100G QSFP28 LR4 optique isanzwe ikoreshwa hamwe na LC duplex imwe-fibre imwe, kandi intera yohereza irashobora kugera kuri 10km.

100G QSFP28 PSM4 optique isanzwe ikoreshwa hamwe na MTP fibre imwe-imwe, kandi intera yohereza irashobora kugera kuri 500m.

100G QSFP28 CWDM4 optique module isanzwe ikoreshwa hamwe na LC duplex imwe-fibre imwe, kandi intera yohereza irashobora kugera kuri 2km.

3. Imiterere itandukanye

Imiterere yo gukoresha insinga ya optique ya 100G QSFP28 SR4 hamwe na 100G QSFP28 PSM4 optique ni imwe, kandi byombi bisaba ibyuma bifata ibyuma byinshi bishingiye kumirongo 12 MMF MTP.Itandukaniro nuko 100G QSFP28 PSM4 module optique igomba gukora muri fibre imwe-moderi imwe ya 100G QSFP28 SR4 optique iri muri fibre yuburyo bwinshi.

Kandi 100G QSFP28 LR4 modul optique hamwe na 100G QSFP28 CWDM4 optique isanzwe ikoreshwa hamwe hamwe na LC duplex imwe-fibre fibre yamashanyarazi, ikoresheje ibyuma bibiri-byombi bya fibre SMF.

4. Ihame ry'akazi riratandukanye

Ihame ryakazi rya 100G QSFP28 SR4 module ya optique hamwe na 100G QSFP28 PSM4 optique module ni imwe.Iyo wohereza ibimenyetso kumpera yohereza, ibimenyetso byamashanyarazi bihindurwa mubimenyetso bya optique na laser array, hanyuma bigahita bigereranywa kuri fibre optique.Iyo ugeze ku ndunduro yo kwakirwa, umurongo wa Photodetector uhindura ibimenyetso bya optique muburyo bwo guhuza amashanyarazi, usibye ko iyambere iri kuri fibre yuburyo bwinshi naho iyindi iri kuri fibre imwe.

Ihame ryakazi rya 100G QSFP28 LR4 module ya optique hamwe na 100G QSFP28 CWDM4 module optique ni imwe.Bombi bahindura ibimenyetso byamashanyarazi 4 25Gbps mubimenyetso 4 bya LAN WDM, hanyuma bakabigwiza mumurongo umwe kugirango bagere kuri 100G optique.Kurangiza kwakirwa, module demultiplexes 100G optique yinjiza muri 4 LAN WDM ya optique, hanyuma ikayihindura mumiyoboro 4 yerekana amashanyarazi.

Guhitamo gusaba 100G QSFP28 module optique

Munsi ya rezo ya 100G, uburyo bwo guhitamo 100G QSFP28 optique module irashobora gutekerezwa mubice bitatu bikurikira:

1. Multimode fibre optique cabling hagati ya switch: 5-100m

Ibyifuzo 100G QSFP28 SR4 optique module, ikoresha interineti ya MTP (cores 8), intera yo kohereza iyo ikoreshejwe na fibre ya OM3 multimode ni 70m, kandi iyo ikoreshejwe na fibre ya OM4 multimode, intera yoherejwe ni 100m, ikwiranye no kohereza intera ndende (The intera iri munsi ya metero 100) murusobe rwa 100G.

2. Uburyo bumwe bwa fibre wiring hagati ya switch:> 100m-2km

Urashobora guhitamo 100G QSFP28 PSM4 module ya optique cyangwa 100G QSFP28 CWDM4 module optique, byombi bikwiranye nintera yo hagati na ngufi 100G.100G QSFP28 PSM4 optique ikoresha 8 ihuriweho na fibre optique hamwe, kandi intera yoherejwe ni metero 500;100G QSFP28 CWDM4 module ya optique ikoreshwa hamwe na fibre optique imwe, kandi intera yohereza irashobora kugera kuri 2 km.

3. Inzira ndende-imwe ya fibre: ≤10km

 irashobora guhitamo 100G QSFP28 LR4 optique module, ifata interineti ya duplex LC, intera yohereza irashobora kugera kuri 10km mugihe ikoreshejwe hamwe na fibre imwe-imwe, ikwiranye numuyoboro muremure wa 100G (intera irenga kilometero 2 na kilometero 10).

HUANET irashobora gutanga aya 100G QSFP28 optique hamwe nibiciro byapiganwa, ikaze kutwoherereza iperereza.
