Kune optical fiber transceivers, basa guru reiyo transceiver nderekuwedzera nhanho yekutapurirana network, iyo inogona kuderedza chirema chekuti network tambo haigone kuendesa kure-kure kune imwe nhanho, uye kuunza nyore kune yekupedzisira makiromita kutapurirana, asi kune avo. avo vari vatsva kune transceiver Zvimwe zvezvikanganiso zvinowanzoitwa nevanhu, zvakadai sokusasiyanisa kwekuguma kwekutumira uye kupera kwekugamuchira kwefiber optic transceiver.Sei fiber optic transceivers yakakamurwa kuita transmitter uye inogamuchira?Ko iyo A/B inopera yefiber optic transceiver ingangobatanidzwa zvisina tsarukano here?

Iyo ab magumo eiyo fiber optic transceiver inofanirwa kunge iri yekutumira magumo (kuguma) uye yekugamuchira yekupedzisira (b kuguma).Chikonzero nei transceiver yakakamurwa kuva magumo ekutumira uye kuguma kwekugamuchira ndeyekuti transceiver inoda kuendesa chiratidzo bidirectionally kana ichishandiswa, kazhinji vari vaviri vaviri.Vanhu vakawanda vanoshandisa single-fiber transceivers pamusika;Migumo miviri ye-single-fiber transceiver ndiyo A-kuguma uye B-kuguma zvakateerana.Mawavelengths pamativi maviri aya akasiyana.Iyo wavelength yemagumo ekutumira ipfupi pane iyo yekugamuchira yekupedzisira.Muchokwadi, iyo mbiri-fiber transceiver haina A uye B inogumira, nekuti wavelengths kumagumo ese akafanana.Chete kana uchibatanidza iyo TX (kutumira) magumo uye iyo RX (kugamuchira) kuguma, imwe fiber, sezita rinoratidza, ndeye optical fiber, uye dzimwe nyanzvi dzinoidaidza kuti single-core transceiver, iyo inoreva kutumira uye kugamuchira zviratidzo pamagumo ose pane imwe optical fiber, nokuti mu-single-mode The optical module inoshandiswa mukati me-single-fiber transceiver ine marefu maviri echiedza chakabudiswa, asi iyo mbiri-fiber inopindirana-yakabatanidzwa nemagetsi maviri optical, uye mukati optical film. block ine wavelength imwe chete.

Optical fiber transceivers yakakamurwa kuva single-mode dual-fiber optical fiber transceivers uye single-mode single-fiber optical fiber transceivers maererano nehuwandu hwefiber cores.I-single-mode single-fiber transceiver inotapurirwa kuburikidza ne-core optical fiber, saka zvose zvinopfuudzwa uye zvakagamuchirwa chiedza zvinoparidzirwa kuburikidza ne-one optical fiber core panguva imwe chete. kushandiswa kusiyanisa.Nokudaro, optical module ye-single-mode single-fiber transceiver ine marefu maviri echiedza, kazhinji 1310nm / 1550nm, uye kureba i1490nm / 1550nm.Nenzira iyi, pachava nekusiyana pakati pemigumo miviri yekubatana kwepairi ye transceivers, uye imwe mugumo we transceiver ichave yakasiyana.Tumira 1310nm uye ugamuchire 1550nm.Imwe magumo ndeyekutumira 1550nm uye kugamuchira 1310nm.Saka zviri nyore kuti vashandisi vasiyanise, uye mavara anowanzo shandiswa pachinzvimbo.Zvadaro pane a-kuguma (1310nm/1550nm) uye B-kuguma (1550nm/1310nm).Vashandisi vanofanira kushandisa ab pairing.Aa kana bb kubatana hazvibvumidzwe.
