Incazelo Eningiliziwe Yokulahleka Kokumuncwa Ezintweni Ze-Optical Fiber
Izinto ezisetshenziselwa ukwenza imicu ye-optical zingamunca amandla okukhanya. Ngemva kokuba izinhlayiya ezisezintweni ze-fiber optical zimunca amandla okukhanya, zikhiqiza ukudlidliza nokushisa, futhi zichithe amandla, okuholela ekulahlekelweni kokumuncwa. Lesi sihloko sizohlaziya ukulahlekelwa kokumuncwa kwezinto zefiber optical. Siyazi ukuthi udaba lwakhiwe ama-athomu nama-molecule, futhi ama-athomu akhiwa ama-nuclei e-athomu ...Funda kabanzi -
“Iphalethi Yombala” Yezwe Le-Fiber Optic: Kungani Amabanga Wokudlulisa Amamojula Okukhanya Ehluka Kakhulu Kakhulu
Emhlabebeni wezokuxhumana ngefiber optical, ukukhetha ubude begagasi bokukhanya kufana nokushuna isiteshi somsakazo—ngokukhetha kuphela "imvamisa" efanele lapho amasignali angasakazwa ngokucacile nangokuzinza. Kungani amanye amamojula abonakalayo enebanga lokudlulisela elingamamitha angama-500 nje, kanti amanye angahamba amakhilomitha angamakhulu? Imfihlo ilele \"embaleni\" wokukhanya—ukuthi ...Funda kabanzi -
Umehluko phakathi kokushintsha kwe-PoE namaswishi ajwayelekile
Ezweni elihlala livela lobuchwepheshe benethiwekhi, ukukhetha ukushintsha kubalulekile ekusebenzeni kahle kwenethiwekhi nokusebenza. Phakathi kwezinhlobo eziningi zokushintshwa, amaswishi Amandla phezu kwe-Ethernet (PoE) athole ukunakwa okubalulekile ngenxa yezici zawo ezihlukile. Ukuqonda umehluko phakathi kokushintsha kwe-PoE nokushintsha okujwayelekile kubalulekile kumabhizinisi nakumuntu ngamunye...Funda kabanzi -
Uyini umehluko phakathi kwembobo yokubona kanye nembobo kagesi yeswishi?
Emhlabeni wokuxhumana, amaswishi adlala indima ebalulekile ekuxhumeni amadivayisi nasekulawuleni ithrafikhi yedatha. Njengoba ubuchwepheshe buthuthuka, izinhlobo zezimbobo ezitholakala kumaswishi ziye zahlukahluka, kanti izimbobo ze-fiber optic nezikagesi yizona ezivame kakhulu. Ukuqonda umehluko phakathi kwalezi zinhlobo ezimbili zamachweba kubalulekile konjiniyela benethiwekhi nochwepheshe be-IT lapho beklama futhi besebenzisa ukusebenza kahle...Funda kabanzi -
'Iphalethi yombala' emhlabeni we-fiber optic: kungani ibanga lokudlulisela lamamojula optical lihluka kakhulu
