SFP Module e na le sesebelisoa sa optical, potoloho e sebetsang le sebopeho sa optical. Sesebelisoa sa optical se na le likarolo tse fetisang le tse amohelang.
Karolo ea phetisetso ke: tlhahiso ea sekhahla se itseng sa khoutu ea mats'oao a motlakase, ka ts'ebetso ea chip ea mokhanni ea kahare, ho khanna semiconductor laser (LD) ea diode e khanyang e khanyang (LED) ho romella lets'oao la optical code e tsamaisanang le eona, leseli le kahare ke e fanoang ka potoloho ea taolo ea phepelo ea motlakase e iketsang. Matla a pontšo ea optical a ntse a tsitsitse.
Karolo e amohelang ke: optical signal input module ea tekanyo e itseng ea khoutu e fetoloa letšoao la motlakase ka diode ea optical discovery. Ka mor'a preamplifer, lets'oao la tlhahiso ea sekhahla se lekanang sa sekhahla ke boemo ba PECL. Ha matla a optical a input a le tlase ho boleng bo itseng, lets'oao la alamo le hlahisoa.
Mekhahlelo le moelelo oa li-module tsa optical
Li-module tsa Optical li ne li e-na le litekanyetso leha e le life tsa bohlokoa tsa tekheniki. Leha ho le joalo, bakeng sa GBIC le SFP hot-plug SFP Modules, o hloka ho ela hloko lintlha tse tharo tse latelang.
Ho ipapisitsoe le nanometer(nm), ho na le mefuta e meraro ea mantlha hajoale.
850nm (MM, mekhoa e mengata, e theko e tlaase empa sebaka se sekhutšoanyane sa phetisetso, hangata ke 500M feela).
1310nm (SM, Mokhoa o le Mong, tahlehelo e nyane ea phetisetso, phetisetso e kholo, hangata e sebelisetsoa phetisetso ea sebaka se selelele ho feta 40KM, ha ho relay e ka fetisang 120KM ka kotloloho).
1550nm (SM, Mokhoa o le Mong, tahlehelo e nyane ea phetisetso, phetisetso e kholo, hangata e sebelisetsoa phetisetso ea sebaka se selelele ho feta 40KM, ha ho replay e fetisang 120KM ka kotloloho).
Sekhahla sa phetiso
Linomoro tsa li-bits (BPS) tsa data tse fetisoang ka motsotsoana.
Hajoale. Ho na le li-Module tsa SFP tse 'ne tse sebelisoang hangata. 155Mbps, 1.25Gbps, 2.5Gbps, 10Gbps joalo-joalo. Sekhahla sa phetiso hangata se tsamaellana morao. Ka hona, 155M SFP Module e boetse e bitsoa FE (100Mbit / s) SFP Module, 'me 1.25G SFP Module e boetse e bitsoa GE (Gigabit) optical module.
Ena ke SFP e sebelisoang ka ho fetisisa ho lisebelisoa tsa optical transmission. Ho phaella moo, litekanyetso tsa eona tsa phetisetso ho li-fiber optic storage systems ( SAN) ke 2Gbps, 4Gbps, le 8Gbps.
Sebaka sa phetiso
Letšoao la optical ha le hloke hore le fetisetsoe hole moo le ka fetisetsoang ka ho toba. Ka lik'hilomithara (tseo hape li bitsoang lik'hilomithara, KM). Litlhaloso tsa SFP Modules ke tse latelang: Multi-Mode 550M, Single-Mode 15KM, 40KM, 80KM, le 120KM, joalo-joalo.
