SQOB1228P 1.2GHz Optical Receiver Block

Query


The SQOB1228P is a high dynamic range optical receiver block with amplifier circuits. It has a single-mode optical input suitable for 1100 to 1650 nm wavelengths, a terminal to monitor the photo diode current and an electrical output having a characteristic impedance of 75 Ω.

The device package is complied with standard SOT-115 where the non-jacketed fiber has  an SC/APC or FC/APC connector.

The amplifier supply voltage pin and the photo diode bias voltage pin both connect to 24 V (DC).
