I-Mod Def 0 iboshelwe phansi nge-resistor engu-100 ohm ukukhombisa ukuthi imojuli ikhona . I-Mod-Def 1 iwumugqa wewashi we-serial interface yezintambo ezimbili ku-ID ye-serial ozikhethela yona I-Mod-Def 2 iwumugqa wedatha we-serial interface yezintambo ezimbili zochungechunge lwe-ID 4. I-LVTTL ihambisana ne-voltage ephezulu engu-2.5V. Ayisekelwe ku-HTSFP-24-111X 5. I-RD-/+: Lena imiphumela yomamukeli ohlukile. Ziyi-ac ehambisana nemigqa ehlukile engu-100 ohm okufanele iqedwe ngomehluko we-100 ohm ku-SerDes yomsebenzisi. I-ac coupling yenziwa ngaphakathi kwemojuli futhi ngaleyo ndlela ayidingeki ebhodini lomsingathi. Ukushintshashintsha kwamandla kagesi kule migqa kuzoba phakathi kuka-370 no-2000 mV umehluko (185 – 1000 mV single iqedwe) uma iqedwa kahle. Lawa mazinga ahambisana nokushintshashintsha kwamandla kagesi e-CML kanye ne-LVPECL. 6. I-VCCR kanye ne-VCCT yizinto ezinikezwa amandla ezitholayo nezidlulisa amandla.
