100G QSFP28 CWDM4 optical module inowanzo shandiswa pamwe chete neLC duplex single-mode fiber, uye daro rekutumira rinogona kusvika 2km.

3. Magadzirirwo akasiyana ewaya

Maumbirwo ewaya e100G QSFP28 SR4 optical module uye 100G QSFP28 PSM4 optical module akafanana, uye ese ari maviri anoda maumbirwo ewaya akawanda akavakirwa pa interface ye12-way MMF MTP. Musiyano ndewekuti 100G QSFP28 PSM4 optical module inofanira kushanda mu single-mode fiber. 100G QSFP28 SR4 optical module iri mu multi-mode fiber.

Uye 100G QSFP28 LR4 optical modules uye 100G QSFP28 CWDM4 optical modules dzinowanzo shandiswa pamwe chete neLC duplex single-mode fiber patch cords, uchishandisa dual-pass dual-fiber SMF wiring structure.

4. Nheyo yekushanda yakasiyana

Nheyo yekushanda kwe100G QSFP28 SR4 optical module uye 100G QSFP28 PSM4 optical module zvakafanana. Pakutumira masaini kumagumo ekutumira, masaini emagetsi anoshandurwa kuita masaini ekuona ne laser array, uye obva atumirwa zvakafanana pa fiber yekuona. Pakusvika kumagumo ekugamuchira, photodetector array inoshandura masaini ekuona akafanana kuita masaini emagetsi akafanana, kunze kwekuti yekutanga iri pa fiber ye multi-mode uye yekupedzisira iri pa fiber ye single-mode.

Nheyo yekushanda kwe100G QSFP28 LR4 optical module uye 100G QSFP28 CWDM4 optical module zvakafanana. Dzese dzinoshandura masaini emagetsi e4 25Gbps kuita masaini e4 LAN WDM optical, uye dzobva dzaawedzera kuita chiteshi chimwe chete kuti awane 100G optical transmission. Pakuguma kwekugamuchira, module inobvisa masaini e100G optical muzviratidzo zve4 LAN WDM optical, uye yozoashandura kuita masaini emagetsi e4.

Sarudzo yekushandisa ye100G QSFP28 optical module

Pasi pe network ye100G, nzira yekusarudza yakakodzera 100G QSFP28 optical module inogona kutariswa kubva pazvinhu zvitatu zvinotevera:

1. Kubatanidza tambo dzefiber optic dzemhando dzakasiyana-siyana pakati pemaswichi: 5-100m

Imwe module ye optical ye100G QSFP28 SR4 inosarudzwa, inoshandisa MTP interface (8 cores), daro rekutumirwa kana richishandiswa ne OM3 multimode fiber i70m, uye kana richishandiswa ne OM4 multimode fiber, daro rekutumirwa i100m, rakakodzera kutumirwa kwedaro pfupi (Dara racho risingasviki mamita 100) mu network ye 100G.

2. Kubatanidza waya dzefaibha dzemhando imwe chete pakati pemaswichi: >100m-2km

Unogona kusarudza 100G QSFP28 PSM4 optical module kana 100G QSFP28 CWDM4 optical module, dzose dzakakodzera network dze100G dziri pakati nepfupi. 100G QSFP28 PSM4 optical module inoshandisa 8 parallel single-mode optical fibers pamwe chete, uye daro rekutumira ndere 500 metres; 100G QSFP28 CWDM4 optical module inoshandiswa pamwe chete ne single-mode optical fiber, uye daro rekutumira rinogona kusvika 2 km.

3. Faibha yemhando imwe chete ine chimiro chenguva refu: ≤10km

 inogona kusarudza 100G QSFP28 LR4 optical module, inogamuchira duplex LC interface, daro rekutumirwa rinogona kusvika 10km kana richishandiswa ne single-mode fiber, yakakodzera network ye 100G inofamba daro refu (daro rinopfuura makiromita maviri uye risingasviki makiromita gumi).

HUANET inogona kupa ma module ese aya e100G QSFP28 optical nemutengo unokwikwidzana, tinokugamuchirai kuti mutitumire mibvunzo.
