3端口 DWDM
Description
產(chǎn)品介紹:
3端口 DWDM器件主要用于無源波分復(fù)用模塊,是一種基于TFF(薄膜濾波器)的波分復(fù)用技術(shù),具備多種封裝尺寸、波長(zhǎng)可選,由公共端(COM)、透射端(Pass)、反射端(Reflect)三端口組成;DWDM具有100GHz、200GHz等信道間隔，相對(duì)于CWDM而言,極大地提高了工作波長(zhǎng)數(shù)量,從而大大地增加了信號(hào)傳輸速度和通信容量,適用于長(zhǎng)距離,大容量長(zhǎng)途干線網(wǎng),或超大容量的城域網(wǎng)核心節(jié)點(diǎn),廣泛應(yīng)用于電信5G、城域網(wǎng)、骨干網(wǎng)、數(shù)據(jù)中心等領(lǐng)域。
產(chǎn)品特性:
● 低插入損耗 ≦0.6dB
較低的插入損耗,使DWDM器件運(yùn)用在波分復(fù)用系統(tǒng)里面時(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。
● 高隔離度
較高的隔離度值,使DWDM器件運(yùn)用在波分復(fù)用系統(tǒng)里面多信號(hào)傳輸時(shí)進(jìn)行充分的信號(hào)隔離,有效防止信號(hào)之間 相互串?dāng)_導(dǎo)致傳輸信號(hào)失真。
● 成熟生產(chǎn)工藝
北億纖通3端口DWDM器件具有成熟的生產(chǎn)工藝,光路采用無膠及半自動(dòng)條件封裝制作,性能穩(wěn)定可靠,支持-40℃~+85℃
的惡劣環(huán)境下工作, 保證信號(hào)的穩(wěn)定傳輸。
● 系統(tǒng)追溯、品質(zhì)保證
北億纖通自主研發(fā)的生產(chǎn)信息管理系統(tǒng),每只產(chǎn)品均有完整的電子流程,確保器件的品質(zhì)可靠性和追溯性。
● 符合國際標(biāo)準(zhǔn)
北億纖通的3端口DWDM器件符合RoHS,滿足TelcordiaGR-1209-CORE與GR-1221-CORE,也滿足行業(yè)的168小時(shí)PCT可靠性實(shí)驗(yàn)。
