I-SFP-ETRx-4
10/100/1000 BASE-T I-Copper SFP Transceiver
I-SFP-ETRx-4
Incazelo Yomkhiqizo
I-ER4 iyimojula ye-transceiver eyenzelwe izinhlelo zokusebenza zokuxhumana ze-40km optical. Idizayini ithobelana ne-40GBASE-ER4 yezinga le-IEEE P802.3ba. I-module iguqula iziteshi ze-4 zokufakwayo (ch) zedatha kagesi ye-10Gb / s kumasignali we-4 CWDM optical, futhi iphindaphinda ibe isiteshi esisodwa se-40Gb / s yokudlulisa optical. Ngokuphambene, ohlangothini lomamukeli, imojula i-optically demultiplexes okokufaka kwe-40Gb/s ibe amasignali amashaneli angu-4 CWDM, futhi iwaguqulele kudatha kagesi ephumayo yesiteshi esingu-4.
Amaza amaphakathi eziteshi ezi-4 ze-CWDM angu-1271, 1291, 1311 kanye no-1331 nm njengamalungu egridi ye-wavelength ye-CWDM echazwe ku-ITU-T G694.2. Iqukethe aI-adaptha ye-LC duplexokwesixhumi esibonakalayo esibonakalayo namaphini angu-38i-adapthaokwesixhumi 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-QSFP 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-TQP10 yakhelwe nge-form factor, uxhumano lwe-optical/electrical kanye nesixhumi esibonakalayo sokuxilonga esidijithali ngokweSivumelwano se-QSFP 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.

I-Diagnostic Monitoring Interface
Umsebenzi wokuqapha ukuxilonga kwedijithali uyatholakala kuwo wonke ama-QSFP+ ER4. 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, njengokuthi Ukuphazamisa
Amafulegi kanye 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.
