Ambiri mwa ma modules optical amagwiritsidwa ntchito pamsana wamsana wa optical fiber network, ndipo transceiver optical ndi chabe chipangizo chowonjezera chingwe cha intaneti. Kodi pali kusiyana kotani pakati pa ma module a optical ndi ma transceivers opanga? 1. Optical modules ndi zowonjezera, zomwe zimagwiritsidwa ntchito nthawi zambiri ...

Monga mamembala awiri akulu a optical network access, EPON ndi GPON aliyense ali ndi zoyenerera zake, amapikisana wina ndi mzake, amathandizana, ndikuphunzira kuchokera kwa wina ndi mnzake. Zotsatirazi zidzawafananiza m'mbali zosiyanasiyana. Rate EPON imapereka ulalo wokhazikika ndi kutsika kwa 1.25 Gbps, kutengera mzere wa 8b/10b c...

1.1 Passive Optical splitter Passive Optical splitter ndi gawo lofunikira pa netiweki ya PON. Ntchito ya passive optical splitter ndiyo kugawa mphamvu ya kuwala ya chizindikiro chimodzi cholowetsa muzotulutsa zingapo. Nthawi zambiri, chogawa chimakwaniritsa kugawanika kwa kuwala kuchokera ku 1: 2 mpaka 1:32 kapena ngakhale ...

Kuyerekezera njira zisanu za PON zochokera ku FTTX Njira yamakono yopezera ma bandwidth apamwamba kwambiri imachokera ku PON-based FTTX access. Mfundo zazikuluzikulu ndi malingaliro omwe akukhudzidwa ndi kusanthula mtengo ndi izi: ● Mtengo wa zipangizo za gawo lofikira (kuphatikizapo zipangizo zosiyanasiyana zopezera ndi mizere...

GPON ndi chiyani? Tekinoloje ya GPON (Gigabit-Capable PON) ndi m'badwo waposachedwa wa Broadband passive Optical Integrated access standard yotengera mulingo wa ITU-TG.984.x. Ili ndi zabwino zambiri monga bandwidth yayikulu, kuchita bwino kwambiri, kuphimba kwakukulu, komanso mawonekedwe ogwiritsira ntchito olemera. Othandizira ambiri amaganizira ...

Pali magetsi ambiri owunikira pa fiber optic modemu, ndipo titha kuweruza ngati zida ndi maukonde ndizolakwika kudzera mu kuwala kowonetsa. Nawa zizindikiro zodziwika bwino za modemu ndi matanthauzo ake, chonde onani mwatsatanetsatane mwatsatanetsatane pansipa. 1. Pofuna kuwongolera malo...
