InGaAs PD Module

The UBD series ultra-low noise balance detector module is an upgraded product based on the original MBD series. Compared with the original MBD series, its background noise is significantly reduced under the same conditions of other parameters. Under the same bandwidth and gain conditions, its background noise is about one third of the MBD series module. Because of this, its sensitivity is higher and its signal to noise ratio is higher.
