Los ntawm OM3 rau OS2: Yuav ua li cas xaiv txoj cai ntawm Fiber Optic Patch Cord rau koj daim ntawv thov?

 

Qhov Kev Txiav Txim Siab - Multimode lossis Singlemode?

Thawj qhov kev txiav txim siab hauv kev xaiv thaj cords tsis yog cov qauv tshwj xeeb, tab sis yog qhov kev txiav txim siab ntawm hom fiber ntau.

Yam ntxwv	Multimode Fiber ntau (MMF)	Singlemode Fiber (SMF)
Core Diameter	Loj (feem ntau 50µm)	Tsawg heev (9µm)
Lub teeb kis hom	Ntau hom	Tib hom
Hom Lub Teeb	LED lossis VCSEL (qis dua)	Laser Diode (LD, tus nqi siab)
Hom Advantage	Tus nqi transceiver qis dua, kev txiav tawm yooj yim dua	Bandwidth siab heev, ultra-ntev deb, tsis muaj modal dispersion
Kev txiav txim siab nqi	Tsawg fiber ntau & nqi txuas	Tsawg tus nqi fiber ntau, tab sis tus nqi laser ntau dua
Qhov txawv txav	"Short-reach, Economical"	"Long-nce, Kev ua tau zoo"

Txoj Cai Yooj Yim: Kev ncua deb txiav txim hom.

Xaiv MMF Ua Ntej: Rau feem ntau cov ntaub ntawv chaw txuas nrog (feem ntau<500m between racks), enterprise campus backbones (<550m).

Yuav tsum Xaiv SMF: Rau kev sib txuas lus ntev -haul, metro networks, Data Center Interconnect (DCI), los yog ib daim ntawv thov qhov kev ncua deb yuav tshaj 550m los yog yav tom ntej hloov mus rau high bandwidth nyob deb yuav tsum tau.

Xaiv txoj cai Multimode Optical Fiber

Thaum koj txiav txim siab siv multimode fiber ntau, koj yuav ntsib kev xaiv OM3, OM4, thiab OM5. Cov no yog cov qib sib txawv ntawm multimode fiber ntau txhais los ntawm ISO / IEC 11801 tus qauv.

1. OM3 thiab OM4: Mainstream Xaiv

Ob leeg siv 50/125μm fiber ntau thiab yog optimized rau 850nm VCSEL laser qhov chaw, ua rau lawv mainstream rau 10G/40G/100G tes hauj lwm.

OM3 ("Txhim kho Multimode"):Txhawb 10Gb/s kis tau tus mob mus txog 300 meters, tus paub tab thiab tus nqi -kev xaiv zoo.

OM4 ("Advanced Multimode"):Ntxiv optimized los ntawm OM3, txhawb 10Gb / s kis tau tus mob mus txog 400 meters thiab 40/100G kis tau tus mob mus txog 150 meters. Qhov no tam sim no yog qhov kev xaiv ntau tshaj plaws rau cov chaw tsim cov ntaub ntawv tshiab, tshwj tseg cov peev nyiaj txuas ntxiv rau kev hloov kho yav tom ntej.

2. OM5: Yav tom ntej -Poriented Wideband Multimode Fiber

OM5 yog tus qauv tshiab, tseem hu ua "Wideband Multimode Fiber" (WBMMF). Nws lub peev xwm tseem ceeb nyob hauv kev txhawb nqa luv wavelength division multiplexing (SWDM) thev naus laus zis hauv 850-950nm ntau yam.

Tus nqi tseem ceeb:Los ntawm kev siv ntau lub wavelengths dhau ib zaug multimode fiber ntau, cov ntaub ntawv ntau dua (xws li yav tom ntej 400G) tuaj yeem ua tiav kev lag luam ntau dua, thiab kev sib kis ntawm cov tshuab multimode tuaj yeem txuas ntxiv.

Kev pom zoo xaiv:Tsim nyog rau yav tom ntej- saib cov chaw zov me nyuam nrog rau yav tom ntej siab - bandwidth upgrade cov phiaj xwm (xws li kev xa tawm yav tom ntej ntawm 400G-SWDM4) thiab leej twg xav ua kom tus nqi zoo tshaj ntawm multimode. Tam sim no, yog tias cov peev nyiaj tso cai, OM5 yog qhov kev xaiv ntau tshaj plaws multimode rau yav tom ntej.

