Kwa optical fiber transceivers, ntchito yayikulu ya transceiver ndikukulitsa mtunda wotumizira ma netiweki, zomwe zimatha kuchepetsa vuto lomwe chingwe cha netiweki sichingatumize mtunda wautali mpaka pamlingo wina, ndikubweretsa mwayi wopita kumtunda wotsiriza wamakilomita, koma kwa iwo. omwe ali atsopano kwa transceiver Zina mwa zolakwika zomwe zimachitika kawirikawiri zimapangidwa ndi anthu, monga kusazindikirika kwa mapeto otumizira ndi kulandira mapeto a fiber optic. transceiver. Chifukwa chiyani ma transceivers a fiber optic amagawidwa kukhala ma transmitter ndi olandila? Kodi mapeto a A/B a fiber optic transceiver angalumikizidwe mwachisawawa?

Mapeto a fiber optic transceiver ayenera kukhala mapeto otumizira (mapeto) ndi mapeto olandira (b end). Chifukwa chomwe transceiver imagawika kumapeto kwa kutumiza ndipo mapeto olandira ndi chakuti transceiver amafunika kutumiza chizindikirocho bidirectionally pamene chikugwiritsidwa ntchito, kawirikawiri awiriawiri. Anthu ambiri amagwiritsa ntchito ma transceivers a fiber single pamsika; Mapeto awiri a transceiver a single-fiber ndi A-end ndi B-end motsatana. Mafunde a mafunde kumbali ziwirizi ndi zosiyana. Kutalika kwa mafunde a malekezero otumizira ndiafupi kuposa a kumapeto kolandira. M'malo mwake, transceiver yawiri-fiber ilibe malekezero a A ndi B, chifukwa kutalika kwa mafunde kumalekezero onse ndi ofanana. Pokhapokha polumikiza mapeto a TX (kutumiza) ndi mapeto a RX (kulandira), chingwe chimodzi, monga momwe dzinalo likusonyezera, ndi chingwe cha kuwala, ndipo akatswiri ena amachitcha kuti transceiver imodzi, yomwe imatanthawuza kutumiza ndi kulandira. chizindikiro pamapeto onse awiri pa chingwe chimodzi cha kuwala, chifukwa mu single-mode Optical module yomwe imagwiritsidwa ntchito mkati mwa transceiver ya single-fiber ili ndi mafunde awiri a kuwala kotulutsidwa, pamene ulusi wapawiri umalumikizidwa ndi ulusi wamaso awiri, ndipo chotchinga chamkati cha filimu chimakhala ndi utali umodzi wokha.

Ma transceivers opangira mawonekedwe amagawidwa kukhala ma single-mode dual-fiber optical fiber transceivers ndi single-mode single-fiber optical fiber transceivers malinga ndi kuchuluka kwa fiber cores. The single-mode single-fiber transceiver imafalitsidwa kudzera mu core optical fiber, kotero kuti kuwala komwe kumaperekedwa ndi kulandiridwa kumafalikira kudzera mumtundu umodzi wa fiber core panthawi imodzimodzi. amagwiritsidwa ntchito kusiyanitsa. Choncho, mawonekedwe a kuwala kwa single-mode single-fiber transceiver ali ndi mafunde awiri a kuwala, kawirikawiri 1310nm / 1550nm, ndipo mtunda wautali ndi 1490nm / 1550nm. Mwanjira iyi, padzakhala kusiyana pakati pa malekezero awiri a kugwirizana kwa awiri a transceivers, ndipo mapeto amodzi a transceiver adzakhala osiyana. Tumizani 1310nm ndikulandila 1550nm. Mapeto ena ndikutumiza 1550nm ndikulandila 1310nm. Chifukwa chake ndikosavuta kwa ogwiritsa ntchito kusiyanitsa, ndipo zilembo zimagwiritsidwa ntchito m'malo mwake. Kenako pali mapeto (1310nm/1550nm) ndi B-end (1550nm/1310nm). Ogwiritsa ntchito ab pairing. Kulumikizana kwa Aa kapena bb sikuloledwa.
