Hōʻuluʻulu Huahana
ʻO kā mākou hui ka mea hou loa kiʻekiʻe kiʻekiʻe-hopena CATV network optical receiver SR814ST, hoʻohana ka pre-amplifier i ka GaAs MMIC piha, a hoʻohana ka post-amplifier i nā modula GaAs. Me ka optimized circuit circuit a me 10 mau makahiki o ka hoʻolālā hoʻolālā ʻoihana, ua loaʻa i ka hāmeʻa nā hōʻailona hana maikaʻi loa. Eia kekahi, ʻo ka mana microprocessor a me ka hōʻike ʻana i nā ʻāpana kikohoʻe e hana maʻalahi i ka hoʻoheheʻe ʻenehana. ʻO ia ka lako nui e pono ai no ke kūkulu ʻana i ka pūnaewele CATV.
Nā ʻano hana
ʻO kā mākou mea hoʻohana ʻike kiʻekiʻe ʻo CATV ʻo SR814ST e hoʻohana i ka pahu hoʻololi kiʻekiʻe PIN photoelectric hoʻololi, hoʻolālā i ka hoʻolālā kaapuni a me ka hana SMT, a ʻike i ka hoʻouna ʻana i nā hōʻailona photoelectric.
Hāʻawi nā pahu attenuation RF i hoʻolaʻa ʻia i ka attenuation linear pololei, aʻo kā mākou mea hoʻonui GaAs e hāʻawi i ka waiwai kiʻekiʻe a me ka haʻahaʻa haʻahaʻa. Hoʻomalu ʻia ka ʻōnaehana e kahi microcomputer chip hoʻokahi (SCM), me nā ʻāpana hōʻike LCD, ka hana maʻalahi a intuitive, a me ka hana paʻa.
ʻO ka ʻōnaehana AGC e hōʻoia i ka hoʻomau mau ʻana o ka pae puka ma luna o ka mana optical o -9 a +2 dBm me ka liʻiliʻi o ke keakea mai ka CTB a me CSO. Hoʻokomo pū ka ʻōnaehana i kahi kikowaena kamaʻilio ʻikepili i mālama ʻia, hiki ke hoʻopili ʻia i kahi mea pane hoʻokele pūnaewele ʻano II a pili i ka ʻōnaehana hoʻokele pūnaewele. Ua ana ʻia nā ʻenehana ʻenehana āpau e like me GY / T 194-2003, ma lalo o nā kūlana hoʻokolohua maʻamau.
