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