Moduli ya Transceiver ya 40KM 40G QSFP+ Optical
ItsindaHUAQ40Eni module ya transceiver yagenewe porogaramu z'itumanaho rya optique rya 40Km. Igishushanyo mbonera cyayo gihuye na 40GBASE-ER4 y'ibipimo bya IEEE P802.3ba. Module ihindura imiyoboro 4 y'amakuru y'amashanyarazi ya 10Gb/s ikayishyiramo ibimenyetso 4 bya CWDM, kandi ikayihinduramo umuyoboro umwe wo kohereza amakuru ya optique ya 40Gb/s. Mu buryo bunyuranye, ku ruhande rwa receiver, module ikuraho byinshi mu buryo bwa optique 40Gb/s mu bimenyetso 4 bya CWDM, hanyuma ikayihinduramo amakuru y'amashanyarazi ya 4.
Uburebure bw'uburebure bw'imiyoboro ine ya CWDM ni 1271, 1291, 1311 na 1331 nm nk'ibice bigize grid y'uburebure bwa CWDM ivugwa muri ITU-T G694.2. Irimo umuhuza wa LC wa duplex wo ku murongo wa optique n'umuhuza wa pin 38 wo ku murongo w'amashanyarazi. Kugira ngo ugabanye ikwirakwira ry'urumuri muri sisitemu y'urugendo rurerure, fibre imwe (SMF) igomba gukoreshwa muri iyi module.
Iki gicuruzwa cyakozwe gifite imiterere y’ishusho, umurongo w’amashanyarazi ukoresha optique/electrical hamwe n’uburyo bwo gusuzuma amakuru hakoreshejwe ikoranabuhanga nk’uko biteganywa n’amasezerano ya QSFP Multi-Source (MSA). Cyakozwe kugira ngo gihuze n’imiterere y’imikorere y’inyuma irimo ubushyuhe, ubushuhe n’ingaruka za EMI.
Iyi module ikora ikoresheje amashanyarazi ya +3.3V imwe kandi ibimenyetso bya LVCMOS/LVTTL byo kugenzura isi nka Module Present, Reset, Interrupt na Low Power Mode birahari hamwe na module. Hari uburyo bwo kohereza no kwakira ibimenyetso bigoye byo kugenzura no kubona amakuru ajyanye no gusuzuma amakuru y’ikoranabuhanga. Imiyoboro imwe n’imwe ishobora gukorerwaho ubushakashatsi kandi imiyoboro idakoreshwa ishobora gufungwa kugira ngo imiterere yayo ibe yoroshye cyane.
Iki gicuruzwa gihindura amakuru y’amashanyarazi ya 10Gb/s afite imiyoboro 4 mu bimenyetso bya CWDM (urumuri), hakoreshejwe uburyo bwa 4-wavelength Distributed Feedback Laser (DFB) array. Urumuri ruhuzwa n’ibice bya MUX nk’amakuru ya 40Gb/s, rukava muri module ya transmitter iva muri SMF. Module yakira 40Gb/s CWDM optique signals, hanyuma ikarukuraho mu buryo bwinshi mu miyoboro 4 ya 10Gb/s ifite uburebure butandukanye. Buri rumuri rw’uburebure rukusanywa na diode ya avalanche (APD) ya discrete, hanyuma rugasohoka nk’amakuru y’amashanyarazi nyuma yo kongererwa imbaraga na TIA hanyuma hagakurikiraho post amplifier.
ItsindaHUAQ40EYakozwe ifite imiterere y’imashini, ikoranabuhanga rya optique/electric hamwe n’ikoranabuhanga risuzuma amakuru hakurikijwe amasezerano ya QSFP Multi-Source (MSA). Yakozwe kugira ngo ihuze n’imiterere y’imikorere y’inyuma irimo ubushyuhe, ubushuhe n’ingaruka za EMI. Iyi module itanga imikorere myiza cyane no guhuza imikorere, iboneka binyuze mu buryo bw’imirongo ibiri.
