Incazelo:

I-JHA-Q28C20 iyimojula ye-transceiver eyenzelwe u-20km optical communication applications. Idizayini ithobelana ne-100GbASE-LR4 ye-IEEE 802.3-2012 Isigaba somthetho 88 esijwayelekile se-IEEE 802.3bm CAUI-4 chip ukuze kumojulwe indinganiso kagesi ye-ITU-T G.959.1-2012-02 . I-module iguqula iziteshi ze-4 zokufaka (ch) ze-25.78 Gbps kuya ku-27.95Gbps idatha kagesi ku-4 imizila yezimpawu ze-optical, futhi iziphindaphinda zibe isiteshi esisodwa se-100Gb / s yokudlulisa optical. Ngokuphambene, ohlangothini lomamukeli, imojula i-optically de-multiplexes okokufaka kwe-100Gb/s ibe amasignali emizila emi-4, futhi iwaguqulele emigwaqweni emi-4 ekhipha idatha kagesi.

Amaza amaphakathi emizila emi-4 ngu-1296 nm, 1300 nm, 1305 nm kanye no-1309 nm. Iqukethe isixhumi se-LC esiyi-duplex yesixhumi esibonakalayo esibonakalayo nesixhumi samaphini angama-38 esixhumi esibonakalayo sikagesi. Ukuze kuncishiswe ukuhlakazeka kokubona ohlelweni lokudonsa isikhathi eside, i-fiber yemodi eyodwa (SMF) kufanele isetshenziswe kule mojula.

Umkhiqizo uklanywe nge-form factor, uxhumano lwe-optical/electric kanye ne-digital diagnostic interface ngokuvumelana ne-QSFP28 Multi-Source Agreement (MSA). Iklanyelwe ukuhlangabezana nezimo zokusebenza zangaphandle ezinzima kakhulu ezihlanganisa izinga lokushisa, umswakama kanye nokuphazanyiswa kwe-EMI.

Imojula isebenza kugesi owodwa we-+3.3V kanye namasiginali okulawula umhlaba wonke we-LVCMOS/LVTTL njengeModule Present, Setha Kabusha, Ukuphazamisa kanye Nemodi Yamandla Aphansi ayatholakala namamojula. I-serial interface enezintambo ezi-2 iyatholakala ukuze ithumele futhi yamukele amasiginali okulawula ayinkimbinkimbi kanye nokuthola ulwazi lokuxilonga lwedijithali. Iziteshi ngazinye zingasingathwa futhi iziteshi ezingasetshenzisiwe zingavalwa ukuze umklamo ube nezimo eziguquguqukayo.

I-JHA-Q28C20 yakhelwe nge-form factor, uxhumano lwe-optical/electric kanye nesixhumi esibonakalayo sokuxilonga esidijithali ngokweSivumelwano se-QSFP28 Multi-Source Agreement (MSA). Iklanyelwe ukuhlangabezana nezimo zokusebenza zangaphandle ezinzima kakhulu ezihlanganisa izinga lokushisa, umswakama kanye nokuphazanyiswa kwe-EMI. Imojula inikeza ukusebenza okuphezulu kakhulu nokuhlanganiswa kwesici, okufinyeleleka nge-serial interface enezintambo ezimbili.

Umsebenzi wokuqapha ukuxilonga kwedijithali uyatholakala kuwo wonke ama-QSFP28 LR4. I-serial interface enezintambo ezi-2 inikeza umsebenzisi ukuthi axhumane nemojuli. Ukwakheka kwenkumbulo kukhonjiswa ngokugeleza. Isikhala senkumbulo sihlelwe saba ngaphansi, ikhasi elilodwa, indawo yekheli engamabhayithi angu-128 namakhasi amaningi esikhala samakheli aphezulu. Lesi sakhiwo sivumela ukufinyelela okufika ngesikhathi kumakheli ekhasini elingezansi, elifana namafulegi aphazamisayo nabaqaphi. Isikhathi esincane esibalulekile esifakiwe, esifana nolwazi lwe-serial ID namasethingi e-threshold, ayatholakala nomsebenzi Wokukhetha Ikhasi. Ikheli lesixhumi esibonakalayo elisetshenzisiwe lithi A0xh futhi lisetshenziselwa kakhulu idatha ebalulekile yesikhathi njengokuphatha ukuphazamiseka ukuze kunikwe amandla ukufundwa kanye nje kwayo yonke idatha ehlobene nesimo sokuphazamiseka. Ngemva kokuphazamiseka, i-IntL isigonyelwe, umsingathi angafunda inkundla yefulegi ukuze anqume isiteshi esithintekile kanye nohlobo lwefulegi.
