Gigabit 1 Optical 2 transceiver yamagetsi ya fiber optic yokhala ndi chip chapamwamba kwambiri

Kodi mungasankhe bwanji fiber optic transceiver?

Ma transceivers opangira ma fiber amaphwanya malire a 100-mita a zingwe za Efaneti potumiza deta.Kudalira tchipisi tapamwamba kwambiri ndi ma cache akuluakulu, pamene akukwaniritsadi kufalitsa kosatsekereza ndi kusinthana ntchito, amaperekanso magalimoto oyenerera, kudzipatula ndi mikangano.Kuzindikira zolakwika ndi ntchito zina zimatsimikizira chitetezo chokwanira komanso kukhazikika panthawi yotumiza deta.Chifukwa chake, zinthu zopangidwa ndi fiber optic transceiver zidzakhalabe gawo lofunikira kwambiri pakumanga kwa maukonde kwa nthawi yayitali.Ndiye, tiyenera kusankha bwanji ma transceivers a fiber optic?

1. Kuyesa ntchito padoko
Yesani makamaka ngati doko lililonse limatha kugwira ntchito bwino mu duplex state ya 10Mbps, 100Mbps ndi theka-duplex state.Nthawi yomweyo, iyenera kuyesedwa ngati doko lililonse litha kusankha liwiro lapamwamba kwambiri ndikufananiza ndi kuchuluka kwa zida zina.Mayesowa akhoza kuphatikizidwa mu mayesero ena.

2. Kuyesa kogwirizana
Imayesa kuthekera kolumikizana pakati pa cholumikizira cha fiber ndi zida zina zomwe zimagwirizana ndi Ethernet ndi Fast Ethernet (kuphatikiza netiweki khadi, HUB, switch, optical network card, ndi optical switch).Chofunikiracho chiyenera kuthandizira kugwirizana kwa zinthu zogwirizana.

3. Makhalidwe olumikizira chingwe
Yesani kuthekera kwa fiber optic transceiver kuthandizira zingwe za netiweki.Choyamba, yesani kugwirizana luso la Category 5 zingwe maukonde ndi utali wa 100m ndi 10m, ndi kuyesa luso kugwirizana kwa yaitali Category 5 zingwe maukonde (120m) a zopangidwa zosiyanasiyana.Pakuyesa, doko la kuwala kwa transceiver likufunika kuti likhale ndi kugwirizana kwa 10Mbps ndi mlingo wa 100Mbps, ndipo apamwamba kwambiri ayenera kugwirizanitsa ndi 100Mbps yodzaza ndi duplex popanda zolakwa zotumizira.Gulu 3 zingwe zopotoka sizingayesedwe.Ma subtest atha kuphatikizidwa mu mayeso ena.

4. Makhalidwe opatsirana (kutayika kwapaketi yapaketi yautali wosiyanasiyana, kuthamanga kwa kufalitsa)
Imayesa kutayika kwa paketi pamene doko la optical fiber transceiver optical limatumiza mapaketi osiyanasiyana a data, ndi liwiro la kulumikizana pansi pamitengo yolumikizirana yosiyana.Pakutayika kwa paketi, mutha kugwiritsa ntchito pulogalamu yoyeserera yoperekedwa ndi netiweki khadi kuyesa kutayika kwa paketi pomwe kukula kwa paketi ndi 64, 512, 1518, 128 (ngati mukufuna) ndi ma byte 1000 (posankha) pamitengo yolumikizirana yosiyana., chiwerengero cha zolakwika za paketi, chiwerengero cha mapaketi otumizidwa ndi kulandiridwa ayenera kukhala oposa 2,000,000.Kuthamanga kwa mayeso atha kugwiritsa ntchito Perform3, ping ndi mapulogalamu ena.

5. Kugwirizana kwa makina onse ku protocol yotumizira maukonde
Imayesa makamaka kugwirizana kwa ma transceivers a fiber optic ku ma protocol a netiweki, omwe amatha kuyesedwa mu Novell, Windows ndi madera ena.Ma protocol otsika otsika a netiweki monga TCP/IP, IPX, NETBIOS, DHCP, etc. ayenera kuyesedwa, ndipo ma protocol omwe akuyenera kuulutsidwa ayenera kuyesedwa.Ma transceivers owoneka amafunikira kuti athandizire ma protocol awa (VLAN, QOS, COS, etc.).

6. Mayeso a chizindikiro
Yesani ngati mawonekedwe a kuwala kowonetserako akugwirizana ndi kufotokozera kwa gululo ndi buku la ogwiritsa ntchito, komanso ngati zikugwirizana ndi zomwe zilipo panopa za fiber optic transceiver.
