Ngokuthuthuka okusheshayo kwenethiwekhi, imojula ye-SFP optical isiyingxenye ebalulekile yohlelo lwenethiwekhi.Ngakho-ke kungakanani okwaziyo ngephrothokholi ye-SFP?Namuhla ake ngikunikeze isingeniso esifushane sephrothokholi ye-SFP-8472.I-Sff-8472 iyiphrothokholi enemithombo eminingi yokuqapha kwedijithali...

I-WiFi6 entsha isekela imodi engu-802.11ax, ngakho-ke yini umehluko phakathi kwemodi engu-802.11ax ne-802.11ac?Uma kuqhathaniswa ne-802.11ac, i-802.11ax iphakamisa ubuchwepheshe obusha bokuphindaphinda kwendawo, obungakwazi ukuhlonza nokuhlehlisa izingxabano zokusebenzelana komoya.Ngaleso sikhathi, ingakwazi ukukhomba izimpawu zokuphazamiseka ngemuva...

Womabili amamojula we-fiber eyodwa kanye ne-dual fiber optical angadlulisela futhi awamukele.Njengoba lezi zokuxhumana ezimbili kufanele zikwazi ukudlulisa nokwamukela.Umehluko ukuthi imojuli eyodwa ye-fiber optical inembobo eyodwa kuphela.Ubuchwepheshe be-Wavelength division multiplexing (WDM) busetshenziselwa ukuhlanganisa ama-rece ahlukene...

1. Ukubukeka okuhlukile: I-double fiber optical module: Kunamasokhethi amabili e-fiber optical, ngokulandelana, ukuthumela (TX) kanye nokwamukela (RX) amachweba optical.Kudingeka kufakwe imicu emibili ye-optical, futhi izimbobo ze-optical ezahlukene kanye nemicu yokubona isetshenziselwa ukudluliswa kwedatha nokwamukela;Lapho du...

I-Optical module DDM iyindlela yokuqapha imingcele.Ayinayo imisebenzi ye-alamu neyesixwayiso kuphela, kodwa futhi nokubikezela amaphutha nemisebenzi yendawo enephutha.Kunezindlela ezimbili eziyinhloko zokubuka ulwazi lwe-DDM lwemojula yokubona: i-SNMP nomyalo.1. I-SNMP, okungukuthi Abaphathi Benethiwekhi Abalula...

1. Isibikezelo sempilo yemojula ye-Optical Ngokuqapha kwesikhathi sangempela se-voltage esebenzayo kanye nezinga lokushisa ngaphakathi kwemojula ye-transceiver, umlawuli wesistimu angathola ezinye izinkinga ezingaba khona: a.Uma i-voltage ye-Vcc iphezulu kakhulu, izoletha ukuwohloka kwamadivayisi we-CMOS;I-voltage ye-Vcc iphansi kakhulu, a...
