    Ukukhuluma ngalezo zinto mayelana namamojula we-SFP optical

    Isikhathi sokuthumela: Sep-30-2019

    Amamojula we-SFP optical amamojula amancane, ashintshashintshayo ashintshashintshayo ashintshashintshayo. Asetshenziswa kakhulu embonini yezokuxhumana. Kunezinhlobo eziningi zamamojula we-SFP optical, njenge-BIDI-SFP, SFP, CWDM SFP, DWDM SFP, kanye ne-SFP+ optical modules. Ngaphezu kwalokho, ngohlobo olufanayo lwe-XFP, i-X2, ne-XENPAK amamojula optical, i-module ye-SFP optical ayikwazi ukuxhumeka ngokuqondile kuyo kuphela, kodwa futhi inezindleko eziphansi. Lapha sikhuluma kafushane ngeminye imiqondo eyisisekelo ye-SFP optical modules, amathiphu, izindlela zokufaka kanye nentengo yamamojula omkhiqizo ahambisanayo ajwayelekile.

    Okokuqala,Uhlolojikelele lwemojuli ye-SFP optical

    1.Incazelo

    Imojula ye-SFP optical ipakishwe kuphakheji elincane elishintshashintshayo elishisayo. Isivinini samanje esiphezulu yi-10G futhi isixhumi esibonakalayo se-LC siphezulu. Isifinyezo se-SFP sithi Small Form-factor Pluggable, esingaqondwa kalula njengenguqulo ethuthukisiwe ye-GBIC. Imojula ye-SFP ye-optical iwuhhafu wosayizi we-GBIC optical module, futhi ingacushwa ngenani lamachweba angaphezu kokuphindwe kabili kuphaneli efanayo.

    2.Ukwakheka

    I-SFP optical module iqukethe i-laser, ibhodi lesifunda IC kanye nezingxenye zangaphandle. Izingxenye zangaphandle zifaka indlu, ilungu elivulayo, i-snap, isisekelo, iringi yokudonsa, ipulaki yerabha, kanye ne-PCBA. Umbala weringi yokudonsa ungakusiza ukuthi ubone uhlobo lwepharamitha yemojuli.

    3.Ukuthuthukiswa kwamamojula we-SFP optical

    Kumojula ye-optical, i-GBIC ne-SFF kancane kancane ithathelwa indawo ngamamojula we-SFP optical ngokuthuthukiswa okusheshayo kwenethiwekhi. Ihamba ibheke ku-miniaturization kanye nokuxhuma okushisayo. Imojula ye-SFP ye-optical izuza njengefa isici sokuxhuma esishisayo se-GBIC futhi idonsa ezinhlelweni ze-SFF miniaturization. Ukusetshenziswa kwesihloko se-LC kukhulisa kakhulu ukuminyana kwechweba lamadivayisi enethiwekhi, kuvumelana nokuthuthukiswa okusheshayo kwenethiwekhi, futhi kuthole isicelo esibanzi kakhulu. Nakuba kuye kwavela imikhiqizo eminingi ye-high-tech kanye nentsha ye-optical module, amamojula we-SFP optical azoqhubeka ekhona isikhathi eside. Ngemuva kwe-SFP, ukuthuthukiswa kwamamojula optical ikakhulukazi ekuthuthukisweni kwesivinini esiphezulu, futhi manje i-10G, 40G, 100G kanye namanye amamojula optical avele.

    Okwesibili, amathiphu we-SFP optical module

    Uma imojula isebenza ngendlela engafanele ngesikhathi sokusetshenziswa, izobangela kalula ukuthi imojuli ye-optical ihluleke. Kulokhu, ungakhathazeki, hlola ngokucophelela futhi uhlaziye izizathu ezithile. Ngokuvamile, kunezinhlobo ezimbili eziyinhloko zokwehluleka kwemojula ye-optical, okungukuthi, ukwehluleka kokuphela kokudlulisela kanye nokwehluleka kokuphela kokwamukela. Izizathu ezivame kakhulu yilezi ezilandelayo:

    1. Ubuso bokugcina besixhumi se-fiber optic esisetshenzisiwe bungcolile, okubangela ukungcoliswa kwesibili kwe-optical module optical port;

    2. I-port optical ye-optical module ibonakala endaweni ezungezile, futhi uthuli lungena futhi lubangele ukungcola;

    3. Sebenzisa izixhumi ze-fiber optic ezingaphansi, njll.

    Ngakho-ke, qaphela ukuhlanza nokuvikelwa kwe-module optical ngesikhathi sokusetshenziswa okujwayelekile. Ngemuva kokusetshenziswa, kunconywa ukuxhuma ipulaki yothuli. Ngenxa yokuthi oxhumana nabo bemojuli yokubona abahlanzekile, kungenzeka kuthinte ikhwalithi yesiginali, okungabangela izinkinga zomugqa namaphutha amancane.

    Okwesithathu, izinyathelo zokuphepha zokufakwa kwe-SFP optical module

    1.Phenya imojula ye-SFP ye-optical phezulu naphansi phezulu, jam i-latch ephezulu, bese ucindezela i-SFP optical module nhlangothi zombili. Phusha imojula ye-SFP ku-slot ye-SFP kuze kube yilapho imojula ye-SFP isondelene ne-slot. Imithombo engaphezulu nangaphansi kwemojuli ibamba i-SFP slot)

    2.Gqoka ibhande lesihlakala elivimbela i-ESD uma ufaka noma ukhipha imojuli yokubona ye-SFP.

    3.Uma i-SFP optical module ingafakwanga ngokuqondile noma ingasuswanga, izingxenye ze-elekthronikhi ku-SFP optical module noma i-SFP slot zingaphulwa nge-electrostatically futhi idivayisi ingase yonakaliswe.

    4.Hambisa i-SFP optical module endaweni evundlile ukuze ususe ubudlelwano obuhleliwe phakathi kwentwasahlobo ne-slot ye-SFP. Khipha ngenkani imojula ye-SFP optical bese ulimaza iziqeshana entwasahlobo noma slot.

    Amamojula we-Optical nawo athola ukunakwa okwengeziwe embonini yezokuxhumana. Amamojula we-SFP optical yiwo aziwa kakhulu kumojula. Okungenhla kufingqa ulwazi lwamamojula we-SFP optical kusuka ezicini ezimbalwa, futhi uthemba ukuletha usizo lwakho lwangempela.
