Ndeupi misiyano pakati pe-single-mode optical modules uye akawanda-mode optical modules uye maitiro ekuasarudza?

Nekukurumidza kukurumidza kwe data data uye 5G applications, optical modules zvishoma nezvishoma inozivikanwa nevanhu vakawanda uye yakashandiswa zvakanyanya. Sezvatinoziva tese, optical modules inogona kusiyaniswa zvinoenderana nemhando dzeparameter, senge single-mode Optical module uye multi-mode Optical module yatinowanzo taura. Unoziva here kuti single-mode uye multi-mode zvinorevei mune single-mode Optical modules uye multi-mode Optical modules? Ndeupi misiyano pakati pe-single-mode optical modules uye akawanda-modhi optical modules? Ungasarudza sei pakati pemamiriro akasiyana ekushandisa? Ichi chinyorwa chichakuudza mutsauko pakati pezviviri zvakadzama uye kuti ungasarudza sei mubvunzo, unogona kuverenga nemibvunzo.

1.Ndeipi single-mode optical modules uye multi-mode optical modules?

Optical modules yakakamurwa kuita single-mode optical modules uye akawanda-mode optical modules zvinoenderana neanoshanda optical fiber marudzi. Iyo optical fiber wavelength ye single-mode optical modules ndeye 1310nm, 1550nm uye WDM wavelength, nepo optical fiber wavelength ye-multi-mode optical modules ndeye 850nm kana 1310nm. Parizvino, iyo optical fiber wavelength inonyanya 850nm. Single-mode optical module uye multi-mode optical module Imwe-mode optical module uye yakawanda-mode optical module inoreva nzira yekufambisa yeoptical fibers mune optical module. Nokudaro, dzinofanirwa kushandiswa pamwe chete ne-single-mode optical fibers uye multi-mode optical fibers. Mutsara dhayamita ye single-modhi optical fibers ndeye 9/125μm, uye mutsara dhayamita ye-multi-mode optical fibers ndeye 50/125μm kana 62.5/125μm.

2.Kusiyana pakati pe-single-mode optical module uye multi-mode optical module

Muchokwadi, iyo single-mode optical module uye iyo yakawanda-mode optical module haisi kungosiyana chete mumhando yefiber inoshandiswa, asiwo yakasiyana mune zvimwe zvinhu, sezvinoratidzwa pasi apa:

①Chinhambwe chekufambisa

Single-mode optical modules inowanzoshandiswa kuendesa kure-kure, uye kureba kwekufambisa kwe-single-mode optical modules yakasiyana neyakasiyana optical fiber wavelengths. Iyo single-mode optical module ine optical fiber wavelength ye1310nm ine kurasikirwa kukuru asi kupararira kudiki panguva yekufambisa, uye kureba kwekufambisa kunowanzo mukati me40km, nepo single-mode optical module ine optical fiber wavelength ye1550nm ine kurasikirwa kudiki asi kupararira kukuru panguva yekutapurirana, uye kureba kwekufambisa kunowanzo kupfuura 40km, uye kure kwazvo kunogona kutapurirwa zvakananga pasina relay 120km. Multi-mode optical modules anowanzo shandiswa kufambisa-pfupi kufambisa, uye kureba kwekufambisa kunowanzo kuve mukati me300 kusvika 500m.

②Chikamu chekushandisa

Kubva pane sumo iri pamusoro, zvinogona kuoneka kuti single-mode optical modules inowanzoshandiswa mumambure ane marefu ekutapurirana nzendo uye yakakwirira kutapurirana mazinga, senge metropolitan area network uye passive optical fiber network, nepo multi-mode optical modules inowanzoshandiswa mukati. network ine mapfupi ekufambisa madaro uye yakaderera mitengo yekutapurirana, senge data center midziyo yemakamuri uye netiweki yenharaunda.

③Illuminant

Chiedza chechiedza chinoshandiswa ne-single-mode optical module uye multi-mode optical module yakasiyana, chiedza chechiedza chinoshandiswa ne-single-mode optical module chiedza chinobudisa diode kana laser, uye chiedza chinoshandiswa ne-multi-mode. Optical module iLD kana LED.

④Kubvisa simba

Iko kushandiswa kwesimba kwema single-mode optical modules kazhinji yakakura kupfuura yeakawanda-mode optical modules, asi simba rekushandisa kwe optical modules rinonyanya kutariswa nezvinhu zvakaita sema paramita, modhi uye mhando yeiyo optical module, saka mashandisiro emagetsi. ye single-mode optical modules ine akasiyana paramita, modhi uye mabhureki achave akafanana.

⑤Mutengo

Kuenzaniswa ne-multi-mode optical modules, single-mode optical modules inoshandisa nhamba yakakura yezvigadzirwa, kushandiswa kwelaser light source kunodhura, saka mutengo we single-mode optical modules wakakwirira kudarika mutengo we-multi-mode optical modules. .

3.Ungasarudza sei single-mode optical module uye multi-mode optical module?

Sezvambotaurwa pamusoro apa, single-mode optical modules uye multi-mode optical modules zvakasiyana maererano nekufamba kure, kushandiswa kwekushandiswa, kushandiswa kwechiedza chechiedza, simba rekushandisa uye mutengo, saka sarudzo inoda kuenderana nemamiriro chaiwo ekushanda. Semuenzaniso, iyo metropolitan area network ine kureba kwekutapurirana chinhambwe inofanira kusarudza imwe-mode optical module, uye nharaunda yenzvimbo ine mapfupi ekufambisa chinhambwe anofanira kusarudza akawanda-mode optical module. Mumashoko akareruka, ma-multi-mode optical modules anofanira kusarudzwa munharaunda yetiweki ine node dzakawanda, dzakawanda zvinobatanidza, mabhendi akawanda uye yakawanda yezvibatanidza uye ma-couplers, uye single-mode optical modules inofanira kusarudzwa mumitsetse yakareba yetrunk.

4.Summarize

Kuburikidza nesumo iri pamusoro, ndinotenda iwe unofanirwa kuve nekunzwisisa kwakajeka kwe-single-mode optical modules uye akawanda-mode optical modules. Kuti udzivise kutadza kwekubatanidza, zvinokurudzirwa kuti usarudze single-mode Optical module kana multi-mode Optical module zvinoenderana neyako chaiyo application mamiriro. Zvinonyanya kukosha, zviri nani kuti usasanganise imwe-mode optical fiber ine single-mode optical module.
