SFP-Transceiver: Ujeeddada, noocyada, muuqaalada

Hagaajinta teknoolajiyada gudbinta xogta ayaa keentay in soo bixitaanka of network fiber-optic, taas oo loo baahan yahay in lagu xiro qalabka si ay u isticmaalaan qalab gaar ah - SFP-transceiver. modules SFP ayaa bedelay qalabka more eheeyn loo isticmaalo khadadka GBIC iyo isgaadhsiinta la xawaare Streaming ka badan 100 Mbit per labaad.

aayahooda

SFP-transceivers waxaa loo isticmaalaa sida qalab priemoperedatochnogo. In si kale loo dhigo, waxay u dhaqmaan sida dhex- dhexeeya cable ee fiber-optic ama labada ciyaaryahan unshielded qaloocdo, iyo qalab kaarka network - biiro, router ama modem. Faa'iidada ugu weyn ee isku xira module waa mid aad u yar. Sababo la this, SFP-transceiver la width a of 20 cm meel kartaa ilaa 20 naadi.

Qalabka loo isticmaalo heerka sare xogta (in ka badan 10 megabits per labaad) ee farsamooyinka soo socda: SDH iyo Fiber Channel. Intaa waxaa dheer, qalabka wax caadi ah, oo waa inay awoodaan in ay la tacaalaan saddex nooc oo signal warbaahinta.

Noocyada SFP-Transceiver

Iyada oo ku xidhan hawsha, sida cable fiber-optic, iyo sidoo kale qalabka loo isticmaalo, dhan modules SFP kala qaybsan yihiin sida uu sheegay dhowr shuruudood:

1. Heerka kala iibsiga data. Celceliska SFP-transceiver retransmits signalka at 100 Mb / s iyo 1 Gbit / s, heerarka SFP + XFP oo - ilaa 10 GB / s.
2. Nooca isku xira. SC-Afyare loo isticmaalo in lagu xiro cable-hal fiber a, halkaas oo ay ku soo dhaweynta iyo gudbinta macluumaadka dhacdaa on mid fiber, iyo LC-xira - laba-fiber, halkaas oo ay ku soo dhaweynta iyo gudbinta calaamadaha qaadeen on channels ah.
3. Nooca fiber. In ay ku xidhmaan silig hal loo isticmaalo SM-transceiver iyo multimode - modules MM.
4. awoodda ugu badan ee signalka kala qaado. dabeecad Tani kala duwan ee kala duwan 1310 nm iyo 1550 nm ah xiriir-hal hab, iyo gudahood 850 nm iyo 1310 nm ee fiilooyinka multimode.

transceiver SFP-indhaha kasta wuxuu leeyahay miisaaniyad gaar ah, ama kala duwan oo ka mid ah soo dhoweynta signal iyo gudbinta. Iyada oo marinka iftiinka dhex cable waa signal la dhimay. Farqiga u dhexeeya masaafada ugu badnaan in module waa ay awoodaan in ay soo diri signal ah iyo xoogga daadanayo nuurka helay, oo waxa loo yaqaan miisaaniyadda indhaha. Xogtan ayaa tilmaamay in sheet xogta of transceiver ee dB ah.

La shaqaynta modules

Inta lagu guda jiro suuqa kala iibsiga xogta SFP module shanqarta iftiin signal in spectrum aan la arki karin (oo ay jirto laser gaar ah, taas aawadeed gudaha qalabka). Sidaa darteed gebi ahaanba la mamnuucay in ay eegaan gelin "Isha" qalab si looga fogaado waxyeelo ay ku ileyska.

Ku xiridda transceiver SFP waa inay xirtaan jijin curcurka ah, ka dib markii ay isku xidha in guryaha. Haddii kale, hadda ee dheecaanku electrostatic dhaawici karaan qalabka.

Intaa waxaa dheer, ee "Isha" laser waa xasaasi u ah ciidda, sidaas darteed ha ka qaad, Daboolida hor jeestay on qalabka si shabakadda. Si aad u sii dheerayn module adeega, taxadir in aadan soo saaro cable ka baahneyn.

Xeerarka Xulashada SFP-modules

Dooro ah SFP-transceiver waa in uu ahaadaa si waafaqsan tilmaamaha aad cable fiber-optic. Waxaa lagama maarmaan ah in ay diiradda saaraan arrimaha a yar. Marka hore, waxaa lagama maarmaan ah in si sax ah loo ogaado miisaaniyadda indhaha. Waxaan ku talinaynaa isticmaalaya qalabka khaaska ah. Xaggee jiraan ma jiro, waxaad ka heli kartaa qiimaha "qiyaas ahaan", waxa ku filan in la ogaado masaafada u dhexeysa dhibic ka mid ah soo dhoweynta iyo gudbinta ilaa kilomitir.

Second, go'aamiyo nooca xire on board ka mid ah qalabka network aad. transceiver SFP indhaha waa in lagu soo xulo iyada oo sax ah qufulka la mid ah. Haddii kale, waxaad kaliya ma awoodi doonaan in ay isticmaalaan module ah. Currently suuqa laga heli karaa alaab muusiko oo faseexad ah saddex nooc: Button, Mylar Tab, Bale-xajinta. Waxaad go'aan ka gaari kara nooca aragga.
