Dab tsi yog lub tshuab kho qhov muag? - Qhia rau qhov muag transce, SFPS & Tsawg -} Cov Khoom Siv Hluav Taws Xob

IbKho qhov muag kho qhov muag(feem ntau hu ua aKho qhov muag Transceiver) Yog kub - plugots hluav taws xob sib dhos uas hloov cov cim hluav taws xob rau hauv cov cim hluav taws xob (kom tau txais). Cov qauv no yog lub interface ntawm cov cuab yeej siv network (cov hloov pauv, cov ntaub ntawv uas cia cov ntaub ntawv uas cia cov hlua khi, thiab lawv yog cov tes hauj lwm optic, thiab ntev} hault txuas.

Vim li cas kho qhov muag muaj teeb meem

Kev hloov kho kho qhov muag ua rau muaj kev sib txuas hluav taws xob ua kom haum, tus neeg muag khoom {{}} {{} agnostic, thiab enjectionable network ceev lossis ncav cuag los ntawm kev hloov optics es tsis hloov daim npav tag nrho. Qhov kev thov rau qhov kho qhov muag tau nce zuj zus raws li cov ntaub ntawv, thiab 5g contiders, thiab 5g bandwidth thiab lub zog {}} kev daws teeb meem thoob plaws cov network. Kev Tshawb Fawb Ua Lag Luam Tsis ntev los no lub chaw ua lag luam hauv ntiaj teb
 

Cov Cheebtsam Tseem Ceeb (Cas Optical Module Ua Haujlwm)

Ib qho kev hloov kho kho qhov muag muaj ob peb lub tsev tseem ceeb:

Laser / LED transmitter:Hloov cov lus qhia hluav taws xob rau hauv lub teeb. Hom muaj xws li VCSELS (nquag rau luv -}}} mus txog kev sib txuam) thiab DFB lasers (siv rau kev sib txuam ib leeg thiab ntev dua).

Phodierioode txais + Tia (thim rov qab zoo tshaj plaws):Hloov cov teeb rov qab los rau hluav taws xob cov phiajcim thiab ua kom nrov nrov.

Hloov & DSP (Digital teeb liab processor):Niaj hnub nimno siab - Cov Khoom Siv Hluav Taws Xob (PAM4) thiab DSP
Hluav Taws Xob Interface & Tus Vaj Tse Connector:Sib tw tus hloov / chaw nres nkoj server (SFP, QSFP, thiab lwm yam).

EEPROM + Dom / DDM:Khw muag khoom Module cov ntaub ntawv thiab muab tiag {- lub sij hawm kuaj mob (kub, kev kub ntxhov, kev tsis txaus siab tam sim no) los ntawm sff-8472.

Daim Ntawv Qhia & Ceev - SFP rau QSFP thiab dhau mus

Daim Ntawv Qhia Loj, Hluav Taws Xob Tshaj Tawm Hluav Taws Xob, thiab Kev Tswj Pwm Siv Hluav Taws Xob thiab yog tswj hwm los ntawm ntau {}}} QHOV CHAW LOS NTAWM QHOV KEV PAB CUAM (MSAs). Cov hom pluggable muaj xws li:

SFP (1G) thiab SFP + (10G)-} saib zoo ib yam; SFP + txhawb nqa ntau dua ceev.

SFP28 (25G){{0- tib qhov loj li SFP tab sis txhawb 25GBE.

QSFP + / QSFP28 (40G / 100g){{0- plaub kab khiav hauv ib qho module (piv txwv li, 4 {{5} g).

CFP / CFP2 / CFP4{{0-}} Cov qauv loj siv keeb kwm rau 100G / 400G kab kab sab.

Xaiv daim foos foos yog qhov tseem ceeb rau kev sib raug nrog tus neeg muag khoom ports thiab rau yav tom ntej {{}} ua pov thawj hloov khoom dua tshiab.

Qhov tseem ceeb qhia kom paub

Thaum ntsuas kev ntsuas kho qhov muag kho tshiab, tshawb xyuas cov specifications:

Cov ntaub ntawv tus nqi: e.g., 1G, 10G, 25G, 40G, 100G, 200G, 400G.

Tsov & Fiber Hom:multimode (MMF) vs ib leeg - hom (smf); SR (Luv Mus Txog, Multimode), LR (ntev mus txog, ib {}} hom), er, zr, dwdm / cwdm.

Ncav:100m rau {10+ km nyob ntawm seb yam thiab fiber ntau.

Kev noj fais fab:TSEEM CEEB RAU COV NTAUB NTAWV EARERSS {{} Thiab ib txwm sfp modules kos rau hauv ~ 1}} ceev} g +) kos ob peb watts; Tsawg - Lub Hwj Chim SFP xaiv yog tsim los txo ib qho - chaw nres nkoj fais fab.

Kev kuaj mob:Kev them nyiaj yug rau Dom / DDM (SFF-8472) yog cov qauv rau pom thiab saib xyuas.

Tsawg - Power SFP Modules: Thaum twg thiab vim li cas lawv muaj teeb meem

Lub zog yog ib qho kev ua haujlwm loj hauv cov hloov ntaub loj. Rau cov khoom siv nrog ntau txhiab chaw nres nkoj (nplooj ntoos / spine fabrics nyob rau hauv hyperscale lossis huab cov chaw nruab nrab), xaivTsawg - Power SFP ModulesLos yog cov qsfp modules tuaj yeem txo lub zog teeb thiab kub, txhim kho capex / opex. Tsawg -} Cov hlua fais fab siv tau siv cov lasers zoo, txo cov teeb meem zoo tshaj plaws, lossis tshiab silicon photonics cov tswv yim. Thaum lub zog ib qho me ntsis yog qhov kev yuav khoom, nug cov neeg xa khoom, nug cov neeg xa khoom rau datasheet lub zog curves thiab tiag- Lub ntiaj teb xeem sib ntsuas.
