40KM 40G QSFP + Optical Transceiver Module
O leHUAQ40Eo se transceiver module ua fuafuaina mo 40Km opitika talosaga fesootaiga.O le mamanu e ogatasi ma le 40GBASE-ER4 o le tulaga IEEE P802.3ba.O le module e faʻaliliuina 4 inputs channels(ch) o 10Gb / s faʻamatalaga eletise i le 4 CWDM faailoilo mataʻutia, ma faʻateleina i latou i totonu o se auala e tasi mo le 40Gb / s faʻasalalauga faʻapitoa.I le isi itu, i luga o le itu e taliaina, o le module optically de-multiplexes se 40Gb / s faʻaogaina i le 4 CWDM alavai faailoilo, ma liliu i latou 4 alalaupapa faʻamatalaga eletise.
O galu ogatotonu ole laina ole 4 CWDM ole 1271, 1291, 1311 ma le 1331 nm e avea ma sui o le CWDM wavelength grid faʻamatalaina ile ITU-T G694.2.O loʻo i ai se fesoʻotaʻiga LC faʻalua mo le faʻaogaina o mata ma se fesoʻotaʻiga 38-pin mo le faʻaogaina eletise.Ina ia faʻaitiitia le faʻasalalau faʻapitoa i totonu o le faiga umi, e tatau ona faʻaogaina le fiber-mode fiber (SMF) i lenei module.
O le oloa ua mamanuina ma foliga faʻapitoa, fesoʻotaʻiga mata / eletise ma faʻamatalaga faʻainisinia numera e tusa ai ma le QSFP Multi-Source Agreement (MSA).Ua mamanuina ina ia fetaui ma tulaga sili ona faigata i fafo e aofia ai le vevela, susu ma le EMIinterference.
O lo'o fa'agaoioia le module mai le tasi + 3.3V power supply ma LVCMOS/LVTTL fa'atonuga fa'alelalolagi e pei ole Module Present, Reset, Interrupt and Low Power Mode o lo'o avanoa fa'atasi ma modules.O lo'o avanoa le feso'ota'iga fa'asologa e 2-uaea e lafo ma maua ai fa'ailo fa'atonutonu lavelave ma maua mai fa'amatalaga fa'afuainumera.E mafai ona fa'afeso'ota'i ala ta'ito'atasi ma e mafai ona tapuni laina e le'i fa'aaogaina mo le maualuga o le fa'aogaina o le mamanu.
O lenei oloa fa'aliliuina le 4-channel 10Gb / s fa'amaumauga eletise i totonu o fa'ailoga opitika CWDM (malamalama), e ala i le fa'auluina o le 4-wavelength Distributed Feedback Laser (DFB) array.O le malamalama o loʻo tuʻufaʻatasia e vaega MUX o se faʻamatalaga 40Gb / s, faʻasalalau mai le module transmitter mai le SMF.E talia e le module receiver le 40Gb/s CWDM optical signal input, ma de-multiplexed i 4 tagata taʻitoʻatasi 10Gb/s auala ma eseese galu umi.O moli uumi ta'itasi e aoina mai e se fa'aata avalanche discrete (APD), ona fa'auluina lea e fai ma fa'amaumauga eletise pe a uma ona fa'ateleina muamua e le TIA ona fa'asolo lea i le pou fa'apipi'i.
O leHUAQ40Eua mamanuina ma foliga faʻailoga, fesoʻotaʻiga opitika / eletise ma faʻamatalaga faʻainisinia numera e tusa ai ma le QSFP Multi-Source Agreement (MSA).Ua mamanuina ina ia ausia tulaga sili ona faigata i fafo e aofia ai le vevela, susu ma le faʻalavelave EMI.O le module e ofoina atu le maualuga tele o galuega ma le tuʻufaʻatasia faʻapitoa, e mafai ona maua e ala i se fesoʻotaʻiga laina lua-uaea.
