Jan 17, 2026| SFP Module Ua tiav Phau Ntawv Qhia: Hom, Specifications & Applications
Tus neeg saib xyuas kev yuav khoom los ntawm cov neeg tsim khoom tau hu rau hnub Tuesday kawg nug txog 10G module nqi. Thaum kuv hais qhov thib peb - tog SFP+-LR ntawm $ 18 ib chav, muaj ib ntus.Peb tus neeg sawv cev Cisco tau hais txog $ 399 rau tib qhov tshwj xeeb.Qhov ntawd yog 95% tus nqi sib txawv rau cov qauv uas ua haujlwm zoo ib yam.
Tus nqi sib txawv no muaj nyob thoob plaws lub khw SFP. Nws tsis yog qhov zais cia, tab sis feem ntau cov neeg yuav khoom tsis paub txog qhov ntsuas kom txog thaum lawv pom cov lej ntawm ib sab. Qhov tseem ceeb tshaj, lawv tsis paub tias qhov xwm txheej twg ua rau pom tseeb them tus nqi thiab qhov twg tsis yog.
Daim duab kos tiag
Cia kuv muab cov lej tseeb rau ntawm lub rooj vim qhov no yog qhov kev txiav txim siab yuav khoom.
OEM vs Third -Party Pricing (2024-2025 tus nqi lag luam)
| Hom Module | Cisco List Price | Thib peb -Tus nqi | Koj Cov Nyiaj Txiag |
|---|---|---|---|

Ntawm 1,000-chaw nres nkoj 10G xa tawm siv LR modules, uas yog kwv yees$950,000 hauv OEM opticspiv$35,000 nyob rau hauv sib xws modules. Qhov sib txawv pab nyiaj rau tag nrho lub network rov ua dua lwm qhov.
Cov no tsis yog ua -cov duab. Gartner thiab ntau qhov kev lag luam tshuaj ntsuam xyuas tas li qhia 50-90% kev txuag nyiaj nrog cov neeg thib peb transceivers. Peb tus kheej cov ntaub ntawv muag khoom taug qab ze nrog qhov kawg siab ntawm qhov ntau rau cov neeg yuav khoom lag luam.
Tam sim no, kuv ua haujlwm rau tus thib peb -tus neeg muab khoom, yog li pom tseeb tias kuv muaj txoj haujlwm ntawm no. Tab sis kev lag luam muaj tseeb. Cov lus nug tsis yog seb puas siv tau cov modules raug nqi tsawg dua. Cov lus nug yog seb tus nqi sib txawv puas muaj kev pheej hmoo zais uas noj rau hauv koj cov nyiaj khaws cia.
Dab tsi tiag tiag txawv SFP Modules
Txhua tus neeg tshawb nrhiav "SFP module hom" xav kom muaj kev sib cais zoo. Qhov tseeb yog messier vim hais tias tib lub cev daim ntawv tseem ceeb spans ntau tiam thiab siv cov ntaub ntawv.
Los ntawm ceev, lineup khiav:
SFP (Original)
Kov txog li 4.25 Gbps, uas npog Gigabit Ethernet thiab legacy Fiber Channel. Tseem tsim, tseem xa mus rau hauv cov txheej txheem nkag qhov twg 1G txaus.
SFP +
Txuas hluav taws xob cuam tshuam rau 10 Gbps. Qhov no yog tus thawj coj ntim tam sim no rau kev xa khoom lag luam. Mature technology, sib tw nqi, broad compatibility.
SFP28
Push mus rau 25 Gbps siv tib daim ntawv zoo. Hyperscale datacenters tsav kev saws me nyuam; tuam txhab ua raws li. 25G ib - txoj kab tus nqi sib haum nrog 100G hloov architectures (4x25G breakout).
SFP 56
Hits 50 Gbps los ntawm PAM4 kev hloov pauv. ZTE thiab Jiangsu Txawb tau ua tiav 50G PON kev sim ua ntej xyoo no siv SFP-DD ntim, ua tiav 30% me me hneev taw thiab 25% kev ua haujlwm thermal zoo dua li cov qauv dhau los. This matters for equipment density as carriers push bandwidth without replacing cabinets (zte.com.cn).
Los ntawm kis nruab nrab:
Fiber modules yeej.
