa abe yisiteshi esisodwa ukuze kufezwe ukudluliselwa kwe-optical okungu-100G. Ekupheleni kokwamukela, i-module ihlukanisa okokufaka kwe-optical okungu-100G kube amasignali optical angu-4 LAN WDM, bese iziguqula zibe iziteshi zokukhipha amasignali kagesi angu-4.

Ukukhethwa kohlelo lokusebenza lwe-module ye-optical ye-100G QSFP28

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

1. Izintambo ze-fiber optic ze-Multimode phakathi kwamaswishi: 5-100m

I-module ye-optical ye-100G QSFP28 SR4 ongayikhetha, esebenzisa isikhombimsebenzisi se-MTP (ama-cores angu-8), ibanga lokudlulisela uma lisetshenziswa ne-fiber ye-OM3 multimode lingu-70m, kanti uma lisetshenziswa ne-fiber ye-OM4 multimode, ibanga lokudlulisela lingu-100m, elifanele ukudluliselwa kwebanga elifushane (Ibanga lingaphansi kwamamitha ayi-100) kunethiwekhi ye-100G.

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

Ungakhetha i-100G QSFP28 PSM4 optical module noma i-100G QSFP28 CWDM4 optical module, zombili ezifanele amanethiwekhi e-100G aphakathi nendawo namafushane. I-100G QSFP28 PSM4 optical module isebenzisa imicu ye-optical engu-8 ehambisanayo yemodi eyodwa ndawonye, ​​futhi ibanga lokudlulisela lingaba amamitha angu-500; i-100G QSFP28 CWDM4 optical module isetshenziswa kanye ne-fiber ye-optical yemodi eyodwa, futhi ibanga lokudlulisela lingafinyelela ku-2 km.

3. Ifayibha yemodi eyodwa yemodi ende: ≤10km

 ingakhetha i-100G QSFP28 LR4 optical module, isebenzisa isikhombimsebenzisi se-duplex LC, ibanga lokudlulisela lingafinyelela ku-10km uma isetshenziswa nefayibha yemodi eyodwa, efanelekile kunethiwekhi yebanga elide le-100G (ibanga elingaphezu kwamakhilomitha ama-2 nangaphansi kwamakhilomitha ayi-10).

I-HUANET ingahlinzeka ngazo zonke lezi module ze-optical ze-100G QSFP28 ngentengo encintisanayo, wamukelekile ukusithumelela umbuzo.
