Isu tinotenda kuti vashandisi vazhinji vane imwe nzwisiso ye optical transceivers.Vazhinji vashandisi havazive zvakawanda nezve optical modules.Optical modules chikamu chakakosha che optical transceivers.Optical modules inonyanya kukosha kune optical transceivers, saka chii chinonzi optical module uye nei ichigona kuita basa rakakura kudaro mumatransceivers optical?

Iyo optical module ye optical transceiver inowanzoshandiswa mumusana wetiweki ye optical fiber network.Optical modules anonyanya kukamurwa kuva GBIC, SFP, SFP+, XFP, SFF, CFP, nezvimwewo, uye optical interface mhando dzinosanganisira SC uye LC.Nekudaro, SFP, SFP+, XFP inowanzoshandiswa mazuvano panzvimbo yeGBIC.Chikonzero ndechekuti GBIC yakakura uye iri nyore kuputsika.Nekudaro, iyo inowanzoshandiswa SFP idiki uye yakachipa.Zvinoenderana nerudzi, inogona kukamurwa kuita single-mode optical modules uye akawanda-mode optical modules.Single-mode optical modules inokodzera kuendesa kure-kure;ma-multi-mode optical modules akakodzera kutapurirana kwenguva pfupi.

Midziyo yeOptical iri kusimukira yakanangana neminiaturization, kuvandudza (yemagetsi / optical, optical / magetsi kutendeuka) kunyatsoita, nekuvandudza kuvimbika;planar optical waveguide (PLC) tekinoroji ichawedzera kudzikisa huwandu hwebidirectional/matatu-directional optical components uye kunatsiridza kuvimbika kwechikamu.Mabasa uye kushanda kweiyo yakabatanidzwa yedunhu machipisi yakasimbiswa, kuitira kuti vhoriyamu ye optical modules yakaderedzwa uye kushanda kwave kuchivandudzwa.Iyo sisitimu inoramba ichiisa mberi zvitsva zvinodiwa kune mamwe mabasa emodule, uye hungwaru basa reiyo optical module inofanirwa kuramba ichivandudzwa kuti isangane nezvinodiwa zvehurongwa.

Muchokwadi, mune iyo optical transceiver, kukosha kweiyo optical module inodarika iyo core chip.Iyo optical module inoumbwa neoptoelectronic zvishandiso, anoshanda maseketi uye optical interfaces.Zvichitaurwa zviri nyore, basa reiyo optical module ndeye photoelectric shanduko.Mugumo wekutumira unoshandura zviratidzo zvemagetsi kuita zviratidzo zvemaziso.Mushure mokutumira kuburikidza ne-optical fiber, kuguma kwekugamuchira kunoshandura zviratidzo zvemaziso mumagetsi emagetsi, izvo zvinonyanya kushanda uye zvakachengeteka kudarika transceivers.Mushure mekunge simba ravhurwa, iyo optical module iri munzira yekugara ichiburitsa mwenje, uye pachava nekudzikira nekufamba kwenguva.Naizvozvo, zvakakosha zvikuru kuona basa reiyo optical module.

Isu tinofanirwa kushandisa optical simba mita kuona kunaka kweiyo optical module.Kazhinji, kana iyo optical module ikabuda mufekitori, mugadziri wepakutanga anoendesa mhando yekuongorora rondedzero yeiyi batch kumugadziri wekugadzirisa.Mugadziri anoshandisa optical simba mita yekuongorora chaiko., Kana mutsauko uri mukati mehuwandu hwekuzivisa, chigadzirwa chakakodzera.

Nekukosha kwakaedzwa neiyo optical module, iyo fekitori simba renji -3 ~ 8dBm.Kuburikidza nekuenzanisa kwenhamba, iyo optical module inogona kutsanangurwa sechigadzirwa chakakodzera.Inonyanya kuyeuchidzwa kuti iyo idiki kukosha kwesimba, iyo inoshaya simba yekugona kutaura kwemaziso;ndiko kuti, iyo yakaderera-simba optical module haigone kuita kuendesa kure kure.Zvinoenderana neakakodzera masosi muindastiri, mamwe madiki mashopu anozotenga echipiri-ruoko optical modules, ayo manhamba anogadziridzwa uye anoshandiswa mune pfupi-kure optical transmission michina.Zviripachena, izvi hazvina basa zvakanyanya kune vashandisi.
