IMINININGWANE YOMKHIQIZO

Ithimba lethu ngokuqeqeshwa okunekhono. Ulwazi lochwepheshe abanekhono, umuzwa oqinile wesevisi, ukuhlangabezana nezidingo zesevisi zamakhasimende Ezitolo Zase-Factory I-China Factory 1550nm TV RF Passive Optical Network (PON) Cable Cable Modem Gpon/Gepon ONU Rfog Fiber FTTH Mini Wdm Optical Micronode, Ngoba sihlala nalo mugqa cishe iminyaka eyi-10. Sithole usizo lwabahlinzeki abaphumelela kakhulu ngekhwalithi enhle namanani. Futhi besinabahlinzeki bempahla abanekhwalithi ephezulu ephansi. Manje izimboni eziningi ze-OEM zibambisane nathi futhi.

Incazelo Yomkhiqizo

I-RFoG isho ukuthi “Imvamisa yomsakazo phezu kwengilazi”. Izinga lobuchwepheshe likhishwa yi-SCTE kudokhumenti i-SCTE-174-2010, echaza imodi yokuqhuma ye-CATV yomzila wokubuyisa i-laser evula futhi ivalwe lapho inodi yokubona yezindlela ezimbili ithola amasignali emodemu yekhebula ekhuphuka nomfula. Imisindo yendlela yokubuya iyinkinga enkulu yesistimu ye-CATV yezindlela ezimbili. Wonke amamodemu ekhebula noma imisindo yetheminali ye-CATV ibuyiselwa ku-Headend. Kuhlelo lwe-RFoG PON, i-micronode ye-RFoG exhuma nemodemu yekhebula elisebenzayo ivula kuphela ngenkathi amanye ama-micronode e-RFoG evaliwe. Kunesignali eyodwa kuphela ye-RFoG micronode yokubuyisela ku-CMTS, imisindo emincane kakhulu kunohlelo oluvamile lwe-CATV lwezindlela ezimbili.

Njengoba iziteshi eziningi ezibophezela ohlelweni lwe-Docsis 3.0 kanye ne-Docsis 3.1, kuzoba nenkinga ye-OBI (Optical Beat Interference) ngenxa yama-lases we-wavelength amabili noma ngaphezulu afika ku-photodiode eyodwa ngesikhathi esisodwa. Ukuze ugweme i-OBI, kufanele kube namaza wamaza e-laser ahlukile ku-RFoG Micronode kusistimu ye-PON efanayo.

I-RFoG Micronode inika amandla i-CMTS kanye nezinsiza zeModemu Yekhebula zisuka ku-HFC ziye ku-PON “I-Fiber iya ekhaya”.

I-GFH2009 RFoG MicroNode iklanyelwe ukwamukela i-RF yokusakaza engu-1550nm noma ividiyo ye-IP HD evela ku-Passive Optical Network (PON) futhi ithumele amasignali emodemu yekhebula ekhuphukayo ku-1610nm noma enye i-wavelength ye-CWDM. I-GFH2009 isekela ukudluliselwa kwemodi yokuqhuma kwesiginali ye-RF, okuvumela imodemu yekhebula eyodwa ukuthi ixhumane ne-CMTS esigabeni sesikhathi se-TDMA. I-GFH2009 ikhipha izinsiza ze-RF ezilandelanayo ezimbili. I-GFH2009 yakhelwe ukusekela i-DOCSIS2.0, DOCSIS3.0 kanye ne-DOCSIS3.1.

Ezinye izici:

• I-Compact Aluminium Housing.

• 1002/1218MHz indlela eya phambili yomkhawulokudonsa we-RF.

• 17dBmV RF okukhiphayo kwe-FTTH.

• I-ALC isebenza kahle kokuthi -7dBm~+1dBm optical input.

• 5~42MHz/85MHz/204MHz buyisela umkhawulokudonsa we-RF.

• Hlehlisa i-RF ngaphezulu kwe-1310nm noma i-1610nm DFB laser esebenza ngemodi yokuqhuma.

• Inketho ye-laser yendlela yokubuya ye-CWDM ebiza izindleko mahhala ye-OBI.

• Ukuboniswa kwe-LED phambili futhi kubuyisele isimo sokusebenza sokusebenza.

• I-6KV Surge Protection.

• Amandla angu-12V DC embobeni ye-RF.
