IINKCAZELO
Ii-transceivers ze-SFP zisebenza kakuhle kakhulu, zixabisa kancinci, zixhasa isantya sedatha se-1.25Gbps kunye nomgama wokudluliselwa kwe-10KM kunye ne-SMF.
I-transceiver inamacandelo amathathu: i-FP laser transmitter, i-PIN photodiode edityaniswe ne-trans-impedance preamplifier (TIA) kunye neyunithi yolawulo ye-MCU. Zonke iimodyuli ziyahlangabezana neemfuno zokhuseleko lwe-laser yeklasi yoku-1.
Iitransceivers ziyahambelana ne-SFP Multi-Source Agreement (MSA) kunye ne-SFF-8472. Ukuze ufumane ulwazi oluthe vetshe, nceda ujonge i-SFP MSA.

IMFALELO
yimveliso evulekileyo yokuqokelela/yokukhupha amanzi, ekufuneka itsalwe phezulu nge-resistor ye-4.7k – 10k Ohms kwibhodi yokusingatha ukuba yenzelwe ukusetyenziswa.
I-voltage yokutsala kufuneka ibe phakathi kwe-2.0V ukuya kwi-Vcc + 0.3V. I-output ephezulu ibonisa impazamo ye-transmitter ebangelwa yi-TX bias current okanye amandla e-TX output adlula i-alamu esele imiselwe. I-output ephantsi ibonisa ukusebenza okuqhelekileyo. Kwimeko ephantsi, i-output itsalelwa kwi
<0.8V.
3. Ukuphuma kwelaser kukhutshaziwe kwi-TDIS
>2.0V okanye ivuliwe, ivuliwe kwi-TDIS
<0.8V.
4. Kufuneka itsalwe phezulu nge-4.7k - 10kohms kwibhodi yomncedisi ukuya kwi-voltage ephakathi kwe-2.0V kunye ne-3.6V. I-MOD_DEF(0) itsala umgca osezantsi ukubonisa ukuba imodyuli ixhunyiwe.
