波分复用器
AWG CWDM4 模块
Description
产品介绍:
北亿纤通的 AWG CWDM4模块基于硅基芯片技术,拥有紧凑性、易组装的结构以及很好的可靠性,可替代TFF(薄膜滤波器)型CWDM,并被广泛用在40G、100G高速有源光模块中进行光信号的复用和解复用,如:QSFP+、QSFP28等。
产品特性:
● 足够的工作带宽 (有效满足高低温波长漂移问题)
AWG CWDM4每个ITU通带均有足够的工作带宽,在高低温的影响下都可以保持ITU最理想的插入损耗指标,光信号始终逃不出AWG CWDM4的工作带宽区间。
● 优质的均匀性(较小的通道一致性)
因为采用的平面波导技术,AWG CWDM4有非常好的通道均匀性,通道之的插入损耗差异较小,无需特别对个别通道进行功率补偿。
● 紧凑设计(尺寸紧凑与微弯光纤的完美结合)
AWG CWDM4器件可安装在非常狭窄的空间内,其主体尺寸能压缩到长15x宽2x高2mm以内,且采用的是Corning ClearCurve ZBL光纤,该光纤弯曲半径达到了5mm,几乎零弯曲损耗,具有高保真、高传输速率。
● 符合国际标准
北亿纤通的AWG CWDM4模块符合RoHS,满足TelcordiaGR-1209-CORE与GR-1221-CORE。
