Cisco Wanaagsan 100GBASE-SR4 QSFP28 850nm 100m DOM MPO-12/UPC MMF Module Transceiver Optical, Jebinta ilaa 4 x 25G-SR oo leh DDM
Sharaxaada
+ Cisco QSFP-100G-SR4-S ku habboon QSFP28 Module Transceiver Optical waxaa loogu talagalay in lagu isticmaalo 100GBASE Ethernet wax soo saarka ilaa 100m oo ka sarreeya OM4 fiber multimode (MMF) iyadoo la adeegsanayo mowjadaha dhererka 850nm iyada oo loo marayo isku xirka MTP/MPO-12. Transceiver Tani waxay u hogaansantaa IEEE 802.3bm 100GBASE-SR4 iyo CAUI-4 heerka. Hawlaha ogaanshaha dhijitaalka ah ayaa sidoo kale laga heli karaa iyada oo loo sii marayo interface-ka I2C, sida lagu qeexay QSFP28 MSA, si loogu oggolaado gelitaanka cabbirrada hawlgalka ee waqtiga-dhabta ah. Astaamahan, tan sahlan in la rakibo, gudbiyaha kulul ee la isku beddeli karo ayaa ku habboon in loo isticmaalo codsiyo kala duwan, sida xarumaha xogta, shabakadaha xisaabinta waxqabadka sare, xudunta ganacsiga iyo codsiyada lakabka qaybinta.

Sharaxaada Guud
OP-QSFP28-01 waxaa loogu talagalay in lagu isticmaalo 100 Gigabit isku xirka ilbiriqsi kasta oo ka badan fiber qaab badan.
Waxay u hoggaansamaan QSFP28 MSA iyo IEEE 802.3bm. Qaybta gudbiyaha indhaha ee gudbiyaha waxa ku jira 4-channel VCSEL (Vertical Cavity Surface Emitting Laser) array, 4-kanaal wax gelin ah iyo darawal laser, kormeerayaasha ogaanshaha, xakamaynta iyo xannibaadaha eexda. Xakamaynta moduleka, kontoroolka kontoroolka waxa uu ka kooban yahay laba Wire Serial interface oo saacad iyo calaamado xog ah. Kormeerayaasha ogaanshaha ee
Eexda VCSEL, heerkulka moduleka, awoodda indhaha ee la kala qaado, la helay koronta indhaha iyo korantada sahayda ayaa la hirgeliyay natiijadana waxaa laga heli karaa isdhexgalka TWS. Qaylo dhaanta iyo heerarka digniinta ayaa loo dejiyay sifada la kormeero. Calamada waa la dejiyaa oo hakad baa la sameeyaa marka
sifooyinka ayaa ka baxsan marinnada. Calamada sidoo kale waa la dejiyay oo hakad loo sameeyaa si ay u lumiyaan calaamada wax gelinta
(LOS) iyo xaaladaha cilladaha gudbiyaha. Dhammaan calamada way xidhan yihiin wayna sii xidhnaan doonaan xataa haddii ay xaaladdu furto xadhiga oo ay dib u bilaabato. Dhammaan carqaladaha waa la qarin karaa oo calanka dib ayaa loo dejin karaa iyadoo la akhrinayo diiwaanka calanka ee habboon. Wax-soo-saarka indho-ku-soo-saarka waxa uu lumin doonaa luminta signal-ka-gelinta ilaa uu naafo yahay mooyee. Cilladda ogaanshaha ama deminta kanaalka iyada oo loo marayo is-dhexgalka TWS ayaa joojin doona kanaalka. Xaaladda, qaylo-dhaanta/ digniinta iyo macluumaadka khaladka ah ayaa laga heli karaa is-dhexgalka TWS.
Qaybta qaataha indhaha ee transceiver waxa ku jira 4-channel PIN photodiode array, 4-channel TIA array, 4 channels soo saarista kaydiyaha, kormeerayaasha ogaanshaha, iyo xakamaynta iyo xannibaadaha eexda. Kormeerayaasha ogaanshaha ee awoodda gelinta indhaha ayaa la hirgeliyay natiijadana waxaa laga heli karaa interface-ka TWS. Qaylo dhaanta iyo heerarka digniinta ayaa loo dejiyay sifada la kormeero. Calamada waa la dejiyaa oo hakad baa la sameeyaa marka sifooyinku ka baxsan yihiin xadka. Calamada sidoo kale waa la dejiyay oo hakad baa loo abuuraa luminta calaamada wax gelinta indhaha (LOS). Dhammaan calamada way xidhan yihiin wayna sii xidhnaan doonaan xataa haddii xaalada calamada bilawday ay nadiifiso oo ay dib u bilaabato. Dhammaan carqaladaha waa la dabooli karaa oo calanka dib ayaa loo dajin karaa marka la akhriyo diiwaanka calanka ee habboon. Wax-soo-saarka korontadu wuxuu ku lumin doonaa lumitaanka calaamadda wax-gelinta (haddii aysan squelch naafo ahayn) iyo ka-joojinta kanaalka iyada oo loo marayo interface TWS. Xaalada iyo digniinta/macluumaadka digniinta ayaa laga heli karaa isdhexgalka TWS.
