Kev koom tes nrog kev sib koom tes ntawm cov neeg muag khoom transceiver thiab chip foundries tsom kom nthuav dav, txhawb nqa los ntawm cov thawj coj zoo li US CHIPS Txoj Cai uas tau faib $ 36 nphom rau kev tsim khoom hauv tsev semiconductor txog Lub Ib Hlis 2025.

Cov qauv evolution txuas ntxiv thawb ciam teb. 1.6T Ethernet specification nyob rau hauv txoj kev loj hlob los ntawm IEEE yuav xav tau cov ntaub ntawv tshiab transceiver thiab optical technologies. Txawm hais tias kev lag luam txais cov modules pluggable los yog hloov mus rau co-pob optics rau cov ultra- kev kub ceev tseem yog ib qho lus nug qhib nrog rau cov kev cuam tshuam tseem ceeb.

Qhov kev tsim kho qhov muag SFP qhov tseem ceeb- kub-swappable transceiver hloov hluav taws xob thiab kho qhov muag teeb liab- tau ua pov thawj zoo kawg li txij li xyoo 2001. Txawm hais tias qhov nrawm tau nce 800-fold thiab kev sib xyaw ua ke tau ntau ntxiv, cov qauv tsim qauv thiab cov qauv tseem muaj nyob. Qhov kev ua neej ntev no qhia tau hais tias cov ntaub ntawv kho qhov muag hloov tau tsim los ntawm pluggable transceivers yuav nyob twj ywm hauv nruab nrab rau kev sib txuas hauv network, txawm tias cov thev naus laus zis tshwj xeeb thiab kev nrawm txuas ntxiv lawv cov kev hloov pauv sai.
