雙窗耦合器(DWC)采用非對(duì)稱耦合技術(shù)制造。普通器件帶寬可達(dá)到±40nm,超寬帶器件可擴(kuò)展到±80nm。雙窗寬帶耦合器在1310nm和1550nm通信窗口上具有相同的耦合比,以及具有低插入損耗和低PDL。該產(chǎn)品廣泛應(yīng)用于通信系統(tǒng)、CATV和FTTH。
產(chǎn)品特性
● 低附加損耗,使器件運(yùn)用時(shí)擁有較低的信號(hào)衰減,從而降低對(duì)信號(hào)發(fā)射器的功率要求。
● 雙窗帶寬,普通器件帶寬可達(dá)到±40nm,超寬帶器件可擴(kuò)展到±80nm。
● 北億纖通 的雙窗耦合器具有成熟的生產(chǎn)工藝,支持-40℃~+85℃ 的惡劣環(huán)境下工作,性能穩(wěn)定可靠。
● 北億纖通的雙窗光纖耦合器符合RoHS,滿足TelcordiaGR-1209與GR-1221。
