3. Cov qauv sib txawv ntawm cov xov hlau

Cov qauv txuas ntawm 100G QSFP28 SR4 optical module thiab 100G QSFP28 PSM4 optical module zoo ib yam, thiab ob qho tib si xav tau cov qauv txuas ntau fiber raws li 12-txoj kev MMF MTP interface. Qhov sib txawv yog tias 100G QSFP28 PSM4 optical module yuav tsum ua haujlwm hauv ib hom fiber. 100G QSFP28 SR4 optical module yog nyob rau hauv ntau hom fiber.

Thiab 100G QSFP28 LR4 optical modules thiab 100G QSFP28 CWDM4 optical modules feem ntau yog siv ua ke nrog LC duplex single-mode fiber patch cords, siv dual-pass dual-fiber SMF wiring qauv.

4. Txoj cai ua haujlwm txawv

Lub hauv paus ntsiab lus ua haujlwm ntawm 100G QSFP28 SR4 optical module thiab 100G QSFP28 PSM4 optical module yeej zoo ib yam. Thaum xa cov teeb liab ntawm qhov kawg xa, cov teeb liab hluav taws xob raug hloov mus ua cov teeb liab kho qhov muag los ntawm lub laser array, thiab tom qab ntawd xa mus rau hauv parallel ntawm cov fiber kho qhov muag. Thaum mus txog qhov kawg tau txais, Lub photodetector array hloov cov teeb liab kho qhov muag sib luag mus rau hauv cov teeb liab hluav taws xob sib luag, tsuas yog tias tus qub nyob ntawm ntau hom fiber thiab tus tom kawg nyob ntawm ib hom fiber.

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 lub teeb liab hluav taws xob 25Gbps mus rau hauv 4 lub teeb liab LAN WDM optical, thiab tom qab ntawd multiplex lawv mus rau hauv ib txoj kab ke kom ua tiav 100G optical kis tau. Ntawm qhov kawg tau txais, lub module demultiplexes 100G optical input mus rau hauv 4 lub teeb liab LAN WDM optical, thiab tom qab ntawd hloov lawv mus rau hauv 4 lub teeb liab hluav taws xob tso zis channel.

Kev xaiv daim ntawv thov ntawm 100G QSFP28 optical module

Nyob rau hauv 100G network, yuav ua li cas xaiv ib qho 100G QSFP28 optical module uas tsim nyog tuaj yeem xav txog los ntawm peb yam hauv qab no:

1. Multimode fiber optic cabling ntawm cov keyboards: 5-100m

Xaiv tau 100G QSFP28 SR4 optical module, uas siv MTP interface (8 cores), qhov kev sib kis thaum siv nrog OM3 multimode fiber yog 70m, thiab thaum siv nrog OM4 multimode fiber, qhov kev sib kis yog 100m, tsim nyog rau kev sib kis luv luv (Qhov kev ncua deb tsawg dua 100 meters) hauv 100G network.

2. Ib hom fiber ntau txuas ntawm cov keyboards: >100m-2km

Koj tuaj yeem xaiv 100G QSFP28 PSM4 optical module lossis 100G QSFP28 CWDM4 optical module, ob qho tib si yog tsim rau nruab nrab thiab luv luv 100G networks. 100G QSFP28 PSM4 optical module siv 8 parallel single-mode optical fibers ua ke, thiab qhov deb kis tau yog li 500 meters; 100G QSFP28 CWDM4 optical module siv ua ke nrog single-mode optical fiber, thiab qhov deb kis tau tuaj yeem ncav cuag 2 km.
