Optical power monitoring is essential in optical network for reconfigurable optical add/drop multiplexing (ROADM), network switching/protection, and gain/attenuation in amplification. Oplink's powering monitoring photodiode (PD) integrate PD with tap or WDM function into one compact package, provide not only space saving, but also higher performance and reliability. The power monitoring product family has pigtail integrated PD, tap or WDM PD in single channel and array packages.

Variable optical attenuators (VOA) are widely used for optical power management in multichannel optically amplified reconfigurable networks. - Oplink provides various VOA, from manually adjustable MVOA-T to Microelectrical Mechanical Systems (MEMS) based compact VOA.
