Njengamanje, ithrafikhi yesikhungo sedatha iyanda kakhulu, futhi i-bandwidth yenethiwekhi iyaqhubeka nokuthuthukiswa, okuletha amathuba amahle okuthuthukiswa kwamamojula e-optical asheshayo. Ake ngikhulume nawe ngezidingo ezine ezinkulu zesikhungo sedatha sesizukulwane esilandelayo samamojula e-optical.
1. Isivinini esikhulu, sithuthukisa umthamo we-bandwidth
Umthamo wokushintsha wama-chip ucishe uphindwe kabili njalo eminyakeni emibili. I-Broadcom iqhubekile nokwethula uchungechunge lwe-Tomahawk lwama-chip okushintsha kusukela ngo-2015 kuya ku-2020, futhi umthamo wokushintsha ukhuphuke kusukela ku-3.2T kuya ku-25.6T; kulindeleke ukuthi ngo-2022, umkhiqizo omusha uzofinyelela ikhono lokushintsha elingu-51.2T. Izinga lokumboza lamaseva nama-switch okwamanje linama-40G, 100G, 200G, 400G. Ngesikhathi esifanayo, izinga lokudlulisa lamamojula e-optical nalo likhula kancane kancane, futhi lithuthukiswa njalo ngokuya ku-100G, 400G, kanye no-800G.
2. Ukusetshenziswa kwamandla okuphansi, kunciphisa ukukhiqizwa kokushisa
Ukusetshenziswa kwamandla kwaminyaka yonke kwezikhungo zedatha kukhulu kakhulu. Kulinganiselwa ukuthi ngo-2030, ukusetshenziswa kwamandla esikhungo sedatha kuzobalelwa ku-3% kuya ku-13% wokusetshenziswa kwamandla emhlabeni jikelele. Ngakho-ke, ukusetshenziswa kwamandla aphansi nakho kube ngenye yezidingo zamamojula we-optical esikhungo sedatha.
3. Ukuminyana okuphezulu, gcina isikhala
Njengoba izinga lokudlulisa amamojula okukhanya likhula, uma sibheka amamojula okukhanya angu-40G njengesibonelo, ivolumu ehlanganisiwe kanye nokusetshenziswa kwamandla kwamamojula amane okukhanya angu-10G kumele kube ngaphezu kwemojula yokukhanya engu-40G.
4. Izindleko eziphansi
Njengoba umthamo wokushintsha uqhubeka, abathengisi bemishini abadumile bethule amaswishi angu-400G. Ngokuvamile inani lamachweba eswishi liningi kakhulu. Uma amamojula e-optical exhunyiwe, inani kanye nezindleko zikhulu kakhulu, ngakho amamojula e-optical angabizi kakhulu angasetshenziswa ezikhungweni zedatha ngezinga elikhulu.
