Output IL = - 10 * log(1 - Tap Ratio) + E.L, E.Lwill be 0.2 dB higher if tap port is HI 1060 Fiber. IL is 0.5 dB higher, RL is 5 dB lower, and ER is 2 dB lower for each connector added. Connector key is aligned to slow axis. The optical path is aligned to slow axis and fast axis is blocked. The isolation is related to the input power.Please inform us when you need high isolation and operate above 30 mW.
