E mepụtara OP-QSFP28-01 maka iji na njikọ 100 Gigabit kwa sekọnd n'elu eriri multimode.
Ha kwekọrọ na QSFP28 MSA na IEEE 802.3bm. Akụkụ nnyefe anya nke transceiver ahụ gụnyere usoro VCSEL (Vertical Cavity Surface Emitting Laser) nke nwere ọwa anọ, ihe nchekwa ntinye nke ọwa anọ na onye ọkwọ ụgbọala laser, ihe nlekota nyocha, ihe njikwa na ihe mgbochi. Maka njikwa modulu, ihe njikwa ahụ gụnyere njikọ Two Wire Serial nke elekere na akara data. Ihe nlekota nyocha maka
A na-emejuputa VCSEL bias, okpomọkụ modulu, ike anya ebufere, ike anya natara na voltaji ọkọnọ, a na-enwetakwa nsonaazụ site na TWS interface. A na-ahazi oke mkpu na ịdọ aka ná ntị maka njirimara ndị a na-enyocha. A na-ahazi ọkọlọtọ ma na-eme nkwụsị mgbe
njirimara dị n'èzí oke. A na-edobekwa ọkọlọtọ ma na-emepụta nkwụsị maka mfu nke akara ntinye

Enwere ike ikpuchi nkwụsịtụ niile ma tọgharịa ọkọlọtọ site na ịgụ ndekọ ọkọlọtọ kwesịrị ekwesị. Mmepụta anya ga-agbanyụ maka mfu nke mgbaàmà ntinye ọ gwụla ma agbanyụrụ squelch. Nchọpụta nsogbu ma ọ bụ mwepụ ọwa site na interface TWS ga-eme ka ọwa ahụ gbanyụọ. Ọnọdụ, mkpu/ịdọ aka ná ntị na ozi njehie dị site na interface TWS.
Akụkụ nnata anya nke transceiver ahụ gụnyere usoro fotodiode PIN nke ọwa anọ, usoro TIA nke ọwa anọ, ihe nchekwa mmepụta nke ọwa anọ, ihe nlekota nchọpụta, na ngọngọ njikwa na nkewa. A na-emejuputa ihe nlekota nchọpụta maka ike ntinye anya ma nweta nsonaazụ site na njikọ TWS. A na-ahazi oke mkpu na ịdọ aka ná ntị maka njirimara ndị a na-enyocha. A na-ahazi ma na-eme nkwụsị mgbe njirimara ndị ahụ dị n'èzí oke. A na-ahazikwa ọkọlọtọ ma na-emepụta nkwụsị maka mfu nke mgbaàmà ntinye anya (LOS). A na-ejide ọkọlọtọ niile ma ga-anọgide na ntọala ọbụlagodi ma ọ bụrụ na ọnọdụ mmalite ọkọlọtọ ahụ ehichapụ ma rụọ ọrụ amaliteghachi. Enwere ike ikpuchi nkwụsịtụ niile ma tọgharịa ọkọlọtọ mgbe a gụrụ ndekọ ọkọlọtọ kwesịrị ekwesị. Mmepụta eletriki ga-agbaze maka mfu nke mgbaàmà ntinye (ọ gwụla ma agbanyụrụ squelch) na mwepụ ọwa site na interface TWS. Ozi ọnọdụ na mkpu/ịdọ aka ná ntị dị site na interface TWS.
