CIPRM balanced receiver, Rev. 2016-01

Preliminary Data Sheet

Photon Detection

CIPRM series

Coherent InGaAs PIN balanced receiver module

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 well-

matched 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.
