*At 23° C over bandwidth.
** Does not include connector, splice and fiber-end fresher losses.
*** IL is 0.3 dB higher, RL is 5 dB lower for each connector added. Optical Power will be 1W only with connector added.
****If tap port coupling ratio is ≤ 5%, ER will be 2dB lower; for ≤1% tap port, ER is out of concern(PM type).
