4 Apparatus
4.1 Source (S)
The source unit consists of an optical emitter, the means to connect to it and the associated drive electronics. A tunable light source (TLS) in which a specific output wavelength can be tuned may be chosen as the optical emitter. A TLS may consist of a tunable LD and an optical amplifier or a fibre ring laser. Generally, the power and stability requirements of the test will necessitate that the optical emitter has a fibre pigtail. It shall have a stable output power and wavelength/frequency over the measurement period. For DWDM devices, the frequency stability (instead of the wavelength stability) shall be less than half of the channel bandwidth. Unless otherwise stated in the relevant specification, the source shall have the following characteristics:
