Inkcazo
+ I-Cisco QSFP-100G-SR4-S Ehambelanayo ne-QSFP28 Imodyuli ye-Optical Transceiver yenzelwe ukusetyenziswa kwi-100GBASE Ethernet throughput ukuya kwi-100m phezu kwe-OM4 i-fiber multimode (MMF) usebenzisa i-wavelength ye-850nm nge-MTP / MPO-12 ikhonkco. Le transceiver ihambelana ne-IEEE 802.3bm 100GBASE-SR4 kunye ne-CAUI-4 eqhelekileyo. Imisebenzi ye-Digital diagnostics iyafumaneka kwakhona nge-interface ye-I2C, njengoko ichazwe yi-QSFP28 MSA, ukuvumela ukufikelela kwiiparamitha zokusebenza kwexesha langempela. Ngezi mpawu, oku kulula ukuyifaka, i-transceiver eshushu eguqukayo ifanelekile ukuba isetyenziswe kwizicelo ezahlukeneyo, njengamaziko edatha, iinethiwekhi zekhompyuter ezisebenza kakhulu, isiseko seshishini kunye nezicelo zomaleko wokusabalalisa.

Inkcazo ngokubanzi
I-OP-QSFP28-01 yenzelwe ukusetyenziswa kwi-100 Gigabit ngesibini ikhonkco kwi-multi mode fiber.
Ziyahambelana ne-QSFP28 MSA kunye ne-IEEE 802.3bm. Inxalenye ye-optical transmitter ye-transceiver idibanisa i-4-channel VCSEL (i-Vertical Cavity Surface Emitting Laser) i-array, i-4-channel input input buffer kunye nomqhubi we-laser, iimonitha zokuxilonga, iibhloko zokulawula kunye ne-bias. Kulawulo lwemodyuli, i-interface yolawulo idibanisa i-Two Wire Serial interface yewotshi kunye neempawu zedatha. Iimonitha zokuxilonga ze
I-VCSEL i-bias, iqondo lokushisa kwimodyuli, amandla ombane athunyelweyo, amandla okukhanya afunyenweyo kunye nombane wokubonelela aphunyeziwe kwaye iziphumo zifumaneka nge-interface ye-TWS. I-alamu kunye ne-alamu kunye nesilumkiso zisekwe kwiimpawu ezibekwe esweni. Iiflegi zisetwa kwaye ziphazamise zenziwe xa i
iimpawu zingaphandle kwemida. Iiflegi nazo zisetiwe kwaye iziphazamiso zenziwe ngenxa yokulahlekelwa ngumqondiso wegalelo
(LOS) kunye neemeko zempazamo zothumelo. Zonke iiflegi zixhonyiwe kwaye ziya kuhlala zicwangcisiwe nokuba imeko yokuqalisa i-latch iyacinywa kwaye umsebenzi uqalise kwakhona. Zonke iziphazamiso zinokugqunywa kwaye iiflegi zisetwa ngokutsha ngokufunda irejista yeflegi efanelekileyo. Imveliso ye-optical iyakucudisa ukulahlekelwa ngumqondiso wongeniso ngaphandle kokuba i-squelch ivaliwe. Ukufunyaniswa kwempazamo okanye ukucinywa kwetshaneli kusetyenziswa ujongano lwe-TWS kuya kuluvala umjelo. Ubume, i-alam/isilumkiso kunye nolwazi lwempazamo luyafumaneka ngojongano lwe-TWS.
Ingxenye ye-optical receiver ye-transceiver ibandakanya i-4-channel PIN photodiode array, i-4-channel TIA array, i-4 channels output buffer, iimonitor zokuxilonga, kunye neebhloko zokulawula kunye ne-bias. Iimonitha zokuxilonga zamandla okufakwa kwamehlo ziyaphunyezwa kwaye iziphumo ziyafumaneka ngojongano lwe-TWS. I-alamu kunye ne-alamu kunye nesilumkiso zisekwe kwiimpawu ezibekwe esweni. Iiflegi zisetiwe kwaye iziphazamiso zenziwe xa iimpawu zingaphandle kwemida. Iiflegi nazo zisetiwe kwaye iziphazamiso zenziwe ngenxa yokulahleka kwesignali ye-optical input (LOS). Zonke iiflegi zifakwe iiflegi kwaye ziya kuhlala zicwangcisiwe nokuba imeko yokuqalisa iflegi iyacinywa kwaye umsebenzi uqalise kwakhona. Zonke iziphazamiso zinokugqunywa kwaye iiflegi zisetwa ngokutsha xa kufundwa irejista yeflegi efanelekileyo. Imveliso yombane iya kucudisa ilahleko yesiginali yegalelo (ngaphandle kokuba i-squelch ivaliwe) kunye nokususwa kwetshaneli ngojongano lwe-TWS. Ubume kunye ne-alam/isilumkiso solwazi ziyafumaneka ngojongano lwe-TWS.
