摘要 |
In an optical transmission system (Sa), a lens (112) converges an optical signal (OSin) outputted from a light emission element (111). The optical signal (OSin) having passed through the lens (112) enters a multi-mode fiber (MMF)(12). A vertex (Z0) of the lens (112) and an input plane (Fin) of the MMF (12) are at a distance (Z1). The distance (Z1) is set to a value which is not equal to the distance from the vertex (Z0) to the focal point (Zfp) of the lens (112). As a result, a low-cost optical transmission system can be provided in which the influence of mode dispersion is reduced. <IMAGE> |
