KATERANGAN
Transceiver SFP awujud modul kanthi kinerja dhuwur lan hemat biaya sing ndhukung kecepatan data 1.25Gbps lan jarak transmisi 10KM nganggo SMF.
Transceiver iki kasusun saka telung bagean: pemancar laser FP, fotodioda PIN sing terintegrasi karo preamplifier trans-impedance (TIA) lan unit kontrol MCU. Kabeh modul nyukupi syarat keamanan laser kelas I.
Transceiver-transceiver iki kompatibel karo SFP Multi-Source Agreement (MSA) lan SFF-8472. Kanggo informasi luwih lanjut, delengen SFP MSA.

KESALAHAN
minangka output kolektor/drain terbuka, sing kudu ditarik munggah nganggo resistor 4.7k - 10k Ohm ing papan host yen dimaksudake kanggo digunakake.
Tegangan pull-up kudune antara 2.0V nganti Vcc + 0.3V. Output sing dhuwur nuduhake kesalahan pemancar sing disebabake dening arus bias TX utawa daya output TX sing ngluwihi ambang alarm sing wis disetel. Output sing endhek nuduhake operasi normal. Ing kahanan endhek, output ditarik menyang
<0.8V. (utawa <0.8V)
3. Output laser dipateni ing TDIS
>2.0V utawa mbukak, diaktifake ing TDIS
<0.8V. (utawa <0.8V)
4. Kudune ditarik munggah nganggo 4.7k - 10kohms ing papan host menyang voltase antarane 2.0V lan 3.6V. MOD_DEF(0) narik garis cendhek kanggo nandhakake modul wis dipasang.
5. LOS iku output kolektor terbuka. Iki kudu ditarik munggah nganggo 4.7k - 10 kohms ing papan host menyang voltase antarane 2.0V lan 3.6V. Logika 0 nuduhake operasi normal; logika 1 nuduhake ilang sinyal.
