3. Cov txheej txheem sib txawv
Cov txheej txheem xaim ntawm 100G QSFP28 SR4 optical module thiab 100G QSFP28 PSM4 optical module yog tib yam, thiab ob qho tib si yuav tsum muaj ntau txoj hlua hluav taws xob raws li 12-txoj kev MMF MTP interface.Qhov txawv yog tias 100G QSFP28 PSM4 optical module yuav tsum ua haujlwm hauv ib hom fiber ntau Lub 100G QSFP28 SR4 optical module yog nyob rau hauv ntau hom fiber ntau.
Thiab 100G QSFP28 LR4 optical modules thiab 100G QSFP28 CWDM4 optical modules feem ntau yog siv ua ke nrog LC duplex ib hom fiber ntau thaj qaum, siv dual-pass dual-fiber SMF thaiv cov qauv.
4. Txoj haujlwm ua haujlwm txawv
Lub hauv paus ntsiab lus ua haujlwm ntawm 100G QSFP28 SR4 optical module thiab 100G QSFP28 PSM4 optical module yog qhov pib zoo ib yam.Thaum xa cov teeb liab ntawm qhov kawg ntawm kev xa tawm, cov teeb liab hluav taws xob tau hloov mus rau hauv cov teeb liab kho qhov muag los ntawm laser array, thiab tom qab ntawd xa mus rau qhov sib npaug ntawm cov khoom siv kho qhov muag.Thaum mus txog qhov kawg tau txais, Lub photodetector array converts parallel optical signals mus rau hauv parallel hluav taws xob signals, tshwj tsis yog tias tus qub yog nyob rau hauv ntau hom fiber ntau thiab tom kawg yog ntawm ib hom fiber ntau.
Lub hauv paus ntsiab lus ua haujlwm ntawm 100G QSFP28 LR4 optical module thiab 100G QSFP28 CWDM4 optical module yog tib yam.Lawv ob leeg hloov 4 25Gbps hluav taws xob teeb liab mus rau 4 LAN WDM kho qhov muag teeb liab, thiab tom qab ntawd multiplex lawv mus rau hauv ib qho channel kom ua tiav 100G optical kis tau tus mob.Thaum kawg tau txais, lub module demultiplexes 100G optical input rau hauv 4 LAN WDM optical signals, thiab ces converts lawv mus rau hauv 4 hluav taws xob teeb liab tso zis raws.
Kev xaiv ntawm 100G QSFP28 optical module
Raws li 100G network, yuav ua li cas xaiv qhov tsim nyog 100G QSFP28 optical module tuaj yeem txiav txim siab los ntawm peb yam hauv qab no:
1. Multimode fiber optic cabling ntawm keyboards: 5-100m
Kev xaiv 100G QSFP28 SR4 optical module, uas siv MTP interface (8 cores), kev sib kis deb thaum siv nrog OM3 multimode fiber ntau yog 70m, thiab thaum siv OM4 multimode fiber ntau, kev sib kis deb yog 100m, haum rau kev sib kis luv luv (Cov. nrug tsawg dua 100 meters) hauv 100G network.
2. Ib hom fiber ntau thaiv ntawm cov keyboards:> 100m-2km
Koj tuaj yeem xaiv 100G QSFP28 PSM4 optical module lossis 100G QSFP28 CWDM4 optical module, ob qho tib si haum rau nruab nrab thiab luv luv 100G tes hauj lwm.Lub 100G QSFP28 PSM4 optical module siv 8 qhov sib txuas ib leeg-hom optical fibers ua ke, thiab kev sib kis deb li ntawm 500 meters;100G QSFP28 CWDM4 kho qhov muag module yog siv ua ke nrog ib hom kev kho qhov muag fiber ntau, thiab kev sib kis tau mus txog 2 km.
3. Ntev-hom ib hom fiber ntau: ≤10km
tuaj yeem xaiv 100G QSFP28 LR4 kho qhov muag module, nws siv duplex LC interface, kis tau tus mob mus txog 10km thaum siv ib hom fiber ntau, haum rau kev ncua deb 100G network (ntau tshaj 2 mais thiab tsawg dua 10 kilometers).
