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

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

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

3. Mitundu yosiyanasiyana ya mawaya

Mawonekedwe a waya wa 100G QSFP28 SR4 optical module ndi 100G QSFP28 PSM4 optical module ndi ofanana, ndipo zonsezi zimafuna makina opangira ma fiber ambiri pogwiritsa ntchito mawonekedwe a 12-way MMF MTP.Kusiyanitsa ndiko kuti 100G QSFP28 PSM4 optical module iyenera kugwira ntchito mumtundu umodzi wa fiber The 100G QSFP28 SR4 optical module ili mu multi-mode fiber.

Ndipo 100G QSFP28 LR4 optical modules ndi 100G QSFP28 CWDM4 optical modules nthawi zambiri amagwiritsidwa ntchito pamodzi ndi LC duplex single-mode fiber patch zingwe, pogwiritsa ntchito awiri-pass dual-fiber SMF wiring structure.

4. Mfundo yogwira ntchito ndi yosiyana

Mfundo yogwira ntchito ya 100G QSFP28 SR4 optical module ndi 100G QSFP28 PSM4 optical module ndizofanana.Potumiza zizindikiro pamapeto otumizira, zizindikiro zamagetsi zimasinthidwa kukhala zizindikiro za kuwala ndi laser array, ndiyeno zimafalitsidwa mofanana pa optical fiber.Ikafika pamapeto olandila, Gulu la Photodetector limatembenuza ma sign optical ofananira kukhala ma sign amagetsi ofanana, kupatula kuti yoyambayo ili pamtundu wamitundu yambiri ndipo chomalizacho chili pamtundu umodzi.

Mfundo yogwira ntchito ya 100G QSFP28 LR4 optical module ndi 100G QSFP28 CWDM4 optical module ndi yofanana.Onse awiri amasintha zizindikiro zamagetsi za 4 25Gbps mu 4 LAN WDM optical signals, ndiyeno amawachulukitsa mu njira imodzi kuti akwaniritse 100G optical transmission.Pamapeto olandira, module demultiplexes 100G optical input mu 4 LAN WDM optical signals, ndiyeno amawatembenuza kukhala 4 magetsi otulutsa magetsi.

Kusankhidwa kwa 100G QSFP28 Optical module

Pansi pa intaneti ya 100G, momwe mungasankhire 100G QSFP28 optical module yoyenera ingaganizidwe kuchokera kuzinthu zitatu izi:

1. Multimode CHIKWANGWANI chamawonedwe cabling pakati masiwichi: 5-100m

Optional 100G QSFP28 SR4 optical module, yomwe imagwiritsa ntchito mawonekedwe a MTP (8 cores), mtunda wotumizira ukagwiritsidwa ntchito ndi OM3 multimode fiber ndi 70m, ndipo ikagwiritsidwa ntchito ndi OM4 multimode fiber, mtunda wotumizira ndi 100m, woyenera kufalitsa mtunda waufupi (The mtunda ndi wochepera 100 metres) mu network ya 100G.

2. Wiring wamtundu umodzi wa fiber pakati pa masiwichi:> 100m-2km

Mukhoza kusankha 100G QSFP28 PSM4 optical module kapena 100G QSFP28 CWDM4 optical module, onse omwe ali oyenerera ma 100G apakati ndi apakati.The 100G QSFP28 PSM4 optical module imagwiritsa ntchito 8 yofanana imodzi-mode optical fibers palimodzi, ndipo mtunda wotumizira uli pafupi mamita 500;100G QSFP28 CWDM4 optical module imagwiritsidwa ntchito pamodzi ndi single-mode optical fiber, ndipo mtunda wotumizira ukhoza kufika 2 km.

3. Utali wamtundu umodzi wamtundu umodzi: ≤10km

 ikhoza kusankha 100G QSFP28 LR4 optical module, imagwiritsa ntchito mawonekedwe a duplex LC, mtunda wotumizira ukhoza kufika ku 10km ukagwiritsidwa ntchito ndi fiber single-mode, yoyenera mtunda wautali wa 100G network (mtunda woposa makilomita 2 ndi makilomita osachepera 10).

HUANET ikhoza kupereka ma modules onsewa a 100G QSFP28 ndi mtengo wampikisano, mwalandiridwa kuti mutitumizire kufunsa.
