Ndị na-ebufe SFP bụ modulu arụmọrụ dị elu, dị ọnụ ala, na-akwado ọnụego data nke 1.25Gbps na anya nnyefe 10KM na SMF.
Transceiver ahụ nwere ngalaba atọ: transmitter laser FP, PIN photodiode nke ejikọtara ya na transimpedance preamplifier (TIA) na unit njikwa MCU. Modulu niile na-emezu ihe achọrọ maka nchekwa laser klas nke mbụ.
Transceivers ndị a dakọtara na SFP Multi-Source Agreement (MSA) na SFF-8472. Maka ozi ndị ọzọ, biko lee SFP MSA.
