Optical fiber transceiver ndi Ethernet transmission media conversion unit yomwe imasinthanitsa ma siginecha amagetsi opindika mtunda waufupi ndi ma sign atali atali. Imatchedwanso fiber converter m'malo ambiri. Zogulitsa nthawi zambiri zimagwiritsidwa ntchito pamalo enieni amtaneti pomwe zingwe za Efaneti sizingaphimbidwe ndipo ulusi wa kuwala umayenera kugwiritsidwa ntchito kukulitsa mtunda wotumizira, ndipo nthawi zambiri zimayikidwa munjira yofikira pamanetiweki a Broadband metropolitan area.

Udindo wa fiber optic transceivers

Ma fiber optic transceivers nthawi zambiri amagwiritsidwa ntchito m'malo enieni amtaneti pomwe zingwe za Efaneti sizingaphimbidwe ndipo ulusi wamaso uyenera kugwiritsidwa ntchito kukulitsa mtunda wotumizira. Nthawi yomweyo, atenganso gawo lalikulu pothandizira kulumikiza mtunda womaliza wa mizere ya optical fiber ku ma netiweki amtundu wa metropolitan ndi ma network akunja. Udindo wa. Ntchito ya fiber optic transceiver ndikusintha chizindikiro chamagetsi chomwe tikufuna kutumiza kukhala chizindikiro cha kuwala ndikuchitumiza. Panthawi imodzimodziyo, imatha kusintha chizindikiro cholandira kuwala kukhala chizindikiro chamagetsi ndikuchiyika kuti tilandire.

Gulu lafiber optic transceivers

1.Single-mode fiber optic transceiver: mtunda wotumizira kuchokera ku 20 kilomita kupita ku 120 makilomita.

2.Multimode fiber optic transceiver: kufalitsa mtunda wa makilomita 2 mpaka 5 makilomita.

Mwachitsanzo, mphamvu yotumizira ya 5km fiber optic transceiver nthawi zambiri imakhala pakati pa -20 ndi -14db, ndipo kulandira kukhudzidwa ndi -30db, pogwiritsa ntchito kutalika kwa 1310nm; pamene mphamvu yotumizira ya 120km fiber optic transceiver nthawi zambiri imakhala pakati pa -5 ndi 0dB, ndi kulandira kumva Kwa -38dB, gwiritsani ntchito kutalika kwa 1550nm.

Mawonekedwe a fiber optic transceivers

Ma fiber optic transceivers nthawi zambiri amakhala ndi izi:

1. Perekani kutumizira kwa data kotsika kwambiri.

2. Zowonekera kwathunthu ku protocol network.

3. Gwiritsani ntchito chipangizo chodzipereka cha ASIC kuti muzindikire kutumizira mwachangu kwa mzere wa data. Programmable ASIC imayang'ana ntchito zingapo pa chip imodzi, ndipo ili ndi maubwino amapangidwe osavuta, odalirika kwambiri, komanso kugwiritsa ntchito mphamvu pang'ono, zomwe zingathandize zida kupeza magwiridwe antchito apamwamba komanso kutsika mtengo.

4. Zida zamtundu wa rack zimatha kupereka ntchito yotentha yotentha kuti ikhale yosavuta kukonza ndi kukonzanso kosasokonezeka.

5. Zida zoyendetsera maukonde zingapereke ntchito monga kuzindikiritsa maukonde, kukweza, lipoti la mkhalidwe, lipoti la zochitika zachilendo ndi kulamulira, ndipo angapereke chipika chonse cha ntchito ndi chipika cha alamu.

6. Zida zambiri zimagwiritsa ntchito mapangidwe a magetsi a 1 + 1, amathandizira magetsi opangira magetsi, ndipo amazindikira chitetezo cha magetsi ndi kusintha kwachangu.

7. Thandizani kutentha kwakukulu kogwira ntchito.

8. Support wathunthu kufala mtunda (0 ~ 120 makilomita).

Ubwino wa fiber optic transceivers

Ponena za ma transceivers a fiber optic, anthu nthawi zambiri amafanizira ma fiber optic transceivers ndimasiwichindi madoko owoneka. Zotsatirazi makamaka zikukamba za ubwino wa ma transceivers a fiber optic pa doko la kuwalamasiwichi.

Choyamba, mtengo wa fiber optic transceivers kuphatikiza wambamasiwichindi otsika mtengo kwambiri kuposa kuwalamasiwichi, makamaka ena openyamasiwichiadzataya madoko amodzi kapena angapo amagetsi pambuyo powonjezera ma module optical, omwe angapangitse ogwira ntchito pamlingo waukulu Kuchepetsa ndalama zam'tsogolo.

Kachiwiri, popeza ma module ambiri a Optical amasiwichialibe muyezo wogwirizana, kamodzi kokha ma modules optical awonongeka, amafunika kusinthidwa ndi ma modules omwewo kuchokera kwa wopanga choyambirira, zomwe zimabweretsa vuto lalikulu kukonzanso pambuyo pake. opanga osiyanasiyana opanga ma transceivers a fiber optic, kotero akangowonongeka, amatha kusinthidwa ndi zinthu za opanga ena, zomwe zimakhala zosavuta kuzisamalira.

Kuphatikiza apo, ma transceivers a fiber optic ali ndi zinthu zathunthu kuposa doko la kuwalamasiwichikutengera mtunda wotumizira. Inde, kuwalakusinthailinso ndi maubwino muzinthu zambiri, monga kasamalidwe kogwirizana komanso kaphatikizidwe kamagetsi.
