Ibhizinisi lobuchwepheshe obuphezulu eligxile ocwaningweni nasekuthuthukisweni kwezokuxhumana kanye nokukhiqizwa kwefiber optical.
Yini isixhumi se-MPO?
Isixhumi se-MPO (I-Multi-fiber Push-On) iyindinganiso yokuxhuma i-multi-fiber exubene kakhulu eyakhiwe yi-NTT yase-Japan futhi kamuva yafanekiswa yi-IEC-61754-7 kanye ne-TIA-604-5. Isixhumi se-MPO, esaziwa nangokuthi i-multi-fiber push-on connector, iyisixhumi se-fiber optic esihlanganisa imicu eminingi yokubona. Ezikhungweni zedatha, uzothola izixhumi ze-MPO ezihlonyiswe ngamafayibha angu-8, 12, noma angu-24. Ngaphezu kwalokho, izixhumi ezinenombolo enkulu yamafiber nazo ziyatholakala, ezivame ukusetshenziswa ezinhlelweni eziphakeme kakhulu. Ukuhlanganiswa kwekhebula le-MPO kuqukethe imicu yokubona, amajakhethi, izikepisi zothuli, nezingxenye zokuxhumanisa izixhumi, ezihlanganisa iziphethu zensimbi, izikhonkwane zomhlahlandlela, nama-ferrules. Izixhumi ze-MPO ziyatholakala ngezinguqulo zabesilisa nabesifazane. Isixhumi sowesilisa sinezikhonkwane ezimbili, kuyilapho isixhumi sowesifazane singenazo izikhonkwane. Isixhumi se-MPO sinokhiye ohlangothini olulodwa lwesixhumi esisetshenziselwa ukunquma indawo yefayibha nokuqinisekisa ukuthi isixhumi singafakwa kuphela ku-adaptha ye-MPO noma imbobo ye-transceiver ngendlela eyodwa. Ukhiye wesixhumi se-MPO esinemicu engu-8, 12, kanye ne-24 sitholakala maphakathi nendlu.
Isikhundla sokuqala sefayibha ye-MPO
Izixhumi ze-MPO zingakwazi ukufaka amafayibha angu-8 kuya kwangu-72, nama-fiber ayi-12 afanayo okuyindlela evamile yokucushwa kwezinhlelo zokusebenza zesikhungo sedatha yebhizinisi njenge-40 Gb kanye ne-100 Gb. Isixhumi ngasinye singowesilisa (ene-ferrules) noma sesifazane (ngaphandle kwama-ferrules) ukuze kuqinisekiswe ukuthi ubuso bokuphela kwefayibha buhlala buqondile ngesikhathi sokukhwelana. Izixhumi ze-MPO futhi zihlanganisa ukhiye phezulu kwesixhumi kanye nechashazi elimhlophe ohlangothini ukukhombisa indawo yesimo 1. Njengoba kuboniswe emfanekisweni ongenhla, ukuma kokhiye nakho kubalulekile uma kuziwa ku-polarity.
Isho ukuthini i-OM ku-MPO fiber?
I-OM1, OM2, OM3, OM4, ne-OM5 amagama aphindaphindayo ezinhlobo ze-multimode fiber. "OM" isifinyezo se-"Optical Multimode". Izinombolo zesi-Arabhu zingaqondwa njengohlelo lokukhululwa kwezizukulwane ezihlukene zezindinganiso ze-multimode fiber. Ihlelwe ngokulandelana kwezikhathi, inombolo enkulu, ngokuhamba kwesikhathi isikhathi sokukhululwa. I-OM1 fiber ingeyokuqala, futhi i-OM5 fiber iyinguqulo yakamuva. Izinhlobo ezihlukene ze-OM zinamadayamitha ayisisekelo ahlukene futhi zihlangabezana namazinga ahlukene okudlulisela. Isibonelo, uma ufuna ukuhlangabezana nezinga lepharamitha lezinga le-100G, udinga ukukhetha okungenani i-OM4 MPO fiber jumper.
I-MPO Fiber Polarity emibili
Izintambo ze-MPO nazo ziza ngezinhlobo ezintathu ezihlukene - Uhlobo A, Uhlobo B, nohlobo C.
Uhlobo A intambo yesiqu se-MPO eqondile enesixhumi esingu-Key Up ngakolunye uhlangothi nesixhumi esingu-Key Down ngakolunye uhlangothi, esivumela i-fiber esendaweni 1 ukuthi iye endaweni engu-1 ngakolunye uhlangothi. Izintambo zohlobo B ziyi-Key Up to Key Up, ngakho-ke ifayibha esesimweni soku-1 iya endaweni engu-12 ngakolunye uhlangothi, i-fiber esendaweni yesi-2 iya endaweni engu-11 ngakolunye uhlangothi, njalonjalo. Izintambo zohlobo C zipheqa amapheya ukuze ifayibha esendaweni 1 iye endaweni yesi-2 ngakolunye uhlangothi, bese ifayibha esendaweni yesi-2 iye endaweni engu-1.
Ungawaxhuma kanjani ama-MPO fibers amabili?
Ukwenza uxhumano lwe-MPO phakathi kwemicu emibili ye-MPO, i-adaptha ye-MPO kufanele isetshenziswe, futhi izinhlobo zesixhumi kufanele zihluke. Lokhu kusho ukuthi ukuxhumana owesilisa nowesifazane kuphela okungafinyelelwa, hhayi ukuxhumana kowesilisa nowesilisa noma owesifazane nowesifazane. Uma izixhumi zesifazane zisetshenziswa kuzo zombili iziphetho ze-adaptha, ukusebenza kuzoba phansi kakhulu ngoba imicu ayikwazi ukuqondisa ngaphandle kwezikhonkwane zesilisa. Ngakolunye uhlangothi, ukusebenzisa izixhumi ezimbili zabesilisa akunakwenzeka futhi kungalimaza izixhumi.
