Module-ka SFP wuxuu ka kooban yahay aaladda indhaha, wareegga shaqada iyo is-dhexgalka indhaha. Qalabka indhaha wuxuu ka kooban yahay qaybinta gudbinta iyo helitaanka.
Qaybta gudbinta waa: gelinta qaddar code gaar ah oo calaamadaha korantada ah, iyada oo loo marayo farsamaynta chip darawalka gudaha, wadista laser semiconductor laser (LD) ee diode iftiiminta (LED) si loo soo diro heerka koodhka u dhigma qaabaynta calaamadaha indhaha, iftiinka gudaha waa oo la siiyay wareeg kontorool koronto oo toos ah. Awoodda ishaarada indhaha ee wax soo saarka ayaa weli ah mid deggan.
Qaybta helaysa waa: Module gelinta signalka indhaha ee heerka koodka qaarkood waxa loo beddelaa calaamad koronto iyada oo loo marayo diode ogaanshaha indhaha. Ka dib preamplifer-ka, calaamadda wax-soo-saarka ee heerka waxoogaa ee u dhigma waa heerka PECL. Marka awoodda wax gelinta ee indhaha ay ka yaraato qiimo gaar ah, waxaa la soo saarayaa calaamad digniin ah.
Halbeegyada iyo macnaha modules-yada indhaha
Qaybaha indhaha waxay lahaayeen cabbiro farsamo oo muhiim ah. Si kastaba ha ahaatee, GBIC iyo SFP hot-plug SFP Modules, waxaad u baahan tahay inaad fiiro gaar ah u yeelato saddexda cabbir ee soo socda.
Iyada oo ku saleysan nanometer(nm), waxaa jira saddex nooc oo waaweyn hadda.
850nm (MM, qaab-badan, qiimo jaban laakiin fogaanta gudbinta gaaban, guud ahaan kaliya 500M).
1310nm (SM, Single Mode, luminta gudbinta yar yar, kala firidhsan weyn, guud ahaan loo isticmaalo gudbinta fogaansho dheer in ka badan 40KM, Relay ma si toos ah u gudbin kartaa 120KM).
1550nm (SM, Single Mode, luminta gudbinta yar yar, kala firidhsan weyn, guud ahaan loo isticmaalo gudbinta fogaan dheer ee ka badan 40KM, ma ku celin si toos ah u gudbiyaan 120KM).
Heerka Gudbinta
Tirooyinka bits (BPS) ee xogta la gudbiyo ilbiriqsikiiba.
Hadda Waxaa jira afar module oo SFP ah oo inta badan la isticmaalo. 155Mbps, 1.25Gbps, 2.5Gbps, 10Gbps iyo wixii la mid ah. Sicirka wareejinta inta badan waa dib u socon kara. Sidaa darteed, 155M SFP Module waxa kale oo loo yaqaan FE (100Mbit/s) SFP Module, iyo 1.25G SFP Module waxa kale oo loo yaqaan GE (Gigabit) moduleka indhaha.
Tani waa SFP-da ugu badan ee loo isticmaalo qalabka gudbinta indhaha. Intaa waxaa dheer, heerka gudbintiisa ee nidaamyada kaydinta fiber optic (SAN) waa 2Gbps, 4Gbps, iyo 8Gbps.
Fogaanta gudbinta
Calaamadaha indhaha uma baahna in lagu sii gudbiyo fogaanta halkaas oo si toos ah loogu gudbin karo. Kiiloomitir (oo sidoo kale loo yaqaan kiiloomitir, KM). Tilmaamaha Modules SFP waa sida soo socota: Multi-Mode 550M, Single-Mode 15KM, 40KM, 80KM, iyo 120KM, iwm.
