Optical module yog tsim los ntawm optoelectronic li, functional circuits thiab optical interfaces.Cov khoom siv optoelectronic suav nrog kev xa tawm thiab txais qhov chaw.Optical modules feem ntau yog siv hauv kev sib txuas lus kho qhov muag, cov chaw khaws ntaub ntawv thiab lwm qhov chaw.Yog li, dab tsi yog qhov kho qhov muag module?Dab tsi yog kev siv optical modules?Tom ntej no, cia peb ua raws li tus editor ntawm Feichang Technology kom paub ntau ntxiv txog nws!
Cias muab, lub luag hauj lwm ntawm optical module yog photoelectric hloov dua siab tshiab.Qhov kawg kis tau hloov cov teeb liab hluav taws xob mus rau hauv lub teeb liab optical.Tom qab kis tau los ntawm cov khoom siv kho qhov muag, qhov kawg tau txais kev hloov pauv cov teeb liab kho qhov muag rau hauv cov teeb liab hluav taws xob.
Tsis tas li ntawd, optical modules raug cais raws li ntim thiab tuaj yeem muab faib ua:
1. XFP optical module yog kub-swappable optical transceiver ywj siab ntawm kev sib txuas lus raws tu qauv.Nws yog siv rau 10G bps Ethernet, SONET / SDH, thiab optical fiber channel.
2. SFP optical modules, me pluggable txais thiab lub teeb emitting modules (SFP), yog tam sim no dav siv.
3. GigacBiDi series ib leeg-fiber bidirectional optical modules siv WDM thev naus laus zis kom paub txog kev sib kis ntawm cov ntaub ntawv ob-txoj kev (xws li kis tau tus mob point-to-point. Tshwj xeeb, fiber ntau cov peev txheej tsis txaus, thiab ib qho fiber ntau yuav tsum tau xa ob txoj kev teeb liab ).GigacBiDi suav nrog SFP ib fiber ntau bidirectional (BiDi), GBIC ib fiber ntau bidirectional (BiDi), SFP + ib fiber ntau bidirectional (BiDi), XFP ib fiber bidirectional (BiDi), SFF ib fiber bidirectional (BiDi) thiab hais txog.
4. Hluav taws xob chaw nres nkoj module, RJ45 hluav taws xob chaw nres nkoj me me pluggable module, tseem hu ua hluav taws xob module lossis hluav taws xob chaw nres nkoj module.
5. SFF optical modules muab faib ua 2 × 5, 2 × 10, thiab lwm yam raws li lawv cov pins.
6. GBIC optical module, Gigabit Ethernet interface converter (GBIC) module.
7. PON optical module, passive optical network PON (A-PON, G-PON, GE-PON) kho qhov muag module.
8. 40Gbs high-speed optical module.
9. SDH kis tau tus mob module (OC3, OC12).
10. Cia modules, xws li 4G, 8G, thiab lwm yam.
Yog li, saib ntawm no, dab tsi yog SFP optical module?Koj puas paub cov lus teb rau lo lus nug no?Yog li, qhov kev ua haujlwm ntawm SFP optical module yog dab tsi?
SFP optical module yog kub-swappable me me pob module hauv SFP pob.Tam sim no gao tus nqi tuaj yeem ncav cuag 10.3G, thiab lub interface yog LC.SFP optical module feem ntau yog tsim los ntawm laser.Tsis tas li ntawd, SFP optical module muaj xws li: laser: nrog rau fa transmitter TOSA thiab receiver ROSA;Circuit Board IC;Cov khoom siv sab nraud suav nrog: plhaub, hauv paus, PCBA, rub lub nplhaib, buckle, xauv daim, roj hmab ntsaws.Tsis tas li ntawd, SFP optical modules tuaj yeem raug cais raws li kev ceev, wavelength, thiab hom.
Kev faib tawm
Raws li qhov ceev, muaj 155M / 622M / 1.25G / 2.125G / 4.25G / 8G / 10G, 155M thiab 1.25G tau siv ntau dua hauv kev ua lag luam.10G thev naus laus zis tau maj mam paub tab, thiab qhov kev thov tau nce siab.kev loj hlob ntawm.
Kev faib tawm wavelength
Raws li lub wavelength, muaj 850nm / 1310nm / 1550nm / 1490nm / 1530nm / 1610nm.Lub wavelength yog 850nm rau SFP multimode, qhov kis tau tus mob yog qis dua 2KM, thiab lub wavelength yog 1310/1550nm rau ib hom, thiab kis tau tus mob nyob deb tshaj 2KM.Hais txog kev hais lus, qhov no Tus nqi ntawm peb lub wavelengths yog pheej yig dua li lwm qhov peb.
Nws yog ib qho yooj yim rau confuse lub liab qab module yog tias tsis muaj logo.Feem ntau, manufacturers yuav paub qhov txawv xim ntawm lub nplhaib rub.Piv txwv li, lub nplhaib rub dub yog ntau hom thiab lub wavelength yog 850nm;xiav yog lub module nrog lub wavelength ntawm 1310nm;** lub wavelength yog 1550nm Lub module;ntshav yog ib qho module nrog lub wavelength ntawm 1490nm, thiab lwm yam.
Qauv kev faib tawm
SFP optical module multimode
Yuav luag tag nrho cov multimode optical fibers yog 50/125um los yog 62.5/125um nyob rau hauv loj, thiab bandwidth (tus nqi ntawm cov ntaub ntawv xa los ntawm lub optical fiber) feem ntau yog 200MHz mus rau 2GHz.Multi-mode optical transceivers tuaj yeem xa mus txog 5 mais ntawm ntau hom optical fibers.Siv lub teeb-emitting diodes lossis lasers ua lub teeb ci.Cov xim ntawm lub nplhaib rub lossis lub cev sab nraud yog xim dub.
SFP optical module ib hom
Qhov loj ntawm ib hom fiber ntau yog 9-10/125?m, thiab piv nrog ntau hom fiber ntau, nws muaj qhov txwv tsis pub muaj bandwidth thiab qis dua cov yam ntxwv.Ib hom optical transceiver feem ntau yog siv rau kev sib kis mus ntev, qee zaum mus txog 150 txog 200 mais.Siv LD lossis LED nrog txoj kab nqaim spectral ua lub teeb ci.
