Note 1: Channel passband is defined as λITU ±0.11nm and subject to all the ITU passband related spec., such as insertion loss, passband ripple and isolation, etc.
Note 2: All insertion losses (or IL Uniformity) are specified no-connectors unless stated otherwise.
Note 3: Extra 0.5 dB IL will exist at 1370 ~1410nm band.
Note 4: Insertion loss of Test Tx here is defined as the optical power difference between the DeMux port input power and the Test Tx port output power.
