I-KCO QSFP+ 40G ER4 40Gb/s QSFP+ SMF 1310 40km Transceiver
KUYINI i-QSFP+ 40G ER4?
+ II-QSFP+ 40G ER4 iyahambisana. Imojula ye-transceiver ye-QSFP+ engu-40G ifakwe izixhumi ze-duplex ze-LC, ezifinyelela isixhumanisi esifinyelela ku-10km ngaphezulu kwe-OS2 single-mode fiber (SMF).
+ Le transceiver ye-fiber optical ye-40G iza nesixhumi se-QSFP+ esineziteshi ezine eziqondiswe kabili, esivumela i-bandwidth engu-40 Gbps ngesiteshi ngasinye esiphethe izinga ledatha le-10 Gbps.
+ Umsebenzi we-DOM/DDM (ukuqapha ukuxilongwa kwedijithali) usekelwa ku-transceiver ye-fiber optic engu-40G ukuze kufezwe ukuqapha kwamapharamitha okusebenza ngesikhathi sangempela.
+ Senze i-module ye-40GBASE-ER4 QSFP+ iyahambisana ne-QSFP+ MSA kanye ne-IEEE 802.3ba 40GBASE-ER4 specifications. Ngaphandle kwalokho, i-quad small form-factor pluggable (QSFP) ER4 optic ihlolwe kumadivayisi e-host ukuqinisekisa ukuhambisana okugcwele nemishini ye-Huawei, njenge-data center switches, ama-enterprise routers, kanye namakhadi e-server network interface (NICs). I-module ye-40G SFP yomuntu wesithathu iyindlela efanelekile yokufaka esikhundleni se-Huawei QSFP-40G-ER4 QSFP+ 40G transceiver ngentengo engabizi, enikeza isisombululo esihambisanayo esingabizi kakhulu sokuxhumeka kwe-40G okusebenzayo okuphezulu.
+ Ama-optics e-QSFP+ 40G ER4 anakekela ukuxhumeka kwe-fiber optical okungu-40 Gigabit Ethernet (40GbE), alungele izinhlelo zokusebenza ezisebenza kahle kakhulu nezikude kumanethiwekhi okuhamba ibanga elide, amanethiwekhi ekhampasi, amanethiwekhi e-metro, njll.

Incazelo Ejwayelekile
I-OP-QSFP+-LER yakhelwe ukusebenza ngesistimu yefayibha yemodi eyodwa isebenzisa isiteshi se-4X10 CWDM kubhendi engu-1310 futhi ixhumanisa amakhilomitha afinyelela ku-40. Imojula iguqula isiteshi sokufaka esingu-4 sedatha kagesi engu-10Gb/s sibe amasignali okubona angu-4 e-CWDM, bese iwahlanganisa abe yisiteshi esisodwa sokudlulisa okubonakalayo okungu-40Gb/s. Ngokuphambene nalokho, ohlangothini lokwamukela, imojula isusa ama-multiplex ngokubonakalayo okokufaka okungu-40Gb/s kube amasignali okubona angu-4 e-CWDM, bese iwaguqula abe idatha kagesi yokuphuma kweziteshi ezingu-4.
Ama-wavelength aphakathi eziteshi ezine ze-CWDM angama-1271, 1291, 1311 kanye no-1331 nm. Aqukethe isixhumi se-LC esiphindwe kabili se-optical interface kanye nesixhumi esingu-38-pin se-electrical interface. I-fiber yemodi eyodwa (i-SMF) isetshenziswa kule module. Lo mkhiqizo uguqula idatha yokufaka kagesi yeziteshi ezine ye-10Gb/s ibe yizimpawu ezibonakalayo ze-CWDM (ukukhanya), nge-array ye-Distributed Feedback Laser (DFB) enamagagasi amane. Ama-wavelength amane aphindaphindwa abe idatha eyodwa ye-40Gb/s, esakazeka ngaphandle kwemojuli yokudlulisa nge-SMF. Imojuli yokwamukela yamukela ukufakwa kwezimpawu ezibonakalayo ze-40Gb/s, bese isusa ama-multiplex abe yiziteshi ezine ze-CWDM 10Gb/s. Ukukhanya ngakunye kwamagagasi kuqoqwa yi-diode yesithombe ehlukile, bese kukhishwa njengedatha kagesi ngemva kokukhuliswa yi-TIA.
Lo mkhiqizo wenzelwe i-form factor, uxhumano lwe-optical/electric kanye ne-digital diagnostic interface ngokwe-QSFP+ Multi-Source Agreement (MSA) futhi uhambisana ne-40G QSFP+ LR4 ye-IEEE 802.3ba.
