产品介绍:
3端口 DWDM器件主要用于无源波分复用模块,是一种基于TFF(薄膜滤波器)的波分复用技术,具备多种封装尺寸、波长可选,由公共端(COM)、透射端(Pass)、反射端(Reflect)三端口组成;DWDM具有100GHz、200GHz等信道间隔，相对于CWDM而言,极大地提高了工作波长数量,从而大大地增加了信号传输速度和通信容量,适用于长距离,大容量长途干线网,或超大容量的城域网核心节点,广泛应用于电信5G、城域网、骨干网、数据中心等领域。

 

产品特性:
● 低插入损耗 ≦0.6dB
较低的插入损耗,使DWDM器件运用在波分复用系统里面时拥有较低的信号衰减,从而降低对信号发射器的功率要求。
● 高隔离度
较高的隔离度值,使DWDM器件运用在波分复用系统里面多信号传输时进行充分的信号隔离,有效防止信号之间 相互串扰导致传输信号失真。
● 成熟生产工艺
北亿纤通3端口DWDM器件具有成熟的生产工艺,光路采用无胶及半自动条件封装制作,性能稳定可靠,支持-40℃~+85℃
的恶劣环境下工作, 保证信号的稳定传输。
● 系统追溯、品质保证
北亿纤通自主研发的生产信息管理系统,每只产品均有完整的电子流程,确保器件的品质可靠性和追溯性。
● 符合国际标准
北亿纤通的3端口DWDM器件符合RoHS,满足TelcordiaGR-1209-CORE与GR-1221-CORE,也满足行业的168小时PCT可靠性实验。
