The main technical indicators to evaluate optical passive devices are: insertion loss, return loss, bandwidth, with ups and downs, power allocation error, the wavelength isolation, channel isolation, channel width, extinction ratio, switching speed, speed and so on. Different devices have different requirements of technical indicators, but most of the optical passive devices need the requirements of low insertion loss, high reflection loss, and wide working bandwidth.
