Fiber optics nthawi zambiri imakonda m'mafakitale osiyanasiyana chifukwa chakuchita bwino kwambiri komanso kutha kufalitsa deta. Mwanjira imeneyi, mutha kusamutsa deta popanda kukhudzidwa ndi zosokoneza zakunja ndi zamkati. Kupatsirana kumachitika kudzera mumitundu yambiri kapena ulusi wa single-mode kutengera kufunikira kolumikizana.

Pakusintha kwa fiber mode, mitundu yosiyanasiyana yosinthira imafunika pomwe mtunda uli wofunikira kwambiri pamawonekedwe amagetsi. MM fiber media converter ingathandize kupanga malo otetezeka otumizira deta mkati mwa makina owoneka bwino kapena zigawo.

Ma Cable a single-Mode ndi Multi-Mode
Zingwe zamtundu umodzi zimapangidwira kuti zinyamule kuwala molunjika pansi pa ulusi. Ili ndi njira imodzi yotumizira deta ndi mainchesi 8.5-10 pomwe ma multimode nthawi zambiri amakhala abwino pamtunda wamfupi. Poyerekeza ndi ma multi-mode, zingwe zamtundu umodzi zimakhala ndi bandwidth yapamwamba koma zimafunikira gwero la kuwala kokhala ndi mawonekedwe opapatiza.

Ulusi wamitundu yambiri amanyamula bandwidth yayikulu pa liwiro lalikulu. Zingwe zomwe zimayenda motalika kuposa 914,4 metres, zingwe zingapo zimatha kuyambitsa kusokonezeka pakulandila, zomwe zimayambitsa kusatsimikizika komanso pang'ono.

Pamene Kutembenuka Kukufunika?
Netiweki ya fiber optic simangogwiritsa ntchito mtundu umodzi wa ulusi, koma nthawi zambiri, mungafunike kusintha mawonekedwe panthawi yotumizira deta, makamaka MMF kupita ku SMF. Kusintha kwamachitidwe pakati pa MM ndi SM fiber nthawi zambiri kumafunika ngati mtunda wa netiweki ukuposa malire a MM fiber.

Komanso, kutembenuka kwa MMF ndi SMF kumafunika kutengera zida ndi mtundu wamalumikizidwe pamaneti. Mwachitsanzo, gawo la cholowa chotsika mtengo limagwiritsa ntchito doko la MM ndipo kulumikizana ndikofunikira pagawo la SM.

Momwe mungasinthire Multi-Mode kukhala Single-Mode?
Monga kutembenuka kwamachitidwe mu network ya optical kumaonedwa kuti ndi chilengedwe chonse, pali njira zitatu zosinthira ma multimode kupita ku single-mode. Tiyeni tiwone nawo:

Fiber kuti Fiber Media Converter
Fiber to fiber media converter ikhoza kukhala yankho lothandiza kupititsa patsogolo netiweki ya MM kupita ku ma SM fibers okhala ndi mtunda wa makilomita 140.

WDM Transporter
WDM transporter yomwe imagwiritsidwa ntchito pamakina a WDM, makamaka m'makina a DWDM chifukwa pakapita nthawi yayitali, kutembenuka kwa MMF kupita ku SMF kapena SMF kupita ku MMF kumafunika.

Mode Conditioning Fiber Patch Cord
Chingwe chowongolera chigamba cha Mode chimayambitsa laser pamayendedwe olondola kuchokera pakati pa MM fiber. Izi zimabweretsa kufalikira kwa laser m'mimba mwake mwa fiber core, kuchepetsa mphamvu yomwe imadziwika kuti differential mode delay (DMD) yomwe imachitika laser ikalowa pamitundu yaying'ono ya MM fiber.

Fiber media converter ndi njira yabwino yolumikizirana ndi intaneti yomwe ingathandize kulumikiza ndi kutumiza ma siginecha pakati pa ma fiber optic cabling ndi mitundu ina ya ma cabling media monga zingwe zamkuwa za Ethernet ndi UTP (zopindika zosatetezedwa).

Itha kuthandizira kukulitsa moyo wa zida zama netiweki ndi mbewu zamawaya. Muyenera kulumikizana ndi fiber optic pamene mtunda pakati pa zida ziwiri za netiweki ukuposa mtunda wotumizira wa cabling yamkuwa.
