GWR1200 CATV Node na gani
Bayanin Samfura
GWR1200 Optical Node yana da waje mutu-cast aluminum gidaje fitarwa gaba hanya analog TV, DVB-C da CMTS DS sigina da aika sama na USB modem siginar a yau da kullum ko fashe yanayin a kan guda Bi-directional fiber ko na 2nd fiber. Su ne manufa don ci-gaba fiber zuwa wuraren (FTTP) da kuma fiber zuwa ginin (FTTB) aikace-aikace a CATV da internet cibiyoyin sadarwa. Ƙididdigar GWR1200 tana ba da babban fitarwa na RF har zuwa 1.2 GHz (1218MHz) wanda zai rage ko kawar da buƙatar amplifier post-node a cikin hanyar sadarwa.
Ƙididdigar GWR1200 ita ce manufa don aikace-aikace masu yawa: MDU, jami'o'i, asibitoci da wuraren shakatawa na kasuwanci. GWR1200 yana alfahari da fitowar 50dBmV wanda ke sarrafa kowane girman kafa. Mai watsa hanyar dawowa zai iya zama 1310nm ko 1550nm dangane da buƙatun tsarin. Fasaha WDM na zaɓi yana ba da damar yin aiki ta hanyoyi biyu akan fiber guda ɗaya. Ana ba da masu watsa shirye-shiryen CWDM don haɗa nau'ikan nodes biyu masu yawa akan fiber ɗaya.
A matsayin kumburin gani na waje, GWR1200 ya ƙera 4KV kariya mai ƙarfi a duk tashoshin RF.
GWR1200 za a iya saita mai watsa hanyar dawowa a yanayin fashewa don rage amo hanyar dawowa. Na'urar tana amfani da fiber guda ɗaya kuma tana karɓar sigina na ƙasa a 1550nm kuma ana iya ba da oda masu watsawa azaman ko dai 1310nm ko 1610nm ko CWDM tsayin raƙuman ruwa dangane da buƙatun tsarin. A matsayin na'urar RFOG yana dacewa da DOCSIS® da duk abubuwan gado na HFC na baya na ofis.
