I-voltage yokudonsela phezulu kufanele ibe phakathi kuka-2.0V ukuya ku-Vcc + 0.3VA okukhiphayo okuphezulu kubonisa iphutha lesidluliseli elibangelwa amandla amanje okuchema kwe-TX noma amandla okukhiphayo e-TX edlula imingcele ye-alamu esethiwe. Okukhiphayo okuphansi kubonisa ukusebenza okuvamile. Esimeni esiphansi, okukhiphayo kudonselwa ku-<0.8V.
- Okukhipha i-laser kukhutshaziwe ku-TDIS>2.0V noma ivuliwe, inikwe amandla ku-TDIS<0.8V.
- Kufanele idonswe ngebhodi lokusingatha elingu-4.7kΩ- 10kΩ ku-voltage ephakathi kuka-2.0V no-3.6V. I-MOD_ABS idonsa umugqa uphansi ukuze ibonise ukuthi imojuli ixhunyiwe.
- Ngaphakathi kudonswe phansi nge-SFF-8431 Rev 4.1.
- I-LOS iwukukhipha komqoqi ovulekile. Kufanele idonswe ngo-4.7kΩ – 10kΩ ebhodini lomsingathi ibe ngugesi ophakathi kuka-2.0V no-3.6V. I-Logic 0 ikhombisa ukusebenza okuvamile; i-logic 1 ibonisa ukulahlekelwa kwesignali.
Digital Diagnostic Imisebenzi
Ama-transceivers e-OP-SFP+-ER asekela i-2-wire serial communication protocol njengoba kuchazwe ku-SFP+MSA.
I-serial ID ejwayelekile ye-SFP inikeza ukufinyelela olwazini lokuhlonza oluchaza amandla womdluliseli, ukuxhumana okujwayelekile, umkhiqizi, nolunye ulwazi.
Ukwengeza, ama-transceivers e-SFP + anikeza isikhombimsebenzisi esiyingqayizivele esithuthukisiwe sokuqapha ukuxilonga kwedijithali, okuvumela ukufinyelela kwesikhathi sangempela kumingcele yokusebenza kwedivayisi njengokushisa kwe-transceiver, i-laser bias current, amandla optical adlulisiwe, ithole amandla optical kanye ne-transceiver supply voltage. Iphinde ichaze isistimu eyinkimbinkimbi ye-alamu namafulegi asexwayiso, axwayisa abasebenzisi bokugcina lapho amapharamitha athile okusebenza angaphandle kwebanga elijwayelekile lesethi yefekthri.
I-SFP MSA ichaza imephu yememori yamabhayithi angu-256 ku-EEPROM efinyeleleka ngaphezu kokuxhumana kwe-serial yezintambo ezingu-2 kukheli le-8 bit 1010000X (A0h).Isixhumi esibonakalayo sokuqapha ukuxilonga kwedijithali sisebenzisa ikheli le-8 bit 1010001X (A2h), ngakho-ke imephu yememori ye-serial echazwe ekuqaleni ihlala ingashintshiwe.
Ulwazi olusebenzayo nolokuxilonga luyagadwa futhi lubikwe I-Digital Diagnostics Transceiver Controller (DDTC) ngaphakathi kwe-transceiver, efinyelelwa nge-serial interface enezintambo ezi-2. Uma iphrothokholi ye-serial yenziwa isebenze, isignali yewashi lomkhiqizo (SCL, Mod Def 1) ikhiqizwa umsingathi. Unqenqema oluphozithivu luwashi idatha ku-transceiver ye-SFP kulawo masegimenti e-E2PROM angavikelekile ngokubhala. Unqenqema olunegethivu lwewashi idatha evela ku-transceiver ye-SFP. Isiginali yedatha yomkhiqizo (i-SDA, i-Mod Def 2) inamacala amabili okudlulisa idatha ye-serial. Umsingathi usebenzisa i-SDA ngokuhlanganyela ne-SCL ukumaka ukuqala nesiphetho sokwenziwa kusebenze kwephrothokholi yochungechunge. Izinkumbulo zihlelwa njengochungechunge lwamagama edatha angu-8-bit angabhekwa ngawodwana noma ngokulandelana.
