Product Description

Optical Fiber Integrated Tap Monitor Array Detector

Description

Lightwit's Integrated Tap Monitor Array (ITMA) W/I²C interface is a compact, multi-channel power- monitoring module. Functions of power reading, alarm and threshold setting are provided at firmware command level thru W/I²C interface. There is no hardware design, firmware programming or PD calibration work for user anymore, which greatly relieves user from heavy work load of design and manufacturing and provides great cost saving.
Lightwit can provide customized designs to meet specialized feature applications. Also, Lightwit offers modular assemblies that integrate other components to form a full function module or subsystem.
