The bit error rate (BER) measures the data transmission precision within a specified time period. Receiver sensitivity refers to the minimum input optical power required by the receiver to achieve a specified bit error rate (BER). Common reasons for bit errors include channel noise, signal interference, distortion, and transmitter-receiver clock synchronization errors.

OEM laser modules offering ultra-low noise or extreme miniaturization, with circular, elliptical, or fan line output for use in inspection, alignment, and instrumentation. Coherent's portfolio of high-speed transimpedance amplifiers (TIAs) delivers best-in-class signal integrity, high programmable gain, and exceptional power efficiency for optical interconnects ranging from 56Gbps to 224Gbps per channel. In recent years, advancements in technologies such as optical coherent communication, precision measurement, optical detection and ranging, have raised the bar for the coherence, power, noise, and other key pa-rameters of light sources. In this thesis, we mainly focus on the impact of laser phase noise arising from the transmitter and local oscillator (LO) lasers in coherent optical communication systems employing high order modulation formats.

Bit Error Rate (BER) is a critical performance metric in optical communication systems, representing the ratio of erroneous bits to the total number of transmitted bits. The different modulation techniques scheme is sugge ted for improvement of BER in fiber optic communications. BER is a key metric that measures the rate at which errors occur in data transmission, serving as a critical indicator of the system's performance.
