1. A light detection and ranging (LIDAR) sensor system for a vehicle, the LIDAR sensor system comprising a transceiver, the transceiver comprising:
a plurality of inputs configured to receive one or more local oscillator (LO) signals and one or more light signals that are received from a laser source;
a plurality of transmitter (TX) outputs configured to transmit the one or more light signals into an environment of the vehicle through the plurality of TX outputs;
a plurality of receiver (RX) inputs configured to receive a first returned light and a second returned light reflected from one or more objects in the environment;
a plurality of first RX outputs configured to receive the first returned light and a first LO signal of the one or more LO signals; and
a plurality of second RX outputs configured to receive the second returned light and a second LO signal of the one or more LO signals,
wherein
the plurality of TX outputs and the plurality of RX inputs are located on a first side of the transceiver, and
the plurality of inputs are located between the plurality of first RX outputs and the plurality of second RX outputs on a second side of the transceiver.
