CWDM 复用&解复用 LGX模块
Description
产品介绍:
北亿纤通的CWDM复用&解复用LGX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;它将不同波长的光信号复用至单根光纤进行传输,在接收端使用解复用将光纤中的信号分解为不同波长的信号,北亿纤通配备单纤或双纤两种传输模式;因CWDM的宽波段、对系统设备的低要求等优势,已在城域网接入层占据的重要的位置。
产品特性:
● 低插入损耗
较低的插入损耗,使CWDM LGX模块运用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CWDM LGX模块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
北亿纤通的CWDM LGX模块具有成熟的生产工艺,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。
● 搭配标准机箱尺寸
北亿纤通的CWDM复用&解复用LGX模块可以独立使用,也可搭配1U机箱运用,其LGX按1/3的19"机箱尺寸设计,在一台1U机箱上搭配3款该类或其他的LGX模块类型,增加1U机箱利用率。
● 符合国际标准
北亿纤通的CWDM复用&解复用LGX模块符合RoHs,满足TelcordiaGR-1209与GR-1221。
● 安装方便、标识清晰
北亿纤通的LGX模块盒与机箱的固定方式采用铆钉式固定扣,使用UL94V-2认可的尼龙料制成,方便安装与拆解;每个LGX模块面板工作端口均有激光打印的波长标识,方便用户识别。
