Kune marudzi mazhinji eSFP modules, uye vashandisiwo zvavo kazhinji havana nzira yekutanga pakusarudza SFP modules, kana kusanzwisisa ruzivo, kutenda neupofu mugadziri, zvichikonzera kusakwanisa kusarudza yavo yakakodzera kana yakanakisa musanganiswa.Pazasi pane kupatsanurwa kweSFP modules kubva kune akasiyana maonero ekukubatsira iwe kusarudza.
Kurongwa nechiyero chekutapurirana:
Maererano nemitengo yakasiyana, kune 155M, 622M, 1.25G, 2.125G, 4.25G, 8G, uye 10G.Pakati pavo, 155M uye 1.25G (ese mumbps) anoshandiswa zvakanyanya uye anoshandiswa zvakanyanya mumusika.Iyo tekinoroji yekufambisa ye10G yakawedzera zvishoma nezvishoma, mari yacho iri kudererawo zvishoma nezvishoma, uye kudiwa kuri kukura mukukwira kumusoro;Nekudaro, nekuda kweiyo shoma network yekupinda mwero iripo ikozvino, chiyero chekushandisa chiri padanho rakaderera uye kukura kunononoka.Iyi inotevera nhamba: SFP module ine 1.25G uye 10G kumhanya
Wavelength classification
Zvinoenderana neakasiyana wavelengths (optical wavelengths), kune 850nm, 1310nm, 1550nm, 1490nm, 1530nm, 1610nm.Pakati pavo, iyo module ine wavelength ye850nm ndeye multimode, ine nhambwe yekufambisa isingasviki 2KM (inoshandiswa kune yepakati uye pfupi nhambwe kutapurirana, mukana wakaderera pane mutengo wetambo dzetiweki, uye kurasikirwa kwekutapurirana kwakaderera).Iyo module ine transmission wavelength ye1310nm uye 1550nm imoti imwe chete, ine chinhambwe chekufambisa che2KM-20KM, iyo yakachipa kupfuura mamwe matatu mawavelengths, Saka inoshandiswawo zvakanyanya, kazhinji kusarudza kubva kune idzi sarudzo nhatu zvakakwana.Naked modules (ayo ari akajairwa mamodule ane chero ruzivo) anogona kuvhiringika nyore pasina kuzivikanwa.Kazhinji, vagadziri vanozosiyanisa ruvara rwekudhonza mhete, senge dema rekudhonza mhete yemultimode, ine wavelength ye850nm;Bhuruu imodule ine wavelength ye1310nm;Yero inomiririra module ine wavelength ye1550nm;Purple imodule ine wavelength ye1490nm.

Classification inoenderana nekutapurirana modhi
Multimode SFP
Panyaya yehukuru, dzinenge dzese multimode optical fibers i50/125mm kana 62.5/125mm, uye bandwidth (ruzivo rwekutapurirana simba re optical fiber) kazhinji 200MHz kusvika 2GHz.Paunenge uchishandisa multimode optical transceiver, multimode optical fibers inogona kufambisa madaro anosvika 5 makiromita.Kushandisa mwenje-emitting diode kana lasers semwenje masosi.Mhete yekudhonza kana ruvara rwemuviri inhema.
Single mode SFP
Saizi ye single mode fiber ndeye 9-10 / 125mm, uye ichienzaniswa nemultimode fiber, ine isingaperi bandwidth uye yakaderera kurasikirwa maitiro.Naizvozvo, kana uchitumira pamusoro pemadaro marefu, single mode kutapurirana ndiyo inonyanya kufarirwa.Single mode optical transceiver inowanzoshandiswa kutapurirana kure-kure, dzimwe nguva inosvika 150 kusvika 200 makiromita.Shandisa LD kana LED ine mitsetse yakatetepa inotaridzika semwenje sosi.Mhete yekudhonza kana ruvara rwemuviri ibhuruu, yero, kana yepepuru.(Mawavelengths anoenderana nemavara akasiyana anotsanangurwa zvakajeka paari.)
