Mgbe a na-ebufe akara ngosi na njedebe nnyefe, a na-agbanwe akara eletrik ka ọ bụrụ akara ngosi anya site na usoro laser, wee bufee ya n'otu ụzọ na eriri optical. Mgbe ọ na-eru njedebe nnata, usoro nchọpụta foto na-agbanwe akara ngosi anya yiri ya ka ọ bụrụ akara eletrik yiri ya, ewezuga na nke mbụ dị na eriri ọtụtụ ụdị na nke ikpeazụ dị na eriri otu ụdị.
Ụkpụrụ ọrụ nke modulu optical 100G QSFP28 LR4 na modulu optical 100G QSFP28 CWDM4 bụ otu. Ha abụọ na-agbanwe akara eletriki 4 25Gbps ka ọ bụrụ akara optical LAN WDM anọ, wee tinye ha n'otu ọwa iji nweta nnyefe optical 100G 100G. Na njedebe nnata, modulu ahụ na-ewepụ ntinye optical 100G ka ọ bụrụ akara optical LAN WDM anọ, wee tụgharịa ha ka ọ bụrụ ọwa mmepụta akara eletriki anọ.
Nhọrọ ngwa nke modulu optical 100G QSFP28
N'okpuru netwọk 100G, otu esi ahọrọ modulu optical 100G QSFP28 kwesịrị ekwesị nwere ike ịtụle site na akụkụ atọ ndị a:
1. Njikọ eriri optic multimode dị n'etiti mgba ọkụ: 5-100m
Modulu anya 100G QSFP28 SR4 nke nhọrọ, nke na-eji njikọ MTP (isi 8), anya nnyefe mgbe ejiri eriri multimode OM3 mee ihe bụ 70m, ma mgbe ejiri ya na eriri multimode OM4 mee ihe, anya nnyefe bụ 100m, dabara adaba maka nnyefe dị mkpirikpi (Ogologo ya erughị mita 100) na netwọk 100G.
2. Wire eriri otu ụdị n'etiti swiitị: >100m-2km
Ị nwere ike ịhọrọ modulu optical 100G QSFP28 PSM4 ma ọ bụ modulu optical 100G QSFP28 CWDM4, ha abụọ dabara adaba maka netwọk 100G dị n'etiti na dị mkpụmkpụ. Modulu optical 100G QSFP28 PSM4 na-eji eriri optical 8 yiri nke otu ụdị, ebe ogologo nnyefe dị ihe dị ka mita 500; a na-eji modulu optical 100G QSFP28 CWDM4 yana eriri optical otu ụdị, ebe ogologo nnyefe nwere ike iru kilomita 2.
3. Eriri ụdị otu ụdị ogologo: ≤10km
nwere ike ịhọrọ modulu optical 100G QSFP28 LR4, ọ na-anabata njikọ LC duplex, anya nnyefe nwere ike iru 10km mgbe ejiri eriri otu ụdị, dabara adaba maka netwọk 100G dị anya (anya karịrị kilomita 2 na ihe na-erughị kilomita 10).
HUANET nwere ike inye modulu anya 100G QSFP28 ndị a niile na ọnụahịa asọmpi, biko zitere anyị ajụjụ.