Qhov Kev Xaiv Zoo Tshaj Plaws rau Ib Leeg -Mod – OS2

Hauv ib qho - hom teb, OS2 tam sim no tsuas yog tus qauv lees paub thoob ntiaj teb. Nws hais txog qis- dej-peak ib zaug- hom fiber ntau ua raws li tus qauv G.652.D, txhawb nqa tag nrho cov kev sib txuas lus ntawm 1260nm txog 1625nm.

Core Advantages: Zoo li tsis muaj kev txwv bandwidth thiab tsis tshua muaj attenuation (feem ntau 0.4 dB / km @ 1310nm, 0.25 dB / km @ 1550nm), nrog rau kev sib kis mus txog kaum lossis ntau pua mais.

Application Scenario:

Txhua qhov ntev - kis tau tus mob (telecom nraub qaum, 5G fronthaul/backhaul).

Data Center Interconnect (DCI).

Cov txheej txheem tseem ceeb hauv cov chaw khaws ntaub ntawv nrog cov kev xav tau siab heev rau kev hloov kho kom nrawm dua yav tom ntej (xws li 400G-ZR, 800G).

Nws cov yam ntxwv qis qis qis yog qhov kev txiav txim siab thaum txuas nyiaj poob qis nruj.

Kev Txiav Txim Siab Ceev Tsob Ntoo: Cia siab tias kis tau tus mob> 550 meters?

Yog → Xaiv ib zaug -mode OS2.

Tsis yog → Mus rau kauj ruam tom ntej.

Daim ntawv thov scenario: luv- nrug kev sib txuas hauv cov chaw cov ntaub ntawv lossis kev lag luam network?

Yog → Prioritize Multi- hom.

Tus nqi ntau heev -rhiab heev, tsuas yog 10G, nrug <300 meters? → OM3.

Ntsuas kev ua tau zoo thiab tus nqi, xav tau kev txhawb nqa rau 40/100G txog 150 meters, qhov no puas yog qhov kev xaiv tseem ceeb tam sim no? → OM4.

Npaj rau yav tom ntej 400G + SWDM thev naus laus zis, nrhiav qhov ntev tshaj plaws multimode nrug? → OM5.

Tsis muaj (piv txwv li, kev siv xov tooj cua, kev saib xyuas cov chaw taws teeb, thiab lwm yam) → Rov qab mus rau kauj ruam ib; OS2 yuav xav tau.

Ceeb toom tseem ceeb: System Compatibility

Patch cord xaiv yuav tsum phim lwm yam khoom hauv lub network:

Transceiver:Xyuas kom lub transceiver kev khiav hauj lwm wavelength thiab fiber ntau zoo ib yam nrog lub thaj qaum.

Kab laug sab:Lub patch qaum hom (OM3 / OM4 / OM5 / OS2) yuav tsum tau raws nraim tib yam li qhov system qaum qaum cable hom kom txo qis kev sib txuas.

Ntxuav thiab kuaj:Txawm hais tias txoj hlua khi tau xaiv, qhov kawg - kev ntxuav lub ntsej muag thiab kev sib txuas yog cov kauj ruam kawg thiab tseem ceeb tshaj plaws kom ntseeg tau tias kev ua tau zoo raws li cov qauv.

Xaus:Qhov zoo tshaj plaws haum yog qhov kev xaiv zoo tshaj plaws. Tsis muaj "zoo tshaj" fiber ntau optic thaj qaum, tsuas yog thaj qaum "tsim" tshaj plaws rau koj qhov kev thov tshwj xeeb. OM3 muaj kev ntseeg siab nkag tau-theem affordability, OM4 sawv cev rau qhov siab tam sim no -kev ua tau zoo ntawm tus nqi-effectiveness, OM5 paving txoj kev rau ib tug multimode yav tom ntej, thiab OS2 sawv cev rau qhov kawg nyob rau hauv ntev - ntau yam kis tau tus mob peev xwm. Los ntawm kev qhia txog plaub qhov kev ncua deb, bandwidth, nqi, thiab kev npaj rau yav tom ntej, koj yuav tuaj yeem yooj yim rau kev xaiv los ntawm OM3 mus rau OS2 thiab tsim lub hauv paus zoo tshaj plaws rau koj lub network.
