Incazelo Yomkhiqizo

1. Isifinyezo Somkhiqizo

Ama-SR812S ayi-receiver yethu ye-CATV yenethiwekhi ebanzi ene-transponder yokuphathwa kwenethiwekhi. I-pre-amp isebenzisa i-all-GaAs MMIC amplifier kanye ne-post-amp isebenzisa i-module ye-GaAs power double amplifier. Umklamo wesekethe olungiselelwe, kanye nolwazi lwethu lobuchwepheshe be-RF lonyaka, imishini ifinyelela inkomba yokusebenza ephezulu. Iyimodeli efanelekile yenethiwekhi ye-CATV.

2. Isici

- Ishubhu yokuguqula i-PIN ene-photoelectric ephendula kakhulu, umklamo we-bandwidth we-1G.
- Ukunciphisa kanye nokulingana kungaba uhlobo lwenkinobho oluguquguqukayo njalonoma faka uhlobo. (Ongakukhetha)
- Ukukhishwa kwamandla okuphindaphinda kabili, inzuzo ephezulu kanye nokuphambuka okuphansi.
- Ukulawulwa kwe-Optical AGC, lapho ububanzi bamandla okufaka we-optical bungu-－7～＋2dBm, izinga lokukhipha alishintshile.
- I-transponder yenethiwekhi ongayikhetha, isekela uhlelo lokuphathwa kwenethiwekhi ye-NMS.
