ʻO kēia transmitter kahi kiʻekiʻe-index, multi-functional 1550nm internally modulated optical transmitter ma ka pae kiʻekiʻe. Hoʻohana ʻo ia i kahi laser DFB laina kiʻekiʻe, me ka uku hoʻopaʻapaʻa pre-distortion i kūkulu ʻia a me ka mana AGC, APC, a me ATC, kahi e hoʻomaikaʻi nui ai i ka papa kuhikuhi piha o ka ʻōnaehana.
ʻO ST1550I series 1550nm internally modulated optical transmitter ʻo ia ka mea nui no ke kūkulu ʻana i nā pūnaewele hoʻouna lua CATV. Hoʻohana nui ʻia ia no nā lawelawe i hoʻohui ʻia e like me nā hōʻailona kiʻi TV, nā hōʻailona TV kikohoʻe, nā hōʻailona kelepona, a me nā hōʻailona ʻikepili (a i ʻole compressed data). He hopena kiʻekiʻe akā haʻahaʻa ke kumu kūʻai e ʻike ai i ka pāʻani triple a me nā ʻōnaehana hoʻoili pūnaewele FTTx.
Nā hiʻohiʻona hana
1. Hoʻohana ia i ke kani haʻahaʻa haʻahaʻa a me ka laser linearity kiʻekiʻe DFB ma ke ʻano he kumu hōʻailona.
2. ʻO ke kaʻapuni pre-distortion maikaʻi loa e hōʻoia i ka hana kūpono o CTB a me CSO i ka waiwai CNR maʻamau.
3. Hiki i ka mana 'akomi loa'a (AGC) ke ho'opuka pa'a i nā pae ho'okomo RF like 'ole.
4. Hiki ke hoʻonui ʻia nā pūnaewele like ʻole e ka hoʻoponopono OMI.
5. Hoʻomaka ka hana ʻana o nā mea pā i ka wā e piʻi ai ka mahana o ka hihia i 30 ℃.
6. Kākoʻo ʻia ka mana hoʻihoʻi ʻelua, puʻu wela, a me ka hoʻololi ʻakomi.
7. ʻO nā palena hana o ka mīkini holoʻokoʻa e hoʻomaluʻia e ka microprocessor a me ka hōʻike kūlana LCD ma ka papa mua he nui nā hana e like me ka nānāʻana i ke kūlana laser, ka hōʻike hoʻohālikelike, ka hōʻailona hewa, ka mālama pūnaewele, a pēlā aku; i ka manawa e haʻalele ai nā ʻāpana hana o ka laser mai ka pae i ʻae ʻia e ka polokalamu, e hoʻāla koke ka ʻōnaehana.
8. Hāʻawi ʻia ke kikowaena RJ45 maʻamau, kākoʻo i ka hoʻokele pūnaewele mamao o SNMP a me WEB.
