ASR2500 Fiber Satellite CWDM Optical Receiver

Ascent’s ASR2500 series is a compact fiber satellite and DTT optical receiver suitable for satellite optical network systems. The device receives the CWDM optical transmission signal from AST2500 transmitter, de-multiplexes them and distributes it to the end customer.

    Designed for Satellite Optical Systems                            

    Wide operating frequency range: 47 MHz to 860 MHz / 950 MHz to 2150 MHz

    Excellent Linearity and flatness

    Single-mode fiber high return loss

    Build-in GaAs amplifier active devices

    Ultralow noise technology

    Build-in CWDM, using high linear PD

    Outputs connected to satellite multiswitch

    Built-in optical AGC function

    Red LED for power indication

    Small size and easy installation
