10KM 40G QSFP + Optical Tranceiver Module
TheQSFP+ ma transceiver modules adapangidwa kuti azigwiritsidwa ntchito mu 40 Gigabit pa sekondi imodzi pama fiber multimode.Amagwirizana ndi QSFP + MSA ndi IEEE 802.3ba 40GBASE-SR4. Gawo la optical transmitter la transceiver limaphatikizapo 4-channel VCSEL (Vertical Cavity Surface Emitting Laser) gulu, 4-channel input input buffer ndi laser driver, control and bias. midadada.Gawo lolandila kuwala la transceiver limaphatikizapo 4-channel PIN photodiode array, 4-channel TIA array, 4 channel output buffer, control blocks.

40KM 40G QSFP + Optical Transceiver Module
TheChithunzi cha HUAQ40Endi transceiver module yopangidwira 40Km optical communication applications.Mapangidwewo akugwirizana ndi 40GBASE-ER4 ya IEEE P802.3ba muyezo.Gawoli limasintha njira za 4 zolowetsamo (ch) za deta yamagetsi ya 10Gb / s ku zizindikiro za kuwala kwa 4 CWDM, ndikuzichulukitsa mu njira imodzi ya 40Gb / s optical transmission.Mosiyana, kumbali yolandila, module optically de-multiplexes a 40Gb / s kulowetsa muzitsulo za 4 CWDM, ndikuwatembenuzira ku deta yamagetsi ya 4.
Mafunde apakati a njira za 4 CWDM ndi 1271, 1291, 1311 ndi 1331 nm monga mamembala a CWDM wavelength grid akufotokozedwa mu ITU-T G694.2.Ili ndi cholumikizira cha duplex LC cholumikizira mawonekedwe owoneka bwino ndi cholumikizira cha 38-pin cha mawonekedwe amagetsi.Kuti muchepetse kufalikira kwa kuwala munjira yayitali, fiber single-mode (SMF) iyenera kugwiritsidwa ntchito mu gawoli.
Chogulitsacho chimapangidwa ndi mawonekedwe, mawonekedwe owoneka / magetsi komanso mawonekedwe a digito malinga ndi QSFP Multi-Source Agreement (MSA).Lapangidwa kuti likwaniritse zovuta zogwirira ntchito zakunja kuphatikiza kutentha, chinyezi ndi kusokoneza kwa EMI.
Gawoli limagwira ntchito kuchokera ku mphamvu imodzi ya + 3.3V ndi zizindikiro zolamulira zapadziko lonse za LVCMOS / LVTTL monga Module Present, Reset, Interrupt and Low Power Mode zilipo ndi ma modules.A 2-waya serial mawonekedwe akupezeka kuti atumize ndi kulandira zizindikiro zowongolera zovuta komanso kupeza chidziwitso cha digito.Makanema apawokha amatha kuyan'anidwa ndipo mayendedwe osagwiritsidwa ntchito amatha kutsekedwa kuti azitha kusinthasintha kwambiri.
Izi zimatembenuza deta yamagetsi ya 4-channel 10Gb/s kukhala ma CWDM optical signals (kuwala), ndi gulu la 4-wavelength Distributed Feedback Laser (DFB).Kuwala kumaphatikizidwa ndi zigawo za MUX monga deta ya 40Gb / s, kufalitsa kuchokera ku transmitter module kuchokera ku SMF.Ma module olandila amavomereza 40Gb / s CWDM optical signing input, ndi de-multiplexes mu 4 payekha 10Gb / s njira ndi mawonekedwe osiyana.Kuwala kulikonse kwa kutalika kwa mafunde kumasonkhanitsidwa ndi avalanche photodiode (APD), kenako kutulutsidwa ngati data yamagetsi pambuyo pokulitsidwa koyamba ndi TIA kenako ndi positi amplifier.
TheChithunzi cha HUAQ40Eidapangidwa ndi mawonekedwe, kulumikizidwa kwamagetsi / magetsi komanso mawonekedwe owunikira digito malinga ndi QSFP Multi-Source Agreement (MSA).Lapangidwa kuti likwaniritse zovuta zogwirira ntchito zakunja kuphatikiza kutentha, chinyezi ndi kusokoneza kwa EMI.Gawoli limapereka magwiridwe antchito apamwamba kwambiri komanso kuphatikiza kwazinthu, kupezeka kudzera pamawonekedwe a waya awiri.
