Description

双窗耦合器（DWC）接纳非对称耦合手艺制造。通俗器件带宽可抵达±40nm，超宽带器件可扩展到±80nm。双窗宽带耦合器在1310nm和1550nm通讯窗口上具有相同的耦合比，以及具有低插入消耗和低PDL。该产品普遍应用于通讯系统、CATV和FTTH。

产品特征
● 低附加消耗，使器件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。
● 双窗带宽，通俗器件带宽可抵达±40nm，超宽带器件可扩展到±80nm。
● 尊龙凯时最新平台登录 的双窗耦合用具有成熟的生产工艺，支持-40℃~+85℃ 的卑劣情形下事情，性能稳固可靠。
● 尊龙凯时最新平台登录的双窗光纤耦合器切合RoHS，知足TelcordiaGR-1209与GR-1221。
