Oplink’s integrated tap monitor array (ITMA) is a compact, multi-channel power monitoring device. It increases module design flexibility and efficiency by significantly reducing the number of assembly components and facilitating fiber management.

ITMA integrates the functionality of an optical coupler and a photodiode while delivering low insertion loss and low dark current with high temperature stability over a wide operating wavelength range.

Oplink’s integrated TAP ITMA with I²C interface is a compact, multi-channel power-monitoring module. Power reading, alarm, and threshold setting functions are provided at a firmware command level through an I²C interface. There is no hardware design, firmware programming, or PD calibration work for users, which greatly relieves the user from a heavy work load of design and manufacturing, and provides great cost savings.
