Rapid adoption of 5G technology and IoT devices has driven the demand for high data rate optical modules, especially from data centers for inter- and intra-communication purposes. Increasing the optical module data rate from the current 100Gbps to 400Gbps/800Gbps is an efficient way to upgrade the network infrastructure. PAM4 signal modulation and coherent technology are key for the new high data rate optical module design. To fulfill the tight design requirements of the new PAM4 type optical module, a high frequency, tight stability, low jitter, low power consumption, and small size differential crystal oscillator is very critical. As a leading company in Frequency Control Products, Taitien’s crystal oscillators are being used at the forefront of the optical module industry. Recently, we released a new series of crystal oscillators (OB-U series). Its ultra-low jitter performance (50fs typical, 100fs max), low current consumption, and smaller size (2.5 x 2.0 mm) make it the best fit for PAM4 type optical module designs for data centers, servers, and networking applications.
