1. For wavelengths within ±5 nm to the operating wavelength range, the worst-case changes in insertion loss and WDL are shown as follows:
tap ratio=1%, maximum insertion loss and WDL increase=0.65 dB
tap ratio=5%, maximum insertion loss and WDL increase=0.50 dB
tap ratio=10%, maximum insertion loss and WDL increase=0.40 dB
tap ratio=50%, maximum insertion loss and WDL increase=0.20 dB.
2. For connectorised components operating range is -5 to 75 °C. TDL is specified from -5 to 75 °C.