Luv- ncav cuag (SX/SR) khiav 850nm hla multimode fiber ntau, feem ntau mus txog 300-550m nyob ntawm qib fiber ntau. Ntev- ncav cuag (LX/LR) khiav 1310nm dhau ib zaug - hom mus rau 10km tus qauv, nrog rau kev ncua ntev mus txog 40km, 80km, lossis deb dua.
tooj liab modules muaj.
1000BASE-T ua haujlwm zoo rau kev sib koom ua ke qub txeeg qub teg. 10GBASE-T yog zaj dab neeg sib txawv. Cov qauv no rub 2-3 watts thiab khiav ntawm 70℃+. Ib tus neeg siv aerospace daws qhov no los ntawm kev tsim kho ib puag ncig: lawv tau siv S5850-48T4Q keyboards nrog haiv neeg 10GBase-T chaw nres nkoj rau kev sib txuas ntawm server ntawm Cat6a, tom qab ntawd siv DAC cables rau uplinks. Tsis txhob tso 10G tooj liab SFPs hauv cov qauv hloov chaw nres nkoj nkaus xwb (fs.com case study).
DAC (Direct Txuas Cable) sib dhos
Bundle twinax tooj liab nrog kev sib xyaw SFP + / SFP28 connectors. Rau kev khiav qis dua 5 meters, passive DAC tus nqi 60-80% tsawg dua cov khoom siv kho qhov muag uas tsis muaj laser ua tsis tiav. Feem ntau cov kev sib txuas hauv khib nyiab poob zoo nyob rau hauv qhov kev ncua deb. Peb thawb DAC nyuaj rau ToR kev xa tawm vim tias qhov kev ntseeg siab thiab tus nqi profile yog qhov zoo dua, tsis yog vim tias cov paj tau siab dua.
Xaiv Hauv Pawg
Qhov no yog qhov "hom lus qhia" lub hom phiaj tshawb nrhiav feem ntau poob qis. Paub tias SFP-LR muaj nyob tsis tau pab koj txiav txim siab ntawm SFP-10G-LR thiab SFP-25G-LR rau ib qhov txuas tshwj xeeb.
Qhov yuav tsum tau nyob deb tsav kev xaiv fiber ntau:
| Xav tau deb | Multimode Option | Tib -mode Option | Sau ntawv |
|---|---|---|---|
| Hauv qab 100 m | SR/SX dhau OM3/OM4 | Overkill, tsis txhob nkim nyiaj | |
| 100-550m | SR dhau OM4 | LR ua haujlwm tab sis raug nqi ntau dua | Tshawb xyuas koj cov qib fiber ntau |
| 550m-10km | Tsis tau | LR txuj | |
| 10-40 km | Tsis tau | ER lossis txuas LR | Nqe jumps ho |
| 40km + | Tsis tau | ZR or DWDM | Carrier -qib, pob nyiaj raws li |
Feem ntau yuam kev yog overspecifying. Kev khiav 200-meter tsis xav tau LR. Ib qho SR module ntawm $ 12 ua haujlwm ib yam li LR ntawm $ 35. Muab ntau los ntawm ob peb puas chaw nres nkoj thiab cov khib nyiab ntxiv.
Kev ceev tier xaivnyob ntawm koj qhov kev hloov kho vaj tse ntau dua li qhov txuas lawv tus kheej. Yog tias koj cov tub ntxhais khiav 100G nrog 4x25G breakout muaj peev xwm, SFP28 ntawm ntug ua rau kev nkag siab ntawm architectural txawm tias 10G bandwidth yuav txaus hnub no. Yog tias koj nyob ntawm 10G / 40G infrastructure uas tsis muaj nyob ze - lub sijhawm hloov kho txoj kev, them tus nqi SFP28 yuav tsis muaj dab tsi.
Txoj kev txhim kho feem ntau yog khiav: ntau- txoj kab modules zoo li QSFP-DD nkag mus rau hauv kev ua lag luam ua ntej ntawm cov qib ceev tshiab, tom qab ntawd ib leeg - txoj kab SFP- qauv modules ua raws li cov thev naus laus zis loj thiab ib - tus nqi qis. SFP56 yog qhov pib ntawm qhov nkhaus tam sim no. Rau feem ntau cov neeg yuav khoom lag luam, SFP28 sawv cev rau kev coj ua thawj coj hauv xyoo 2025.
Specifications Qhov tseem ceeb rau kev yuav khoom
Qib kub yog ib qho spec tib neeg qis dua kom txog thaum ib yam dab tsi ua tsis tiav.
