Emebere OP-QSFP28-01 maka ojiji na 100 Gigabit njikọ nke abụọ n'elu eriri ụdị ọnọdụ.
Ha dabara na QSFP28 MSA na IEEE 802.3bm. Akụkụ transmitter ngwa anya nke transceiver na-agụnye 4-ọwa VCSEL (Vertical Cavity Surface Emitting Laser), ihe ntinye ntinye ọwa 4 na ọkwọ ụgbọ ala laser, nyocha nyocha, njikwa na mgbochi mkparị. Maka njikwa modul, njikwa njikwa na-agụnye interface elekere abụọ na akara data. Nyocha nyocha maka
VCSEL ele mmadụ anya n'ihu, ọnọdụ okpomọkụ modul, ike anya na-ebufe, ike anya enwetara na voltaji ọkọnọ na-emejuputa atumatu yana nsonaazụ dị site na interface TWS. Edobere oti mkpu na ọnụ ụzọ ịdọ aka ná ntị maka njirimara enyochara. A na-edobe ọkọlọtọ yana nkwụsịtụ mgbe ihe
àgwà dị n'èzí ọnụ ụzọ. Edokwa ọkọlọtọ yana nkwụsịtụ maka mfu nke mgbaama ntinye

Enwere ike kpuchie nkwụsịtụ niile ma megharịa ọkọlọtọ site na ịgụ akwụkwọ ndekọ ọkọlọtọ kwesịrị ekwesị. Mmepụta ngwa anya ga-akụda maka mfu nke mgbaama ntinye ọ gwụla ma enwere nkwarụ squelch. Nchọpụta mmejọ ma ọ bụ nkwụsị ọwa site na interface TWS ga-ewepụ ọwa ahụ. Ọnọdụ, mkpu/ịdọ aka ná ntị na ozi mmejọ dị site na interface TWS.
Akụkụ nke nnata anya nke transceiver na-agụnye 4-ọwa PIN photodiode array, ọwa 4 TIA array, ihe ntanye mmepụta ọwa 4, nyocha nyocha, na njikwa na mgbochi mkparị. A na-emejuputa ihe nleba anya nyocha maka ike ntinye anya yana nsonaazụ dị site na interface TWS. Edobere oti mkpu na ọnụ ụzọ ịdọ aka ná ntị maka njirimara enyochara. A na-edobe ọkọlọtọ yana nkwụsịtụ mgbe njirimara dị na mpụga ọnụ ụzọ. Edokwa ọkọlọtọ yana nkwụsịtụ maka mfu nke mgbama ntinye anya (LOS). Akpọchiri ọkọlọtọ niile, a ga-edobe edobe ma ọ bụrụ na ọnọdụ na-amalite ọkọlọtọ ga-ekpochapụ ma malitekwa ọrụ. Enwere ike kpuchie nkwụsịtụ niile ma tinyegharịa ọkọlọtọ mgbe ị na-agụ akwụkwọ ndekọ ọkọlọtọ kwesịrị ekwesị. Ihe mmepụta eletrik ga-adaba maka nkwụsị nke mgbaàmà ntinye (ọ gwụla ma squelch nwere nkwarụ) na nkwụsị ọwa site na interface TWS. Ọnọdụ na ozi mkpu/ịdọ aka ná ntị dị site na interface TWS.
