NRZ output of optical transceiver module
High SMSR ensures clean signals in optical transceiver modules, reducing interference. Modulation dictates how data is encoded onto light. NRZ (Non-Return-to-Zero) is binary—0 or 1—prevalent in low-speed. GIGALIGHT 200G QSFP-DD SR4 optical transceiver modules are used for short-range interconnections between devices within data centers and are compliant with 200G Ethernet transport protocols, as well as compatible with 4×50G Ethernet transport protocols. Optical modules typically have an electrical interface on the side that connects to the inside of the system and an optical interface on the side that connects to the outside. Enter Non-Return-to-Zero (NRZ), a cornerstone modulation scheme that has powered decades of data transmission, particularly within the critical realm of optical transceiver technology. While newer, more complex schemes emerge to handle escalating bandwidth demands, NRZ remains remarkably relevant. Checking transceiver specification, NRZ or PAM4 are the common values for modulation. Read the article to learn what NRZ is and the difference between NRZ and PAM4. What is Non-Return-to-Zero (NRZ)? Non-return-to-zero (NRZ) is a binary digital signal modulation method applied in optical modules. While current widely used NRZ modulated (light On/Off) signals have 10-25G baud rate limitations and for long distance links we are used to deploy EDFA (Erbium-doped optical fiber amplifiers) and DCM (Dispersion Compensation Modules), which have their own limitations. -
