Duplex CHIKWANGWANI ndi polarity
Pogwiritsira ntchito 10G Optical fiber, ma fiber awiri optical amagwiritsidwa ntchito kuzindikira njira ziwiri zotumizira deta.Mapeto amodzi a ulusi uliwonse wa kuwala amalumikizidwa ndi chotumizira ndipo mbali inayo imalumikizidwa ndi wolandila.Onsewa ndi ofunikira.Timawatcha kuti duplex optical fiber, kapena duplex optical fiber.
Mofananamo, ngati pali duplex, pali simplex.Simplex imatanthawuza kutumiza uthenga mbali imodzi.Pamalekezero onse a kulumikizana, mbali imodzi ndi yotumizira ndipo ina ndi yolandila.Mofanana ndi faucet kunyumba, deta imayenda mbali imodzi ndipo sichisinthidwa.(ndithu, pali kusamvana apa. Kunena zoona, kuyankhulana kwa optical fiber ndizovuta kwambiri. Optical fiber imatha kufalikira mbali ziwiri. Timangofuna kuti timvetsetse.)
Kubwerera ku duplex fiber, TX (b) iyenera kulumikizidwa nthawi zonse ndi RX (a) mosasamala kanthu za mapanelo angati, ma adapter kapena zigawo za chingwe cha kuwala zomwe zili pamanetiweki.Ngati polarity yofananirayo sinawonedwe, chidziwitsocho sichidzaperekedwa.
Pofuna kusunga polarity yolondola, muyezo wa tia-568-c umalimbikitsa AB polarity crossing scheme pa duplex jumper.
MPO/MTP CHIKWANGWANI polarity
Kukula kwa cholumikizira cha MPO/MTP ndi chofanana ndi cholumikizira cha SC, koma chimatha kukhala ndi ulusi wa 12/24/16/32.Chifukwa chake, MPO imatha kupulumutsa kwambiri malo opangira ma waya.
Njira zitatu za polarity zotchulidwa mu TIA568 standard zimatchedwa njira A, njira B ndi njira C motsatana.Kuti mukwaniritse muyezo wa TIA568, zingwe za MPO/MTP za msana zimagawidwanso, kuwoloka kwathunthu ndi kuwoloka awiri, monga mtundu A (makiyi mmwamba - makiyi pansi), lembani B (kiyi mmwamba - makiyi mmwamba / makiyi pansi. makiyi pansi kuwoloka kwathunthu) ndipo lembani C (kiyi mmwamba - makiyi pansi awiri kuwoloka).
Monga momwe chithunzi chili pansipa:
Pakali pano zingwe zigamba za MPO/MTP ndi 12-core fiber optic patch zingwe ndi 24-core fiber optic patch zingwe, koma m'zaka zaposachedwa zingwe 16-core ndi 32-core fiber optic patch zawonekera.Masiku ano, ma jumpers oposa 100-core multi-core jumpers akutuluka, ndipo kuzindikira kwa polarity kwa ma jumpers ambiri monga MPO/MTP kumakhala kovuta kwambiri.
