Introduction:
Variable Gain Optical Receiver OE-300
The OE-300 optical receiver consists of a high-quality photodiode and a high-end variable gain transimpedance amplifier. Its low noise performance (NEP) is outstanding and sets a benchmark for broadband optical receivers, especially in high and mid-range gain settings. The relatively large detector size facilitates optical alignment and ensures very high coupling efficiency when using the SI model along with the optional available fiber adapter PRA-FC/SMA. Many additional features make the OE-300 the most versatile broadband optical receiver in its class.
