100G QSFP28 LR4 optical module nthawi zambiri imagwiritsidwa ntchito limodzi ndi LC duplex single-mode fiber, ndipo mtunda wotumizira umatha kufika 10km.

100G QSFP28 PSM4 optical module nthawi zambiri imagwiritsidwa ntchito limodzi ndi MTP single-mode fiber, ndipo mtunda wotumizira umatha kufika 500m.

100G QSFP28 CWDM4 optical module nthawi zambiri imagwiritsidwa ntchito limodzi ndi LC duplex single-mode fiber, ndipo mtunda wotumizira umatha kufika 2km.

3. Kapangidwe kosiyana ka mawaya

Kapangidwe ka mawaya a 100G QSFP28 SR4 optical module ndi 100G QSFP28 PSM4 optical module ndi ofanana, ndipo onse amafunikira kapangidwe ka mawaya ambiri opangidwa pogwiritsa ntchito mawonekedwe a MMF MTP a 12-way. Kusiyana kwake ndikuti 100G QSFP28 PSM4 optical module iyenera kugwira ntchito mu ulusi wa single-mode. 100G QSFP28 SR4 optical module ili mu ulusi wa multi-mode.

Ndipo ma module a 100G QSFP28 LR4 optical ndi ma module a 100G QSFP28 CWDM4 optical nthawi zambiri amagwiritsidwa ntchito limodzi ndi zingwe za LC duplex single-mode fiber patch, pogwiritsa ntchito kapangidwe ka waya wa dual-pass dual-fiber SMF.

4. Mfundo yogwirira ntchito ndi yosiyana

Mfundo yogwirira ntchito ya 100G QSFP28 SR4 optical module ndi 100G QSFP28 PSM4 optical module ndizofanana. Potumiza zizindikiro kumapeto kwa kutumiza, zizindikiro zamagetsi zimasinthidwa kukhala zizindikiro za kuwala ndi laser array, kenako zimatumizidwa motsatana pa ulusi wa kuwala. Pofika kumapeto kolandira, photodetector array imasintha zizindikiro za kuwala zofanana kukhala zizindikiro zamagetsi zofanana, kupatula kuti yoyamba ili pa ulusi wa multi-mode ndipo yachiwiri ili pa ulusi wa single-mode.

Mfundo yogwirira ntchito ya 100G QSFP28 LR4 optical module ndi 100G QSFP28 CWDM4 optical module ndi yofanana. Zonsezi zimasintha ma siginecha amagetsi a 4 25Gbps kukhala ma siginecha a LAN WDM optical a 4, kenako zimawachulukitsa kukhala njira imodzi kuti zikwaniritse kutumiza kwa 100G optical. Pamapeto pake, module imachotsa ma multiplex a 100G optical input kukhala ma siginecha a LAN WDM optical a 4, kenako nkuwasintha kukhala ma njira anayi otulutsa ma siginecha amagetsi.

Kusankha kwa ntchito ya 100G QSFP28 optical module

Pansi pa netiweki ya 100G, momwe mungasankhire gawo loyenera la 100G QSFP28 optical likhoza kuganiziridwa kuchokera mbali zitatu izi:

1. Zingwe za fiber optic za multimode pakati pa ma switch: 5-100m

Module yosankha ya 100G QSFP28 SR4, yomwe imagwiritsa ntchito mawonekedwe a MTP (ma cores 8), mtunda wotumizira ukagwiritsidwa ntchito ndi ulusi wa OM3 multimode ndi 70m, ndipo ukagwiritsidwa ntchito ndi ulusi wa OM4 multimode, mtunda wotumizira ndi 100m, woyenera kutumiza mtunda waufupi (Mtunda ndi wochepera mamita 100) mu netiweki ya 100G.

2. Kulumikiza ulusi wa single-mode pakati pa ma switch: >100m-2km

Mungasankhe 100G QSFP28 PSM4 optical module kapena 100G QSFP28 CWDM4 optical module, zonse ziwiri zoyenera ma network apakati ndi afupi a 100G. 100G QSFP28 PSM4 optical module imagwiritsa ntchito ulusi 8 wofanana wa single-mode optical pamodzi, ndipo mtunda wotumizira ndi pafupifupi mamita 500; 100G QSFP28 CWDM4 optical module imagwiritsidwa ntchito limodzi ndi single-mode optical fiber, ndipo mtunda wotumizira ukhoza kufika makilomita awiri.

3. Ulusi wa mode imodzi wautali: ≤10km

 Mukhoza kusankha 100G QSFP28 LR4 optical module, imagwiritsa ntchito duplex LC interface, mtunda wotumizira uthenga ukhoza kufika 10km ikagwiritsidwa ntchito ndi ulusi wa single-mode, woyenera netiweki ya 100G yakutali (mtunda woposa makilomita awiri ndi wochepera makilomita 10).

HUANET ikhoza kupereka ma module onsewa a 100G QSFP28 optical pamtengo wopikisana, takulandirani kuti mutitumizire mafunso.
