40KM 40G QSFP+ Optical Transceiver Module
II-HUAQ40Eiyimojula ye-transceiver eyenzelwe izinhlelo zokusebenza zokuxhumana ze-40Km.Idizayini ithobelana ne-40GBASE-ER4 yezinga le-IEEE P802.3ba.Imojula iguqula iziteshi zokufakwayo ezingu-4 (ch) zedatha kagesi ye-10Gb/s kumasiginali we-4 CWDM optical, futhi iphindaphindeka ibe isiteshi esisodwa se-40Gb/s yokudlulisela optical.Ngokuhlehlayo, ohlangothini lomamukeli, imojula i-optically de-multiplexes okokufaka kwe-40Gb/s kumasignali amashaneli angu-4 CWDM, futhi iwaguqulela 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 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-QSFP Multi-Source Agreement (MSA).Iklanyelwe ukuhlangabezana nezimo zokusebenza zangaphandle ezinzima kakhulu ezihlanganisa izinga lokushisa, umswakama kanye nokuphazamiseka 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.
Lo mkhiqizo uguqula idatha yokufaka kagesi engu-4-channel 10Gb/s ibe amasignali okubonayo e-CWDM (ukukhanya), ngohlelo oluqhutshwa yi-4-wavelength Distributed Feedback Laser (DFB).Ukukhanya kuhlanganiswe izingxenye ze-MUX njengedatha ye-40Gb/s, esakaza kumojula yokudlulisela kusuka ku-SMF.Imojuli yomamukeli yamukela okokufaka kwezimpawu ze-40Gb/s CWDM ze-optical, futhi i-de-multiplexes ibe amashaneli angu-4 angawodwana angu-10Gb/s anobude obuhlukile beza.Ukukhanya kwe-wavelength ngakunye kuqoqwa i-avalanche photodiode (APD), bese ikhishwa njengedatha kagesi ngemva kokukhuliswa kuqala nge-TIA bese kuba yi-post amplifier.
II-HUAQ40Eyakhelwe nge-form factor, uxhumano lwe-optical/electric kanye nesixhumi esibonakalayo sokuxilonga idijithali 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.
Izici 4 CWDM imizila idizayini MUX/DEMUX Kufika ku-11.2Gbps ngomkhawulokudonsa wesiteshi ngasinye Umkhawulokudonsa ohlanganisiwe > 40Gbps Isixhumi se-Duplex LC Ihambisana ne-40G Ethernet IEEE802.3ba kanye ne-40GBASE-ER4 Standard I-QSFP MSA iyahambisana Ifinyelela ku-40km transmission Ihambisana nezilinganiso zedatha ye-QDR/DDR Infiniband I-single +3.3V yamandla esebenzayo Imisebenzi yokuxilonga yedijithali eyakhelwe ngaphakathi Izinga lokushisa ngu-0°Cto 70°C I-RoHS Iyahambisana
