SHARAXAADA
Qalabka gudbinta SFP waa qaybo waxqabad sare leh, kharash-ool ah oo taageeraya heerka xogta ee 1.25Gbps iyo masaafada gudbinta 10KM oo leh SMF.
Qalabka gudbiyaha wuxuu ka kooban yahay saddex qaybood: gudbiye laysar ah oo FP ah, sawir-qaade PIN ah oo lagu daray qalab hor-u-qaadis ah oo transimpedance preamplifier (TIA) iyo cutubka xakamaynta MCU. Dhammaan qaybaha waxay buuxiyaan shuruudaha badbaadada laysarka fasalka I.
Qalabka gudbinta ayaa la jaan qaadaya Heshiiska Ilo-wareed ee badan ee SFP (MSA) iyo SFF-8472. Wixii macluumaad dheeraad ah, fadlan tixraac SFP MSA.

waa wax soo saar furan oo ururiya/daadi ah, kaas oo la jiidi karo iyadoo la adeegsanayo iska caabin 4.7k – 10k Ohms ah oo ku taal guddiga martida loo yahay haddii loogu talagalay in loo isticmaalo.
Danabka jiidista kor u kaca waa inuu u dhexeeyaa 2.0V ilaa Vcc + 0.3V. Wax soo saar sare wuxuu muujinayaa cillad gudbiye oo ay sababtay korontada TX ee xaglaha ah ama awoodda wax soo saarka TX oo dhaaftay marinnada digniinta ee hore loo dejiyay. Wax soo saar hooseeya wuxuu muujinayaa hawlgal caadi ah. Xaaladda hoose, wax soo saarka waxaa loo jiidayaa
