Inkcazo

+ IFomu encinci iPluggable (SFP)yifomathi yemodyuli yojongano lwenethiwekhi edibeneyo, eshushu-pluggable esetyenziswa kuzo zombini unxibelelwano kunye nedatha yonxibelelwano.

I-SFP interface kwi-hardware yothungelwano yi-slot yemodyuli ye-transceiver yemidiya ethile, njengentambo ye-fiber-optic okanye intambo yobhedu.

+ QSFP, emele iQuad Small-Factor Factor Pluggable,luhlobo lwemodyuli ye-transceiver esetyenziselwa ukuhanjiswa kwedatha ye-high-speed kwi-networking devices, ngokukodwa kumaziko edatha kunye neendawo eziphezulu zokusebenza zekhompyutha.

Yenzelwe ukuxhasa amajelo amaninzi (ngokuqhelekileyo amane) kwaye inokuphatha amaxabiso edatha ukusuka kwi-10 Gbps ukuya kwi-400 Gbps, kuxhomekeke kuhlobo oluthile lwemodyuli.

Inkcazo ngokubanzi

OP-QSFP+-01ziyilelwe ukusetyenziswa kwi-40 yeGigabit ngesekhondi ikhonkco ngaphezulu kwefayibha yemultimode.

Ziyahambelana ne-QSFP + MSA kunye ne-IEEE 802.3ba 40GBASE-SR4.

Inxalenye ye-optical transmitter ye-transceiver idibanisa i-4-channel VCSEL (i-Vertical Cavity

I-Surface Emitting Laser) uluhlu, i-4-channel 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 kwi-VCSEL bias, ubushushu bemodyuli, ukuhanjiswa kwamandla optical,amandla ombane afunyenweyo kunye nombane wobonelelo aphunyeziwe 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 ziphazamiseke ezenziwe ngenxa yokulahlekelwa kwesignali yokufaka (LOS) kunye neemeko zempazamo zokuhambisa. 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 ye-output buffer ye-channel, iimonitha 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.
