Product Description
Lightwit TAP PD is a small size optical power monitor that integrate a thin-film tap photo detector with pigtail, it have high linearity and high responsibility PIN photodiode and receive the 1510~1620nm wavelength.The products features: ultra compact and miniaturized structure, Low
capacitance, low dark current and high optical return loss. They are widely used in channel power monitoring in EDFA system, OADM system, DWDM system, in-line optical network switching protection and so on. This device is mounted into a coaxial package integrated with a single mode fiberpigtail without connector, FC, SC, ST or LC connector can be selected also.
