SQOB-3000 Optical Receiver Block 40 - 3000 MHz

Query


The SQOB-3000 Optical Receiver Block is a single-mode fiber pigtailed module featuring a low-noise, impedance-matched broadband photodiode and RF amplification.

The device receives optical analog and/or digital signals for a range of video broadcast options, and delivers the corresponding RF electrical output. The wide bandwidth supports the delivery of signals up to 3000 MHz.

The device exhibits excellent distortion performance with values well above standards over the entire bandwidth and case temperature specifications ( - 40 to +85 °C).

The device can be used in both 1310 nm and 1550 nm applications being useful at different points of a given network.

The SQOB-3000 is compliant with all criteria of the Restriction of the Use of Hazardous Substances in Electrical and Electronic Equipment (RoHS) guidelines 2002/95/EC.
