100G QSFP28 PSM4 optique module ikoreshwa hamwe na fibre ya MTP imwe, kandi intera yo kohereza ishobora kugera kuri metero 500.

100G QSFP28 CWDM4 optique module ikoreshwa hamwe na fibre ya LC duplex single-mode, kandi intera yo kohereza ishobora kugera kuri 2km.

3. Imiterere itandukanye y'insinga

Imiterere y'insinga za module optique ya 100G QSFP28 SR4 na module optique ya 100G QSFP28 PSM4 ni imwe, kandi zombi zisaba insinga nyinshi zishingiye ku buryo bwa MMF MTP bw'inzira 12. Itandukaniro ni uko module optique ya 100G QSFP28 PSM4 igomba gukora muri fibre imwe. Module optique ya 100G QSFP28 SR4 iri muri fibre nyinshi.

Kandi module za optique za 100G QSFP28 LR4 na module za optique za 100G QSFP28 CWDM4 zikoreshwa hamwe n'imigozi ya LC duplex single-mode fiber patch, hakoreshejwe imiterere y'insinga za SMF zigendanwa ebyiri.

4. Ihame ry'imikorere riratandukanye

Ihame ry'imikorere rya module optique ya 100G QSFP28 SR4 na module optique ya 100G QSFP28 PSM4 muri rusange ni rimwe. Mu gihe cyo kohereza ibimenyetso ku mpera yo kohereza, ibimenyetso by'amashanyarazi bihindurwamo ibimenyetso optique na lazeri, hanyuma bigahita byoherezwa mu buryo bungana kuri fibre optique. Iyo bigeze ku mpera yo kwakira, photodetector array ihindura ibimenyetso optique parallel mo ibimenyetso optique parallel, uretse ko iya mbere iri kuri fibre multi-mode naho iya nyuma ikaba iri kuri fibre imwe-mode.

Ihame ry'imikorere rya module optique ya 100G QSFP28 LR4 na module optique ya 100G QSFP28 CWDM4 ni bimwe. Byombi bihindura ibimenyetso by'amashanyarazi bya 4 25Gbps mo ibimenyetso by'amashanyarazi bya LAN WDM 4, hanyuma bikabyongera mu muyoboro umwe kugira ngo bigere ku kohereza kwa optique kwa 100G. Ku mpera yo kwakira, module igabanya uburyo bwinshi bwo kwinjiza 100G mu bimenyetso by'amashanyarazi bya LAN WDM 4, hanyuma ikabishyiramo imiyoboro 4 y'amashanyarazi isohora ibimenyetso.

Guhitamo porogaramu ya module optique ya 100G QSFP28

Mu rwego rwa 100G, uburyo bwo guhitamo module ikwiye ya 100G QSFP28 optique bushobora gusuzumwa hakurikijwe ibintu bitatu bikurikira:

1. Insinga za fiber optique za multimode hagati y'amaswichi: 5-100m

Uburyo bworoshye bwo kohereza amakuru bwa 100G QSFP28 SR4, bukoresha uburyo bwa MTP (cores 8), intera yo kohereza amakuru iyo ikoreshejwe na fibre ya OM3 multimode ni metero 70, naho iyo ikoreshejwe na fibre ya OM4 multimode, intera yo kohereza amakuru ni metero 100, ikaba ikwiriye kohereza amakuru mu ntera ngufi (intera iri munsi ya metero 100) muri network ya 100G.

2. Insinga z'umugozi umwe hagati y'amadirishya: >100m-2km

Ushobora guhitamo module ya optique ya 100G QSFP28 PSM4 cyangwa module ya optique ya 100G QSFP28 CWDM4, zombi zikwiriye imiyoboro ya 100G iri hagati n'iy'intera ngufi. Module ya optique ya 100G QSFP28 PSM4 ikoresha imiyoboro 8 ya optique ihuriweho, kandi intera yo kohereza ni metero 500; module ya optique ya 100G QSFP28 CWDM4 ikoreshwa hamwe na fibre ya optique iri kumwe, kandi intera yo kohereza ishobora kugera kuri kilometero 2.

3. Fibre y'uburyo bumwe bwo mu buryo burebure: ≤10km

 irashobora guhitamo module ya optique ya 100G QSFP28 LR4, ikoresha interface ya duplex LC, intera yo kohereza ishobora kugera kuri 10km iyo ikoreshejwe na fibre imwe, ikwiriye umuyoboro wa 100G kure (intera irenga kilometero 2 kandi munsi ya kilometero 10).

HUANET ishobora gutanga izi modules zose za 100G QSFP28 optique ku giciro cyiza, murakaza neza kutwoherereza ikibazo.
