In the CIPRM series balanced optical receiver Excelitas has the best features of high performance InGaAs photodiodes and low noise, high gain transimpedance amplifier to offer a practical solution to detect small changes above the interfering noise floor of incoming signal. The advantage is that the common optical noise is cancelled out.
This receiver incorporates two low-noise photodiodes with wellmatched responsivity, in order to ensure a high common mode rejection ratio (CMRR). It has two optical inputs (single mode fiber in -1 series and FC connectorized in -2 series), an RF output, electrical supply inputs and two photo-current monitor outputs.
The CIPRM modules come in a robust casing with flange mounting holes for securing the module to working surfaces or platforms. Combined with a wide operating temperature range, the CIPRM can work in some of the toughest and harshest environments.
Excelitas’ series of optical balanced receiver modules are designed and built to be fully compliant with the European Union’s RoHS Directive 2011/65/EU
