Cisco oo la jaanqaadi karta 100GBASE-SR4 QSFP28 850nm 100m DOM MPO-12/UPC MMF Module-ka Gudbinta Indhaha, oo la kala jabiyay 4 x 25G-SR oo leh DDM
Sharaxaad
+ Module-ka QSFP-100G-SR4-S ee ku habboon QSFP28 Optical Transceiver waxaa loogu talagalay in lagu isticmaalo 100GBASE Ethernet oo dhex mara ilaa 100m oo ka sarreeya fiber-ka OM4 multimode (MMF) iyadoo la adeegsanayo mowjad dhererkeedu yahay 850nm iyada oo loo marayo isku xiraha MTP/MPO-12. Qalabkan gudbiyaha ah wuxuu u hoggaansamayaa heerka IEEE 802.3bm 100GBASE-SR4 iyo heerka CAUI-4. Hawlaha ogaanshaha dijitaalka ah ayaa sidoo kale laga heli karaa iyada oo loo marayo is-dhexgalka I2C, sida uu qeexay QSFP28 MSA, si loogu oggolaado marin u helidda xuduudaha hawlgalka waqtiga-dhabta ah. Iyada oo leh sifooyinkan, qalabkan gudbiyaha ah ee fudud in la rakibo, ee is-beddelka kulul wuxuu ku habboon yahay in loo isticmaalo codsiyo kala duwan, sida xarumaha xogta, shabakadaha xisaabinta waxqabadka sare leh, codsiyada asaasiga ah ee ganacsiga iyo lakabka qaybinta.

Sharaxa Guud
OP-QSFP28-01 waxaa loogu talagalay in lagu isticmaalo 100 Gigabit ilbiriqsi kasta iyada oo loo marayo fiber-ka qaabka badan.
Waxay u hoggaansamaan QSFP28 MSA iyo IEEE 802.3bm. Qaybta gudbiyaha indhaha ee gudbiyaha waxay ka kooban tahay taxane 4-channel VCSEL (Vertical Cavity Surface Emission Laser) ah, kayd gelinta 4-channel ah iyo darawal laysar ah, kormeerayaasha ogaanshaha, baloogyada xakamaynta iyo eexda. Xakamaynta module-ka, is-dhexgalka xakamaynta wuxuu ka kooban yahay is-dhexgal laba-xagal ah oo saacad iyo calaamado xog ah. Kormeerayaasha ogaanshaha ee
Eexda VCSEL, heerkulka module-ka, awoodda iftiinka ee la gudbiyo, awoodda iftiinka ee la helay iyo danabka sahayda ayaa la hirgeliyay natiijooyinkana waxaa laga heli karaa is-dhexgalka TWS. Digniinta iyo heerarka digniinta ayaa loo dejiyay sifooyinka la kormeeray. Calamada waa la dejiyaa oo hakad ayaa la sameeyaa marka
sifooyinka ayaa ka baxsan xadka. Calamada ayaa sidoo kale la dejiyaa waxaana la sameeyaa hakad marka la waayo calaamadda gelinta
(LOS) iyo xaaladaha cilladaha gudbiyaha. Dhammaan calamada waa la xiray waxayna sii ahaan doonaan kuwo deggan xitaa haddii xaaladda bilaabeysa qabsashada ay baaba'do oo hawlgalku dib u bilaabmo. Dhammaan carqaladaha waa la qarin karaa oo calamada waa la dib u dejin karaa iyadoo la akhrinayo diiwaanka calanka ee ku habboon. Wax soo saarka indhaha ayaa libdhi doona haddii calaamadda gelinta ay lunto haddii aan la joojin. Ogaanshaha cilladaha ama joojinta kanaalka iyada oo loo marayo is-dhexgalka TWS ayaa joojin doonta kanaalka. Xaaladda, digniinta/digniinta iyo macluumaadka cilladaha waxaa laga heli karaa is-dhexgalka TWS.
Qaybta qaataha indhaha ee gudbiyaha waxaa ku jira taxane sawir-qaade PIN ah oo 4-kanaal ah, taxane TIA oo 4-kanaal ah, kayd wax soo saar oo 4 kanaal ah, kormeerayaal ogaansho, iyo xannibaado xakameyn iyo eex ah. Kormeerayaasha ogaanshaha ee awoodda gelinta indhaha ayaa la hirgeliyaa natiijooyinkana waxaa laga heli karaa is-dhexgalka TWS. Digniinta iyo heerarka digniinta ayaa loo dejiyay sifooyinka la kormeeray. Calanka waa la dejiyaa oo carqalad ayaa la sameeyaa marka sifooyinka ay ka baxsan yihiin xuduudaha. Calanka sidoo kale waa la dejiyaa oo carqalad ayaa la sameeyaa marka lumiyo calaamadda gelinta indhaha (LOS). Dhammaan calamadaha waa la xiraa waxayna sii ahaan doonaan kuwo deggan xitaa haddii xaaladda bilaabaysa calanku ay nadiifiso oo hawlgalku dib u bilaabmo. Dhammaan carqaladaha waa la qarin karaa oo calamadaha waa la dib u dejin karaa marka la akhriyo diiwaanka calanka ee ku habboon. Wax soo saarka korontada ayaa la qaboojin doonaa haddii lumiyo calaamadda gelinta (haddii aan la curyaamin) iyo joojinta kanaalka iyada oo loo marayo is-dhexgalka TWS. Macluumaadka xaaladda iyo digniinta/digniinta waxaa laga heli karaa is-dhexgalka TWS.
