I-polarity ye-LC / SC kunye ne-MPO / MTP fibers

I-duplex fiber kunye ne-polarity
Ekusetyenzisweni kwe-10G i-fiber ye-Optical, iifayili ezimbini ze-optical zisetyenziselwa ukuqonda ukuhanjiswa kwedatha ezimbini.Esinye isiphelo sefiber optical nganye sidityaniswe kwi-transmitter kwaye esinye isiphelo siqhagamshelwe kumamkeli.Zombini ziyimfuneko.Siwabiza ngokuba yi-duplex optical fiber, okanye i-duplex optical fiber.

Ngokuhambelanayo, ukuba kukho i-duplex, kukho i-simplex.I-Simplex ibhekisela ekudluliseni ulwazi kwicala elinye.Kuzo zombini iziphelo zonxibelelwano, esinye isiphelo sisidluliseli kwaye esinye isiphelo ngumamkeli.Njengompompo wasekhaya, idatha ihamba kwicala elinye kwaye ayiphindi ibuyiselwe umva.(ewe, kukho ukungaqondi kakuhle apha. Enyanisweni, unxibelelwano lwefiber optical luntsokothile kakhulu. I-Optical fiber inokudluliselwa kumacala amabini. Sifuna nje ukwenza lula ukuqonda.)

Ukubuyela kwi-duplex fiber, i-TX (b) kufuneka ihlale iqhagamshelwe kwi-RX (a) kungakhathaliseki ukuba zingaphi iipaneli, ii-adapters okanye i-optical cable sections zikhona kwinethiwekhi.Ukuba i-polarity ehambelanayo ayibonwa, idatha ayiyi kuhanjiswa.

Ukuze kugcinwe i-polarity echanekileyo, umgangatho we-tia-568-c ucebisa iskimu sokuwela i-AB polarity ye-duplex jumper.


I-MPO/MTP ifayibha polarity
Ubungakanani be-MPO / MTP isinxibelelanisi siyafana neso sidibanisi se-SC, kodwa sinokuthatha i-12 / 24 / 16 / 32 i-fibers optical.Ke ngoko, i-MPO inokonga kakhulu indawo yeentambo zekhabhathi.

Iindlela ezintathu ze-polarity ezichazwe kumgangatho we-TIA568 zibizwa ngokuba yindlela A, indlela ye-B kunye nendlela C ngokulandelanayo.Ukuze kuhlangatyezwane nomgangatho we-TIA568, iintambo ze-MPO/MTP ze-backbone optical nazo zahlulwe zibe yi-, ukunqumla ngokupheleleyo kunye nokuwela isibini, oko kukuthi, uhlobo A (isitshixo phezulu - isitshixo sehla nge-), uhlobo B (isitshixo phezulu - isitshixo phezulu / isitshixo phantsi isitshixo phantsi ugqibezele ukuwela) kwaye uchwetheze C (isitshixo phezulu - isitshixo ezantsi ukuwela iperi).
Njengoko kubonisiwe kumfanekiso ongezantsi:

Iintambo ezisetyenziswa ngoku eziqhelekileyo ze-MPO/MTP ziyi-12-core fibre optic patch cords kunye ne-24-core fibre optic patch cords, kodwa kwiminyaka yakutshanje i-16-core kunye ne-32-core fiber optic patch cords ziye zavela.Kule mihla, ngaphezu kwe-100-core multi-core jumpers iyaphuma, kwaye ukuchongwa kwe-polarity yee-multi-core jumpers ezifana ne-MPO/MTP iba ​​yinto ebaluleke kakhulu.
