Ukuhlaziywa okujulile kwezimiso zokusebenza kanye nokusetshenziswa kwama-duplexer, ama-triplexer nama-quadplexer

Ezinhlelweni zesimanje zokuxhumana ezingenazintambo, ama-duplexer, ama-triplexer nama-quadplexer ayizici ezibalulekile zokungenzi lutho zokufeza ukudluliswa kwesignali enamabhande amaningi. Zihlanganisa noma zihlukanise amasiginali kumabhendi amafrikhwensi amaningi, okuvumela amadivayisi ukuthi adlulise futhi amukele amabhendi amafrikhwensi amaningi ngesikhathi esisodwa ngenkathi abelana ngezinti. Naphezu kokuhluka kwamagama nezakhiwo, izimiso zabo eziyisisekelo ziyefana, umehluko omkhulu yinombolo nobunkimbinkimbi bamabhendi emvamisa acutshungulwayo.

I-Duplexer

I-duplexer iqukethe izihlungi ezimbili ezabelana ngembobo efanayo (ngokuvamile i-antenna) futhi ezisetshenziselwa ukwenza imisebenzi yokudlulisa (Tx) nokwamukela (Rx) kudivayisi efanayo. Isetshenziswa kakhulu ezinhlelweni ze-frequency division duplex (FDD) ukuvimbela ukuphazamiseka okuhlanganyelwe ngokuhlukanisa ukudlulisa nokwamukela amasiginali. Ama-Duplexer adinga izinga eliphezulu lokuzihlukanisa, ngokuvamile elingaphezu kuka-55 dB, ukuze kuqinisekiswe ukuthi isignali edlulisiwe ayithinti ukuzwela komamukeli.

I-Triplexer

I-triplexer iqukethe izihlungi ezintathu ezabelana ngembobo efanayo. Ivumela idivayisi ukuthi icubungule amasiginali asuka kumabhendi amafrikhwensi amathathu ahlukene ngesikhathi esisodwa futhi ivamise ukusetshenziswa ezinhlelweni zokuxhumana ezidinga ukusekela amabhendi amafrikhwensi amaningi ngesikhathi esisodwa. Idizayini ye-triplexer idinga ukuqinisekisa ukuthi ibhendi yokudlula yesihlungi ngasinye ayilayishi ezinye izihlungi futhi inikeze ukuhlukaniswa okwanele ukuvimbela ukuphazamiseka phakathi kwamabhendi efrikhwensi.

I-Quadplexer

I-quadplexer iqukethe izihlungi ezine ezabelana ngembobo efanayo. Ivumela idivayisi ukuthi icubungule amasignali avela kumabhendi amafrikhwensi amane ahlukene ngesikhathi esisodwa futhi ifanele izinhlelo zokuxhumana eziyinkimbinkimbi ezidinga ukusebenza kahle kwe-spectral, njengobuchwepheshe bokuhlanganisa inkampani yenethiwekhi. Idizayini eyinkimbinkimbi ye-quadplexer iphakeme kakhulu futhi idinga ukuhlangabezana nezidingo eziqinile zokuhlukanisa ukuze kuqinisekiswe ukuthi amasignali phakathi kwamabhendi efrikhwensi awaphazamisi enye nenye.

Umehluko omkhulu

Inombolo yamabhendi efrikhwensi: Ama-Duplexer acubungula amabhendi amabili efrikhwensi, ama-triplexers acubungula amabhendi amafrikhwensi amathathu, futhi ama-quadplexer acubungula amabhendi amane efrikhwensi.

Ubunkimbinkimbi bedizayini: Njengoba inani lamabhendi emvamisa likhula, ubunkimbinkimbi bomklamo kanye nezidingo zokuzihlukanisa nazo ziyanda ngokufanele.

Izimo zohlelo lokusebenza: Ama-Duplexer avame ukusetshenziswa ezinhlelweni eziyisisekelo ze-FDD, kuyilapho ama-triplexer nama-quadplexer asetshenziswa ezinhlelweni zokuxhumana ezithuthukisiwe ezidinga ukusekela amabhendi amafrikhwensi amaningi ngasikhathi sinye.

Ukuqonda izindlela zokusebenza kanye nomehluko wama-duplexer, ama-triplexer, nama-quadplexer kubalulekile ekuklameni nasekuthuthukiseni izinhlelo zokuxhumana ezingenantambo. Ukukhetha uhlobo olufanele lwe-multiplexer kungathuthukisa ngempumelelo ukusetshenziswa kwe-spectrum yesistimu kanye nekhwalithi yokuxhumana.
