Chii chinonzi SFP module?
SFP ndiyo chidimbu chepasuru diki inovharika. Iyo compact, inopisa pluggable Optical module yekufonera uye data kutaurirana maapplication. Iyo SFP Optical module inogona kutariswa seyakakwidziridzwa vhezheni yeGBIC Optical module. Kusiyana neGBICs ine SC fiber interfaces, SFPs inouya neLC interfaces (kunyangwe painewo maSFP modules ane SC interfaces) uye ane saizi yemuviri ingangoita hafu yeGBICs, zvichibvumira SFPs kuchengetedza imwe nzvimbo. SFP inobatanidza iyo mamaboard yetiweki zvishandiso (sengerouters, maswichi, zvinoshandura midhiya, kana midziyo yakafanana) kune tambo dzemaziso kana tambo. Panguva imwecheteyo, SFP inowanzoshandiswa maindasitiri kutsanangurwa kunotsigirwa nevazhinji network network vatengesi. Yakagadzirirwa kutsigira SONET, Gigabit Ethernet, Fiber Channel, uye mamwe maitiro ekutaurirana. Chimiro chinoratidzwa mumufananidzo unotevera
Standardization
SFP Optical module haina kudzorwa nechero official standard system, asi inodzorwa nemultilateral chibvumirano (MSA) pakati pevanokwikwidza. SFP yakagadzirwa zvinoenderana neiyo GBIC interface uye inowana yakakwira chiteshi density kupfuura GBIC (nhamba yeOptical module per centimita padivi peiyo mamaboard), ndosaka SFP ichinziwo mini GBIC. Iyo yakabatana diki package Optical module ine saizi yakafanana neSFP, asi inotengeswa kubhodhi reamai sepini pane kuiswa mudivi rekadhi slot.
Nekudaro, mumashandisirwo anoshanda, vamwe vagadziri vetiweki zvishandiso vanoshandisa kiyi nzira yekutyora kuenderana ne "universal" SFP, ndiko kuti, wedzera nzira yekusimbisa kune firmware mudziyo kuitira kuti mudziyo ugone kugonesa yayo Optical module.
Mhando dzakasiyana dzeSFPs
Kune akawanda akasiyana marudzi evatambi uye vanogamuchira eSFP modules anotengeswa pamusika nhasi. Iyi nzira inobvumira vashandisi kusarudza yakakodzera Optical module kune yega yega link. Semuenzaniso, mumhando dzezvino interface, kutapurirana kunogona kukamurwa kuita imwe modhi kana multimode zvichienderana nemhando dzakasiyana dzefiber.
Sezvinoratidzwa mumufananidzo uri pamusoro, uyu mufananidzo unoratidza imwechete fiber module yeSC interface

Kuumbwa kweSFP
Mamiriro ekuumbwa: inonyanya kuumbwa neimwe ye (BOSA yefiber imwe chete; TOSA + ROSA yefiber mbiri), yakasanganiswa nePCBA board negoko, uye ine zvindori zvekudhonza, mabuckles, kuvhura zvikamu, uye mapulagi erabha. Kuti unyatso kusiyanisa emission uye yekugamuchira wavelengths kubva pachitarisiko, mavara akasiyana ekudhonza mhete anowanzo gadzirirwa kusiyanisa parameter mhando dzemodule. Semuenzaniso, muLC single fiber interface, yebhuruu yekudhonza mhete ndeye 1310nm, yepepuru yekudhonza mhete ndeye 1490nm, zvichingodaro.
Iyo SFP module inogadzirwa naShenzhen Haidiwei Optoelectronics Technology Co., Ltd. chigadzirwa chinotengeswa zvakanyanya. Pamusoro pezvo, kune zvakare yakakurumbira kutaurirana Optical module, pluggable Optical module, 1x9 Optical module, dual core Optical module uye zvimwe zvigadzirwa zvemodule zvemhando dzakasiyana. Gamuchirai munhu wese anoda kuve nekunzwisisa kwechigadzirwa. Shenzhen Haidiwei Optoelectronics Technology Co., Ltd. inogona kupa nyanzvi yehunyanzvi sevhisi timu kuti ikushandire.
