一种多波长光收发装置

Multi -wavelength light send -receiver device

Abstract

The utility model relates to a multi -wavelength light send -receiver device, including common port, transmitting terminal, receiving terminal and optical coupling portion, the transmitting terminal includes first transmitting terminal, second transmitting terminal, the receiving terminal includes first receiving terminal, second receiving terminal, optical coupling portion includes first light filter, second light filter, third light filter, fourth light filter, negative lens. The utility model discloses can obtain higher coupling efficiency through short optical distance, solve adjacent wavelength's interference and unable effective detached difficulty for the single fiber quadriversal transceiver module subassembly of intensive wavelength can be realized and effective use.
本实用新型涉及一种多波长光收发装置,包括公共端、发射端、接收端和光耦合部;所述发射端包括第一发射端、第二发射端;所述接收端包括第一接收端、第二接收端;所述光耦合部包括第一滤光片、第二滤光片、第三滤光片、第四滤光片、负透镜。本实用新型可以通过较短的光程获得较高的耦合效率,解决了相邻波长的干扰和无法有效分开的困难,使得密集波长的单纤四向收发模块组件得以实现和有效使用。
